How a Search Engine Recognizes Parasite SEO

The term "parasite" in Parasite SEO is derived from biological parasites, which rely on a host for sustenance without offering any benefit in return, often harming the host in the process. In the digital world, the host websites could include popular platforms like news sites, educational forums, high-domain authority blogs, or social media platforms, all of which hold a robust standing in search engines like Google.

How does Parasite SEO operate? Practitioners of this approach create content such as articles, blog posts, discussion threads, or user profiles on these high-authority sites. This content includes backlinks to the parasite’s target, which might be their website or a client's site. Since search engines, notably Google, place a high value on backlinks from authoritative sites, these links have the potential to drastically boost the search rankings of the parasite's target site, all while exploiting the host's established SEO power.

The method takes advantage of the host's search engine trust level. Search engines assume that content on reputable sites is trustworthy and valuable, so links from these sites are weighted heavily. As a result, the parasite site can see a quick, significant bump in its search rankings. The effect is particularly potent when the content on the host site ranks well for competitive keywords, thereby directing considerable traffic to the parasite's linked pages.

Parasite SEO is often seen in various forms. For example, posting guest articles on popular blogs with backlinks to the perpetrator's site, creating profiles on professional sites like LinkedIn with links embedded in the biography section, or utilizing user-generated content areas of highly trafficked websites to include links in forum posts or comments.

However, engaging in Parasite SEO is not without risks. Major search engines, such as Google, have become increasingly adept at identifying and penalizing this practice. The Google algorithm updates routinely enhance the ability to detect unnatural linking patterns and other indicators of manipulative practices. When detected, both the parasite and, sometimes, the host site can suffer penalties. These penalties might range from a drop in rankings to a complete ban from search index listings, significantly impacting traffic and digital reputation.

Beyond the immediate technical workings and potential repercussions, Parasite SEO highlights a broader conversation about ethical digital marketing practices. While the pressure to achieve high rankings quickly can be intense, resorting to manipulative tactics like Parasite SEO ultimately undermines the trustworthiness of the web and the fairness of search competitions. Practitioners of digital marketing are encouraged to pursue sustainable, ethical SEO strategies that contribute positively to the web ecosystem and ensure a stable, long-term ranking improvement. Focusing on content quality, user experience, and natural link-building within the rules set by search engines is advised to avoid the pitfalls associated with Parasite SEO.

Let's delve into some of the most common examples of Parasite SEO tactics used to manipulate search engine results unfairly.

1. Hijacking High Authority Web Pages: one common method of Parasite SEO involves taking advantage of user-generated content (UGC) areas on high authority websites. Perpetrators might create profiles, post articles, or leave comments on popular forums, blogs, or social media platforms. Unlike normal guest posting or commenting, these activities involve stuffing links and using manipulative anchor text to influence search rankings.
2. Creating or Exploiting Existing Landing Pages: operators might create landing pages on high-domain-authority sites such as educational domains, non-profit organizations, or popular community pages. These pages are crafted specifically to harbor outbound SEO links. In more insidious scenarios, parasites find and exploit existing pages that have been neglected but still carry substantial page authority, inserting malicious links or redirecting the page’s traffic to unwanted destinations.
3. Using Expired or Hacked Domains: another tactic is to utilize expired domains that still possess SEO value due to their past references on credible sites. These domains are bought and repurposed to serve as hosts for links or as redirect agents to other dubious sites. Some parties go so far as to hack into legitimate websites to inject parasitic links without the knowledge of the original site owners.
4. Buffer Sites: buffer sites come into play when the parasite creates several intermediary web pages or sites (such as blogs, info pages, or social media pages) on reputable domains to create a link chain. These buffer sites link to each other in a tiered structure, ultimately pointing towards the final target site. This method helps dilute the obviousness of direct link placements from authority sites to the target.
5. Syndicating Spun Articles: article syndication involves distributing articles across various platforms to gain backlinks. In the context of Parasite SEO, this tactic is taken to an unethical level by spinning or slightly altering existing content (a technique that rephrases existing articles to avoid plagiarism detection). These spun articles are then posted across different high-authority sites to maximize backlink impact.
6. Misusing Press Releases: historically, press releases were a legitimate way to announce significant events while naturally earning backlinks from coverage. However, in Parasite SEO, press releases are overused, distributing low-quality, spammy content across multiple high-authority news domains purely for the sake of embedding backlinks.

The aforementioned examples illustrate various ways individuals apply Parasite SEO tactics, exploiting the domain authority of respected sites to boost less reputable or entirely new websites in search engine rankings. This approach not only does disservice to the host sites by potentially damaging their reputation but also pollutes the search engine ecosystem, deteriorating the quality and relevance of search results for users.

Major search engines like Google continuously refine their algorithms to penalize such activities, and the implementation of these tactics can have long-term detrimental effects on the SEO health of the perpetrator’s sites. Both ethical concerns and pragmatic risks make Parasite SEO an ill-advised strategy for any serious digital marketer or business. Ethical SEO practices involve creating genuinely valuable content and building natural link relationships, fostering a healthier, more useful internet for everyone.

Understanding the divergence between these two forms is critical for digital marketers, website owners, and SEO specialists, as each brings unique implications and potential consequences. 

Page-Level Parasite SEO, as the term implies, manifests at the page level. It involves the insertion of unrelated, often manipulative chunks of content onto a webpage that typically focuses on an entirely different topic. For instance, a high-ranking article about "Healthy Diet Plans" might suddenly sport a paragraph or a section about "Affordable Vacation Destinations," complete with links to external websites promoting travel packages. Such content is not only contextually out of place but intentionally engineered to piggyback on the page’s existing authority and traffic, thereby siphoning SEO benefits such as backlinks and Google ranking improvements to other domains with which it shares a symbiotic, albeit unethical, relationship.

This tactic capitalizes on the authority of individual pages. Since search engines often rank pages rather than entire websites, leveraging a high-traffic page ensures that the irrelevant injected content gains undeserved visibility and SEO merit. However, this method can severely disrupt user experience, leading to confusion and frustration amongst visitors and significantly increased bounce rates.

Conversely, Website-Level Parasite SEO operates on a broader scale by dedicating entire pages of a website to off-topic content. Unlike Page-Level, where disparate chunks of content disrupt a singular page, Website-Level involves the creation or transformation of whole pages that deviate from the website’s core theme or purpose. For example, a website dedicated to literary book reviews might host a series of pages about trendy electronic gadgets, entirely unrelated to its primary focus. Each of these pages might target specific, high-volume keywords to capture traffic from search engines, again leveraging the site’s overall domain authority to boost unrelated content.

This broader approach can profoundly impact the overall coherence and perceived expertise of the website, potentially damaging its credibility and undermining the trust of its audience. Moreover, as search engines advance and refine their algorithms to prioritize topic consistency and expertise, such tactics could lead to site-wide penalties and a significant loss in search rankings.

Both Page-Level and Website-Level Parasite SEO share a common goal: to exploit high domain or page authority for the benefit of unrelated content. However, their strategies and the breadth of their execution differ significantly. Page-Level is more surgical, inserting unrelated SEO-advantageous snippets into specific authoritative pages, whereas Website-Level is more architectural, building entire sections of a site around off-target themes.

Both forms of Parasite SEO present ethical challenges and risks. Search engines like Google constantly update their algorithms to penalize such practices, recognizing them as manipulative and detrimental to user experience. Websites caught employing either tactic can face severe repercussions, including ranking penalties and loss of organic credibility and authority.

For stakeholders in the digital domain, understanding the nuances between Page-Level and Website-Level Parasite SEO is crucial. It informs not only strategic and ethical SEO practice but also fortifies defenses against competitors who may use such tactics to gain unwarranted advantages. As the digital landscape continues to evolve, adherence to ethical SEO practices becomes more critical, ensuring fair competition and preserving the integrity of the web ecosystem.

The immediate effect of utilizing Parasite SEO is often a spike in rankings. This occurs because search engines, like Google, view links from high-authority sites as endorsements, thereby temporarily enhancing the perceived value and trustworthiness of the linked site. However, this is an illusion of success, as search engines continually update and refine their algorithms to identify and penalize such manipulative tactics.

Once a search engine identifies that a site has gained rankings through unethical means, such as Parasite SEO, the repercussions can be severe. The first and most immediate impact is the potential for a sharp decline in rankings. Search engines aim to provide users with the most relevant and trustworthy information, and when a site is flagged for using deceitful tactics, its ability to rank well in search results is significantly diminished. This can lead to a dramatic drop in organic traffic, which for many businesses translates directly into reduced revenue.

Moreover, repeated offenses or particularly egregious exploitation of Parasite SEO can lead to more severe sanctions, such as the website being blacklisted or entirely de-indexed from search engine results. This is a catastrophic outcome that essentially renders the site invisible on the web, completely obliterating its organic reach.

The repercussions of Parasite SEO extend beyond just search engine penalties. There's also a reputation risk involved. Customers and other businesses are more knowledgeable about SEO tactics than ever, and being associated with unethical practices can tarnish a brand's reputation. This perceptual damage can lead to decreased customer trust and loyalty, potentially harming long-term business relationships and discouraging new customer acquisition.

Additionally, using Parasite SEO can create a dependency on unsustainable practices for SEO success. Instead of developing a robust, long-term SEO strategy that focuses on quality content, user experience, and ethical backlink building, businesses may become overly reliant on exploiting host websites. Such a strategy is precarious at best; not only does it leave businesses vulnerable to changes in search engine algorithms, but it also diverts resources away from more sustainable and rewarding SEO efforts.

It is clear that while Parasite SEO might offer a temporary boost in website rankings, the long-term consequences are dire and counterproductive. The risks of severe penalties, loss of reputation, and the potential for being blacklisted are high stakes for any business. To thrive in the digital landscape, adopting ethical SEO practices that comply with search engine guidelines and focus on providing genuine value to users is essential. This approach not only ensures stable, lasting success in search rankings but also fosters a credible and trustworthy online presence.

Here, we explore several early indicators that may suggest the presence of Parasite SEO on a website.

1. Sudden Spike in Backlinks: one of the clearest signs of Parasite SEO is an unexpected and significant increase in the number of backlinks to your site. These backlinks often originate from dubious sources or sites that are irrelevant to your website’s content or industry. Utilizing tools like Google Search Console or third-party services such as Ahrefs or SEMrush can help you monitor and audit backlinks, identifying any unusual spikes or questionable sources.
2. Changes in Traffic Patterns: another indicator is a dramatic shift in website traffic, particularly from regions or user demographics that do not align with your target audience. Parasite SEO may redirect or funnel irrelevant traffic to your site, which can initially appear as an improvement in traffic metrics but often results in higher bounce rates and lower engagement, ultimately harming your website’s reputation and SEO standing.
3. Unexpected Content Modifications: monitoring your website consistently is crucial as Parasite SEO may involve alterations to existing content or the addition of new, unauthorized content. This could include injected spammy links, keywords out of context, or entire articles and blog posts that don't match your website’s tone, style, or thematic relevance. Such modifications could be subtly embedded, making regular audits of your site’s content a necessity.
4. Google Search Console Alerts: Google provides tools to help webmasters maintain the health of their sites. Receiving unexpected security or manual action alerts from Google Search Console can be a warning of potential Parasite SEO activities. These alerts often pertain to spammy content or unnatural links, suggesting that your site might be compromised or misused by third parties.
5. Performance Fluctuations in SERPs: noticeable inconsistencies or fluctuations in search engine results page (SERP) positions can also indicate Parasite SEO. If your website inexplicably falls in ranking for certain keywords, or if there are erratic changes in your SERP standings without clear reason, it may be due to manipulative SEO practices linked to your site either directly or indirectly.
6. Complaints or Feedback from Users: finally, feedback from users can sometimes alert you to issues caused by Parasite SEO. Visitors may report strange redirects, unsolicited pop-up ads, or other unusual site behavior which may have been induced by a third party exploiting your site’s SEO.

Being proactive is essential in guarding against Parasite SEO. Regularly monitoring these key aspects of your website can help identify the early signs of such unethical SEO tactics. Implementing a comprehensive security protocol, regularly updating software, auditing backlinks, and monitoring analytics should be integral parts of your SEO strategy to safeguard your site’s integrity and ranking. Addressing these issues promptly can mitigate the impact on your website and maintain your site’s health and reputation in the long run. By keeping an eye on these warning signs, you can ensure that your site maintains its credibility and SEO strength in an increasingly competitive digital world.

Here's an in-depth look at how these algorithms work to detect and address Parasite SEO.

Detection through Complex Algorithmic Checks

The first step in combating Parasite SEO involves detection. Search engine algorithms are equipped with numerous complex checks that scrutinize various aspects of each site and its content. One primary focus is the analysis of inbound and outbound links. Algorithms assess the quality, relevance, and natural flow of links to and from a web page. In the case of Parasite SEO, a sudden spike in inbound links from high-authority domains can be a red flag, especially if those links appear in irrelevant contexts or are surrounded by poor-quality content.

Furthermore, content quality algorithms such as Google’s Panda update play a crucial role in detecting SEO misuse. These algorithms evaluate the quality and originality of content on websites. Parasite SEO often involves duplicative content or keyword stuffing in articles that seem superficially relevant but offer little value upon closer inspection. By prioritizing content quality, search engines can demote pages that are suspected of hosting parasite content.

Contextual and Behavioral Analysis

Search algorithms have become significantly adept at contextual and behavioral analysis. This involves understanding the natural interconnectivity between sites in the same niche and scrutinizing any anomalies. For instance, if a highly authoritative educational site suddenly links to a commercial site selling products with little to no educational relevance, it might trigger further inspection by search algorithms.

Search engines also look at user behavior signals, such as bounce rates and click patterns, to judge the legitimacy of a site’s SEO practices. An unusually high bounce rate on backlinking pages might suggest that visitors did not find the content useful or relevant, an indicator often associated with Parasite SEO tactics.

Penalization and Notification

Upon detecting Parasite SEO, search engines take action to ensure such tactics do not offer an unfair advantage. The immediate consequence typically involves penalizing the offending websites by significantly dropping their rankings. This act serves both as a correctional and a deterrent measure. Algorithms are designed to continuously monitor penalized sites even after they drop in rankings, ensuring they do not employ similar tactics again.

In addition to penalization, search engines often notify webmasters of the detected manipulative behavior through tools like Google Search Console. This notification helps website operators to identify and remove such content themselves, aiming to restore their rankings by aligning with SEO best practices.

Continuous Learning and Updating

The fight against Parasite SEO is ongoing. Search engine algorithms are not static; they are continually updated based on new data, tactics discovered, and the evolving web environment. Machine learning plays a significant role here, as algorithms learn from new instances of Parasite SEO and automatically adjust their detection processes for better efficacy in the future.

Algorithms detect and address Parasite SEO through a multifaceted approach involving link analysis, content evaluation, contextual and behavioral insights, and continuous learning. These mechanisms work in concert to maintain the fairness and relevance of search results, ensuring that genuine content creators and marketers can compete on an even playing field. As search engines refine these algorithms, the message is clear: the only sustainable way to achieve and maintain high rankings is through ethical and quality-focused SEO practices.

Here are critical steps you should take if you find your website compromised by Parasite SEO tactics:

1. Conduct a Comprehensive Site Audit: the first step in addressing parasite SEO is to conduct a thorough audit of your website. Use tools such as Google Search Console, Ahrefs, or SEMrush to analyze your backlinks and traffic sources. Look for unusual spikes in traffic or an influx of low-quality backlinks, as these can be indicators of parasite SEO.
2. Identify and Remove Malicious Content: once you've conducted the audit, pinpoint any unauthorized content that might have been added to your site. This content often includes spammy posts, hidden texts, or suspicious backlinks. Tools like Google Analytics can help track down these anomalies by showing referral sources and the pages they are directed to. Removing these elements quickly is crucial to mitigate any damage.
3. Update Security Measures: parasite SEO often exploits vulnerabilities in your website's security. To prevent further incidents, update all your website’s software, apply the latest patches, and strengthen your website credentials. Consider using website security tools like Sucuri or Wordfence if your site runs on WordPress. Regularly changing passwords and implementing two-factor authentication will also fortify your website's defenses against unauthorized access.
4. Disavow Toxic Backlinks: if removing malicious backlinks is not possible—for instance, if they are generated from sites outside your control—you should disavow these links using Google’s Disavow Tool. This action tells Google to ignore these links when assessing your site. Submitting a disavow file can be a technical process, so it may be wise to consult with an SEO professional to ensure it's done correctly.
5. Monitor Your Site’s Progress: after cleaning up your site and updating your security measures, monitor your website's performance and rankings closely. Set up regular audits and keep an eye on your search rankings and traffic patterns for any further anomalies. This will help you catch any potential recurrence early and react promptly.
6. Report the Abuse: if you can identify where the parasite links or content are coming from, it might be beneficial to report this to the host platform. For instance, if spammy posts are originating from a particular blog or forum, contact the administrators to alert them of the misuse of their platform.
7. Educate Your Team: ensure that everyone involved in managing your website is aware of the signs of parasite SEO and understands the importance of maintaining security protocols. Regular training and updates on the latest security and SEO practices can help safeguard your site from future attacks.
8. Consider Professional Help: if the situation is severe or if you're unsure of how to handle parts of the cleanup and recovery process, it may be wise to hire a professional SEO service or a cybersecurity firm. These experts can provide the necessary guidance and take effective measures to restore the health and security of your website.

Taking these steps not only helps in recovering from the immediate effects of parasite SEO but also fortifies your website against future attacks, reinforcing your site’s credibility and the trust of your visitors. The key is prompt action and continual vigilance to maintain a clean, secure, and well-optimized website.

Parasite SEO involves leveraging the high domain authority of reputable websites to boost the SEO ranking of a lesser-known website. This is typically done by inserting links to the lesser site within content on the reputable sites without proper endorsement or relevance. This method exploits the host's credibility and trust to misleadingly enhance the visibility of the parasitic website.

When Google identifies a website engaging in Parasite SEO, the penalties can be severe and varied, depending on the extent and nature of the violation. Here's how Google penalizes such activities:

1. Manual Actions: Google's team of reviewers can impose manual penalties after reviewing a site that appears to be using Parasite SEO. These manual actions are applied to sites that fail to comply with Google’s Webmaster Guidelines. Once a manual action has been placed, the site may be demoted in search rankings or removed entirely from Google's search results. The website owner will receive a notification through Google Search Console about the manual action, detailing the specific reasons and possibly providing suggestions for recovery.
2. Algorithmic Adjustments: Google uses several algorithms designed to automatically detect suspicious or manipulative activity, including updates like Penguin, which specifically targets link spam. These algorithms can diminish the search visibility of websites using Parasite SEO by lowering their rank or completely filtering them out from the search results. Unlike manual actions, these adjustments are automated and can happen without direct notification, leaving webmasters to discern the cause based on observed traffic drops.
3. Devaluing Links: Rather than penalizing the website directly, Google may opt to simply devalue the inbound links generated through Parasite SEO. This means those links will no longer contribute to the website’s ranking power. By neutralizing the effects of these unauthorized links, Google reduces the incentive to employ such tactics without imposing direct penalties on the whole site.
4. Loss of Trust: Beyond the technical penalties, engaging in Parasite SEO can lead to a longer-term degradation in a site's trustworthiness in the eyes of Google. This can result in a sustained decline in rankings, making recovery and future SEO efforts more challenging.

Recovery from these penalties typically requires a thorough cleanup of the Parasite SEO practices, including removal of spammy links and submitting a reconsideration request if a manual action was applied. Websites must also commit to adhering to Google’s Webmaster Guidelines going forward, focusing on creating high-quality, relevant content and obtaining legitimate backlinks.

Google’s measures against Parasite SEO are aimed at preserving the quality and credibility of its search results. These penalties highlight the importance of ethical SEO practices, encouraging webmasters and SEO professionals to pursue strategies that contribute positively to the internet ecosystem, enhancing user experience and ensuring fair competition in search rankings.

Here are some long-term consequences of parasite SEO:

1. Search Engine Penalties and Loss of Rankings: The most immediate and devastating consequence of employing Parasite SEO is the potential for harsh penalties from search engines like Google. Search engines have sophisticated algorithms designed to detect and penalize websites that employ manipulative tactics to boost rankings. These penalties can range from a temporary loss in ranking to a complete de-indexing of the website from search engine results. Recovery from such penalties is not only difficult and time-consuming but also requires considerable investment in cleaning up the website’s backlink profile and revamping its SEO strategy.
2. Reputational Damage: The reputation of a business is crucial to its survival and growth. Parasite SEO, by its nature, can lead to serious reputational risks. When customers and clients discover that a business has engaged in unethical practices to manipulate search results, trust is eroded. This mistrust can spread through word of mouth and social media, leading to a loss of existing and potential customers, which directly affects revenue. Rebuilding trust, once lost, is an uphill battle that many businesses may not win.
3. Vulnerability to Algorithm Updates: Search engines like Google frequently update their algorithms to provide the most relevant and high-quality results to users. These updates often specifically target websites that have employed techniques like Parasite SEO. Websites relying on unethical SEO practices are thus always at risk of being negatively impacted by these updates. The constant fear of being caught each time an algorithm update rolls out can lead to a volatile business model where website traffic and ranking are never stable.
4. Resource Drain: Recovering from the impact of Parasite SEO consumes significant resources, including time, money, and effort. Businesses caught using these tactics often need to hire SEO recovery experts to help remove bad links, create quality content, and develop legitimate backlink strategies, all of which are essential to regain the lost ground. Moreover, during the recovery period, the website may experience reduced traffic, which in turn could lead to decreased sales and profits.
5. Ethical and Legal Implications: Beyond SEO, there are broader ethical and sometimes legal implications associated with the use of deceptive practices like Parasite SEO. Such tactics might violate terms of service of many platforms and can lead to legal action from those entities harmed by the malpractice. Furthermore, companies advocating ethical business practices are less likely to engage with or partner with businesses known for using manipulative SEO strategies.

While the temptation to jump the SEO queue through Parasite SEO might seem enticing, the long-term consequences make it a risky and ultimately harmful strategy. The risks of search engine penalties, reputational damage, and the significant resources required for recovery far outweigh the temporary benefits. Instead, businesses should invest in building a robust and ethical SEO strategy that yields sustainable results over time, bolstering their reputation and ensuring steady growth in the highly competitive digital marketplace.

Here are several proven alternatives to Parasite SEO that not only comply with search engine guidelines but also promote a robust digital presence.

1. Quality Content Creation: The cornerstone of any effective SEO strategy is high-quality content. Unlike Parasite SEO, which leverages existing authoritative platforms, creating original, valuable content can naturally attract traffic and encourage organic backlinks. Content that educates, informs, or entertains your audience increases engagement and shareability, which are key factors in boosting search engine rankings. Regularly updating your website with fresh content also signals to search engines that your site is relevant, improving visibility in search results.
2. Guest Blogging with Integrity: Rather than hijacking another site’s authority unethically, guest blogging involves publishing content on reputable sites with the consent and cooperation of the host. This practice not only helps build professional relationships but also allows you to tap into the host’s audience, offering mutual benefits. When done correctly, guest blogging enhances your credibility and amplifies your reach. It’s crucial to choose partners that resonate with your brand’s values and have a legitimate audience interested in your offerings.
3. On-Page SEO Optimization: Optimizing individual web pages to rank higher and earn more relevant traffic in search engines is a bedrock of ethical SEO. This includes optimizing content, HTML tags, headlines, and images. Simple adjustments like improving meta descriptions, using alt text for images, and ensuring that content includes relevant keywords can significantly affect organic traffic and user engagement.
4. Utilizing Social Media Platforms: Social media doesn’t directly impact SEO rankings, but the proliferation of content across these platforms increases brand visibility and traffic to your website. By engaging with your audience on platforms like Twitter, Instagram, Facebook, and LinkedIn, you can organically amplify your content’s reach and attract more visitors to your site. This strategy relies on high-quality content and active engagement rather than exploiting the search algorithm.
5. Building Relationships for Organic Link Building: Ethical link building is about fostering relationships with other industry players who will naturally want to link to your site because of the quality of your content and the reciprocity of the relationship. This could be through collaborations, interviews, joint ventures, and more. This practice contrasts sharply with Parasite SEO as it’s based on mutual benefits and genuine relevance to linked content.
6. Improving User Experience (UX): SEO isn’t just about attracting users to your site; it’s also about keeping them there. By improving the user experience, including faster load times, mobile responsiveness, and intuitive navigation, visitors are more likely to stay on the site longer and visit multiple pages. This decreases bounce rates and increases the average time on site, both of which are factors that search engines take into consideration when ranking sites.

While the allure of quick gains in SEO might tempt some into dubious strategies like Parasite SEO, the risk to reputation and the potential penalties make them unsustainable. Adopting ethical SEO practices not only fosters a positive brand image and builds trust with your audience but also contributes to a healthier, more equitable internet ecosystem. These strategies ensure consistent growth and stability in your SEO efforts, standing the test of time and algorithm changes.
