In 2009, a patent application described a different approach to website analysis: make the modeled evaluation system itself transparent and navigable. That application, US20090132524A1, became the foundation for U.S. Patents 8,447,751 and 9,245,037, both titled “Navigable Website Analysis Engine.”

Developed by Market Brew founder Scott Stouffer, the patented system was designed to crawl websites, analyze pages and links, calculate modeled search scores, and allow website publishers to explore how those scores were assembled.

At the time, search performance could be observed through rankings, traffic, and other outputs. What was much harder for publishers to inspect was the modeled evaluation process behind those outcomes.

The Navigable Website Analysis Engine approached that problem by turning search analysis into something users could move through, investigate, and revisit.

That idea became an early technical foundation for Market Brew’s approach to search engine modeling.

Why Make Search Analysis Navigable?

A website is evaluated through more than one isolated page or measurement.

Content, metadata, links, page relationships, site structure, relevance, and authority can interact across the site. Yet many forms of website analysis ultimately reduce those relationships to a report, score, or list of recommendations.

The patented system took a different approach. Rather than showing only an overall result, it was designed to let a user investigate the modeled system behind it.

A publisher could begin with a website, move into an individual webpage, inspect measurements associated with ranking factors, and continue deeper into the links, penalties, or page-level information contributing to those measurements.

In simplified form, the model created a path such as:

Website → webpage → ranking factor → link or page-level detail

The system could also expose information about the methodology and data associated with individual measurements.

The result was not simply a score assigned to a website. It was an environment that could be explored.

The Navigable Website Analysis Engine

The defining concept in the patents is contained in the name itself: navigable.

The modeled evaluation was organized into connected layers.

At the site level, a user could understand the broader condition of the website. From there, the analysis could move into individual webpages and the factors contributing to their modeled scores. Link-level information could then show how other pages or external sources contributed to those results.

This allowed users to trace relationships through the model rather than treating each measurement as an isolated finding.

That distinction is important.

If one page received a different modeled score than another, the system was intended to provide ways to investigate why. A user could move deeper into the measurements and supporting information rather than being left with an unexplained output.

Transparency made the scoring system more inspectable.

Navigability made the relationships behind that scoring easier to investigate.

What the Patented System Modeled

The patents describe analysis across page-level, link-level, and sitewide information.

At the page level, the system could evaluate content and relevance, metadata, duplicated information, missing page elements, and other measurable conditions associated with a webpage.

At the structural level, it could represent relationships among pages, including navigation, orphaned pages, and the broader organization of the website.

Links received their own treatment inside the model. Incoming links, outgoing links, link-level measurements, and their contribution to broader webpage scores could all be incorporated into the analysis.

Together, these measurements created an interconnected representation of the website.

That system-level perspective is one of the ideas that continues to distinguish Market Brew’s approach today: a page does not exist independently from the links, structure, content, and other pages surrounding it.

One of the concepts described within this work is Link Flow.

The patented scoring system incorporates link authority into its evaluation of webpages, creating a way to represent how authority moves through links and accumulates across a website.

That makes internal linking part of a larger system rather than simply a checklist item.

Pages can receive different levels of modeled support depending on where they sit within the linking structure, which other pages connect to them, and how authority is distributed throughout the site.

A page with strong content may still occupy a relatively weak position if the surrounding website provides limited support to it. Another page may accumulate considerably more authority because of its position within the site's internal relationships.

Link Flow became one of the recognizable concepts associated with Market Brew’s approach to website analysis and remains part of how the platform evaluates authority across connected pages.

Recrawling and Rescoring the Model

The Navigable Website Analysis Engine was also designed to support repeated analysis.

After website information changed, a user could request another crawl. The updated pages, links, and measurable conditions could then be processed and the modeled scores recalculated.

This extended the idea beyond a static website report.

Transparency made the model inspectable. Recrawling and rescoring made it repeatable.

A website could change, the modeled environment could be rebuilt, and the resulting measurements could be compared with the earlier state.

That inspect-and-rescore methodology helped establish a technical foundation for the broader testing approaches that Market Brew would develop over time.

The modern platform extends those ideas considerably, but the underlying principle was already present: search analysis could function as an environment that changes as the website changes.

What the Original Patents Did (and Did Not) Model

The patented system focuses on information that can be crawled, calculated, and represented within its model.

The patent materials describe areas including:

  • Webpage content and relevance
  • Metadata and missing page information
  • Incoming and outgoing links
  • Link Flow and link-level authority
  • Duplicated or low-value information
  • Page relationships and navigation
  • Sitewide structure

The materials also acknowledge boundaries.

Factors such as dwell time and user “stickiness,” for example, were identified as outside the scope of the original system. That distinction helps define what the technology was intended to do.

The Navigable Website Analysis Engine was not presented as an exact reproduction of every signal a live search engine might use. It created an inspectable model from website information that could be observed, processed, scored, and connected.

That principle remains important when discussing search engine modeling today: a model is valuable because it provides a structured representation of a complex system, not because it claims perfect equivalence with that system.

Recognition Across Search and Web Technology

The original patent has since appeared in later patent filings across search, enterprise technology, content management, website platforms, and SEO software.

The citation record associated with the patent includes organizations such as Google, Microsoft, Yahoo, IBM, Baidu, BrightEdge, and Wix. It has been called “one of the most cited SEO patents" (yes, even by Google)!

Those later filings cover a range of adjacent technological problems.

For example, the patent has appeared in work involving web crawling, document and content representation, website structure, content management, and SEO-oriented website systems.

Patent citations should not be interpreted as endorsements of Market Brew or its technology. They do, however, show that the Navigable Website Analysis Engine became part of the prior-art record considered in later work across several areas of search and web technology.

That gives the patents an important role in Market Brew’s technical history: they document an early attempt to make website scoring, link analysis, and search-oriented evaluation more transparent and navigable for website publishers.

How the Patents Connect to Market Brew Today

Market Brew has evolved substantially since the original patent application was published in 2009.

Search systems have changed. Website architectures have become more complex. Semantic analysis, modern ranking systems, AI retrieval, and enterprise-scale optimization have expanded the types of signals and relationships that SEO teams need to understand.

But several principles established in the patents remain recognizable.

Websites are modeled as connected systems.
Pages, links, authority, content, and structure influence one another rather than existing as isolated measurements.

Modeled scoring should be inspectable.
Users should be able to investigate the factors and relationships associated with an outcome rather than relying only on an unexplained score.

The modeled environment can be revisited as the website changes.
Recrawling and rescoring created an early framework for studying how changes alter the modeled representation of a site.

Those principles became part of the technical lineage behind Market Brew’s modern search engine modeling technology.

Today, Market Brew builds modeled search environments around websites, competitors, queries, content, authority, structure, and other signals associated with visibility. The modern system extends well beyond the scope of the original patents, but the goal of making search analysis transparent, navigable, and inspectable remains central.

From Technical Foundation to Modern Search Modeling

The Navigable Website Analysis Engine represents an early chapter in Market Brew’s development.

Its importance is not that every modern Market Brew capability appeared fully formed in the original patent.

It is that the patents established a particular way of approaching search analysis: build a model, expose the measurements inside it, preserve the relationships between pages and links, and allow users to investigate how the modeled result was produced.

Market Brew has continued building on that foundation as search has evolved.

For teams deciding which modeled improvements deserve investment, our SEO forecasting guide explains how that understanding can support comparisons between future SEO initiatives.

The patents provide the provenance behind both: a search-analysis system originally designed to make modeled evaluation something publishers could see, navigate, and investigate.
