Firstly, compared to its predecessors, Google's MUM has an advanced ability to comprehend context, which means it doesn't just match keywords, but also interprets the semantics and intent behind search queries. This means that content, long-form or otherwise, will need to be more in-depth and intelligently crafted to provide comprehensive answers to user queries. SEO practitioners will need to ensure their long-form content is well-researched, thorough, and centers upon delivering value to the reader.
Long-form content has always been beneficial from an SEO standpoint because it provides more opportunities for keyword targeting, offers more comprehensive information, and tends to keep visitors engaged for longer. However, with MUM, this takes on an added dimension. Given MUM's multitask abilities, it can simultaneously analyze text across different languages and formats, thereby understanding and pulling together information on a wider scale. Long-form content with comprehensive detail is more likely to be recognized by MUM as a valuable piece, increasing its chances of being considered for a higher rank.
Additionally, MUM’s ability to parse complex, multipart search queries necessitates a more nuanced and extensive response. The specific, multi-faceted answers that users demand can rarely be satisfied by short, simplified content pieces. Long-form content typically delves deeper into the topic, with various sections addressing different aspects of the subject matter. This in-depth presentation style aligns perfectly with MUM's capacity for handling complex queries.
For example, if a user looked up “What are the similarities and differences between apple and orange in terms of nutritional value, taste, and culinary use?”, a long-form piece, which systematically breaks down the comparative attributes, would stand a higher chance of ranking as it would check all the boxes for MUM's understanding of the user's complex, multi-layered query.
However, the key here lies in realizing that MUM does not make long-form content imperative for SEO outrightly. Not all topics warrant a detailed deep-dive, and unnecessary padding of information will not get brownie points from MUM. The focus rests on providing complete, valuable content. If the user query can be answered comprehensively in just a couple of paragraphs, Google's MUM will still view it as relevant.
While MUM does place considerable emphasis on the comprehensiveness of content, which often coincides with long-form pieces, the key takeaway for SEO professionals is that relevance, depth, and value must drive content creation, whether it’s short form or long. MUM enhances the importance of insightful, helpful content, and SEO strategies must evolve to understand and match this intent better.
