What Is MUM?
In 2021, Google announced the Multitask Unified Model (MUM), an advanced algorithm designed to understand information across multiple modalities—text, images, and eventually video and audio. MUM aims to answer complex, multifaceted questions by drawing from diverse data sources and languages.
It is trained on a much larger dataset than previous models and can transfer knowledge across languages, providing more comprehensive answers to users.
Passage Ranking Explained
Around the same time, Google introduced passage ranking, enabling it to identify and rank specific sections of a page rather than evaluating the entire page as a whole. This means that if a long article contains a concise answer to a query buried in the middle, that passage can still surface in search results.
This shift encourages writers to organise content with clear headings and coherent paragraphs that address individual subtopics.
Implications for Content Creators
To optimise for MUM and passage ranking, structure your content thoughtfully. Use descriptive headings, create distinct sections for each question or topic, and write in a way that’s easy for algorithms to parse.
Including multimedia—images, audio snippets, charts—can also make your pages more appealing to MUM’s multimodal capabilities. When answering complex questions, provide context and break down the problem into manageable parts.
Doing so helps search engines surface the most relevant passages, and it makes your articles more useful for readers who skim for specific information.
SEO Takeaways and Next Steps
MUM and passage ranking are significant leaps toward more intelligent search. By creating structured, comprehensive content and leveraging multimedia, you position your site to take advantage of these advancements.
