At Google I/O 2021, Google revealed a new technology called MUM (Multitask Unified Model) that it will utilize internally to help its ranking systems better understand language.
Since the statement, there has actually been much conversation about if or when MUM would become a ranking element.
What Is MUM?
Called “a new AI turning point for comprehending details,” MUM is created to make it much easier for Google to address complex needs in search.
Google assures MUM will be 1,000 times more powerful than its NLP transfer learning predecessor, BERT.
MUM utilizes a model called T5, the Text-To-Text Transfer Transformer, to reframe NLP tasks into a combined text-to-text format and develop a more comprehensive understanding of knowledge and info.
According to Google, they might apply MUM to document summarization, concern answering, and category jobs such as sentiment analysis.

When Google first exposed the news about MUM, many who read it naturally questioned how it may affect search rankings (specifically their own).
Google makes thousands of updates to its ranking algorithms each year, and while the large bulk go undetected, some are impactful.
BERT is one such example. It was rolled out worldwide in 2019 and hailed the most significant upgrade in five years by Google itself.
And sure enough, BERT impacted about 10% of search queries.
RankBrain, which rolled out in the spring of 2015, is another example of an algorithmic upgrade that substantially affected the SERPs.
Now that Google is discussing MUM, it’s clear that SEO experts and the clients they serve need to keep in mind.
Roger Montti recently blogged about a patent he thinks might provide more insight into MUM’s inner operations. That makes for an interesting read if you wish to peek at what may be under the hood.

“Today’s online search engine aren’t quite advanced sufficient to address the way a professional would. But with a new technology called Multitask Unified Model, or MUM, we’re getting closer to helping you with these kinds of complex needs. So in the future, you’ll require less searches to get things done.”
Then, the timeline offered when MUM-powered functions and updates would go live became “in the coming months and years.”
When asked whether the industry would get a heads up when MUM goes live in search, Google Browse Liaison Danny Sullivan stated yes.
Screenshot from Buy Twitter Verification, June 2022 The Evidence For MUM As A Ranking Aspect When RankBrain rolled out, it wasn’t revealed till six months later. And a lot of updates aren’t announced or confirmed at all. Nevertheless, Google has actually become better at sharing impactful updates before they take place. For example, BERT was first announced in November 2018, rolled out for English-language
queries in October 2019, and rolled out worldwide later on that year in December. We had even more time to get ready for the Page Experience signal and Core Web Vitals.
Google revealed them over a year prior to the eventual rollout in June 2021. Google has actually already said MUM is coming and will be a big deal.

To Improve Search Engine Result As promised, Google revealed brand-new and possible MUM applications publicly. In June 2021, Google described the very first application of MUM and how it improved search engine result for vaccine information.
“With MUM, we had the ability to determine over 800 variations of vaccine names in more than 50 languages in a matter of seconds. After confirming MUM’s findings, we used them to Google Search so that people might find timely, high-quality details about COVID-19 vaccines worldwide.”In September 2021, Google shared ways that it might use MUM in the future, consisting of new methods to browse with visuals and text– along with a revamped search page to
make it more natural and user-friendly. In February 2022, Google provided insight into how RankBrain, neural matching, BERT, and MUM result in information understanding. In this post, the following was noted:” While we’re still in the early days of using MUM’s capacity, we’ve currently used it to improve look for COVID-19 vaccine info, and we’ll offer more instinctive methods to browse utilizing a combination of both text and images in Google Lens in the coming months. These are really specialized applications– so MUM is not presently used to help rank and enhance the quality of search results page like RankBrain, neural matching and BERT systems do.”In March 2022, Google posted an update about how MUM applied to searches related to an individual crisis.”Now, using our latest AI design, MUM, we can immediately and more accurately find a wider series of personal crisis searches. MUM can much better comprehend the intent behind people’s concerns to find when a person is in need, which assists us more dependably show credible and actionable details at the correct time. We’ll begin utilizing MUM to make these enhancements in the coming weeks.”Later on in the post, Google continued describing how MUM might improve search engine result.” MUM can transfer knowledge throughout the 75 languages it’s trained on, which can assist us scale security defenses worldwide far more effectively. When we train one MUM model to perform a task– like classifying the nature of a question– it finds out to do it in all the languages it knows
. For example, we utilize AI to lower unhelpful and sometimes harmful spam pages in your search results page. In the coming months, we’ll utilize MUM to enhance the quality of our spam securities and broaden to languages where we have very little training information. We’ll also have the ability to much better find personal crisis inquiries all over the world, dealing with trusted regional partners to show actionable info in several more countries.
