At Google I/O 2021, Google announced a new technology called MUM (Multitask Unified Design) that it will use internally to help its ranking systems better comprehend language.
Given that the announcement, there has actually been much discussion about if or when MUM would become a ranking aspect.
What Is MUM?
Called “a brand-new AI milestone for understanding details,” MUM is designed to make it easier for Google to address complicated needs in search.
Google guarantees MUM will be 1,000 times more powerful than its NLP transfer learning predecessor, BERT.
MUM uses a design called T5, the Text-To-Text Transfer Transformer, to reframe NLP tasks into an unified text-to-text format and establish a more detailed understanding of knowledge and details.
According to Google, they might apply MUM to record summarization, question answering, and category jobs such as sentiment analysis.
MUM is a substantial top priority inside the Googleplex, so it should be on your radar.

Google makes thousands of updates to its ranking algorithms each year, and while the large bulk go unnoticed, some are impactful.
BERT is one such example. It was presented worldwide in 2019 and hailed the most considerable update in 5 years by Google itself.
And sure enough, BERT affected about 10% of search queries.
RankBrain, which presented in the spring of 2015, is another example of an algorithmic upgrade that significantly affected the SERPs.
Now that Google is talking about MUM, it’s clear that SEO professionals and the clients they serve should take note.
Roger Montti recently wrote about a patent he believes might provide more insight into MUM’s inner workings. That produces an intriguing read if you want to peek at what might be under the hood.
For now, let’s consider whether MUM is a ranking aspect.

The Proof Against MUM As A Ranking Element
In his Might 2021 intro to MUM, Pandu Nayak, Google fellow and vice president of Search, made it clear that MUM technology isn’t yet in play:
“Today’s online search engine aren’t quite advanced enough to respond to the way a specialist would. But with a brand-new technology called Multitask Unified Design, or MUM, we’re getting closer to assisting you with these kinds of complicated requirements. So in the future, you’ll require less searches to get things done.”
Then, the timeline provided for when MUM-powered features and updates would go live ended up being “in the coming months and years.”
When asked whether the industry would get a heads up when MUM goes live in search, Google Browse Intermediary Danny Sullivan said yes.
Screenshot from Buy Twitter Verification, June 2022 The Proof For MUM As A Ranking Factor When RankBrain presented, it wasn’t announced up until 6 months later. And the majority of updates aren’t revealed or verified at all. Nevertheless, Google has actually progressed at sharing impactful updates before they occur. For example, BERT was initially revealed in November 2018, presented for English-language
questions in October 2019, and presented worldwide later that year in December. We had much more time to prepare for the Page Experience signal and Core Web Vitals.
Google announced them over a year prior to the eventual rollout in June 2021. Google has actually currently said MUM is coming and will be a huge offer.

To Enhance Search Engine Result As promised, Google announced new and potential MUM applications openly. In June 2021, Google described the first application of MUM and how it improved search results page for vaccine info.
“With MUM, we were able to recognize over 800 variations of vaccine names in more than 50 languages immediately. After validating MUM’s findings, we applied them to Google Search so that individuals might discover timely, high-quality information 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 an upgraded search page to
make it more natural and intuitive. In February 2022, Google used 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 tapping into MUM’s potential, we’ve currently used it to improve searches for COVID-19 vaccine information, and we’ll use more instinctive ways to search using a combination of both text and images in Google Lens in the coming months. These are very specialized applications– so MUM is not currently used to assist rank and improve the quality of search engine result like RankBrain, neural matching and BERT systems do.”In March 2022, Google posted an update about how MUM used to searches related to a personal crisis.”Now, using our most current AI design, MUM, we can immediately and more precisely detect a broader series of personal crisis searches. MUM can much better understand the intent behind people’s questions to spot when a person remains in need, which assists us more dependably reveal reliable and actionable information at the correct time. We’ll start utilizing MUM to make these enhancements in the coming weeks.”Later on in the post, Google continued describing how MUM might enhance search results page.” MUM can transfer understanding throughout the 75 languages it’s trained on, which can assist us scale security securities worldwide far more efficiently. When we train one MUM model to perform a task– like categorizing the nature of an inquiry– it finds out to do it in all the languages it knows
. For example, we use AI to minimize unhelpful and in some cases harmful spam pages in your search engine result. In the coming months, we’ll use MUM to improve the quality of our spam protections and broaden to languages where we have very little training information. We’ll also have the ability to much better find individual crisis questions all over the world, dealing with trusted regional partners to reveal actionable details in numerous more nations.
“Our Verdict: MUM Might Be A Ranking Aspect While Google does not utilize
MUM as a search ranking signal yet, it most likely might in the future. In numerous posts about MUM on The Keyword blog site
