At Google I/O 2021, Google revealed a brand-new technology called MUM (Multitask Unified Model) that it will use internally to assist its ranking systems better understand language.
Because the statement, there has actually been much conversation about if or when MUM would end up being a ranking aspect.
What Is MUM?
Dubbed “a new AI milestone for understanding details,” MUM is created to make it simpler for Google to respond to intricate needs in search.
Google guarantees MUM will be 1,000 times more powerful than its NLP transfer discovering 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 develop a more thorough understanding of understanding and information.
According to Google, they could apply MUM to record summarization, concern answering, and category jobs such as sentiment analysis.
MUM is a considerable concern inside the Googleplex, so it must be on your radar.
The Claim: MUM As A Ranking Aspect
When Google first revealed the news about MUM, many who read it naturally questioned how it might affect search rankings (especially their own).
Google makes countless updates to its ranking algorithms each year, and while the vast 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 5 years by Google itself.
And sure enough, BERT impacted about 10% of search questions.
RankBrain, which presented in the spring of 2015, is another example of an algorithmic upgrade that significantly impacted the SERPs.
Now that Google is discussing MUM, it’s clear that SEO specialists and the customers they serve should remember.
Roger Montti just recently blogged about a patent he thinks might supply more insight into MUM’s inner operations. That makes for a fascinating read if you wish to peek at what might be under the hood.
In the meantime, let’s think about whether MUM is a ranking aspect.

The Evidence Against MUM As A Ranking Factor
In his May 2021 intro to MUM, Pandu Nayak, Google fellow and vice president of Browse, made it clear that MUM innovation isn’t yet in play:
“Today’s online search engine aren’t rather sophisticated adequate to answer the way a professional would. But with a new technology called Multitask Unified Design, or MUM, we’re getting closer to helping you with these types of intricate requirements. So in the future, you’ll require fewer searches to get things done.”
Then, the timeline offered when MUM-powered features and updates would go live became “in the coming months and years.”
When asked whether the market 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 Aspect When RankBrain rolled out, it wasn’t revealed until six months later. And the majority of updates aren’t announced or validated at all. However, Google has progressed at sharing impactful updates before they occur. For example, BERT was initially announced in November 2018, rolled out for English-language
inquiries in October 2019, and rolled out worldwide later on that year in December. We had even more time to prepare for the Page Experience signal and Core Web Vitals.
Google announced them over a year before the eventual rollout in June 2021. Google has already stated MUM is coming and will be a huge deal.

To Improve Search Results Page As promised, Google announced new and potential MUM applications publicly. In June 2021, Google explained the first application of MUM and how it improved search engine result for vaccine details.
“With MUM, we had the ability to recognize over 800 variations of vaccine names in more than 50 languages in a matter of seconds. After verifying MUM’s findings, we used them to Google Browse so that people could find prompt, 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 search with visuals and text– in addition to a redesigned search page to
make it more natural and intuitive. In February 2022, Google offered insight into how RankBrain, neural matching, BERT, and MUM lead to info understanding. In this post, the following was noted:” While we’re still in the early days of taking advantage of MUM’s capacity, we have actually already used it to enhance look for COVID-19 vaccine details, and we’ll provide more intuitive methods to browse utilizing a mix of both text and images in Google Lens in the coming months. These are extremely specialized applications– so MUM is not currently used to help rank and improve the quality of search results like RankBrain, neural matching and BERT systems do.”In March 2022, Google posted an update about how MUM used to searches associated with an individual crisis.”Now, utilizing our most current AI model, MUM, we can automatically and more precisely spot a wider range of individual crisis searches. MUM can better comprehend the intent behind people’s concerns to identify when an individual is in need, which helps us more reliably show trustworthy and actionable details at the right time. We’ll start using MUM to make these enhancements in the coming weeks.”Later in the post, Google continued describing how MUM could enhance search engine result.” MUM can move knowledge across the 75 languages it’s trained on, which can help us scale safety protections worldwide much more effectively. When we train one MUM design to perform a job– like classifying the nature of a query– it learns to do it in all the languages it knows
. For example, we utilize AI to minimize unhelpful and in some cases harmful spam pages in your search engine result. In the coming months, we’ll utilize MUM to enhance the quality of our spam defenses and expand to languages where we have really little training information. We’ll also be able to much better discover individual crisis inquiries all over the world, dealing with trusted regional partners to reveal actionable information in a number of more countries.
“Our Decision: MUM Could Be A Ranking Factor While Google doesn’t use
MUM as a search ranking signal yet, it most likely might in the future. In several posts about MUM on The Keyword blog site
