At Google I/O 2021, Google announced a new technology called MUM (Multitask Unified Model) that it will use internally to help its ranking systems much better comprehend language.
Since the announcement, there has been much conversation about if or when MUM would become a ranking aspect.
What Is MUM?
Dubbed “a brand-new AI milestone for comprehending information,” MUM is developed to make it easier for Google to answer complicated needs in search.
Google guarantees MUM will be 1,000 times more powerful than its NLP transfer learning predecessor, BERT.
MUM uses a model called T5, the Text-To-Text Transfer Transformer, to reframe NLP jobs into a merged text-to-text format and establish a more comprehensive understanding of understanding and information.
According to Google, they could use MUM to record summarization, concern answering, and classification jobs such as sentiment analysis.
MUM is a considerable top priority inside the Googleplex, so it ought to be on your radar.
The Claim: MUM As A Ranking Element
When Google first exposed the news about MUM, numerous who read it naturally questioned how it might impact search rankings (specifically their own).
Google makes thousands of updates to its ranking algorithms each year, and while the huge majority go unnoticed, some are impactful.
BERT is one such example. It was rolled out worldwide in 2019 and hailed the most considerable 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 considerably affected the SERPs.
Now that Google is discussing MUM, it’s clear that SEO experts and the clients they serve should keep in mind.
Roger Montti recently discussed a patent he believes might offer more insight into MUM’s inner functions. That produces an interesting read if you want to peek at what might be under the hood.
For now, let’s consider whether MUM is a ranking factor.

The Proof Versus MUM As A Ranking Factor
In his May 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 rather advanced sufficient to answer the method an expert would. But with a new technology called Multitask Unified Design, or MUM, we’re getting closer to helping you with these types of complicated requirements. So in the future, you’ll need less searches to get things done.”
Then, the timeline provided for when MUM-powered functions 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 Liaison Danny Sullivan said yes.
Screenshot from Buy Twitter Verified, June 2022 The Proof For MUM As A Ranking Aspect When RankBrain rolled out, it wasn’t announced up until six months afterward. And a lot of updates aren’t revealed or verified at all. However, Google has become better at sharing impactful updates prior to they happen. For instance, BERT was initially revealed in November 2018, presented for English-language
questions 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 prior to the ultimate rollout in June 2021. Google has actually already stated MUM is coming and will be a big offer.

To Enhance Search Results As guaranteed, Google revealed new and possible MUM applications publicly. In June 2021, Google explained the very first application of MUM and how it enhanced search engine result for vaccine info.
“With MUM, we had the ability to determine over 800 variations of vaccine names in more than 50 languages immediately. After confirming MUM’s findings, we applied them to Google Browse so that individuals could discover timely, premium information about COVID-19 vaccines worldwide.”In September 2021, Google shared manner ins which it might utilize MUM in the future, consisting of brand-new methods to browse with visuals and text– along with a redesigned search page to
make it more natural and intuitive. In February 2022, Google used insight into how RankBrain, neural matching, BERT, and MUM cause details understanding. In this post, the following was noted:” While we’re still in the early days of using MUM’s capacity, we have actually already utilized it to enhance searches for COVID-19 vaccine details, and we’ll use more instinctive methods to search using a mix of both text and images in Google Lens in the coming months. These are very 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 published an update about how MUM applied to searches connected to an individual crisis.”Now, utilizing our most current AI design, MUM, we can instantly and more accurately detect a wider series of individual crisis searches. MUM can much better understand the intent behind people’s questions to detect when an individual is in need, which assists us more reliably show reliable and actionable information at the right time. We’ll begin utilizing MUM to make these enhancements in the coming weeks.”Later on in the post, Google continued explaining how MUM could improve search engine result.” MUM can transfer knowledge across the 75 languages it’s trained on, which can help us scale safety protections worldwide much more efficiently. When we train one MUM design to carry out a task– like categorizing the nature of a question– it discovers to do it in all the languages it understands
. For example, we use AI to minimize unhelpful and in some cases unsafe spam pages in your search results. In the coming months, we’ll use MUM to enhance the quality of our spam protections and expand to languages where we have very little training data. We’ll likewise have the ability to better detect personal crisis queries all over the world, dealing with trusted regional partners to show actionable details in a number of more countries.
“Our Decision: MUM Could Be A Ranking Element While Google doesn’t utilize
MUM as a search ranking signal yet, it most likely might in the future. In numerous posts about MUM on The Keyword blog
