At Google I/O 2021, Google revealed a brand-new innovation called MUM (Multitask Unified Design) that it will use internally to assist its ranking systems better understand language.
Because the announcement, there has been much discussion about if or when MUM would become a ranking factor.
What Is MUM?
Dubbed “a brand-new AI turning point for understanding details,” MUM is created to make it easier for Google to respond to complicated needs in search.
Google assures MUM will be 1,000 times more powerful than its NLP transfer finding out 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 understanding and details.
According to Google, they might apply MUM to document summarization, concern answering, and classification jobs such as belief analysis.
MUM is a substantial top priority inside the Googleplex, so it should be on your radar.
The Claim: MUM As A Ranking Factor
When Google initially exposed the news about MUM, many who read it naturally questioned how it might impact search rankings (particularly their own).
Google makes countless updates to its ranking algorithms each year, and while the huge bulk go unnoticed, some are impactful.
BERT is one such example. It was rolled out worldwide in 2019 and hailed the most considerable 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 update that substantially affected the SERPs.
Now that Google is talking about MUM, it’s clear that SEO professionals and the customers they serve must take note.
Roger Montti recently blogged about a patent he believes might supply more insight into MUM’s inner workings. That makes for a fascinating read if you want to peek at what may be under the hood.
For now, let’s consider 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 technology isn’t yet in play:
“Today’s search engines aren’t quite advanced sufficient to address the way an expert would. But with a new technology called Multitask Unified Model, or MUM, we’re getting closer to assisting you with these kinds of complicated requirements. So in the future, you’ll require fewer 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 Search Liaison Danny Sullivan stated yes.
Screenshot from Buy Twitter Verified, June 2022 The Evidence For MUM As A Ranking Factor When RankBrain presented, it wasn’t announced till 6 months afterward. And many updates aren’t revealed or validated at all. Nevertheless, Google has actually become better at sharing impactful updates prior to they occur. For instance, BERT was initially announced in November 2018, presented 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 prior to the ultimate rollout in June 2021. Google has actually currently stated MUM is coming and will be a big offer.

To Enhance Search Engine Result As guaranteed, Google revealed new and possible MUM applications publicly. In June 2021, Google explained the very first application of MUM and how it improved search engine result for vaccine details.
“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 prompt, high-quality info about COVID-19 vaccines worldwide.”In September 2021, Google shared ways that it might utilize MUM in the future, consisting of brand-new methods to search with visuals and text– as well as an upgraded search page to
make it more natural and intuitive. In February 2022, Google provided insight into how RankBrain, neural matching, BERT, and MUM result in information understanding. In this post, the following was kept in mind:” While we’re still in the early days of taking advantage of MUM’s capacity, we’ve already utilized it to improve searches for COVID-19 vaccine information, and we’ll provide more intuitive methods to search utilizing a combination of both text and images in Google Lens in the coming months. These are really specialized applications– so MUM is not currently used to help rank and improve the quality of search results page like RankBrain, neural matching and BERT systems do.”In March 2022, Google published an update about how MUM used to searches connected to an individual crisis.”Now, utilizing our newest AI model, MUM, we can instantly and more properly discover a larger series of individual crisis searches. MUM can much better understand the intent behind individuals’s questions to find when an individual is in need, which helps us more reliably show credible and actionable information at the correct time. We’ll begin utilizing MUM to make these enhancements in the coming weeks.”Later on in the post, Google continued explaining how MUM might improve search engine result.” MUM can move understanding across the 75 languages it’s trained on, which can help us scale safety defenses worldwide a lot more effectively. When we train one MUM model to perform a job– like classifying the nature of a query– it finds out to do it in all the languages it knows
. For example, we use AI to reduce unhelpful and in some cases hazardous spam pages in your search results. In the coming months, we’ll utilize MUM to improve the quality of our spam protections and expand to languages where we have extremely little training information. We’ll also be able to better detect personal crisis queries all over the world, working with relied on regional partners to reveal actionable details in several more nations.
“Our Verdict: MUM Might Be A Ranking Aspect While Google doesn’t utilize
MUM as a search ranking signal yet, it probably could in the future. In several posts about MUM on The Keyword blog
, Nayak assures MUM will go through the exact same extensive testing processes as BERT prior to Google executes it into search. Featured Image: Paulo Bobita/Best SMM Panel
