What is Google MUM Update and its Expected Impact on SEO Optimized websites?


Rajiv Patil

It is said that Mum always knows best, but can Google's MUM update be said to be the same? Google, the world's largest search engine, has released its latest version as the solution we've been seeking to improve internet searching more straightforward and inclusive. Now, it is also an undeniable fact that google MUM will affect the SEO, but a technical SEO services company would always be prepared with enough expertise to deal with technologies.

After Hummingbird, Rankbrain, and BERT, MUM marks the next big paradigm leap for Google search. Unlike previous machine learning innovations, which used multiple skillful models for different tasks, MUM's goal would be to use only one model for all indexing, information retrieval, and ranking tasks.

What is the Google MUM update?

Google MUM (Multitask Unified Model) is a brand-new technology from Google. that uses machine learning to answer complex queries with no obvious answers. Although it was only introduced a few weeks ago, it has already generated a stir in the SEO world.

Google MUM is a query-answering system that understands and generates 75 different languages. Unlike BERT, it is capable of completing numerous jobs at the same time while gaining a thorough understanding of data. MUM is also multimodal, which means it can read information from both text and images, plus audio and video files are likely to be added to the list of modalities in the future.

This will result in consumers getting in-depth knowledge without exerting too much effort. It can aggregate and provide results that provide a systematic and integrated search experience, due to its capacity to work in nearly 75 languages. Even the most difficult queries can be answered by the algorithm.

It is unknown if the search engine employs this algorithm, if so, when it will be introduced and how it will affect SERP rankings. Google MUM update is built on the same transformer architecture as BERT, but it's much easier to get detailed answers to difficult questions here.

How does MUM work?

Google introduced MUM in May 2021 as a 1000-fold more powerful version of BERT. Natural language processing underpins both technologies. MUM, on the other hand, is about a lot far more than natural language processing.

MUM integrates many technologies to improve the user experience by making Google searches more semantic and context-based. MUM is Google's attempt to respond to complex search questions for which a standard SERP snippet is insufficient.

How can Google MUM affect SEO?


SEO specialists must adapt as a search engine's algorithms change. BERT had no visible influence on website performance when it was initially introduced a few years ago. When formulating a search query in simple, natural language, the advent of super-powerful AI will have an impact on it, and sites must answer in the same way. Let's look at how the Google MUM affects SEO.

  1. Eliminating language barriers

    Language becomes a hurdle for many consumers when it comes to websites that aren't multilingually optimized, for example. In this case, the algorithm may overcome these obstacles. Even if you typed a search word in a different language, it can research resources written in 75 languages and find relevant information on them.

    Let's imagine you're interested in learning more about Mt. Fuji. results are returned by the search engine, but they are in Japanese, which you are unaccustomed to. MUM will translate the content of these websites into your preferred language, allowing for longer responses.

  2. Simultaneously understanding multiple tasks

    This strategy will help you better understand the question; The mountains of Adams and Fuji are the two most prominent mountains in the world. Assume you've already completed the first and are looking for information on how to do the second in the fall. In that case, the algorithm might look at geological differences without considering fauna and flora.

  3. Language generation

    GPT-3? Have you heard of it? It's a human-like text generator that converts languages. The quality of it is so great that researchers are concerned that it will be difficult to discern from the real thing. When compared to MUM, the latter has a higher possibility of generating quality leads.

    To begin, it's important to understand the link between linguistic symbols' shape and their actual representation. The shapes of characters can be "understood" by a computer model, but not their meaning. With each development, the company tries to decrease prejudice in search and lessen its carbon footprint.

  4. Multimodality

    When contrasted to the GPT-3 and LaMDA, MUM technology has a significant advantage. The fact is that the system can grasp the information in multiple formats: for instance, photographs, videos, and text

Google MUM updated features every SEO should be aware off

MUM does not necessitate a significant change in your SEO strategy. However, it does place a greater emphasis on some of the more recent SEO features, such as entities and advanced content markup. You must be aware of these-

  1. Don't give up on classic SEO

    Complicated algorithms, for example, necessitate a significant amount of computing power. Yes, Google can now examine your pages in greater depth, but it still doesn't have the capacity to evaluate each page on the internet.

    So, Google's algorithm pre-selects pages on the basis of relevance, authority, and quality. After which it uses MUM to pull off the content from the pages. With entities, backlinks, and user experience, you must establish subject relevance, authority, and quality.

  2. Choose keywords over entities

    The total number of times a specific keyword is duplicated on a page used to be utilized by Google to determine page relevancy. The more times the keyword appears on the page, the more relevant it is. It's more than simply keywords when it comes to establishing entities. It's a mixture of using the correct words (in moderation), constructing links (not simply backlinks), and incorporating proper markup.

  3. Make use of every type of markup that is accessible.

    You must play ball and assist Google in finding this relevant information on your pages if you want to engage in SERP. Using correct markup in your text is the most obvious approach to do this.

    • YouTube metadata is what allows Google to analyze and break down your videos into smaller chunks.
    • Rich snippets appear in SERPs when you use schema markup, and it highlights key content on your pages.
    • HTML tags are used to emphasize essential parts of your page's text as well as to describe images.

How are Google MUM and Google BERT updates interrelated?

The invention of a natural language model called BERT by Google researchers shocked the natural language community in 2018. (Bidirectional Encoder Representations from Transformers). BERT received training in a novel and unusual manner. Rather than merely feeding the neural network text examples that were labeled with their meanings, Google researchers began by feeding BERT massive amounts of unannotated text.

The researchers masked specific terms in the text at random and challenged the model to fill in the blanks. The researchers masked specific terms in the text at random and challenged the model to fill in the blanks. MUM, according to Google, is more powerful than BERT. MUM was trained using data pulled from the open web, with low-quality information deleted, according to Google.


The Google MUM model was announced at the company's annual developer conference. The fascinating topic has turned into a revolution in the world of search engines. Multilingualism, multitasking, and multimodality are its strengths, all of which operate at the level of the human brain. Now you can see not only the shape of the symbols but also their context. So, how will this affect SEO if Google can read, hear, and see content in 75 languages before repackaging it in a new manner and in a language that the user understands?
