MUM (Multitask Unified Model)

MUM (Multitask Unified Model), introduced by Google in 2021, is an incredibly powerful, AI-driven natural language processing model that is 1,000 times more powerful than BERT. MUM is designed to understand complex, multi-faceted search queries that previously required a user to perform multiple separate searches. Furthermore, MUM is multimodal; it can simultaneously understand text, images, audio, and video across 75 different languages. While MUM is not a direct ranking signal you can optimize for with keywords, it fundamentally shifted SEO toward the necessity of publishing deeply comprehensive, multimedia-rich content that answers complex, nuanced questions.

MUM is a massive, incredibly smart AI that Google uses to understand really complicated questions. It can read text, look at pictures, and translate 75 languages all at once to give you the perfect answer, meaning websites have to write much more detailed, helpful articles to rank.
