Google introduced a new algorithm that they say speeds up retrieval, ranking and improves accuracy. The Multi Vector Retrieval Algorithm (MUVERA) can be used for search as well as YouTube, and will have an effect on the way content appears if implemented as the new algorithm on search.
What Google have said
Google’s current system uses a system called RankEmbed to embed the content on the SERP. Rank Embed is a model that is extremely useful for common queries but often falls short when users have long-tail queries (more detailed, longer questions). MUVERA is said to improve upon RankEmbed and as a multi-vector system, is much better at answering long-tail queries. The Google announcement had this to say about the new MUVERA system:
“Unlike single-vector embeddings, multi-vector models represent each data point with a set of embeddings and leverage more sophisticated similarity functions that can capture richer relationships between data points.”
While this multi-vector approach boosts accuracy and enables the retrieval of more relevant documents, it introduces substantial computational challenges. In particular, the increased number of embeddings and the complexity of multi-vector similarity scoring make retrieval significantly more expensive.
In ‘MUVERA: Multi-Vector Retrieval via Fixed Dimensional Encodings’, we introduce a novel multi-vector retrieval algorithm designed to bridge the efficiency gap between single- and multi-vector retrieval.
…This new approach allows us to leverage the highly optimised MIPS algorithms to retrieve an initial set of candidates that can then be re-ranked with the exact multi-vector similarity, thereby enabling efficient multi-vector retrieval without sacrificing accuracy.“
What does this mean for SEOs
Modern algorithms such as MUREVA are more sophisticated and can create more sophisticated leaps between queries and their intent. This means that targeting specific keywords that SEOs have previously been focused on might be a thing of the past, with content being focused more on the overall context and creating it with answering the intent of specific queries in mind.
