It helps Google better comprehend the nuances of conversational queries, leading to more accurate and relevant search results. BERT has a significant impact on featured snippets and long-tail keyword searches.
8. E-A-T (Expertise, Authoritativeness, Trustworthiness): While not a specific algorithm, E-A-T is a set of guidelines used by Google’s Quality Raters to assess the quality and credibility of web content. Websites with high levels of expertise, authoritativeness, and trustworthiness are more likely to rank higher in search results, particularly for topics that require expertise, such as health or finance.
9. Core Updates: Google regularly releases core updates that aim to improve search quality and relevance. These updates can impact rankings across a wide range of websites, often leading to fluctuations in search rankings. Webmasters need to monitor these updates and adapt their SEO strategies accordingly to maintain or improve their search visibility.
10. Local SEO: While not a single algorithm, local SEO involves optimizing websites for local search queries and geographical relevance. Google considers factors such as proximity, relevance, and prominence when delivering local search results. Optimizing for local SEO can help businesses attract nearby customers and improve visibility in local search results.

In conclusion, Google’s algorithms are dynamic and ever-evolving systems designed to provide users with the most relevant and high-quality search results. From the foundational PageRank algorithm to the latest advancements in AI-driven technologies like RankBrain and BERT, Google’s commitment to improving search quality and relevance is evident.
