Here are some significant updates:
- September 2021 Core Update: Google rolled out a core algorithm update in September 2021, which focused on improving search results relevance, particularly for local searches.
- Passage-Based Indexing: In February 2021, Google introduced passage-based indexing, which allows the search engine to identify and rank relevant passages of a web page rather than just the overall page content.
- BERT Update: In late 2019, Google introduced the Bidirectional Encoder Representations from Transformers (BERT) update, which uses machine learning to better understand the context of search queries and provide more relevant search results.
- E-A-T Update: In 2018, Google introduced an algorithm update that focuses on Expertise, Authoritativeness, and Trustworthiness (E-A-T) of content. This update aims to prioritize high-quality content from trusted sources in search results.
- Mobile-First Indexing: In 2018, Google started using mobile-first indexing, which means that the mobile version of a website is now the primary version used for indexing and ranking.
These updates reflect Google’s continued efforts to provide more relevant and accurate search results for its users. It’s important for businesses and website owners to stay up-to-date with these changes to ensure that their websites remain optimized for search engine rankings.
