2023 E-E-A-T Knowledge Graph Update

In the extensive 2023 E-E-A-T Knowledge Graph update, Google made significant changes that have far-reaching implications for SEO and content optimization. This update, known informally as the "Killer Whale," began in July 2023 and had a cascading effect on subsequent core updates, possibly including the one in October 2023.

Key takeaways of 2023 E-E-A-T Knowledge Graph update:

1. Focus on Person Entities: The update primarily concentrated on enriching Google's Knowledge Vault with Person entities. Person entities tripled in just four days during the July 2023 update. By September 2023, there was a nearly 20-fold increase in the number of Person entities compared to May 2020.

2. Subtitles for People: Google's attention also shifted towards subtitles for people. The search engine made substantial changes to these subtitles, with a specific focus on roles that could be associated with E-E-A-T (Expertise, Authoritativeness, Trustworthiness) signals. For instance, individuals with titles like "Writer" or "Author" saw a 21% increase, emphasizing the importance of experts in various fields.

3. Reduced Reliance on Traditional Knowledge Sources: Google has significantly reduced its dependence on manually curated, structured third-party sources, such as IMDB, MusicBrainz, and government sites. This indicates that Google relies more on semantic relationships and algorithms to curate factual information.

4. Reduced Reliance on Wikipedia: The update also revealed a substantial decrease in Google's reliance on Wikipedia for Person entities. While Wikipedia triggered 40.9% of Person entities in June 2023, this dropped to just 12.44% in September 2023.

5. Three Major Takeaways: The key implications of this update are threefold: Google is accelerating the growth of its Knowledge Vault, particularly with a focus on Person entities. It's restructuring the Knowledge Vault to prioritize subtitles that enhance user trust and the application of E-E-A-T signals. Lastly, Google is beginning to decrease its dependence on Wikipedia and other human-curated sources for information.

6. Future Focus on Corporation Entities: Google will likely follow a similar path in reducing its reliance on Wikipedia for Corporation entities in the near future. SEO strategies that build Knowledge Graphs based on Wikipedia should consider transitioning to more organic approaches.

In summary, the 2023 E-E-A-T Knowledge Graph update represents a significant shift in Google's approach to structuring and curating information, focusing on Person entities, subtitles, and a reduced reliance on traditional sources like Wikipedia. SEO experts should adapt their strategies to align with these changes and anticipate further shifts in the future.
