Conclusion: Even though EEAT is probably more relevant for websites in certain categories, it would be advisable to study EEAT in depth. It is one of the key concepts for fully understanding Google Core Updates.
EEAT and the impact of Google core updates
Several times a year, Google implements significant and far-reaching modifications to its search algorithms and search systems. These changes are known as fundamental updates and are reflected in Google search ranking updates.
The goal of these fundamental updates is to provide Google Search users with reliable and useful answers to their search queries. See " Google Search Central Updates " for more information.
Most of these core updates have significant impacts on a wide range of websites. The focus of these "core updates" is not on individual pages, but rather on the overall evaluation of content by the Google algorithm.
Key aspects to consider in connection with the Google Core Updates include:
understanding user intentions,
the relevance of your content,
the quality of your website (page experience / mobile optimization)
and the EEAT principle (Expertise, Authority, Trustworthiness).
In summary: Core updates are modifications that Google typically makes two to three times a year and can often lead to significant changes in the visibility of your website.
