In this update, Google made major corrections to its algorithm that. A Google update, such as Mobile Update or Phantom Update, is the term used to describe a change that affects the way the Google search engine calculates rankings. Google's search link, Danny Sullivan, confirmed via Twitter on September 29 that a kind of “smaller update” had occurred (but this wasn't an update to the broad-core algorithm). While this was a paid search update, it had important implications for CTR for both paid and organic results, especially for competitive keywords.
Most SEOs are taking a wait-and-see approach to the useful content update, but many of them are sure that their content is useful. Hummingbird has been compared to caffeine, and it appears to be an update to the core algorithm that could drive changes in semantic search and in the Knowledge Graph in the coming months. Google announced its Bidirectional Encoder Representations from Transformers (BERT) update, which affected 10% of searches. Google released what appeared to be a major update, with reports of widespread impacts across the SEO community.
SEO tracking tools and industry conversations indicated that there could have been some kind of Google update (yet to be confirmed) on this date. Google later confirmed a basic update, but didn't provide any specific data and Google or the SEO community named the update. Just over a year after the original mobile optimization update, Google released another ranking signal increase to benefit mobile-optimized sites in mobile search. Google's search link, Danny Sullivan, confirmed via Twitter the release of a global update to the broad-core algorithm.
On September 27 (Google's 20th anniversary), many members of the SEO community began to notice significant peaks and drops in traffic, indicating that some kind of update was in progress. The Hawk update slightly corrected the Possum update, making local companies that competed with others that were already ranked in the SERPs more likely to be seen in a relevant search query. Webmasters and web positioning tools detected slight volatility between August 19 and 20, with signs that it could have been another quality update from Google (not confirmed). SEO ranking tools detected lower volatility on July 9, possibly another quality update from Google (not confirmed).
