Adjust and adapt to maintain or improveBeing aware of the history of Google’s algorithm updates can help explain changes in organic search results rankings. With this knowledge, you can adjust your optimization strategies to adapt to the changes Google makes, in an effort to maintain or improve your organic page ranking.
Better, cleaner, fasterFrom the beginning, Google’s goal has always been to deliver the most relevant and quality results to users. As Google's co-founder Larry Page puts it, “The perfect search engine would understand exactly what you mean and give back exactly what you want.” Right from the inception of Google as a search engine in 1998, however, spammy content and web link spam have been a widespread common occurrence which reached its peak in 2011. Although Google had been reindexing the whole web almost every month, to better combat spam they began to introduce major updates to their algorithm which delivered serious changes to the Search Engine Results Pages (SERP). With every major update introduced, parts of Google's code had been rewritten or replaced with better abstractions to make search criteria more robust, cleaner, and faster.
