Google Algorithm Updates and Changes: A Complete History

  • INCEPTION:

Google algorithms are used to extract data from a search index and provide the best possible results for a search query instantly. It uses a combination of algorithms and numerous ranking factors along with language techniques to rank websites based on relevance in search engine results pages (SERPs). Every minute, an estimated 3.8 million queries are typed into Google, prompting its algorithms to spit out results (Grind, 2019)

However, the search engine sometimes releases large algorithmic updates that significantly affect search results in a similar manner.
