GOOGLE’S SEARCH ENGINE ALGORITHMS

Since its inception, Google ’s goal has been to provide users with the most relevant website content based on search queries. To achieve this, Google has used
closely guarded algorithms to determine website rankings in its search engine result pages (SERPs). Search engine optimization (SEO) is the practice that has
developed to help a website achieve higher rankings in SERPs.

algorithm. This led Google to start issuing algorithm updates to protect the value of search results.

3. Hummingbird
Hummingbird was launched in late 2013. It helps Google understand the content quality of webpage so it can display more accurate search results to complex
queries. This algorithm utilizes natural language processing that focuses on synonyms and co-occurring terms rather than specific keywords. The Rank Brain

4. Possum

is based on address and affiliation, the searcher’s physical location is given importance, results vary based on slight keyword variations, and the local filter runs
independently from the organic filter.

Fred was launched in March 2017. This algorithm update was aimed at sites that violate Google ’s webmaster guidelines. It tackles low quality, ad –centered
