Algorithms and SEO
In SEO, an algorithm is simply a program that gathers information for search engines and classifies it based on how useful it is likely to be to searchers.All search engines use algorithms to determine what websites should show up on each page of search results.
An algorithm update ensures that search engines, such as Google, Yahoo and Bing, are consistently providing users with the best possible experience. When any of the major search engines discovers a way it can improve the results on the search engine results pages, or SERPs, they program an algorithm update.
Some major Google algorithm updates include Panda, Penguin and “Mobilegeddon.”Google programmed each of these updates to weed out websites that didn’t provide value to searchers.
