Although search engines use search algorithms, they belong to the study of information retrieval, not algorithmics. The appropriate search algorithm to use often depends on the data structure being searched, and may also include prior knowledge about the data. Search algorithms can be made faster or more efficient by specially constructed ...
Search engine indexing is the collecting, parsing, and storing of data to facilitate fast and accurate information retrieval.Index design incorporates interdisciplinary concepts from linguistics, cognitive psychology, mathematics, informatics, and computer science.
Search engines responded by developing more complex ranking algorithms, taking into account additional factors that were more difficult for webmasters to manipulate. [citation needed] Some search engines have also reached out to the SEO industry and are frequent sponsors and guests at SEO conferences, webchats, and seminars.
The algorithm is what the search engines use to determine the relevance of the information in the index to what the user is searching for. One of the elements that a search engine algorithm scans for is the frequency and location of keywords on a Web page. Those with higher frequency are typically considered more relevant.

The inverted index data structure is a central component of a typical search engine indexing algorithm. [5] A goal of a search engine implementation is to optimize the speed of the query: find the documents where word X occurs. [6]
Google search engine robots are programmed to use algorithms that understand and predict human behavior. The book, Race After Technology: Abolitionist Tools for the New Jim Code [ 158 ] by Ruha Benjamin talks about human bias as a behavior that the Google search engine can recognize.
The "Hummingbird" update was the first major update to Google's search algorithm since the 2010 "Caffeine" search architecture upgrade, but even that was limited primarily to improving the indexing of information rather than sorting through information. [3]
