Search engine algorithm
Search Engine Algorithm is a set of rules that a search engine uses to rank listings in response to a search query (sometimes referred to as the ”secret sauce””).
Search engines will periodically send a crawler through the website to view all its data. Their programs analyze the data to value the site and fix whether or not, and how high or low pages on the site will appear on various searches. These algorithms can be very complicated (Google alone uses 106 different variables) and search engines closely guard their algorithms as trade secrets.
