How Search Engines Work

After discovering the pages, they proceed to indexing, where Google gathers the content of each page, its structure, as well as its intent, and stores the data in its enormous database.
Ranking is the last process, and here Google decides which pages to display at the top of those that have been searched. The ranking is done according to various factors, which include relevancy, freshness, quality of content, use of keywords, backlinks, security, and user experience. The algorithms used in Google consider these factors in order to deliver the best and most useful results to the user. Knowing the functioning of the search engines can enable small businesses to optimize their websites so as to have a better chance of making it on the first page.
