How does Search Engine Actually Work?

A search engine is a program that uses keywords or phrases to assist users to discover the information they’re looking for on the internet. By continuously monitoring the Internet and indexing every page they encounter, search engines are able to deliver results quickly even with millions of websites online.

Using their own web crawlers, search engines crawl hundreds of billions of pages. Search engine bots or spiders are frequent names for these web crawlers. A search engine navigates the internet by downloading web pages and following links on those sites to find new pages that have been added. When a user types in a search phrase, the search engine examines the website page titles, contents, and keywords it has indexed, then employs algorithms (step-by-step procedures) to generate a list of websites, with the most relevant sites at the top. When a user conducts a search, search engines explore its index for highly relevant content, which is then ordered in the hopes of answering the searcher’s question. The ranking is the process of sorting search results by relevance. In general, the higher a website’s ranking, the more relevant the search engine considers the site to be to the query.

The goal of the search engine algorithm is to give a relevant set of high-quality search results that will rapidly answer the user’s query. The user then chooses an option from the list of search results, and this action, together with the following activity, contributes to future learnings that may affect future search engine rankings. Understanding how search engines operate is the first step toward improving your Google ranking and increasing your traffic. You’re already dead in the water if search engines can’t find, crawl, and index your sites.
