What is Search Engine Rank?

Search engine ranking means that the search engine sends out a program that can discover new web pages and crawl files on the Internet. This program is often called a spider or a robot. Search engine spiders start from web pages known in the database and access these web pages and crawl files just like a normal user's browser. After processing the search terms, the search engine sorting program starts to find all the pages containing the search terms from the index database, and calculates which pages should be ranked first according to the ranking algorithm, and then returns to the "Search" page in a certain format , And then the sorting process takes only a second or two to complete and return the search results the user wants.
