What is Search Engine Index? – Definition
The search engine index is a constantly updated, huge database containing all the websites that the search engine knows about. The resources of the index are increased by search engine robots, which search the Internet to find and analyze individual pages.
Before a page is added to the index, crawlers carefully process its content and evaluate it for value.
How does it work?
After entering a query into the search engine, its algorithms select the most suitable pages from the index and display the search results. You should get familiar with the algorithms of a given search engine and its requirements and optimize the website on this basis.
