Crawling, Indexing, and Querying

Before a search engine can shoe your website in search results, it must first find it. Crawling is the automated process by which search engines collects and analyzes the content of a web page, including the links on other pages.

- Indexing

As a crawler finds and analyzes the data on a web page, it stores the results of its findings in an index. Indexed data includes a page’s URL, title, and other content.

- Querying

When someone enters a term into a search engine, the search engine compares the search term to the data stored in its index. The search engine then displays, as search results, a list of the sites in its index that most closely match the user’s search term.
