Crawling and indexing

Overview

Crawling and indexing are the two critical processes that enable search engines to provide quick and relevant search results. These processes are also key for digital marketing strategies because they determine how and when a website will appear in search engine results.

Crawling

Crawling is the process by which search engines like Google, Bing, and Yahoo discover updated content on the web, such as new sites or pages, changes to existing sites, and dead links. To perform this task, they use bots called crawlers or spiders. These bots follow links from page to page, gather information, and send it back to the search engine's servers.

Indexing

After crawling has taken place, the collected data is processed and included in a search index, a massive database stored across multiple machines. Indexing is the process of organizing and categorizing the information found during crawling into this database, making it quickly and easily retrievable. It's this search index that you query whenever you perform a search on a search engine.
