    How Search Engines Work

    To understand SEO, you must first understand how search engines like Google operate. The process involves three main steps:

    • Crawling: Search engines use bots (also called spiders) to scan the internet and discover new or updated content.
    • Indexing: The content discovered is stored and organized in a giant database (index).
    • Ranking: When a user enters a query, search engines evaluate and rank relevant pages based on over 200 factors, including relevance, quality, and user experience.

    SEO is about optimizing your site so that it is easily crawled, indexed, and ranked by search engines.
