How do search engines work?

Search starts with discovery. Search engines use automated crawlers to find URLs through links, sitemaps, redirects, and other signals. A public page can exist without being indexed, so publishing alone does not guarantee visibility.

Crawling is the process of fetching and processing a URL. Indexing is the process of deciding whether and how that content should be stored. Serving is the later step where the search engine selects and orders results for a query.

Your job as a site owner is to make important content accessible, understandable, and useful. Pages should have stable URLs, crawlable links, meaningful titles and headings, and content that answers the user's need.

Search Console helps you inspect individual URLs and monitor indexing and search performance. Use it to diagnose real problems instead of guessing from rankings alone.

A useful mental model is: discover → crawl → understand → index → serve. SEO work becomes much easier once you know which stage you are actually trying to improve.
