Search engines use automated bots called crawlers to scan the web, following links from known pages to discover new ones. They evaluate factors like content uniqueness, keyword relevance, and site structure to decide if a page is worth storing in their index. Pages with original, useful content and clear navigation are prioritized, while duplicate or spammy pages often get skipped. This process helps build a database that serves accurate search results.
