How Search Engines Work: Understanding Google, Bing, and AI Search

Understanding how search engines work is the foundation of effective SEO. Google, Bing, and AI-powered search engines like ChatGPT and Perplexity all discover, process, and rank content differently.

These guides explain the mechanics: how crawlers discover pages, how indexing works, how ranking algorithms evaluate content, and how the emergence of AI search engines is changing the landscape.

Key Takeaways

  • Search engines work in three stages: crawling (discovery), indexing (understanding), and ranking (serving results)
  • Google and Bing use fundamentally different ranking approaches - optimising for one doesn't guarantee results on the other
  • AI search engines synthesise information rather than listing links - they reward authoritative, well-structured content
  • Understanding search engine mechanics helps you diagnose why pages aren't ranking
