SEO foundations
Search engines do three things before a page can rank for anything: they crawl it, index it, and then decide where it belongs relative to everything else that could answer the same query. If any one of those three steps fails, nothing else in this guide matters yet.
Crawling is Google sending automated bots to discover your pages, usually by following links from pages it already knows about, or from a sitemap you submit directly. Indexing is Google storing a processed version of that page in its database. Ranking is the ongoing, per-query decision about which indexed pages best answer a specific search.
Most SEO problems trace back to one of these three stages, not to some mysterious algorithm penalty. A page that never gets crawled cannot rank. A page that gets crawled but never indexed cannot rank. And a page that is indexed but poorly matched to search intent will rank for the wrong queries, or none at all.
What actually influences ranking
- Relevance: does the page's content genuinely match what the searcher is trying to accomplish?
- Technical health: can the page be crawled, loaded quickly, and rendered correctly on mobile?
- Authority: do other credible sources link to or mention this page or domain?
- Experience and trust: does the content show real, first-hand expertise, and can readers verify who wrote it?
