How Google indexing works
Google indexing is the process by which Google discovers your pages, crawls them, and adds them to its index so they can appear in search results. Discovery happens through links, sitemaps, and prior knowledge. Crawling is when Googlebot requests your pages and respects robots.txt and crawl directives. Indexing is when Google processes the content and decides whether to include it. Understanding this flow helps you fix issues when pages don't appear in search.
Discovery and crawl
Google finds new or updated URLs through links from other pages, XML sitemaps you submit, and URLs it has seen before. Crawl budget and priority depend on site size, quality, and how often content changes. You can help by submitting a sitemap, using internal links, and avoiding blocks in robots.txt or noindex unless you have a reason.
- Submit an XML sitemap in Search Console
- Link to important pages from the homepage or hubs
- Avoid blocking Googlebot in robots.txt for content you want indexed
What happens after crawl
After fetching a page, Google parses the content and may render JavaScript. It evaluates quality, relevance, and indexability. Pages that meet the guidelines can be added to the index. Duplicate or low-quality content may be indexed with a canonical or not indexed at all. You can use URL Inspection to see the status and request indexing for important URLs.
- Check index status in Search Console URL Inspection
- Fix noindex or canonical issues if you want the page indexed
- Allow time for re-crawl after making changes
