Indexing

Q: What does indexing mean in SEO?

Indexing is the process by which Google takes a crawled URL into its search index. Only indexed pages can appear in search results. Not every crawled URL is indexed — Google filters out low-quality pages, duplicates and noindex pages.

Q: How do I check whether a page is indexed?

There are two routes: (1) URL inspection in Google Search Console (authoritative), (2) a site search site:example.com/my-page (a quick check, less precise). GSC additionally shows the indexing status and the reasons for exclusion.

Q: Why is my page not being indexed?

The most common reasons: (1) a noindex tag in the HTML or HTTP header, (2) a robots.txt block, (3) duplicate content with a different canonical, (4) a low-quality assessment (thin content, AI generation without editorial work), (5) missing internal linking, (6) a new domain without trust signals.

Q: How do I speed up indexing?

Through four signals: (1) submit the URL in GSC via ”Inspect URL → Request indexing", (2) update the XML sitemap, (3) strong internal linking from top pages, (4) external backlinks from trusted sources. For news sites, a news sitemap additionally allows indexing within seconds.

Also known as: Indexing, Indexation, Inclusion in the index

Indexing is the process by which a search engine takes a crawled URL into its search index — the database from which search results are drawn. A URL must first be crawled, then rendered and finally indexed before it can appear for a search query at all. As the web has grown (2026 estimate: around 1.5 billion websites), Google long ago stopped indexing every URL it finds automatically — selective indexing is the rule today.

The four indexing states in Search Console

Indexed — the URL is in the index and can rank.
Crawled, currently not indexed — Google has seen the page but decided against including it. Usually a quality problem, a duplicate or weak content.
Discovered, currently not crawled — the URL is known to Google (for example from an internal link) but has not yet been looked at. A crawl budget problem.
Excluded — deliberately excluded via noindex, canonical, robots.txt or a 4xx status.

What increases the likelihood of indexing

High content quality — the main factor since the Helpful Content System in 2022.
Internal linking — make new URLs reachable from the top navigation path rather than burying them five clicks deep.
Sitemap.xml — new URLs belong in the sitemap, which is updated regularly.
Backlinks — external links speed up crawling and indexing.
Fast loading time — well-performing pages are indexed preferentially.
Clean technical status — 200 OK, no noindex, no accidental robots.txt disallow.

Diagnosing indexing problems

Workflow for URLs that are not indexed: (1) URL inspection in GSC — what does Google say? (2) Live test in GSC — is the page crawled and rendered now? (3) Manual check of the three killers: noindex meta tag, canonical pointing to another URL, robots.txt disallow. (4) Content check: does the page provide value of its own, or is it thin/duplicate? (5) For structural problems: submit a manual indexing request in GSC (inspect URL → ”Request indexing").

Example from practice

Example: A shop launches 240 new product pages. After six weeks only 87 are indexed. The GSC diagnosis shows that 110 are ”Crawled, currently not indexed" — the product texts have been copied one to one from the manufacturer's data sheet (duplicate content), images have no ALT text, and there are no reviews. After rewriting the descriptions with the shop's own use-case explanations and adding user reviews and an FAQ to each page, a further 89 are indexed within four weeks — and the shop's organic traffic doubles.
