The process by which a search engine stores a page in its database after crawling it.
01What it is and how it works
When a crawler visits a URL, it fetches the HTML, follows internal links, and extracts text, images, and structured data. The engine then creates a searchable record and adds it to the index. The index is a massive lookup table that matches query terms to relevant pages. If a page is blocked by robots.txt or returns an error, it never reaches the index.
Indexation means a search engine has read a page and saved it so it can show up when people search.
02What to do about it
- Submit a sitemap in Google Search Console.
- Check that important pages return a 200 HTTP status.
- Remove
noindextags from pages you want searchable. - Fix broken internal links that prevent crawlers from reaching content.
03How it is measured or noticed
In Google Search Console the Coverage report shows URLs that are Indexed, Excluded, or Error. The “URL Inspection” tool lets you test a single page and see the last crawl date, any indexing issues, and the rendered HTML that Google saw. A sudden drop in indexed pages often signals a crawl or technical problem.
04Common mistakes
- Leaving
noindexon product pages that should rank. - Blocking CSS or JavaScript files needed for rendering.
- Relying on meta refresh redirects instead of 301 redirects.
- Submitting duplicate URLs without canonical tags.
05Limits
Indexation does not guarantee ranking; relevance, authority, and user signals still decide position. Pages with thin content or heavy duplication may be indexed but later de‑ranked. Indexation is also different from crawling—a page can be crawled many times without ever being indexed if it fails quality checks.
06Worked example
"After adding a new product page, I submitted the URL via Search Console. The tool showed ‘Indexed, not submitted in sitemap’ and the page appeared in SERPs within 24 hours."
07Frequently asked questions
How is indexation different from crawling?
No, indexation and crawling are separate steps; crawling is the process of discovering pages, while indexation is storing the discovered content in the search engine’s database. Only after a page is indexed can it appear in search results.
Should I request indexing for every new page I publish?
Usually, you let search engines discover pages naturally, but you can request indexing for important pages using tools like the URL Inspection report. Over‑requesting can waste crawl budget without adding value.
Who actually performs the indexation of a page?
It depends on the search engine; its automated systems process the fetched content and add it to the index without human intervention. The process runs continuously as part of the engine’s infrastructure.
Does indexation still matter for AI‑powered search?
Yes, even AI‑driven results rely on an indexed corpus, so if a page isn’t indexed, it won’t be considered in the model’s responses. Ensuring your content is indexed remains a fundamental SEO step.
What happens if a critical page isn’t indexed?
If a page isn’t indexed, it won’t appear in search results, which you’ll notice as a drop in organic traffic and missing impressions. Fixing crawl errors or submitting the URL can restore visibility.
How long does it take for a newly crawled page to become indexed?
Typically, a page can be indexed within a few hours to a couple of days, but the exact timing varies by site authority and crawl budget. You can monitor its status in the Coverage report while you wait.
08Asked out loud
The same term in the words somebody uses speaking to an assistant rather than typing into a box — written from the situation, which is why each one carries the situation it came from.
No, it’s likely because the page hasn’t been indexed yet. Check the Coverage report and request indexing if needed; once indexed, it will become searchable.
Yes, the page may not be indexed, which means it isn’t in the search engine’s database. Verify its status in Search Console and fix any crawl issues to get it indexed.
Usually, you can ensure indexing by submitting the URL through the URL Inspection tool and confirming there are no errors; after the engine processes it, the page will be added to the index.
