Start by identifying which step is failing: the fix for a blocked crawler is different from the response to a page that is indexed but not cited.
First, identify what “missing” means
Record the exact product, query, page, language, country or region, and date where you expected your site to appear. Google AI Overviews and AI Mode are not interchangeable with ChatGPT Search or Bing, and a page’s presence can vary by query and product. Google says AI Overviews appear when its systems determine they add value, and links may differ between AI Overviews and AI Mode.
Separate four checks:
- Crawlable: the search crawler can request the page and access its content.
- Indexed: the search engine has included the page in its index, using the intended canonical URL where applicable.
- Eligible: the page meets the relevant product’s requirements to be considered. For Google AI Overviews and AI Mode, a page must be indexed and eligible to appear with a Search snippet to be eligible as a supporting link. Google’s AI features guidance also makes clear that meeting requirements does not guarantee crawling, indexing, or serving.
- Selected: the system chooses the page for this particular answer. Eligibility is not a promise of citation.
These distinctions matter because an indexed page that does not appear in one answer is not necessarily broken. Diagnose access and indexation first; then assess whether the page clearly answers the query.
Check whether crawlers can fetch the page
Look for barriers at both the site and infrastructure levels. A correct page-level setting cannot help if a firewall, CDN, authentication gate, redirect loop, or server error prevents the crawler from reaching the content.

- Review
robots.txtfor rules applying to the relevant crawler. - Check hosting, CDN, firewall, and server configuration for blocked or failed requests.
- Confirm the page returns the intended response and that important content is available as readable text, not only in a form a crawler may fail to access.
- For Google, permit crawling through both
robots.txtand the hosting infrastructure. Google lists these as considerations in its AI features guidance.
For ChatGPT Search, check OAI-SearchBot
OpenAI identifies OAI-SearchBot as the crawler used for search. If you want your site to be considered for ChatGPT Search, check that your robots rules and network controls do not block it. OpenAI says websites that opt out of OAI-SearchBot will not appear in ChatGPT search answers, although they may still appear as navigational links. OpenAI’s crawler overview distinguishes OAI-SearchBot from GPTBot, which has a separate stated purpose related to potential model training. Do not treat the two crawler settings as equivalent.
Find the specific indexation issue
For Google, inspect the exact page rather than inferring its status from the homepage or a broad site search.
Rank #2
- Open Google Search Console and use URL Inspection for the page’s URL.
- Review the reported indexing status and reason. Then use the Page indexing report to find related affected URLs and patterns. Google’s Page indexing report documentation describes the report and its status categories.
- Check whether Google selected the intended canonical URL, and whether the page is linked from relevant pages or included in a sitemap.
- Make changes that address the reported cause, then request validation or indexing as appropriate in Search Console.
Common explanations include a deliberate noindex directive or robots block, a duplicate or alternate URL, a redirect, or a page Google cannot discover through links or a sitemap. Not every URL should be indexed: removed, duplicate, alternate, or intentionally excluded pages may properly remain outside the index.
For Bing, its official “Why is My Site Not in the Index?” guidance identifies a robots.txt block as a possible cause and mentions rare removal for guideline violations or malware. Bing Webmaster Tools provides index-status and robots.txt testing features; use those to investigate Bing-specific visibility rather than assuming Google’s reports describe Bing’s index.
Rank #3
Use robots.txt and noindex for different purposes
robots.txt controls crawling; it is not a reliable way to keep a URL out of search results. A blocked URL may still appear based on links elsewhere, without a normal description. Google’s robots.txt guide explains this distinction.
- If the page should be public and discoverable: remove an unintended crawl block. Confirm that Google can fetch it and that the page does not carry an unintended
noindexdirective. - If the page should be excluded from Google Search: use an appropriate
noindexdirective or access control. Google must be able to crawl a page to read itsnoindex; blocking it inrobots.txtcan prevent Google from seeing that directive.
Before changing a site-wide rule, establish which URLs it affects. A broad robots change or removal of a noindex rule can expose pages you meant to keep out of search.
Rank #4
Make important pages easy to discover and understand
Once access and indexing are sound, improve the page’s findability and clarity using established SEO fundamentals:
- Link to important pages from relevant parts of the site using descriptive link text.
- Put the substantive answer in clear, readable page text so users and crawlers can identify what the page covers.
- Keep structured data consistent with the visible page content.
- Ensure the page’s topic and wording directly address the query for which you want it considered.
Google says current SEO fundamentals apply to AI Overviews and AI Mode, with no additional AI-specific technical requirements, special schema.org data, or machine-readable AI text files required for those features. That does not mean good site structure and useful content guarantee a supporting link. Do not treat llms.txt or FAQ schema as a proven shortcut to Google AI citations.
Measure changes without assuming every AI answer is trackable
Google includes AI Overviews and AI Mode appearances in the Search Console Performance report under Web search. Monitor relevant pages and queries there, and use your analytics to review referral behavior. Those reports do not establish that a site’s visibility across all AI search products can be observed in one place.
OpenAI says any public website can appear in ChatGPT Search, but being public is not a guarantee of appearing in a particular answer. Its publisher and developer FAQ provides platform-specific guidance. For Bing, use Bing Webmaster Tools for its index-status checks. Keep the product, query, region, and date with your observations so that a change in one answer is not mistaken for a universal visibility result.
Allow time for changes to be processed. Google says recrawling and processing a preview-control change can take from several days to several months. A request or corrected setting does not guarantee a particular search result or AI citation.
