# Why your website needs Bing to appear in ChatGPT, and how IndexNow gets it there in minutes

**ChatGPT's web search runs on Bing's index, with OpenAI's own crawler layered on top.** A website Bing has never indexed cannot be cited in a ChatGPT search answer, however well it ranks on Google. Verifying the site in Bing Webmaster Tools, submitting a sitemap and wiring IndexNow gets new and changed pages to Bing in minutes rather than weeks, and Bing's AI Performance report is the only vendor dashboard that shows when an assistant actually cited you.

## Where does ChatGPT get its search results?

OpenAI's [publishers and developers FAQ](https://help.openai.com/en/articles/12627856-publishers-and-developers-faq) states that "any public website can
appear in ChatGPT search," provided its search crawler is not blocked, and its
[crawler documentation](https://developers.openai.com/api/docs/bots) adds that sites opted out of OAI-SearchBot "will not be
shown in ChatGPT search answers." Underneath that crawler sits Bing's index. Most Canadian small
businesses have never verified their site with Bing, never submitted a sitemap to it, and have no idea
whether it has crawled them. On Google they may be fine. In the index the assistant reads, they may be
absent.

## Why does Bing Webmaster Tools matter more than Bing's market share?

Three reasons, all documented. First, Bing's [Webmaster Guidelines](https://www.bing.com/webmasters/help/webmaster-guidelines-30fba23a) now
describe how it "discovers, crawls, indexes, evaluates, and surfaces content across Bing search
experiences, Copilot, and grounding API results." It is the one search engine that states in writing what
makes a page eligible to be cited by an assistant. Second, verifying the site is how you submit a sitemap
and see what Bing has actually indexed. Third, in February 2026 Bing shipped an
[AI Performance report](https://blogs.bing.com/webmaster/February-2026/Introducing-AI-Performance-in-Bing-Webmaster-Tools-Public-Preview) inside Webmaster Tools that shows citation counts per
URL and the "grounding queries" Copilot generated to retrieve your content. Google offers no equivalent;
Google's own documentation says traffic from AI features is folded into the ordinary Web row of Search
Console with no separate line. If the question is "is an AI citing us," Bing is where the answer lives,
and it needs a verified site.

## What is IndexNow?

[IndexNow](https://www.indexnow.org/documentation) is a protocol for telling search engines a URL changed, instead of
waiting to be crawled. One request reaches every participating engine, because they "agree that submitted
URLs will be automatically shared with all other participating search engines." The
[current participant list](https://www.indexnow.org/searchengines.json) is Bing, Yandex, Seznam, Naver, Yep, the
Internet Archive and Amazonbot. Google does not participate; Google discovery stays sitemap plus Search
Console. For a site that wants to be citable by ChatGPT, IndexNow is the direct line to the index that
matters.

The mechanics are small. You host a key file at the root of the site, then send one request per
changed URL. Bing's guidelines ask that you do it that way rather than in bulk: "Avoid batch submissions
when possible. Streaming submissions provide faster updates, reduce server load, and improve indexing
accuracy."

| Response | Meaning |
| --- | --- |
| 200 | Accepted. |
| 202 | Accepted, key validation pending. Normal on a brand-new key; ping again later. |
| 400 | Bad request format. |
| 403 | Invalid key. |
| 422 | The URL does not belong to the host, or the key does not match. |
| 429 | Too many requests. Slow down. |

## What does this look like on a real site?

On this site every deploy submits the changed URLs automatically, so a page edited in the morning is
known to Bing before lunch, and the key file that authorises the submission sits at the root where the
protocol requires it. That is the whole setup: a key, a sitemap, a verified property, and a ping on
publish. A site that does none of those waits for Bing to find it, which can take weeks, and the
assistant reading Bing's index waits with it.

## What about Google?

Google's route is the sitemap and Search Console. Two facts from Google's
[sitemap documentation](https://developers.google.com/search/docs/crawling-indexing/sitemaps/build-sitemap) save a lot of wasted effort: Google "ignores the
priority and changefreq values" many tools still generate, and it uses the lastmod date only if it is
"consistently and verifiably accurate." A sitemap that stamps today's date on every page teaches Google to
ignore the field. Keep the dates honest and submit the file once; Google does the rest on its own
schedule.

## Where this fits

Getting into Bing's index is the third of three checks. The first is whether the crawlers can reach
and read the site at all, covered in
[can ChatGPT see my website](https://bluecraneworks.ca/articles/can-chatgpt-see-my-website). The second is whether a
forgotten directive is forbidding citation, covered in
[the two settings that hide a website from AI answers](https://bluecraneworks.ca/articles/noarchive-nosnippet-remove-your-site-from-ai-answers).
All three are done, verified and reported in the [AI Visibility Pass](https://bluecraneworks.ca/solutions/ai-visibility.html), and on a
[managed website](https://bluecraneworks.ca/solutions/websites.html) they are included from the day it launches. And the limit, in Bing's
own words, applies to all of it: "SEO does not guarantee rankings or traffic, and GEO does not guarantee
grounding or citations in AI experiences." Being in the index is the precondition, not the prize.
