Almost every SEO measurement tool focuses on Google AI Overviews and ChatGPT first, Perplexity second, Copilot a distant fourth. That ranking does not match where decision-makers actually live. Copilot is bundled into the operating system most enterprises run. It is the default search inside Edge. It is one tab away inside Outlook, Word, Excel, and Teams. The query volume is large and the buyer intent is unusually high.
The competitive density in Copilot is also lower than in any other major AI surface. Most domains have not invested in Bing-specific signals since the early 2010s. The result is that a competent Copilot push often shows citation lift inside three to four weeks — faster than ChatGPT and dramatically faster than Google AI Mode.
There is no separate 'Copilot bot.' Copilot pulls live answers from the Bing index, so the only crawler you need to allow is bingbot. The retrieval layer that selects citations runs on top of that index and is not directly observable in your logs. What you can observe is whether bingbot is hitting the URLs you want cited, and how recently each one was last crawled.
IndexNow is Microsoft's open protocol for instant URL submission. Ping the IndexNow endpoint when you publish or update a page, and Bing recrawls it within minutes (we routinely see crawl-to-citation latency under two hours). IndexNow is also adopted by Yandex and Naver, but the Bing implementation is the one that drives Copilot results.
Implementation is a single POST request per URL change. You generate a key file, place it at the root of your domain, and any time a page changes you fire an IndexNow notification. We ship this on every client site as part of the GEO foundation; the lift on Copilot citation share is large and immediate.
Copilot is unusually schema-hungry. Pages with rich Article, FAQPage, HowTo, Organization, and Product markup are dramatically more likely to be cited than identical pages without it. The retrieval layer uses the structured data both as a relevance signal and as the literal source of the answer string it shows the user.
Across roughly 60 client sites we have tracked Copilot citation behavior at scale, and four patterns dominate the citations we see:
Verifying in Bing Webmaster Tools is the equivalent of verifying in Google Search Console. You get crawl stats, index coverage, the Site Explorer, the URL inspection tool, and the IndexNow dashboard. You also get Microsoft Clarity integration if you want it. There is no free, lower-friction equivalent. Skipping this is the single most common mistake we see in Copilot audits.
Yes. Copilot's retrieval layer queries the Bing index directly, then re-ranks for citation suitability. If a URL is not in Bing, it cannot be cited in Copilot. Step one is always to confirm coverage in Bing Webmaster Tools.
We typically see bingbot fetch within 5–15 minutes of an IndexNow ping for established domains. New domains can take several hours on the first push. The first citation lift in Copilot usually appears within 24–48 hours of recrawl.
These are independent decisions. Bingbot is required for Copilot; GPTBot governs OpenAI training. Many publishers block GPTBot training but allow OAI-SearchBot for ChatGPT live retrieval and bingbot for Copilot. We cover the bot-by-bot tradeoffs in the AI Crawlers guide.
The signals overlap with classic Bing ranking (relevance, authority, freshness) but add weight to schema completeness, declarative answer structure, and entity strength. Pages that read like a Wikipedia article tend to outperform pages that read like a marketing landing page.
It uses the same web retrieval layer for public-internet sources, so optimizing for Copilot generally optimizes for the M365 'web grounding' layer too. The internal-document grounding (SharePoint, OneDrive) is a separate enterprise concern.
