Semrush Drops Copilot Tracking on Nov. 9, Bing Data Remains

You probably have a Copilot line in your AI visibility report. Check whether the tool behind it plans to keep collecting that number.

Semrush emailed Enterprise AIO customers that it will stop tracking Microsoft Copilot on November 9, 2026. Tracking for its other AI platforms continues. As PPC Land reproduced the notice, it blames "Recent changes to Microsoft Copilot's access requirements" that "prevent AI visibility platforms, including Semrush Enterprise AIO, from collecting the data needed to track Copilot performance."

My read is that this changes what you can measure, not how visible you are. Microsoft's own Bing Webmaster Tools AI Performance report is the Copilot data that stays, and I would save a copy before November 9.

Consultant Glenn Gabe made the notice public on X on October 29.

AI visibility tools are facing their own version of tracking issues. @Semrush just emailed customers yesterday that Copilot visibility tracking will be discontinued as of 11/9 based on how Microsoft is preventing the tracking of Copilot data. I wonder when other platforms will inform customers.

Gabe put it in stronger terms than Semrush did. The notice says the changes affect AI visibility platforms in general, with Semrush as one example, and it does not say when they took effect. Semrush did not name the Microsoft change it means. PPC Land points to Microsoft's Copilot Terms of Use, which took effect on August 18, 2026. They require a Microsoft account and list bots and scrapers as prohibited. Semrush has not said whether that is the change it means.

The notice also gives customers a choice. They can return their Copilot prompts to their balance, or keep the history while those prompts still count against it. Semrush's pricing page lists nine tracked AI platforms. Eight remain.

What the cutoff does to your numbers

Copilot is a small slice of AI traffic. Similarweb put it at 2.0 percent of worldwide generative AI website traffic in May 2026. Reporting takes the larger hit. A share of voice figure is only as complete as the list of platforms behind it. If your report blends Semrush's Copilot data with other engines, the platforms behind it change on November 9. Numbers before and after the cutoff stop being comparable. That is a change in measurement, not in visibility.

Microsoft does publish its own data. Bing Webmaster Tools AI Performance has been in public preview since February 10, 2026. It reports citations, cited pages and grounding queries across Copilot and Bing AI summaries, and Microsoft calls the data a sample. It covers how your own pages were used as sources, which is a different thing from tracking a list of prompts you chose.

That report may change after the cutoff too. David McSweeney, an SEO who posts as top5seo, replied to Gabe with a suspicion that it is full of tracker traffic.

will be interesting to watch BWT AI data here as I suspect many niches are polluted by prompt trackers

David McSweeney, on X, October 29. It is a low-reach reply, and he offers no data.

Where I land

Disclosure: my agency, ViewEngine, sells AI visibility work and builds its own tracking tools.

That is why I would not treat this as only a Semrush story. Any tool that depends on a platform's access can lose it, and Gabe is right to ask who tells customers next. Whether other vendors face the same limit is open, since collection methods differ.

I will export the Bing AI Performance citations and grounding queries now and again after November 9. If other trackers keep prompting Copilot, nothing may change, and a drop in citations would fit McSweeney's theory without proving it. Every report I send will keep visibility changes and measurement changes on separate lines.
