Semrush is removing Microsoft Copilot from its enterprise AI visibility tracking on November 9, 2026. The company told Enterprise AIO customers by email on October 28; search consultant Glenn Gabe shared the notice publicly a day later. The reason: recent changes to Copilot’s access rules stop visibility platforms from collecting the data they need.
What is being cut
Enterprise AIO tracks how often brands appear in AI assistant answers. The product currently lists nine assistants. Once Copilot leaves, eight remain: ChatGPT, Google AI Overview, Google AI Mode, Perplexity, Grok, Gemini, Claude and DeepSeek.
The notice is brief. Semrush wrote that changes “prevent AI visibility platforms, including Semrush Enterprise AIO, from collecting the data needed to track Copilot performance.” Then it added: “Copilot tracking will therefore be discontinued on November 9.”
Enterprise customers face two options: return unused Copilot prompts to their overall balance, or keep historical Copilot data while those prompts still count against capacity. Semrush gives no deadline and asks clients to contact a customer success manager.
Why Microsoft closed the door
Microsoft has tightened Copilot access through 2026. Consumer terms effective August 18 require a Microsoft account and bar bots or scrapers. Microsoft product manager Krishna Madhavan wrote on August 29 that all Copilot users must log in. Edge began requiring sign-in for Copilot in October.
AI visibility vendors typically send thousands of buyer-style prompts to assistants and parse the answers for brand citations. Sign-in walls and anti-bot terms break that method at scale. Signed-in sessions can also bring personal context into results, which makes the output harder to reproduce.
What marketers should do now
Copilot is a small part of generative AI traffic: Similarweb put it at 2.0% of worldwide generative AI website traffic in May 2026. But it reaches Windows, Edge and Microsoft 365, and Microsoft launched checkout inside Copilot with PayPal, Shopify and Stripe in January, so retail visibility is not hypothetical.
The bigger problem is comparability. Cross-platform share of voice is only as clean as the platform list behind it. When Copilot drops out, totals shift because the denominator changed, not because brand visibility did. Reports that mix before and after November 9 will not measure the same thing.
Microsoft’s own tools fill part of the gap. Bing Webmaster Tools and Clarity show citation and grounding data for a verified site, but they do not show the prompts people typed, competitor coverage, or brand mentions without a citation.
For now, the sensible moves are:
- Audit which AI platforms your visibility vendor still tracks and how it collects the data.
- Keep pre- and post-November 9 share-of-voice reporting separate.
- Use Bing Webmaster Tools and Clarity as first-party complements, not replacements.
This is the same pressure rank tracking felt. Google’s num=100 removal made position tracking harder, but vendors kept collecting. With Copilot, Semrush says collection stops altogether. The control point is no longer the measurement method; it is platform access.
