HIGHBingbot allowed
robots.txt permits Bingbot (the crawler behind Microsoft Copilot Shopping's index) at the site root. Microsoft Copilot Shopping ranks results from the Bing index; blocking Bingbot removes you from Copilot answers.
What this check looks for
Microsoft Copilot Shopping reads from the Bing index, which is built exclusively by Bingbot — there is no separate Copilot crawler today. A robots.txt Disallow against Bingbot (explicit or via an inheriting wildcard group) keeps the store out of Bing's index and, by extension, out of Copilot's shopping answers.

The spec it's pinned to
RFC 9309 — Bingbot User-agent groups
Microsoft has not published a dedicated Copilot Shopping crawler. The Copilot answer surface draws from the Bing search index, which is built by Bingbot. Per RFC 9309, blocking Bingbot in robots.txt removes the store from Bing's index — and therefore from Copilot Shopping.
