Does TAMGIO track Microsoft Copilot?

No. Ongoing tracking covers OpenAI web search, Perplexity Sonar and Gemini grounded search, with Google AI Overviews in Audit Mode. Copilot is documented here because buyers ask about it, not because we measure it.

Why does Copilot name different brands than ChatGPT?

Because its retrieval runs through a different index. A brand well covered in one index and thinly covered in the other will appear in one assistant and not the other, with no content change explaining the gap.

Microsoft Copilot

By Shamil Guliyev · Updated 2026-09-15

Microsoft Copilot is an assistant distributed through Windows, Edge and Microsoft 365, answering with grounding in Bing search results. Its distinguishing property is not the model but the distribution: it reaches people inside the operating system and the office suite rather than on a website they chose to visit.

How it picks sources

Grounded answers are assembled from Bing results, so Bing indexing and Bing-visible content decide what can be retrieved at all — a meaningful difference for sites that are strong in Google and weak in Bing. Within the retrieved set, the same properties win as everywhere else: a plain statement of the fact, structure a summariser can keep, and a source that can be linked without ambiguity.

Grounding behaviour

Search grounding is the normal path for informational questions, and answers usually carry citations. Enterprise contexts add a second grounding source: Microsoft 365 content the user has access to, which never appears in external measurement and is not something a public brand can influence. For brand tracking, only the web-grounded, publicly reproducible answers are measurable.

How to track it

Coverage across vendors is uneven, so the first question is whether the tool you buy tracks Copilot at the tier you are paying for — several list it only on higher plans. Where it is tracked, sample it like any other engine, record the citation list, and keep it in its own column: because retrieval runs through Bing, Copilot regularly disagrees with Google-grounded engines about the same brand, and merging them hides exactly that signal.

Measurement mistakes

Assuming Google-indexed means Bing-retrievable. Copilot visibility often fails at the index level rather than the content level.
Merging Copilot into a combined rate with Google-grounded engines, which averages away the one thing Copilot uniquely tells you.
Reading enterprise Copilot answers, which are grounded in private tenant content, as evidence about public visibility.
