Until this week, most sites could tell you two things about AI. Which crawlers read their pages, and how many people clicked through from ChatGPT or Perplexity. What happened when an agent showed up and tried to do something was mostly a guess.
On November 4, Microsoft Clarity added that third view. The free analytics tool now has an Agent Activity dashboard that shows which AI agents visit a site and what they do after they arrive. It also has simulations that send an agent through a task and report whether it finished.
What the dashboard records
The dashboard tracks agent traffic over time, which agents came, and their actions. Microsoft lists searches, form submissions, logins, downloads, appointment bookings and checkout.
That list is the point. A crawler reads a page. An agent acting for a buyer fills in the demo form, opens the pricing page, or gets stuck at a login wall. Those are different events, and a typical analytics setup filters both out as "bot traffic".
The supported agent operators are Google, OpenAI and Anthropic. Microsoft does not say on the launch page how it tells an agent apart from a person or a plain crawler.
The simulations
The second half is a test you can run. Clarity sends an agent through a task on your site and reports whether the task was completed, how long it took, how many interactions it needed, and where it could be improved.
Simulations start with commerce and travel scenarios. Microsoft says more customer journey types will follow. So for now the question it answers is "can an agent buy something here" or "can it book a trip", not "can it book a demo with a B2B vendor".
The numbers behind it
Microsoft says weekly sessions from AI agents nearly doubled in three weeks, to almost 2 million. Its own analysis covered 5.23 million agentic sessions across 230,511 Clarity projects between August 13 and September 9, 2026.
Those are big numbers for a new kind of visitor, and small ones next to human traffic. Two million weekly sessions spread over hundreds of thousands of sites is a few visits per site. The growth rate matters more than the total, because it says the curve has started.
Nabil Naghdy, who wrote the announcement, put the problem plainly: "most websites are built for people, not agents."
Three kinds of AI traffic, one free tool
Clarity has been adding these views for a year. AI channel groups, which separate referrals from ChatGPT, Claude, Gemini, Copilot and Perplexity, came in August 2025. A Bot Activity dashboard for AI crawlers, which needs a connected CDN, arrived on January 21, 2026. Now agents.
Read together, they map the three ways AI reaches a site. Crawlers read the pages an engine will quote. Answer engines send people who already heard your name in an answer. Agents act on a person's behalf and may never send a human at all.
The same release added Brand Agents, a shopping assistant grounded in a store's live catalog whose products can appear in Copilot, Bing and MSN for eligible Shopify and WooCommerce merchants, and Ask Clarity, a question box over your data that is still in closed beta for retailers.
What it does not tell you
Three operators is not the whole field. An agent from anyone else either shows up as something else or does not show up at all. And the dashboard only sees what happens on your own site. It cannot tell you which vendors an agent compared before it arrived, or why it skipped you.
That second gap is the bigger one for a B2B company. If ChatGPT never names you when a buyer asks for a shortlist, no agent comes to fill in your form, and the dashboard shows nothing. An empty report can mean the site works and agents are not sent there.
Still, it is free, and it turns a guess into a count. If you sell anything a buyer could ask an agent to research or book, install it, watch which pages the agents open, and run a simulation once one fits your flow.
The bigger picture
Answer engines decide which vendors make the list. Agents then go and check the ones on it. Clarity now measures the second step on your own pages, which is useful, and it makes the first step easier to forget, which is a risk.
The first step is where most B2B startups lose. A buyer asks which tool fits their team, the model answers from comparison pages, reviews and threads, and a company that is missing from those sources is never visited by anyone, person or agent. Measure the visits, and also measure the answers that come before them.
