What AI Agents Do to Your Analytics

Last year I would have told you a drop in sessions was bad news. Now I am not sure the number means what it used to.

On my own sites, traffic softened. Enquiries went up, and the people arriving already knew what I do, where I live and roughly what I charge. Nobody had read my about page. Something else had read it for them.

Why the numbers stop agreeing

An assistant reads your pages and answers the question. The person who asked never visits. There is no session, no pageview, no referrer, nothing in the funnel. Your work happened and your analytics has no record of it.

Then a smaller number of people arrive later, usually by typing your name, because the assistant told them who you were. In GA4 that lands as direct traffic, which is where all attribution goes to die.

So the pattern looks like this: less traffic, better traffic, and no visible reason for either. If you are judging your content by sessions you will conclude it stopped working at exactly the moment it started working differently.

The measurement I actually trust now

I stopped treating sessions as the headline and started watching three things instead.

Direct traffic to deep pages. Somebody typing your domain is one thing. Somebody landing directly on a specific article they could not have guessed the URL for means they were handed it.

What people say in the first message. This is the least technical thing on the list and the most useful. When someone opens with a phrase that appears in my writing, that is attribution, and no dashboard will ever give it to me. I read my own enquiries now looking for my own sentences.

And the crawlers themselves. Assistant crawlers identify themselves in server logs. That is a real signal that your pages are being read, arriving before any human traffic shows up.

The thing nobody wants to hear

You are losing a feedback loop, and you do not get it back.

For twenty years the deal was that publishing on the web gave you a visitor you could count. That deal is being renegotiated without your input. The reading still happens. The visit sometimes does not. You cannot opt out of that by blocking crawlers, you can only opt out of being read.

I made peace with it faster than I expected, because when I looked honestly at what sessions ever told me, the answer was not much. A session is not a client. It never was. It was a proxy I trusted because it was easy to count.

What I would not do

I would not block assistant crawlers to protect a metric. That is choosing a number over the outcome the number was supposed to represent.

I would not build a dashboard for this. I tried. The data is too thin and too indirect, and a chart made from weak signals gives you false confidence rather than information.

And I would not chase a traffic recovery. If your enquiries are fine and your traffic is down, your traffic is not the problem you have.

What this changes about writing

One thing, and it is a big one. If a page is going to be read by software and summarised for someone who will never see it, then the page has to survive being compressed.

Writing that depends on layout, on a striking image, on the reader's mood, does not survive that. Writing that makes a claim in a sentence does. So I write shorter, I answer the question in the first paragraph, and I put the specific number or the specific date in the text rather than in a graphic.

That has made my writing better for people too, which is the same thing I keep finding everywhere else in this work.

Common questions

Can I see which assistant sent someone?
Mostly no. Some referrals are labelled, most are not, and the majority of the value shows up as direct traffic or as a message that arrives out of nowhere.

Should I block AI crawlers?
Only if you genuinely do not want to be cited. For most people reading this, being read by an assistant is the distribution, not the theft.

Is there a tool for this yet?
There are several claiming to be. I have not found one whose numbers I would defend in a meeting. Server logs and reading your own inbox are unglamorous and honest.

So what do I report to a client?
Enquiries, and what those people knew before they arrived. That was always the real number. The traffic chart was a comfortable stand in for it.
