First, what “AI attribution” has to do

Counting visits from ChatGPT is the easy part, and GA4 does it for free. Attribution means connecting those visits to something you are paid for: an order, a booked job, a signed deal. It also has to deal with the customers who never click. Someone asks an assistant who to hire, then searches your name or phones you, and every analytics tool records them as Google or direct. We cover the reasons in why every AI attribution tool undercounts.

So judge each tool on three questions: what does it tie AI visits to, how does it handle people who didn’t click, and can you check the number it shows you?

1. Google Analytics 4: best free starting point

Since May 2026, GA4 puts recognised AI assistant visits into their own “AI Assistant” channel. It costs nothing and you probably have it already. It shows visits and, if you send purchases into it, revenue. It doesn’t keep named leads, can’t see customers who phoned, and needs an analyst’s patience to set up well. Start here if you only want to see whether AI traffic exists. Our GA4 guide walks through it, and this comparison shows where it stops.

2. Which AI Sent: best for leads, bookings and calls

Our own tool. It follows each visitor from ChatGPT, Gemini, Perplexity, Claude or Copilot to the form, booking or WooCommerce order, and adds a “How did you first hear about us?” question to catch the customers who never clicked. Every AI lead is labelled Confirmed, Declared or Assisted, so the revenue figure is a minimum you can defend. Setup is one click on WordPress, Wix and Google Tag Manager. Where it falls short: no automatic call tracking, no direct Stripe connection, and its visibility check is lighter than a dedicated visibility platform’s. Pick it if you run a service business, a clinic, a trade or an agency that reports to such clients. Plans are on the pricing page.

3. Attrifast: best for Stripe and Shopify revenue

Attrifast joins recognised AI visits to real Stripe payments and Shopify orders, and includes prompt-level visibility tracking. It is the cheapest paid option here. It works from tracked visits, so customers who phoned or searched your name are outside what it can see, and its agency plan is still a waitlist. Pick it if your revenue arrives through online checkout. Full comparison: Which AI Sent vs Attrifast.

4. LeadJourney: best if you also buy ads

LeadJourney is a full marketing attribution platform: ad platforms, multi-touch models, call tracking, and sync with CRMs such as Salesforce and Pipedrive. AI sources are one channel among many. It is priced by marketing spend, so it suits teams with a budget to manage. Pick it if paid ads drive most of your pipeline and you want one tool for everything.

5. Finseo: best for visibility and attribution in one platform

Finseo is mainly an AI visibility platform, tracking how AI models mention a brand across many assistants, with attribution built on “how did you hear about us” answers and GA4 revenue matching. It connects to more systems than anyone else on this list and counts large consumer brands as customers. Pick it if you have a brand team and the budget. Full comparison: Which AI Sent vs Finseo.

6. Targetlytics: best for B2B teams on GA4 and HubSpot

Targetlytics reads GA4’s AI Assistant channel, matches visits to HubSpot deals and shows revenue per assistant with a confidence score. Its site is open about the limits: it only counts visits that reached your site and depends on GA4 recording conversion values. Attribution sits in its higher plans. Pick it if you already live in GA4 and HubSpot and sell to other businesses.

How to choose in one minute

• Paid through online checkout? Attrifast, or GA4 if free is the priority.
• Paid after a call, quote or booking? Which AI Sent.
• Spending heavily on ads? LeadJourney.
• Need to know how AI talks about your brand, at scale? Finseo.
• B2B with GA4 and HubSpot? Targetlytics.

Whichever you choose, add the “how did you hear about us?” question to your forms and calls. It costs nothing and it is the only way any tool can see customers who never clicked. Here is how to word it.
