A high intent-to-lead rate is not the same as a high close rate. That gap is the single most useful thing in Invoca's new report on AI-referred phone calls, released July 13 and covered on July 15, and it should change how brands grade their AI visibility.
Most teams still judge generative search by website clicks: did ChatGPT or Google's AI Mode send traffic, and did that traffic look engaged? Invoca's dataset is one of the few that follows an AI referral past the click, into a phone call, and all the way to whether a sale actually closed. What it found is a clean warning against stopping at "high intent."
Key takeaways
- ChatGPT-referred calls became sales leads 49% of the time, roughly 10 percentage points above the seven-channel average, per Invoca.
- But those leads closed at only 40%, below the all-channel close rate of 42% — better qualified in, not better converted out.
- Google Business Profile calls became leads 43% of the time, also above average, showing the pattern is not unique to ChatGPT.
- The read: ChatGPT likely does more research and filtering before the call, so the buyer arrives further along — but price, inventory, and sales handling still decide the sale.
- Practical rule: measure AI sources down to close rate, average order value, and gross margin — never report lead quality alone.
What the numbers actually say
Invoca analyzed roughly 70 million calls and 600 million minutes across 10 industries. Among its customers, calls that came from ChatGPT turned into qualified sales leads 49% of the time — about ten points above the average across the seven tracked channels. Google Business Profile sat at 43%. On the surface, that is a strong endorsement of AI-driven discovery.
Then the curve bends. Those same ChatGPT leads closed at 40%, under the 42% all-channel average. So the channel that produced the highest share of qualified leads produced a below-average share of won deals. The chart below lines the two rates up side by side, and the story is in the crossover.
The most likely explanation is selection, not magic. A shopper who has already talked to ChatGPT has probably compared options, read specs, and narrowed the field before dialing — so more of those callers are genuine buyers, which lifts the lead rate. But being a serious buyer does not guarantee the deal. Whether the price fits, the item is in stock, the rep handles the call well, and fulfillment delivers — those still decide the close, and they are outside the AI engine's control.
