ChatGPT ad targeting is garbage

An experiment with ChatGPT ads for event seating software from August 5-28, 2026, revealed poor targeting and low-value visitors. Despite a low average CPC of £0.10 and 2,988 clicks from a total spend of £289.52, the average time on page was only 7 seconds, with a 69% bounce rate. The conversion rate from click to install was a mere 0.46%, resulting in a high cost per conversion of £20.68 for only 14 installs. The issue was attributed to low-value visitors rather than bots, suggesting ineffective ad targeting.
