WordPress plugin maker Barn2 said it spent $477 on ChatGPT ads over six weeks, generating 19,154 impressions, 370 clicks and zero conversions across two campaigns, while organic ChatGPT referral traffic to the same sites converted normally. The result, posted to Barn2's blog Oct. 6, contrasts with a vendor case study OpenAI touted this month: DV Rockerbox measured WeightWatchers' ChatGPT ad cost-per-acquisition at 15.3% below its blended paid-search benchmark, a figure the wire reported Oct. 5 — OpenAI disclosed no spend or sample size behind it.

Why it matters: Two advertiser results pointing in opposite directions, one self-reported by OpenAI's own measurement partner and one independently published by the advertiser itself, show ChatGPT ads still lack the broad, disclosed performance data buyers need to judge the channel.

## What this answers

**Do ChatGPT ads convert for e-commerce advertisers?**

Results are mixed: WordPress plugin maker Barn2 spent $477 over six weeks and logged zero conversions, while OpenAI's own case study for WeightWatchers, run through DV Rockerbox, claimed a 15.3% lower cost-per-acquisition than its paid-search benchmark.
