ChatGPT ads hit a 33% irrelevancy rate — is the targeting model broken?
searchable found that 33% of chatgpt ads shown in july and august appeared in irrelevant conversations, challenging the platform's promise of contextual targeting.
a study of 11,000 ads served inside chatgpt between july 4 and august 4 found a significant failure in contextual targeting, with 33% of ads appearing in irrelevant conversations. search firm searchable determined that the ad placement logic frequently misses the semantic nuance of the user's query, serving ads that do not align with the specific context of the discussion. this breakdown undermines the value proposition of conversational advertising, which brands expect to be more precise than standard web display ads. the findings imply that simply having a large language model handle conversations does not automatically guarantee ad relevance, signaling a need for better integration between the generative model and ad delivery systems.
