About

Leading AI-native answer engine; primary non-Google/Bing search challenger in the generative AI era; central reference point for GEO strategy and AI search monetization debate

Perplexity is a conversational AI-powered search engine that generates answers to user queries. Its primary ad format is a sponsored query that appears after a user submits a prompt, with a sponsored slot surfaced among AI-generated follow-up questions at the bottom of the results page. Rather than a cost-per-click model, Perplexity charges advertisers on a CPM basis, reflecting a focus on brand awareness over direct-response. Ad buyers have struggled to measure performance metrics such as click-through rates and return on ad spend, as the platform lacks the measurement tools offered by established ad players. As of late 2025, Perplexity paused accepting new advertisers while rethinking how ads fit into its experience, with its head of publisher partnerships confirming that advertising is not on the roadmap for its Comet browser.
