Conversion Rate Benchmarks
Average conversion rate on AI search paid traffic is 2.1 to 3.4 percent across categories, materially higher than traditional search (typically 1.0 to 2.5 percent). The lift reflects the qualified nature of AI-assisted research; users arriving via AI search are typically further into the decision process.
Cost vs Traditional Search
AI Mode CPCs run 1.3-1.6x higher than traditional Google Search CPCs across most verticals; Perplexity CPCs run 0.7-1.1x of traditional Search CPCs. Conversion rate is typically 1.2-1.8x higher than traditional Search, which offsets the CPC premium. Effective cost-per-conversion is roughly comparable to traditional Search in most verticals.
Paid-vs-Organic Interaction
Paid AI placements convert 2.3x higher when the brand is also organically mentioned by the AI in the same response. Brands with weak organic AI visibility see paid placements deliver lower conversion than the benchmarks suggest; paid placements cannot substitute for organic AI presence, only complement it.
Budget Floors
Perplexity sponsored questions: $5,000/month minimum; branded answers: $15,000/month minimum. Google AI Mode: no minimum (extends existing Google Ads campaigns). ChatGPT Ads: $25,000/month minimum during the beta phase, with select partner programs at $200K+/month.
How Presenc AI Helps
Presenc AI tracks both paid placements and organic mentions of your brand across AI platforms. The dual tracking is required to interpret AI paid CPC benchmarks correctly: paid placements deliver the benchmark conversion rates only when the brand has the organic presence that the paid placement compounds. Brands evaluating AI advertising investment use Presenc to size the organic foundation work required to make the paid investment pay back.
