AI Search Weekly Intelligence Briefing: 24 February 2026

By Adam Parker 24 February 2026

The introduction of advertising inside ChatGPT signals the beginning of paid placement in conversational AI. LLM referral traffic is growing at 80% while representing under 2% of total referrals, confirming the channel is commercially relevant but not yet dominant. AI search is evolving into a measurable channel alongside traditional search rather than replacing it outright.

Executive Snapshot

OpenAI began testing sponsored placements inside ChatGPT for US free tier users, introducing paid visibility alongside organic AI citations. Ecommerce research confirms AI referral traffic converts at a higher rate than non branded organic search, though overall volume remains small.

LLM referral traffic grew 80% over 13 months while accounting for under 2% of total referrals. Google AI Overviews continue to compress click through rates across organic and paid queries. Infrastructure investment from providers such as Cloudflare signals longer term adaptation toward AI agent consumption.
