AI Search Expands: Brands Urged to Secure Citations Before Fencing Tightens

The AI search landscape is rapidly evolving, with major platforms now surfacing branded links and paid advertisements. On May 7, OpenAI launched a self‑serve advertising program, while Perplexity opted to pull its own ads, signalling a shift toward monetised brand visibility in AI‑driven queries. According to the article, 62 % of enterprise domains remain technically invisible to AI models, and the median time for a brand to receive its first AI citation is 6.81 days. Earned media mentions account for 81 % of AI citations, whereas paid placements contribute a mere 0.3 %. Forecasts project AI ad spend to reach $2.08 billion in 2026 and $25.9 billion by 2029, underscoring the growing commercial importance of this channel.

The piece outlines a practical strategy for brands to stay ahead of the curve. It recommends conducting an audit of real buyer queries across ChatGPT, Perplexity, and Google AI Mode to pinpoint where a brand is cited. Brands should actively pursue earned media mentions and ensure that AI crawlers such as GPTBot, ClaudeBot, and PerplexityBot are permitted in their robots.txt files. The article stresses that the “fencing” of the AI search field is not governed by a fixed deadline but by competitor awareness; the fastest brands can secure citations within a week of publishing new content.

Reactions to the shift highlight the dual nature of AI search: while it offers a new avenue for organic brand exposure, it also introduces a paid advertising layer that will likely train on the same organic signals. The recommendation is clear: act swiftly—audit queries, chase earned mentions, and adjust robots.txt—to capture both organic and paid opportunities before the field becomes increasingly competitive.
