40%+ of Buffer's new signups now come from AEO and LLM-driven discovery. We only know that because we ask them. If we relied on click-based attribution, this channel would look like a rounding error. The number comes from a "how did you hear about us" question during onboarding. Without it, ChatGPT, Perplexity, Gemini, and the rest would barely register in our analytics. Referrer data is patchy, the journey is multi-touch, and the click that eventually converts usually shows up as direct or branded search. Two things this has clarified for me: Traditional attribution is already broken for what is, for many products, the largest potential growth surface. If your team is making investment decisions only on what shows up in GA4 or your warehouse, you're underweighting AEO by an order of magnitude. Self-attribution surveys aren't a nice-to-have here. They're one of the few ways to see this channel at all. And AEO isn't something you hack your way into. We work on it deliberately at Buffer, but the work sits upstream of the citation: clear positioning, content worth referencing, and real presence in the places people talk about tools. The brands that LLMs surface have product credibility and honest third-party coverage behind them. You earn citations by being worth referencing, not by optimizing for them. The discovery layer changed quickly. The fundamentals that earn you a place in it haven't.
