Growth Intelligence Brief #17
Semrush’s 17‑month clickstream study reveals that between 65% and 85% of ChatGPT prompts have no equivalent keyword in traditional search databases, making most AI‑driven queries invisible to conventional SEO tools. At the same time, ChatGPT’s outbound referral traffic surged 206% year‑over‑year, and the proportion of that traffic returning to Google climbed from 14% to over 21%, indicating a complementary discovery loop. The brief also warns that AI‑generated overviews are error‑prone and highlights Shopify’s strategic bet on AI agents as the next product‑discovery interface. Marketers are urged to broaden measurement beyond keyword lists and capture AI citations.
