ChatGPT Shopping is rewriting the ecommerce buyer journey
ChatGPT Shopping rolled out in late 2024 and the data through 2025 made the impact clear. Buyers are asking ChatGPT for product recommendations directly and converting on the citations the model surfaces. The brands cited by ChatGPT for high intent product queries are pulling traffic and revenue out of Google. The brands not cited are losing share they did not realize was up for grabs.
ChatGPT optimization is the discipline of getting an ecommerce brand cited consistently inside ChatGPT and ChatGPT Shopping responses. It overlaps with broader AEO work but has specific mechanics around how OpenAI’s models retrieve, weight, and cite product information. The 9 agencies below all do this work to varying depth. The top 3 do it as a primary specialization rather than a side offering.
