AI SEO for ecommerce is the practice of optimizing your store so AI systems like ChatGPT, Perplexity, Google AI Overviews, and Gemini can find your products, understand them correctly, and recommend them in response to a shopper's query.
This is a different job than ranking on a Google results page. An AI system reads across many sources, synthesizes them, and gives the shopper a single answer. Your job is to be one of the sources it trusts enough to use.
