The tools for optimizing a store for AI shopping agents do four different jobs: they monitor whether AI answers mention your brand, generate listing content, make your catalog readable to agents, or simulate whether an agent picks your product over a competitor's. If your goal is product titles and descriptions that agents choose, look at the last group, the tools that test a listing against a rival and then rewrite it.
I think most of the confusion comes from everyone using the same three letters. "GEO" now covers a dashboard that counts brand mentions and a tool that rewrites your product page, which is a bit like filing a thermometer and a heater under "climate". Fair caveat up front: I co-founded ecentic, which sits in that last group, so I've flagged the bias where it applies and said where a competitor is the better pick.
One market note before the list. Buying inside the answer is live on Google AI Mode and Gemini in the US, and early almost everywhere else, so choose for where this is going and not only for where it is today.
