AI Visibility Index: How to Track Whether AI Search Actually Recommends Your Store

Somewhere in the last year, the way shoppers find things changed quietly: a growing number of product-born questions now start in an AI search box instead of a ten-blue-links page — "Is brand X legit?", "best budget running shoes for overpronation", "where to buy [product] in France".

You can be #1 on Google for a query and completely absent from the answer the AI generates. And that absence is invisible in every classic SEO report — there is no "AI SERP" tab to check. That is exactly what the new AI Visibility Index in PrestaSEO AI++ measures.

What the AI Visibility Index is

One number: 0–100 — how often and how strongly your store shows up in AI-generated answers to the questions your real shoppers ask. It works the way a good analyst would:

1. You define the questions that matter — the shopper queries most likely to send (or kill) a sale: "is [your brand] legit", "best [your product category] to buy", "[your brand] review".
2. PrestaSEO AI++ interviews the AI itself — daily (or weekly) it asks the same model class powering ChatGPT-style search what it would answer, then checks whether your store is mentioned, recommended — even how positively.
3. You get a score, a trend and an action list — overall index, 7-day trend, per-query Found / Not found / Error, plus concrete suggestions: add FAQ blocks, complete product schema, build a dedicated page for that question.

Put simply: GEO and AEO — Generative and Answer Engine Optimization — turned into a measurable number, without guessing.

Why e-commerce is the canary

Buying is now a two-step ritual: first ask the AI, then click. Stores that appear in the first step win the decision; stores that don't never get a chance to compete on price. AI citing is the new ranking.

If your "is my store legit" score is 30, you now know the AI's first impression is lukewarm — and you can fix what feeds it: structured data, reviews, press, FAQ.

Four quick wins to lift your score this month

• Answer your own questions — each target query deserves a dedicated FAQ or product page the LLM can cite.
• Complete your schema — Product, Offer, AggregateRating and Organization give the AI unambiguous facts instead of crumbs.
• Publish review/authority signals others repeat — AI trusts what people repeat.
• Measure weekly, not yearly — a score you track is a score you can push.

Measure it — then move it

The AI Visibility Index doesn't promise to put you in any answer. It does something more useful: it tells you where you stand in the answers being generated today, and exactly what to do about it. For a store selling to AI-primed shoppers, that's the missing dial on your SEO dashboard.
