The seven checks of the audit
The audit reads a sample of public pages, at one point in time, and gives you a grade from A to E.
| Check | Question asked |
|---|---|
| robots.txt | Are the assistants' search robots allowed to read the store? |
| Upstream blocking | Does a firewall or a content delivery network refuse them before they reach the store? |
| Discovery | Can product pages be found from the home page and the sitemap? |
| Structured data | Do the pages describe the product, its price and its stock in a machine-readable way? |
| Indexability | Do the pages respond, without any ban on indexing? |
| llms.txt | Does the store publish this home file for assistants? |
| Feed hints | Is there a trace of a product feed? |
Collection
The engines and the provider
Engines queried: ChatGPT, Perplexity, Gemini and Google AI Overviews. The engines tracked depend on the plan (table on the pricing page).
Provider: we query the engines through DataForSEO. We send it the buying questions and the store's brand and product names. No data about your customers.
Retention: the texts of the answers are kept for 90 days; the observations (cited or not, engine, date) for as long as the account exists.
This site
What this site counts
This site uses no third-party tracker and sets no measurement cookie. It keeps four counters: visits to the audit page, audits started, emails entered, clicks on an offer. Each counter keeps only a day and an event name: no IP address, no email, no store address.
ChatGPT, Perplexity, Gemini, Google, PrestaShop, WooCommerce and Shopify belong to their owners. ChatCommerce is not affiliated with any of them.
