About this plugin
Shoppers now ask ChatGPT, Perplexity, Gemini and Google’s AI answers which
product to buy. Each answer is a decision made before anyone reaches your
store. So the questions that matter are:
- When a buyer asks AI what to buy, does it show your product?
- If it does, does it describe the product correctly — the right variant,
the right specs, the right use case?
- When it picks a competitor instead, why?
- Does it send the buyer to your store, or to a reseller or marketplace?
- After you fix the product information, does the answer change?
ProductKnowledgeGraph answers those questions for your products and fixes
what can be fixed: it publishes official, source-backed records of your
products that AI systems can read and cite, re-checks the buyer questions,
and shows what changed. This plugin connects your WooCommerce store to it:
- Product schema pointer for AI search. On each product page whose SKU or
GTIN matches an official record, the plugin adds a server-side JSON-LD
subjectOf link to that record, with your product page as the source. No
match — no markup, not one byte. Crawlers see it without running
JavaScript.
- AI Product Coverage dashboard. How many of your products already have
an official AI-readable record, how many do not yet, and your AI Readiness.
- “AI Status” column on the Products list: Published / Not published.
- Your feed on your own domain at /.well-known/productknowledgegraph.json.
- Optional one-click “Share catalogue”. Announces your store’s public
catalogue endpoint so more of your products can be covered by official
records. Nothing is uploaded from your site.
- Safe by default. A 12-hour cache; a temporary fetch failure never
breaks your site or removes markup that was already serving.
The plugin reads your catalogue and writes markup. It does not read orders,
customers or payments, does not load any external JavaScript, and does not
change your page content.

com)
for two things, both under your control:
- Downloading your Official Product Feed from the URL you paste into the
settings. The request is made from your server in the background (at
most twice a day, or when you press “Update Product Records”) and sends
no data about your site, products, orders or visitors — it is a plain
GET of a JSON file. No request is made until you configure the feed.
- Only when you press “Share catalogue”: one POST that announces your
site address, your public WooCommerce Store API URL and your published
product count, so ProductKnowledgeGraph can read your public catalogue
and cover more products with official records. No product data, orders,
customers or visitor data are sent by the plugin itself, and no request
happens without that explicit click.
