About ProductKnowledgeGraph

From the official readme · v0.2.1

Description

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.

External Services

This plugin connects to ProductKnowledgeGraph (productknowledgegraph.com)
for two things, both under your control:

  1. 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.
  2. 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.

Installation

  1. Install the plugin from Plugins → Add New and activate it.
  2. Open your ProductKnowledgeGraph account, go to Integrations → WooCommerce
    and copy your Official Product Feed link. No account yet? Create one free
    at https://productknowledgegraph.com/pilot
  3. Paste the link under Settings → ProductKnowledgeGraph and press Start
    Setup.

Frequently asked questions

Will my products appear in ChatGPT Shopping or AI answers?

Nobody can promise that, and we do not. What the plugin does is make your official product facts easy for AI systems to find and attribute to your store, and point from your product page to them. Whether a given answer uses them is the AI system’s decision.

Do I need a ProductKnowledgeGraph account?

Yes. The plugin connects your store to your official product records, and those live in your account. You can create one free at https://productknowledgegraph.com/pilot

How are products matched?

By SKU or GTIN (UPC, EAN, ISBN) — never by name or URL. A wrong link is worse than none.

Does it slow my site down?

No external requests happen on page views; the feed is fetched in the background at most twice a day.

What data leaves my site?

Nothing on page views, ever. If you press “Share catalogue”, the plugin sends exactly three facts once: your site address, your public Store API URL and your published product count.

Changelog

Text changes only: clearer description, where to find the feed link, and a direct link to the Pilot plan. No behaviour changes.

0.2.1

  • Name and description say the problem it is for: AI choosing a competitor’s
    product, describing yours wrongly, or sending buyers elsewhere.
  • The settings page says where the feed link is (Integrations → WooCommerce)
    and how to get an account.
  • “Run AI Audit” opens the Pilot plan instead of the home page.

0.2.0

  • Dashboard: AI Publication Status, AI Product Coverage, AI Readiness.
  • “AI Status” column on the Products list.
  • One-click “Share catalogue” (explicit, disclosed, off by default).
  • GTIN read via the WooCommerce getter (fixes a notice on WooCommerce 9.2+).
  • First-connection fetch: Start Setup lands on a connected dashboard.

0.1.0

  • Initial release: subjectOf pointer by SKU/GTIN, well-known manifest,
    12-hour cache, admin status page.
