By [productknowledgegraph](https://profiles.wordpress.org/productknowledgegraph/) [Download](https://downloads.wordpress.org/plugin/productknowledgegraph.0.2.1.zip) * [Details](https://pirate.wordpress.org/plugins/productknowledgegraph/#description) * [Reviews](https://pirate.wordpress.org/plugins/productknowledgegraph/#reviews) * [Installation](https://pirate.wordpress.org/plugins/productknowledgegraph/#installation) * [Development](https://pirate.wordpress.org/plugins/productknowledgegraph/#developers) [Support](https://wordpress.org/support/plugin/productknowledgegraph/) ## 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. Service terms: https://productknowledgegraph.com/terms Privacy policy: https:// productknowledgegraph.com/privacy ## 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. ## FAQ ### 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. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “ProductKnowledgeGraph – Is AI Recommending Your Competitor Instead?” is open source software.
