Google, and by now ChatGPT too, only read a shop as well as it is marked up. Without markup, price, availability and reviews stay invisible to both. Afterwards your range is machine-readable — without you having to touch the template.

Structured Data & AI Search Plugin for JTL-Shop (from version 5.5)

Search engines and AI assistants only take from a page what is marked up for machines. Without that markup, price, availability, brand and ratings stay invisible to Google - and to ChatGPT, Claude or Perplexity even more so.

This plugin adds complete JSON-LD to your shop, following the Google and schema.org specifications, without you touching a line of code. It is meant for merchants who want to appear in rich results, in the Google Shopping surfaces and in AI answers.

Key features

Product and offer: name, images, description, article number, brand, price, currency and availability - exactly as the page shows them.
Validated GTIN: the barcode is checked against the GS1 check digit and only emitted when it really is an EAN.
Shipping and returns: shipping cost, delivery time and return window as OfferShippingDetails and MerchantReturnPolicy - the fields Google wants for merchant listings.
Reviews: average and count of the approved product ratings, with individual reviews on request.
Breadcrumb: the category path on product and category pages, taken from the real shop categories.
Organisation and search: organisation with address, contact and social profiles, plus the shop search for the sitelinks searchbox.
Category lists: ItemList in the order the page renders the products.
AI search via llms.txt: a file following llmstxt.org in the shop root listing categories, bestsellers and key pages - kept up to date automatically.
Simple configuration: every service can be switched on and off on its own. Everything else comes from the shop's own master data.
