SEO Pro Suite: Rich Snippets, Canonical, Hreflang & llms.txt
Edition: CS-Cart & Multi-Vendor · Latest version: 1.0.1 · Compatible with: CS-Cart & Multi-Vendor 4.17.2 – 4.21.x, PHP 7.4 – 8.3 · Changelog: view
Technical SEO on top of the CS-Cart SEO add-on. It completes the product rich-result data Google uses for merchant listings, adds the structured data the core does not print (FAQ, breadcrumbs before 4.21, organization, site name, blog posts, vendor stores), gives you robots, canonical and hreflang rules, prints Open Graph and Twitter (X) cards on every page, and prepares your store for AI search with a generated /llms.txt and AI crawler rules in robots.txt. A page check in the admin panel shows what search engines see on any page of your store.
Key features
Section titled “Key features”- Product rich results: item condition, seller, return policy, shipping details, price validity, GTIN from barcode-like product codes, MPN and brand fallbacks, merged into the product markup of the core SEO add-on (no duplicate Product blocks).
- More structured data: FAQPage, BreadcrumbList (on versions before 4.21, which have none), Organization with address, phone, e-mail and social profiles, WebSite (site name), BlogPosting on blog posts, OnlineStore on Multi-Vendor vendor pages. On 4.21 the core Organization item is completed, not replaced.
- FAQ editor on products, categories and pages: questions and answers shown as an accessible accordion on the storefront and as FAQPage data. Vendors can edit the FAQs of their own products (optional).
- Robots rules by page type: paginated, sorted and search result pages, out-of-stock products, empty categories, vendor pages. Per product, category and page override. Large-preview directives for Google Discover and AI overviews.
- Canonical links on pages the core leaves without one (information pages, vendor pages), removed from noindex pages.
- Hreflang control: region codes per language (
en-US,fr-CA), x-default choice, exclusions, or off. - Social cards: complete Open Graph and Twitter (X) tags for the home page, products (with price and availability), categories, pages, blog posts and vendors; default share image; replaces the partial tags of the Social buttons add-on.
- AI search: generated
/llms.txt(store facts, categories, popular products with prices, pages) and an AI crawler policy (allow, block AI training, block all) written to robots.txt as a marked block. - Page check and catalog coverage in the admin panel: title, description, robots, canonical, hreflang, social tags and every structured data block of a page, with Google’s required and recommended properties; counts of products without GTIN, brand, image or meta description.
