FAQ

Frequently Asked Questions

Will this work with my custom OpenCart theme?

Yes. The extension uses OpenCart's native event system — it hooks into the product page render cycle rather than modifying any templates directly. It works with any theme, including custom-built ones. If you encounter any compatibility issue, custom adjustments are provided free of charge with every purchase.

How quickly will Google start showing rich results?

Rich results appear once Google recrawls and reindexes your product pages — typically within a few days to a few weeks depending on crawl frequency. You can accelerate this by submitting your sitemap in Google Search Console and using the URL Inspection tool to request indexing of key product pages immediately after installation.

Do I need to configure each product individually?

No. Shipping details and return policy are configured once in the admin panel and automatically applied to every product page in your store. Product-specific data — name, price, images, reviews, SKU, GTIN — is pulled automatically from your existing OpenCart product data with zero manual work per product.

Does it support sale prices and strikethrough pricing?

Yes. When a product has a special (sale) price set in OpenCart, both the current sale price and the original price are declared using Google's priceSpecification format introduced in February 2025. This enables the strikethrough price display in Google Shopping results and rich snippets automatically.

What product identifiers are supported?

The extension supports SKU, MPN, and ISBN. For barcodes, it includes smart GTIN detection — EAN, UPC, and JAN values from oc_product_code are automatically mapped to the correct gtin8, gtin12, gtin13, or gtin14 field based on digit count, matching Google's specification exactly.

What OpenCart versions are supported?

The extension is built for OpenCart 4.x. It uses OpenCart 4's event system and controller architecture. OpenCart 3.x is not currently supported as the codebase is significantly different. Check the OpenCart Marketplace listing for the latest version compatibility details.

What support is included with my purchase?

Every purchase includes 1 hour of free support. This covers installation assistance, configuration help, and custom theme adjustments if your theme requires any. Support is provided by the developer via the OpenCart Marketplace messaging system.
