CS-Cart Speculation Rules Optimizer enhances your store's performance by intelligently preloading pages that customers are most likely to visit next.
By leveraging Google's Speculation Rules API, the add-on automatically prefetches and prerenders pages to reduce loading times and provide a faster, smoother browsing experience.

The add-on predicts customer navigation patterns and prepares the next page in advance, allowing visitors to move between product pages, categories, and search results with minimal waiting time.

This responsive browsing experience keeps customers engaged, reduces bounce rates, and encourages them to explore more products.

Store administrators can choose between Prefetch, Prerender, or a combination of both to optimize loading behavior according to their store's requirements.
The add-on also allows you to define URL matching rules, exclude sensitive pages such as the cart, checkout, and customer profile, and configure loading behavior with flexible settings.

Features
- Predicts customer navigation paths using the Speculation Rules API.
- Automatically prefetches and prerenders pages to boost performance.
- Offers flexible loading modes — prefetch, prerender, or both — to suit your store’s traffic patterns.
- Reduces load time and enhances overall site responsiveness.
- Excludes sensitive pages like cart, checkout, and user profile from preloading.
- Includes built-in debug logs for easy tracking and testing of page behavior.
