W3 Total Cache (W3TC) improves the SEO and user experience of your site by increasing website performance and reducing load times by leveraging features like content delivery network (CDN) integration and the latest best practices.
W3TC is the only web host agnostic Web Performance Optimization (WPO) framework for WordPress trusted by millions of publishers, web developers, and web hosts worldwide for more than a decade. It is the total performance solution for optimizing your WordPress Website.
W3 Total Cache Pro features
Fragment Caching Social layer, personalization and e-commerce etc are common elements of highly dynamic web sites. That means that caching entire pages to improve user experience and performance is not a solution. Fragment Caching bridges the gap between no caching at all and the “ideal,” full page caching. By extending the WordPress Transient API, W3TC allows developers to bring both horizontal and vertical scale to bear without doing anything differently.
Extension Framework As mentioned above, extensions / add-ons represent a great opportunity to both de-bloat projects that solve many problems or address many use cases. It also allows for innovation as 3rd parties can make contributions without having to be a core project developer to contribute or solve their problems while maintaining the control they need. We’re excited for you to try this first iteration of our extension framework, and documentation can be found (for now) inside the plugin’s FAQ.
Note: W3 Total Cache Pro unlocks features in the product, but does not automatically configure them. Upgrading to W3TC Pro is a great idea and recommended for all publishers, but this does not automatically improve page load times or optimization scores.
