WP Speed of Light is a comprehensive WordPress speed optimization plugin that accelerates website performance through multiple techniques. The plugin combines a powerful static cache system with resource optimization tools including minification, file grouping, database cleanup, and .htaccess optimization. It generates static HTML content to reduce database queries, implements GZIP compression for faster data transfer, and enables browser caching to store heavy resources locally. The plugin also offers advanced features like cache preloading, image compression, DNS prefetching, and progressive lazy loading to deliver maximum speed improvements.

Yes, WP Speed of Light has dedicated integrations with WooCommerce and all major page builders. For WooCommerce, it can disable unnecessary styles and scripts on non-WooCommerce pages, disable cart fragments, and includes specialized database cleanup for customer cart sessions. The plugin is fully compatible with Elementor, DIVI Builder, Beaver Builder, Gutenberg Editor, and WP Bakery (formerly Visual Composer). It automatically cleans cache when content is edited and works seamlessly with both frontend and admin editing modes.

WP Speed of Light directly targets Core Web Vitals through its comprehensive dashboard that monitors website health indicators. The plugin improves Largest Contentful Paint (LCP) through caching and image optimization, enhances First Input Delay (FID) with JavaScript defer loading and file grouping, and optimizes Cumulative Layout Shift (CLS) through progressive lazy loading. Features like image compression, lazy loading, and cache preloading specifically address loading speed metrics that Google uses for search rankings. The built-in speed testing tool allows you to measure improvements and track Core Web Vitals performance.

Yes, WP Speed of Light includes advanced image optimization features in the Pro addon. The plugin offers progressive lazy loading that initially displays a low-resolution, blurred placeholder (only 20 pixels) while the full image loads in the background. This creates a smooth visual experience without impacting SEO since all image metadata (alt tags, titles, filenames) loads immediately. The plugin also includes image compression through ImageRecycle integration, reducing JPEG and PNG file sizes by up to 85% while maintaining visual quality. The lazy loading works in both scroll directions and preloads content 2x screen height for fast connections.

WP Speed of Light Pro costs $49 for unlimited websites with no recurring payments or domain limitations. The license includes 1 year of updates and support, plus 3GB of image compression quota that works across all your websites. The plugin is also available as part of JoomUnited's WordPress Bundle, which provides access to all WordPress plugins for unlimited websites. The free version is available from the WordPress repository with core caching and optimization features.

Yes, WP Speed of Light includes comprehensive CDN integration compatible with all major providers including Cloudflare, Amazon CloudFront, MaxCDN, KeyCDN, and others. The plugin offers automatic cache cleanup specifically for Cloudflare CDN, MaxCDN, KeyCDN, Varnish Cache, and SiteGround SuperCacher. You can configure selective CDN caching and purge individual files as needed. The global optimization approach means you can run the same configuration across multiple websites and CDN setups.

WP Speed of Light provides sophisticated mobile caching with device-specific optimization. The plugin can automatically serve cache for all devices (desktop, tablet, mobile) or generate dedicated cache versions per device type. You can enable or disable caching for specific device types, and the system works automatically with mobile plugins like WPtouch. The mobile cache detection ensures your responsive theme loads optimally on different screen sizes while maintaining fast loading speeds across all devices.

Yes, WP Speed of Light includes comprehensive database optimization tools. The plugin provides database speed testing to identify performance bottlenecks caused by themes or plugins. The Pro addon offers automatic database cleanup at defined intervals, removing unnecessary data like spam comments, post revisions, and expired transients. For WooCommerce sites, it specifically cleans customer cart sessions and reduces database overhead. The database cleanup helps maintain optimal query performance as your website grows.

WP Speed of Light is fully compatible and extensively tested with several popular WordPress page builders. These include Elementor, DIVI Builder, Beaver Builder, Gutenberg Editor, and WP Bakery (formerly Visual Composer). The plugin can speed up content created with these builders and automatically cleans the cache after editing, ensuring a seamless workflow for developers and agencies.
