Seraphinite Accelerator Premium: Features and Requirements

Remote optimization and Premium support

Seraphinite Accelerator Premium is a paid WordPress performance add-on with remote optimization on the provider's cloud servers. Its allocation is 1,000 CPU seconds per hour, 10,000 per day, and 300,000 per month. Premium removes the free version's limit of 5,000 page views per month for optimization. After that limit, the free version caches pages without optimizing them.

Premium also removes the banner at the bottom of the site and promotions for related add-ons. It includes three hours of personal prioritized support per website. Additional support is listed at 30 EUR per hour, and issues caused by the product are fixed for free.

Cache behavior and page delivery

The file cache is designed to tolerate high loads, while cache revalidation uses minimal resources. Cached data can be separated by device and environment. User-aware caching works with pages that depend on a user, such as shopping carts and online courses, and cached user sessions are protected against brute force attacks.

The plugin supports GZip, Deflate, Compress, Brotli, and uncompressed output. Cache data compression reduces storage use, and browser caching through .htaccess can reduce server load.

Content and media controls

• Multiple CDN support lets sites balance delivery across CDNs and manage costs.
• Lazy revalidation keeps pages available while content is updated.
• Identical cache parts can be stored once to reduce storage use.
• HTML handling checks and corrects unescaped scripts, misplaced tags, and lost tags.
• JavaScript, CSS, and HTML can be minified.
• Images, video, frames, and fonts can be lazy-loaded.
• JavaScript and CSS can be lazy-loaded, inlined, or deferred.
