Page Cache Test (Server Side Caching)100% of top 100 sites passed
  • It doesn't appear that this website is caching webpages. Cached pages serve up static html and avoid potentially time consuming queries to your database. It also helps lower server load by up to 80%. Caching most visibly benefits high traffic pages that access a database, but whose content does not change on every page view. Common caching methods include Alternative PHP Cache, Quickcache, and WP Super Cache (for Wordpress sites). Caching mechanisms also typically compress HTML, further reducing page size and load time.
