 * I just ran a speed test of my site and I’ve received a performance grade of 70.
   Site speed is extremely important to me and I need to get a minimum of 90. The
   following three issues are presenting with a grade of F and 1 with a grade of
   D (I’m not a developer but I can figure almost anything out with the proper documentation).
   Help? Thank you
 * GRADE SUGGESTION
    F0 Combine external JavaScript F0 Combine external CSS F5 Leverage
   browser caching D66 Remove query strings from static resources

 * [@username201701](https://wordpress.org/support/users/username201701/) “Combine
   external JavaScript” and “Combine external CSS” can be accomplished with the 
   HTML Compressor feature, which is included with [Comet Cache Pro](https://cometcache.com/features/).
   Otherwise, you could use another free plugin like [Autoptimize](https://wordpress.org/plugins/autoptimize/).
 * “Leverage browser caching” is also a feature of Comet Cache Pro. Technically 
   browser caching is a feature of your web server, not of Comet Cache, but Comet
   Cache can add the necessary rules to your `.htaccess` file with the Apache web
   server.
 * “Remove query strings from static resources” is not really recommended for WordPress
   sites as many resources use version-specific static resources that require including
   the version number as a query string. Query strings have minimal impact on performance.
