Speed Booster Pack


A short video about how Speed Booster pack can help actually increase a website’s score in Google PageSpeed Insights:

Speed Booster Pack is a lightweight, frequently updated, easy to use and well supported plugin which allows you to improve your website’s loading speed.

Improving your site’s speed will get you a better score on major speed testing services such as Google PageSpeed, GTmetrix, YSlow, Pingdom, Webpagetest and will also improve your overall site’s usability. This will persuade Google and other search engines to rank your site higher in search results thus sending more traffic.

Why Site Speed Is Important?

Visitors usually close a website if it doesn’t load in a few seconds and the slower a site loads the greater the chances are that the visitors will leave. And you don’t want that to happen, do you? πŸ™‚
Speed Booster Pack is a plugin that can help you speed up your website by tweaking different options.

Main Plugin Features

  • Eliminate external render-blocking javascript and css in above-the-fold content.
  • Move scripts to the footer to improve page loading speed.
  • Load CSS asynchronously to render your page more quickly and get a higher score on the major speed testing services.
  • Minify and inline all CSS styles and move them to the footer to eliminate external render-blocking CSS and optimize CSS delivery.
  • ** Minify HTML and JavaScript to increase your page load speed.
  • Change image compression level to keep file sizes smaller; Change JPG quality.
  • Load javascript files from Google Libraries rather than serving them from your WordPress install directly, to reduce latency, increase parallelism and improve browser caching.
  • Defer parsing of javascript files to reduce the initial load time of your page.
  • Remove query strings from static resources to improve your speed scores.
  • Remove extra Font Awesome stylesheets added to your theme by certain plugins, if Font Awesome is already used in your theme.
  • Remove junk header tags to clean up your WordPress Header.
  • Display page loading time in the plugin options page.
  • Display the number of executed SQL queries in the plugin options page.
  • Display the Peak Memory Used in the plugin options page.
  • Exclude scripts from being moved to the footer or defered.
  • Remove RSD Link if you are not using a Weblog Client or some 3rd party sites/programs that use the XML-RPC request formats.
  • Remove WordPress Shortlink
  • Remove the WordPress Version this option is added for security reasons and cleaning the header.
  • Remove all rss feed links to cleanup your WordPress header.

  • For complete usage instructions visit Plugin Documentation

Future Development:

  • Enable compression option.
  • Leverage browser caching.
  • Option to disable specific plugin actions on specific pages directly via the page edit screen metabox.
  • Option to keep specific scripts in the header, since there are many javascript-based plugins scripts, that rely on jQuery to be loaded prior to the HTML elements.

Works great

Seems it’s better than all other “Speed Plugins” i’ve tested on my sites. Really increased speed on all of my sites. Better than plugins i paid lot of money for over the years.. Thx Great work. Pls keep updating your plugin!

Great support

I only started to use this plugin and somehow I made my site break.
I searched for online solutins and did not find any.
I opened a ticket in the plugins’ support page but took into consideration
that I can not wait for a reply as it will take time.
After few short minutes I received a reply with the simple solution !
Saved my day…

This one actually helps!

Tested so many plugins that claim to improve performance, but this is one that actually works.

Saw 10%+ improvement in my PageSpeed and YSlow scores.

wast of time

This is what I got:
