Speed Booster Pack is made to improve your page loading speed and get a higher score on GTmetrix that uses Google Page Speed and YSlow.

Additional recommendations and best practices to speed up your site:

• Choose a good hosting service – choosing a good web hosting will increase your website performance.
• Enable compression on your website – less time to load your pages, and less bandwidth used over all.
• Use W3 Total Cache plugin – as a minimum configuration, we recommend to use just the full page and browser caching options enabled.
• Use WP Smush.it plugin – reduce image file sizes and improve performance that means less time to load your pages.
• Use P3 Plugin Profiler to see which plugins are slowing down your site. Some poorly coded plugins may impact your site performance.
• If your site running Google Ads, you need to choose the “async” mode for your ads, otherwise your site will get about a 4-5 point hit on Google Page Speed test.

*If you’re using a WordPress cache plugin, make sure you’ve emptied your cache before testing your site performance after checking/unchecking any of the plugin options.

This option move all scripts to the footer while keeping stylesheets in the header to improve page loading speed and get a higher score on the major speed testing sites such as GTmetrix or other website speed testing tools.

Note that this only works if you have plugins or themes that utilizes wp_enqueue_scripts correctly. Since not every plugin developer follows the WordPress standards, you may need to disable this option if you experience issues with such a plugin.

Since some scripts need to be loaded in the header before the “in-page” script, there might be something broken after activating Move scripts to the footer option. Thus you may need to exclude some js files from this option or, more accurate, to place them back to the head, before the “in-page” script.

To understand what are you doing here: basically the option of excluding js files do the following shunting: it deregister the scripts you need to exclude then it add their HTML back into the header. That is not the most standards-compliant means, but it should get the job done if you have problems with any specific plugin.

1. The first thing you need to do is find the handle for the script you want to exclude.

To find the handle for the script you should do a search for wp_enqueue_script through your plugin files. Alternatively, you can ask the author of the plugin for the script handle name.

The handle is the first parameter after wp_enqueue_script(

For example, in the following snippet, the handle is contact-form-7:
wp_enqueue_script( 'contact-form-7',...

Enter this script handle in the first text field on the left as follow:

After you find the script handle, look in the page source of your site and copy the HTML code of the script you want to exclude.
Such HTML code looks similar to the one below:

Now enter this code in the first text field on the right, as follow:

Save the changes and you are done!

If you want to exclude more than 4 javascripts, your page score will be hit and therefore the use of “Move scripts to footer” option will become useless so you can disable it.

This option allows you to exclude some javascript files to be deferred. Enter one by text field, the final part of the js files that you want to be excluded from defer parsing option. For example: jquery.min.js

If you want to exclude more than 4 javascripts, your page score will be hit and therefore the use of “Defer parsing of javascript files” option will become useless so you can disable it

Loading WordPress javascript files from Google’s Libraries rather than serving it from your WordPress install directly, will reduce latency, increase parallelism and improve caching.

By deferring parsing of unneeded JavaScript until it needs to be executed, you can reduce the initial load time of your page.

Please note that this option will not defer the main WordPress jQuery script if Load JS from Google Libraries option is not checked.

Since most proxies do not cache resources with a "?" in their URL, this option allows you to remove any query strings (version numbers) from static resources like CSS & JS files, thus improving your speed scores in services like GTmetrix, PageSpeed, YSlow and Pingdoom.

This option will improve the web page loading times of your images. When is checked, you will notice that your images will be loaded only when they become visible to the user viewport.

If you experience issues with some slideshow or slider plugins, you may need to uncheck this option.

Use this option only if your theme uses Font Awesome, to prevent other plugins that uses Font Awesome, to add their stylesheets to your theme. In other words, this option removes extra Font Awesome stylesheets added to your theme by certain plugins, if Font Awesome is already loaded by your theme, reducing the number of HTTP requests generated by extra stylesheets. Most certainly, you wouldn’t want to see Font Awesome loaded several times in your header, bloating your theme unnecessarily.

Note that this option can be also used safely as a smart way to enqueue Font Awesome stylesheet from CDN if you need it and your theme doesn’t use it yet.

WordPress URL shortening is sometimes useful, but it automatically adds an ugly code in your header, so you can remove it.

WordPress incorrectly implements this feature that supposedly should fix a pagination issues but it messes up, so there is no reason to keep these around. However, some browsers may use Adjacent Posts Links to navigate your site, although you can remove it if you run a well designed theme.

Windows Live Writer (WLW) is a Microsoft application for composing and managing blog posts offline and publish them later. If you are not using Windows Live Writer application, you can remove it from the WP head.

This option is added for security reasons and cleaning the header.

This option wil remove all rss feed links to cleanup your WordPress header. It is also useful on Unicorn – The W3C Markup Validation Service to get rid out the “feed does not validate” error.

Page Load Stats is a brief statistic that displays your homepage loading speed (in seconds) and number of processed queries.

Page loading time – the progress bar color will be:

• green if the page load takes less than a second
• orange when loading the page takes between 1 and 2 seconds
• red if the page loading takes longer than 2 seconds

Number of executed queries – the progress bar color will be:

• green if there were less than 100 queries
• orange if there were between 100 and 200 queries
• red if the page required more than 200 queries

The default image compression setting in WordPress is 90%. Compressing your images further than the default will make your file sizes even smaller and will boost your site performance.

Note that any changes you make will only affect new images uploaded to your site. If you want to update all of your images with the new sizes, install and run the Regenerate Thumbnails plugin.

As a reference, a lower level of compression means more performance. We recommend you choose a compression level between 50 and 75.

Loading CSS asynchronously will render your page more quickly to get a higher score on the major speed testing services.

Activate this option only if you don’t want to use other minify plugins or other speed optimization plugin that has minify option included. If something goes wrong, simply uncheck this option and save the settings.

Minifying and inline all CSS styles will optimize the CSS delivery and will eliminate the anoying message on Google Page Speed regarding to render-blocking css.

Inserting all CSS styles inline to the footer is a sensitive option that will eliminate render-blocking CSS warning in Google Page Speed test. If there is something broken after activation, you need to disable this option.

Please note that before enabling this sensitive option, it is strongly recommended that you also enable the “ Move scripts to the footer” option.

Also, you should not use this option if you don’t have an active caching plugin. Otherwise, the loading of the site will be gradually – FOUC (flash of unstyled content).
