In its default settings, Contact Form 7 loads its JavaScript and CSS stylesheet on every page. This slows page loading and taxes server and client resources. Use this plugin to control which pages the scripts load on.
NEW in v1.0.15: The plugin also prevents scripts and styles from the following plugins from loading. If you are using any other plugin that extends Contact Form 7 and loads its scripts on all pages, please open a support ticket and we will look into adding it.
<ul>
<li>Contact Form 7 Conditional Fields</li>
<li>Contact Form 7 Multi-Step Forms</li>
<li>Contact Form CFDB7</li>
<li>Drag and Drop Multiple File Upload — Contact Form 7</li>
</ul>

Often when trying to optimize the Google Pagespeed score, there is one script which still causing the ‘Leverage browser caching’ rule popping up: Google’s own gtag.js and/or analytics.js file…
With this plugin you will be able to cache this file on your local server and enable browser caching for longer than 2 hours. The plugin will check every day if there is a newer version of the file to keep the cache up to date.

Cache External Scripts

Save the Google Analytics file (gtag.js / analytics.js) locally to be able to cache it for longer than 2 hours for a better PageSpeed score!
