2x-5x improvement in your Page Speed score. A completely new way of optimizing your page speed.
== Description ==
WP Meteor offers an original way to further optimize your website speed.
With this plugin you can **increase your PageSpeed score** by up to 5x.
The plugin is 100% free, it is compatible and works well with most popular caching plugins like:
* Autoptimize
* WP Rocket
* WP Total Cache
* WP Super Cache
* Phastpress
* LiteSpeed
* Hummingbird
* WP Fastest Cache
* SiteGround Optimizer
It also works well with website builders like Elementor or with image optimizers like ShortPixel.
The few known incompatibilities are listed in the FAQ.
= BENEFITS =
WP Meteor can improve your [Pagespeed](https://pagespeed.web.dev/) results and the actual loading time of your website by **up to 5x**! You do not have to take our word for it, it only takes 2 minutes to install the plugin and [test how it improves](https://test.fastpixel.io/) your website speed.
And since the plugin is designed to leave no traces on your hard drive or database when deactivated and removed, **there is no risk for you**.
= HOW IT WORKS =
If the user does not interact with the page immediately, WP Meteor defers loading and firing scripts until the page is rendered, which increases the pagespeed metric, on average, by **2-5x**.
This delay in loading scripts greatly improves perceived load times for your visitors. It also significantly improves the following **important SEO metrics**:
* [Page Speed](https://pagespeed.web.dev/)
* [Largest Contentful Paint (LCP)](https://web.dev/lcp/)
* [Time To Interactive (TTI)](https://web.dev/tti/)
* [Total Blocking Time (TBT)](https://web.dev/tbt/)
== FURTHER ACCELERATE YOUR WEBSITE ==
If you want to optimize your website's speed to the fullest extent automatically while ensuring that all Core Web Vitals are taken care of, we recommend trying [FastPixel.io](https://wordpress.org/plugins/fastpixel-website-accelerator/) for free.
The **FastPixel** project is a collaboration between the creator of WP Meteor and ShortPixel, and it addresses, with just a few clicks, [all the common issues](https://fastpixel.io/blog/easy-way-to-improve-core-web-vitals-on-wordpress/?utm_source=wpmeteor-readme#common-issues-affecting-core-web-vitals) that affect Core Web Vitals.
== Frequently Asked Questions ==
= Can this plugin be used on any website? =
While the plugin may not be compatible with every setup, it's important to note that delaying scripts can have drawbacks in some cases.
* For mission-critical websites, we strongly recommend thorough testing of essential pages, forms, and your checkout process. If you encounter any issues, please report them by [creating a support ticket](https://wordpress.org/support/plugin/wp-meteor/#new-topic-0).
* It's worth mentioning that the plugin is designed to leave no residual data on your server or database upon deactivation and removal. You are welcome to install it and assess its suitability for optimizing your site.
* After installing the plugin, we advise performing a comprehensive site test. If the results don't meet your expectations, you have the option to uninstall the plugin. Alternatively, you can explore [FastPixel Website Accelerator](https://wordpress.org/plugins/fastpixel-website-accelerator/).
= Known issues =
* WP Meteor is not compatible with Nitropack.
* Also, WP Meteor is known to have delay issues withElementor Offcanvas addon.
* Using the "Infinite Delay" option will postpone the activation of Google Analytics (GA) and Google Tag Manager (GTM) until there is user interaction. While we do provide this option due to popular demand, I do not recommend its use. If you choose to use it, please exercise caution and be aware that you do so at your own risk.
= How can I easily compare speed with/without WP Meteor ? =
Once WP Meteor is enabled, you can add the query string parameter ?wpmeteordisable to a page URL to load the page without optimizations.
= How do I exclude a page from optimization? =
Use the `wpmeteor_enabled` filter and return false to disable WP Meteor completely, as in this example:
add_filter('wpmeteor_enabled', function ($value) {
global $post;
if ($post && $post-> ID == 1) {
return false;
}
return $value;
});
= How to exclude a script from optimization =
1. Use the `Exclusions` tab to exclude scripts by matching src or inline content with regexp.
2. Use the `wpmeteor_exclude` filter which accepts 2 arguments: $exclude and $content. The $content variable contains either the src attribute or the text content of the script tag. Return true if you want to exclude the script. Example:
` add_filter('wpmeteor_exclude', function ($exclude, $content) {
if (preg_match('/yourscript\.js/', $content)) {
return true;
}
return $exclude;
}, null, 2);`
Alternatively, you can use the script attribute data-wpmeteor-nooptimize="true" to exclude it from optimization.
= How to adjust the delay outside 1s, 2s and Infinity =
Use the `wpmeteor-frontend-adjust-wpmeteor` filter in the following way:
add_filter('wp-meteor-frontend-adjust-wpmeteor', function ($wpmeteor, $settings) {
$wpmeteor['rdelay'] = 4000; // number of milliseconds to delay
return $wpmeteor;
}, 100, 2);
== Installation ==
1. Upload the plugin files to the "/wp-content/plugins/wp-meteor" directory, or install the plugin directly from the WordPress plugin screen.
1. Activate the plugin via the 'Plugins' screen in WordPress
1. Configure the plugin via the Settings screen - > WP Meteor
