Is WP Speed of Light 3rd party compatible?
It is, of course we can’t test with all dynamic element yet you have some options to exclude some specific URL from optimization. Feel free to send us compatibility request on our pre-sale forum or on the plugin directory support forum.
Is WP Speed of Light free?
Yes totally free of charge, fell free to install, update and even ask us questions on the WordPress plugin directory forum. We offer an optional free upgrade.
Is WP Speed of Light translated into other languages than english?
Yes, we use a translation tool accessible from the plugin setting where you can: get languages, translate, share translation with us (and get a gift for that)
Is WP Speed of Light compatible with WooCommerce?
Yes, we have added some specific code to remove specific dynamic data from cache.
How can I activate 100% of the optimization features?
In the plugin we’ve made a distinction between casual optimization like caching, Gzip compression, headers expire, query strings and advanced optimization like file group and minify.
You can activate all optimizations but, depending of your website, number and complexity of your plugins, that you remove some files or pages from this optimization to avoid problems.
All website cannot be 100% optimized even the big websites on the market like amazon.com
How can I get 100% on pagespeed test?
Some of the Google pagespeed recommendations require that you modify your plugin code, at least how the script are called, to defer some script loading for example.
At Google they’re actually smart enough not to consider a score based on criteria you can’t apply on all website BUT on loading time (reffer to the Google Search Console)
Our recommendation here:
1. Focus only on loading time, not on your score
2. Use webpagetest.org instead
3. All the tools are available to get a 100% page speed score in the plugin
Is WP Speed of Light compatible with any CDN? (Cloudflare, KeyCDN, MaxCDN)
Yes because the CDN resource call use URLs along with content inclusion and exclusion options only, so you can use any CDN service.
Is WP Speed of Light compatible with Varnish cache
Yes, there’s a specific integration in the optional pro addon, that offer the automatic Varnish cache cleaup on content save and manual cleaup.
Is WP Speed of Light compatible with Siteground SuperCacher cache
Yes, there’s a specific integration in the optional pro addon, that offer the automatic Siteground SuperCacher cache cleaup on content save and manual cleaup.
What is the image lazy loading?
Lazy Load delays loading of images in long web pages. Images outside of viewport will not be loaded before user scrolls to them. This is super efficient on pages with a large amount of images.
