What is Caching and how does Solid Speed leverage it ❓ There are several different types of caching Solid Performance focuses exclusively on page caching, grabbing the HTML of your WordPress URLs and storing that in a secure directory. Then, when your visitors arrive at your site, the browser doesn’t need to run through PHP or hit your database again, it just serves up the static HTML, CSS, and JS files fast and simply. How Page Caching Benefits Your Website Performance 🚀 As soon as you activate Solid Performance, your site will get an immediate boost. You’ll see benefits like these: 🚀 Improved site performance (content delivery speed) 🚀 Reduced drag on server load 🚀 Measurable, quantifiable stats: lower bounce rates and higher conversion rates When a site developer or manager is able to improve site performance for a client (for example), they are able to provide improved SEO results and meet a widely accepted expectation that well-run sites do not have slow download or content delivery times.

There are several ways to install and activate Solid Performance for your website. Here are two of them: Install Solid Performance via the “Add Plugins” screen To install and activate Solid Performance via your WordPress admin area, navigate to “Plugins > Add New Plugin”. On that screen, go to the search field on the far right top of the screen and type in “Solid Performance” and hit Enter. The “Solid Performance” plugin should be your first result. In the “Solid Performance” plugin card, click on the “Install Now” button. You’ll see the button change to “Installing”, then it will switch to say “Activate”, click “Activate”. At that point, Solid Performance is active on your website. Lastly, navigate to the Dashboard, then navigate to “Settings > Solid Performance” and toggle the option to “Enable Page Cache”. Now your site is SOLID with Solid Performance. Install Solid Performance via SFTP

1. Navigate to wordpress.org/plugins/solid-performance and near the top right of the screen, click on “Download.” That will download the solid-performance.zip file.
2. Unzip the file locally on your computer. That should give you a folder called “solid-performance” with all the plugin files. If there is a sub-folder in that folder also called “solid-performance” then we’ll use the sub-folder.
3. Upload the whole “solid-performance” sub-folder to the /wp-content/plugins/ directory
4. Navigate to your WordPress admin area, and then to “Plugins”. You’ll see “Solid Performance” in your list of plugins, but it will not be activated. Click on the “Activate” link.
