WordPress is a Content Management System, or CMS, that allows you to build and manage your website with just your browser.
Stay away from plugins when you can because they slow down your website. Most likely your theme comes with the functionality you are looking for.
Speed tests are helpful when doing a speed audit. This can be for a website you have created, or one you are taking over. If you want to speed up a website after an audit, give an estimated price to your client.
