If a site isn't supported yet, click Request a site on the Monitors page and paste the URL. We'll first check whether it already works. If it does, you'll be taken straight into creating a monitor. If it's genuinely new, we add it to our list. You'll hear from us when we look at it and when it's added, and if we need to know which products you're after, we'll ask on your request. You can reply there, and find every request on Your reports and requests.
On a phone the Request a site button is only on the Monitors page while you have no monitors. Paste the shop's link into the box at the top of the page instead. If we can't read it, an Ask us to add button appears underneath, and one press sends us the request.
