When you purchase LinkPatrol you’ll automatically be redirected to Purchase Confirmation page where you can see your LinkPatrol license key. You can see your license key at any time later by accessing your Account page.
Once you have obtained your license key you can enter it in your website’s dashboard (LinkPatrol > License).
After entering license key you will be able to activate your license:
Keep in mind that you can use LinkPatrol and all of its features without activating your license key, but if you’d like to have access to updates and support you need to have a valid license and activate it.
