How do I add more sites to an existing subscription?
If you already have an existing Akismet subscription you don’t need to purchase separate subscription for additional sites. Instead you can add additional sites to your existing plan.
To do this you first need to log into your Akismet account:
Note: To access your Akismet account you need to log into your WordPress.com account. If you have an Akismet subscription than you have a WordPress.com account as one was created when the Akismet account was created. It is the same login information you use to sign into Akismet.com.
If you have forgotten your password you can reset it here:
Once you login you want to look for the “change plans” button located on the left side of the account page.
This will bring up the upgrade dialog. Here you want to choose the “Business” plan and press the “Sign Up” button.
On the next screen you want to change the number of sites you want to use Akismet with from 1 to whatever number you want. This will allow your existing Pro key to be used on additional sites.
