AKISMET AntiSPAM

Hi,

I have added an Akismet subscription to some forms on a client website as per the instructions here https://docs.grabaperch.com/addons/blog/spam/ I have also added my API key to the form options. In the dashboard on the Akismet site, there is a section for "active sites" but I'm not sure how / if I am supposed to add a domain here, and if so how I go about this? All the documentation seems to be WordPress based.

Can anyone shed any light on this for me please?

Many thanks
