We recommend that the first sidebar box be your free gift/opt-in form, then the calendar sidebar box for prospects to book sample sessions. After those two (as they are the most important lead generation and lead conversion tools to have on a website) then one could list your credential logos and even a testimonial.
The ICF provides you with a specific way in which to include your credentials in your signature. You will want to check with them to confirm.
Depending on which level of accreditation you received, it would look something like this:
First Name, Last Name, PCC
