When I first used the Site Preferences Module I was excited with the extra freedom and control it gives WebWiz@rd users. Aside from controlling form auto response messages and "send-to" email addresses, it has some extra features to help with Search Engine Optimization.
My favourite thing about this module:
I really like that it gives clients the freedom to update their Google Analytics code on their site as well as the power to assign default page keywords and add a page title suffix to the site. These are all great features to help with their Search Engine Optimization.
