I read somewhere, that one has better clickthrough rates then the other. However, I cannot find this research anywhere now. Does anyone have it bookmarked somewhere or can point me in right direction?
I recently read an article about that too (couldnt find the link though). It said Hot Deals works better than Special Offers .. UNLESS you customize it Hot Deals For (mysite.com) users Special Offers for (mysite.com) users <-- works better
Have you not thought of split testing them, 1 web page hot deals the other specail offers using Adwords, same key words - this will tell you which is best!
I would split-test it. Even if there is some study that indicates which is best, what works for others may not work for you.
