Due to my v. poor response to leaflets so far, i've been looking into this.
Powerful ways to increase response (allegedly) are to-
Put a 100% money back promise on your ads.
Make sure the title is what you offer and grabs attention (not your company name)
Have a time limited offer
explain in 'detail' why they should use you
a story is a good idea
have a call to action + make it easy to contact you.
Stilll testing these ideas, the money back one is scary though (due to tight arses, not my work)
