Re: For those with REW Template sites...
Liane - REW templates (or any website) by itself will not generate you any leads - leads come from traffic, and traffic comes from lots of places - (but with REW users it's usually organic SERPS or PPC)
So without working very hard on SEO, or having a decent PPC budget your REW site (or any site) won't do anything for you other than look nice. (So yes there is lots you have to do - which means either time or money)
What I will tell you, is that from REW template stats I have observed with traffic, an IDX (registration enabled) you should be running between 3-5% conversion on organic and 6-10% on PPC is properly setup.
So that means for 100 absolute unique visitors, you would get between 3-10 leads depending on SERP position, competition, PPC vs organic etc.
