Just a thought here and it's a true story (even if the Yellow pages rep didn't believe me).
I took a leaflet headline that was converting at about two percent and added two words. The conversion jumped to EIGHT percent afterwards (in a localised market).
"Carpet and Upholstery Cleaning" became
"High Class Carpet & Upholstery Cleaning"
Like a fool (before I understood marketing) I stopped using it because I thought people would be bored of the same leaflet! You are welcome to try it
