Tested 2 headlines for similar products on Togoparts, but both with the same body copy. Based on the tracking I did, people clicked the link in the copy:
– 11 times on “An Inexpensive Power Meter You’ll Love”
– 3 times on “The Fuss-Free Power Meter You’ll Love”
Which might mean that something which seems cheaper, appeals better than something that seems to give less trouble. Ha!
