"Challenge" Resource Boxes...
One of the techniques involves using the box to "pre-qualify" traffic. Instead of encouraging the click, I'm basically telling would-be tire-kickers to take a hike.
I'm telling readers up-front that the freebie train is staying in the station and that the next click is going to tell them about something they'll need to, gulp, BUY. And I'm being pretty blunt about it.
The results so far have been interesting... CTR has measurably decreased, but sales are actually up overall.
Sometimes I think we try to be a little delicate when we pre-sell... Taking off the kid gloves and warning folks that they better get their wallets out right from the get-go seems to be working.
Obviously, this isn't the right approach for every product/niche. It seems like a good fit for others, though.
