The best part of the platform is it has a free version which one can use to run your own ads with credits from reading and rating ads. The free way to start is to use the ads surfing as a way to learn how to write good ad copy (headline less than 25 characters plus a message less than 60 characters) and good landing pages. Just follow what the 5 star ad writers do and build that into your free credit ads – keep doing this over and over until you are ready to go Pro. I use the paid Pro version at $19.95 a month which gives me 10 Pro ads which I can deploy without needing credits. Any credits I collect are applied to Credit ads that I run as well.
I’ve tested the Welcome Mat and Smart Bar apps as well but they didn’t produce anywhere near the conversion rate of the List Builder and Scrollbox apps (note: that doesn’t mean you shouldn’t test them on your site… it’s just that they didn’t perform that well on our site with the setup we used so we removed them so not to distract the visitor too much while we figure out new ways to test them).
