Nice dude! Although I'm more used to making sales then when I first started out,I still wig out and dance around like a total idiot every time I make a new one (yeah,like you guy's don't....grow up!
).
If you can,see what sales text or banner the paying surfer clicked on to hit your sponsor,then try to recreate or build on that ad.This will help build your sales writing and ad layout skills and help you understand what works and what doesn't.I could be wrong but I know doing this helped me.Obviously though,if you just got lucky on a horrible ad,don't do this.
Anyhow,keep it up!
