Thank you for using our network, glad you like it
don't do anything flashy, keep the ad amateur with a clear call to action and targeted to your audience (the tube site?) and you will be fine. When you are purchasing from the site you choose, remember to look at the stats for that zone so you can see what the past performance has been. It will show you the CTR so choose a spot where others have gotten the highest CTR
Let me know if there is anything else we can help you with.
