In one of my ads I made a mistake and wrote the following URLs
Display URL: [mysite.com...]
Destination URL: [mysite.com...]
as you see, destination URL has http:// twice.
this is because I didn't notice that the http:// already exists in the top drop down menu.
Please ask the adcenter team to prevent such mistakes while editing the ad and not wait for the editorial team (that missed my mistake, god knows why)
I have spent around $50 on sending traffic to www.w3.org :-[
I have also noticed that I can create an ad that has
Display URL: [mysite1.com...]
Destination URL: [mysite2.com...]
I'm sure you'll agree that this is a misleading ad, when you tell the user he is going to site a and actually is he going to site b.
This is also very easy to detect while editing the ad, there is no need to wait for the editorial team for that.
