Is there a risk to submitting the same ad to be reviewed again if it was initially rejected? I'd like to resubmit a few, but am concerned that this pisses off traffic sources and is seen as some kind of spam/annoyance.
As to why I'm considering this, Leadbolt rejected a few of my ads. While some of the rejections were reasonable, others simply didn't match the stated reason and show clear subjectivity/bias.
do it all the time
really depends I guess. most of the time, it got rejected for some stupid reason or is borderline against the rules. if so, I just re-submit.
I doubt the ad networks pay attention too much on who "spams" by resubmitting, but I could be wrong.
^ same
Unless they call me on some blatant violation that I hadn't considered, I'll usually resubmit 2-3 times before giving up on most traffic sources.
FB is the exception because of their auto-approval/rejection. If something gets rejected there you have to changed it a little bit before resubmitting most of the time.
Assuming I don't know that there was a good reason for my ad to be rejected, I'll normally stick anything that gets rejected back in the approval queue just by default. Approvals mistakes happen so often I figure (and know, in a few cases) that traffic sources are fairly forgiving of it.
Exception, as you say, is Facebook.
