I've had this happen a lot.
Before I explain, let me first clarify I am bidding on
domain.com
domain.co
domain.c
domain.
domain
So I can see if someone is bidding on a different variation of the URL to out bid me.
But... I've had targets from the top 500 in TV and port them to LI, run them for 4 days and get 1,000 views a day, then all the sudden like 3 a day. No idea why this happens and I can see all the variations of the target and I am not being outbid... any thoughts?
this same thing has happened to me before on LI the only way i found to fix it was to deactivate the campaign then reactivate it and my views would instantly start back up again
