Is there any way to tackle with Default ads, I have tried many companies but almost all of them have fill rate of 30 to 40% and about 50%+ impressions of my sites are wasted.
I want to know if there anyway that i implement so let say if i have three companies A,B,C
If company A have default ad it jumps to B, if B have PSa ads it jumps to C and so on.
If there is no way to do like this than u please let me know the PPC Companies Offerings Backup Tags?
Thanks in advance
