But, from last 1 month we have observed a significant dip in ad performance. I have tried using different bidding strategies (with and without maximum bid), lifetime & daily budget, best performing ads, tried new broad & specific audiences but nothing is working.
The ads reach has gone down, CPM has gone up and the results are almost negligible.
An ad set that used to reach 1000 impressions a day is now getting 80-100 impressions.
Can somebody please provide a possible reason and solution to this. Is it something at account level, or something at Campaign, Adset, or ads level?
