Revenue Shrinking Daily

I’m currently with BlackLabelAds and over the last 3 days, with the same amount of impressions the revenue has dwindled significantly.
Hypothetically (Not exact numbers but same depreciation) for 2000 views; on day 1 the revenue was 11 cents, day 2 was 6 cents and now day 3 it’s on 2 cents..whats with the blatant lack of consistency? And does it eventually evaporate into nothing?
Any experiences/advice?
