OK. Here's a good one.
On one of my pages, I get 2 Custom Channel reports, daily,
even though the OLD channel (and ad) has long since been removed many months ago.
(Daily relative numbers, last 30 days) The page content is IDENTICAL, except for the ad.
OLD channel - a 300x250 ad (NO LONGER SERVED)
Impressions - 273
Clicks - 14
Impression RPM - $31.21
PPC - $0.61
Earnings - $8.52
NEW channel - a Responsive ad
Impressions - 1,189
Clicks - 59
Impression RPM - $12.61
PPC - $0.25
Earnings - $14.99
I would LOVE to hear an explanation for this.
1. WHO is serving my page with OLD CODE?
2. WHY does the new page/new responsive ad pay LESS THAN ONE HALF the old page/old 300x250 ad?
3. SHOULD I change the ad back to a hard-wired 300x250?
I find the responsive ads to be very flaky, inconsistent,
undesired ad sizes (vertical collapse to minimum), etc., etc. No control.
