Yellow: Satisfactory. You could make some further improvements to this item.
I have few sites using Google AdSense to make cents (yes, cents only). On recent update of Google AdSense, a new module called Scorecard displayed on my dashboard.
In item Revenue optimization > Text and image ads enabled , it is marked as Yellow. But I have already enabled Text and Image ads in all my sites. Why does it still having Yellow instead of Green? Is it a bug of Google AdSense Scorecard ?
