Hi All. First time on this forum. I am new at adsense. Does anyone have any idea why I am only getting about 90 cents per click earnings on credit/debt ads? I expected far more since they are high cost keywords.

Thanks for your help!

Just because they are "high cost" does NOT mean they are high payout. It maybe that that particular advertiser bid lower for the word/phrase and that was the ad that got clicked on.
