My CPM dropped substantially starting on July 1. I had a steady CPM throughout June. My traffic has not changed. In fact, it's increased. My traffic sources also have not changed, so I don't believe its due to my traffic quality. Has anyone else experienced this?
Don't know if you have thought about it, but by publishing your AdSense information, other than gross revenue, you are in violation of the AdSense TOS... you are begging to be banned. Your links are in your sig. Google knows who you are.
I think what big G means is not to disclose the actual numbers, but I would imagine it would be ok to discuss trends and generally if your CTR's go up or down.
It is in the AdSense Terms & Conditions. This is the relevant paragraph: "Confidentiality. You agree not to disclose Google Confidential Information without Google's prior written consent. "Google Confidential Information" includes without limitation: (a) all Google software, technology, programming, specifications, materials, guidelines and documentation relating to the Program; (b) click-through rates or other statistics relating to Site performance in the Program provided to You by Google; and (c) any other information designated in writing by Google as "Confidential" or an equivalent designation. However, You may accurately disclose the amount of Google’s gross payments to You pursuant to the Program....." The only statistic you can share is the "gross payments" from Google.
Also, each CPM is fluctuating and it depends on the CTR, the keywords (maybe the keywords changed a bit?) the market value (perhaps a few advertisers stopped advertising for that keyword?) the appearance of your ads, or a steady userbase that already knows the ad.... Just claiming that the CPM went down says NOTHING to me
I've never had a high eCPM.. its pretty much stayed all throughout though. There are a few days here and there where it drops a lot, like on weekends and such. But thats about it. Josh
