ADsense eCPM Trend Analysis.

Just checked my stats for September to date and compared them to other months and guess what?

eCPM down from approximately $35 CPM to $27 CPM. All else is constant and the same.

Quick analysis suggests advertisers are either paying less per click or Google is keeping a higher percentage of the click thru?

Given the immense pressure for maintaining earnings growth in light of their secondary offering, I tend to believe the second.

But even if I am wrong and the answer is actually that advertisers are paying less per click, than is this a sign that the PPC business model is maturing and growth rates are coming down to earth...finally?

You would have to have an extremely large and broad base of traffic to make a justified claim. Also, you'd have to have years worth of logs to rule out seasonal changes - and this has been an odd last month with Katrina, etc. It's virtually impossible to know.

I would not put it out of the question - but I would not make any quick assumptions either.

Advertisers are paying less per click. My average cost per click on the adwords side is now only 3 cents.

I'm seeing the opposite trend. eCPM continues to be significantly higher than it was a few months ago, and EPC is also up quite a bit.

At any given moment, some people's fortunes will be improving while other people's fortunes will be declining. That's as true with AdSense as it is in the job market, the stock market, real estate, or anything else. Never forget that AdSense is an auction-based market where publishers' earnings are based on current supply and demand for specific keywords, with conversion rates (through Smart Pricing) also having an effect.

My Epm has gone up this september. But I think it is more important to measure your month fluctuations year on year. That is, September 2004 verses September 2005. I can happily report that for the last 5 months, the year on year comparison has been favorable. Increases in traffic are turning into increases in revenue at a better than 1 to 1 ratio. For me at least, the trend of the last five months has shown great stability compared to 2003/2004 comparisons.

Quick analysis suggests advertisers are either paying less per click or Google is keeping a higher percentage of the click thru.

Or your mix of advertisers has changed. Or the type of visitor to your site has altered. Or its seasonal. There are any number of reasons for a specific sites eCPM to fluctuate.

At any given moment, some people's fortunes will be improving while other people's fortunes will be declining.

Exactly and therefore one websites fortune can’t be used as a predictor of overall trends.

Wow, that's a fantastic eCPM, regardless.
