(Perhaps related: I've also noticed lately the same few spammy ads showing up on all of my blogs, though relevant to none of them.)
The only explanation I can think of is the new "Advertise on this site" option, which (as I understand it) targets the publisher rather than the website.
Any other possible explanations?
This doesn't make any difference. What hits your income is CPM Ads. The "advertise on this site" is simply a way of getting more people to site target you with CPM Ads. However, switching it off does not stop CPM Ads appearing on your site, it simply stops you advertising the facility. To stop CPM Ads appearing, you have to email Adsense support and ask them to stop CPM Ads appearing on your site.
In my particular example ... I get good traffic but my ads are very low paying due to my keyword just doesn't warrant high paying ads.
So do I email google and ask to turn off CPM ads on my site... or leave things as they are...
My bottom line is steadly dropping every month, even though my traffic is increasing...
Just can't seem to win the war against smart pricing...
To see if you have site-targeted ads, you should see if you have the SAME ad appearing on every page in a site, but not on other sites, in a format that takes over an entire adblock. Google also uses something called expanded ads, but these don't appear on every page--you'll see the same ad appearing large some times, regular size at others. Search the AdSense Help area for the official word on both these topics. If you see the same ads on multiple sites, that's probably not a site-targeted ad (unless of course they are all about the same topic).
Earnings could also be going down due to have lots of regular visitors, who have stopped clicking the ads, to changes in your traffic, to changes in ad inventory, or to advertisers reducing their bids.
You may want to try changing ad layouts, colors, numbers of blocks, etc.
So when I email google how do I word the letter, "please opt me out of CPM ads?"
Thanks for the advice. I do get a little lost because my site was created years before I ever considered adsense or any other ads on my site.. and I don't want to change the lay-out just to accommodate adsense and confuse my return visitors...
It's possible that you just get the same ads from the same advertisers because those are the people advertising in your area.
I have an old, pre-AdSense site, too, and I can tell you that there are about a dozen different companies that I see over and over. And they are not site-targeting me. They are just marketing to keywords that mean they will be on my site. But that doesn't matter, because I get a pretty steady flow of new visitors. The ads are new to them.
If you have a lot of regular visitors, then you should look into doing something to earn money from them other than AdSense. Direct advertising, affilite programs. Something should work for you.
If you have very low CTR, then perhaps opting out of CPM ads might be a bad thing. Most of those who have complained about income dropping seem to be those from sites with high CTR and/or diverse sites.
Is there anyone reading this who thinks having CPM Ads on their site has increased their income?
If you have a lot of regular visitors, then you should look into doing something to earn money from them other than AdSense.
This is pretty key here. If you have a lot of return visitors, then they will be seeing the same ads (since the content hasn't changed).
To new visitors, the ads are all new each time they visit the site :)
There are other ways to monetize sites with a high ratio of return visitor loyalty (like memberships, affiliate programs, cpm based ad networks, etc)
But they come back to my site for information in their field of interest. I tell them about new books in their field. They buy them.... It works.

Is this still so? When you pull up the "Advertise on this site" link it includes the referral domain -- not just the publisher id.
For AdWords customers, the options to target sites is also domain specific.
I can't believe that Google would do it as it would be both deceptive to the advertiser and counter-proudctive to the publisher (and ultimately worse for Google).
