No.

You can get overall category performance percentages, but no specific ad numbers.

Because Google doesn't really WANT publishers to be able to block low paying ads, because then they'd be stuck with a lot of cheap ad inventory and the advertisers would get pissed. (I'm a cheapskate advertiser, and I'd be pissed)

I don't try to block for earnings anymore, I just block for content (if something seems a little dicey for a family friendly site, for example) You just can't know what they're bidding - unless you're also in the same niche as an advertiser and know what you need to pay.

Would you say keeping out non related advertisers would help in anyway or otherwise?

Example: travel site. Would you ban all politics, sexual, and other non travel related sites just to keep it interesting to visitors in hope those pay more than the others?

Or doing such a thing you would be lowering your own income ?

All you can do is test it. And really think about your users and what they're doing on your site and what they are expecting.

My sites are very localized and they tend to draw a lot of political ads, but I don't want to be drawn into politics on entertainment sites, so I allow those, but I watch the ads carefully - I'm okay with candidate ads, but if issue ads start running, then I will block the political category. Sure there's probably money in them, but I just don't want 'em on my sites.

Then too, you can never be sure that what you see is what other people will see, what with personalization and all.

One problem I'm facing is blocking is only account level. (correct me if I'm wrong). I do have sites in different niches.

Let's say I want travel ads on travel sites, but travel ads on entertainment sites probably not.

I think there's no way to do that. So if you have a site about politics, another about travel. You can't block politics because that would stop also ads that match one of your sites.

Yep. I have a lot of sites; it's just the way it is.

I really think Google might help us out adding filter by site to do that. Not big deal for them. C'mon Matt!

A big facter is the country the ads are from and shown too. Many countries just don't perform well, PERIOD. The ability to block ads from showing to these countries would be a big help, because these are where the low performing ads are shown.

Matt doesn't have anything to do with it.

Matt

Sure it doesn't

But if that would come true. From who do you think you will hear it?

The AdSense blog. Matt doesn't ever comment on or announce AdSense changes.

Maybe I'm naive, but I trust Google to show the ads that are going to make the most money. I only block ads that are of questionable content. (I have a family site and don't want sexual ads, etc.)

If, for example, pharmacy ads are not relevant to my site, I *could* block them. However, I chose to trust Google. Most likely Google won't show many pharmacy ads, but if they find one that seems to get clicks then hey, why not let them show it!

Every time you block a category you're reducing your revenue potential.

There is something to this method.

I have been experimenting.

When I notice I am having at least 2 days of lower than normal CPC I look at the report of shown ads filtered to 1 day.

I block the ones I think would be low CPC type ads. You really don't know but I have noticed my CPC starts to climb to what I feel is at least average.
