I don't see how using the exclusion filter can result in more targeted ads. AdSense is already crawling your pages and doing the best that it can to find targeted ads. If it's displaying ads that aren't targeted, that isn't because it doesn't want to, and it isn't because you haven't excluded general advertisers--it's because it (a) doesn't know what your page is about or (b) can't find a matching ad.

Actually for me it has now got a bit frustrating. A few days ago I added a new section on my front page that deep links to parts of my site and it has clearly picked up on a word that I happened to add - it is now serving up far too specific ads related to that. So I am getting ads of the format
small fluffy widgets
which i was getting for until the other keyword appeared, as a result my CTR has halved in the last few days.
My first instinct was to remove the 'blue' keyword, but then i just get 'pink widgets' ads, so my only real alternative now is to try banning sites that have these specific ads - which is a pain as they would of course do well on the deep pages they relate to.
Arrrgggghhhh, as if it wasn't bad enough just doing SEO, now I am doing AdSense Optimisation as well!
And I often find that some people run ads for "country" and bid much more then other for "country product" were the ad for "country product" fo course is a gadzillion times more targeted. the ad only for "countrY" is almost entirely useless.
Problem is not the adsense system, it's moronic adwords advertisers who don'T understand the concept of targeting.
I'd be great If I could post their urls to adsense so they could make recommendations for better targeting to the advertiser... everybody would win, and I'm happy to give them that service, cos it improves my adsense sales...
Hey, here is an idea.. volunteer AdSense operators to provide free consultation and optimization help to AdWords advertisers :)
They don't have to. We beenfit by earning more with higher CTR and CPM. So it's in our interest to help advertisers to produce GREAT ads that attract high CTR, and the CPM will go up naturally for the niches once the targeting is on spot and ROI is high.
Imagine, we're jsut at 100000 advertisers now, there is still so much more potential.
