The Competitive Ad Filter

The competitive ad filter is one of them great features of the adsense control panel, it enables you to filter out the ads that don't provide any value to people that click off your site on to someone elses, these no value sites are what are termed as "made for adsense sites" that only hold ads and nothing much else, because they pay per click on the adwords program there is more of a chance that adsense ads for their sites appear on others all around the internet as sponsored listings.

Ads that have the url tiny url.com or shorturl.com are the usual suspects of this greedy practice for earning through adsense, other sites may be good sites but are not really relevant,so some of these you need to filter out by adding the urls to these sites as filters, if you have some sizeable traffic, then this could boost your adsense earnings.

The made for adsense sites are sort of the type of sites that almost intercept your potential earnings and you'll notice these types in your account as they are the ones that pay a few cents - filter the garbage out today!

Visiting The Adsense Help Center Is Always The Best Start

Mostly when I first joined the adsense site I found the adsense help center to be the most helpful part of the adsense experience and it gave some good pointers as to what works best according to other publishers who have been doing the adsense income earning thing for awhile.

And the adsense help forum is another source of good information, you'll have to sign in because the forum is located on google groups.

I always advise help you can actually find on the site itself first before you go off and try elsewhere, as something may have been answered already on the adsense help sections, but there are other great adsense tip sites out there.
