Don’t Block Low Paying Ads

Trying to increase earning by using the AdSense Competitive Ad Filter to block low paying ads doesn’t make sense. Google’s algorithms automatically display the ads that will make you the most money. This is in Google’s best interest because the more money you make, the more money Google makes. Trying to outperform Google’s algorithm is next to impossible. Google has much more information on the ads themselves and what works and what doesn’t work.

Let’s say you do some research with a click tracking script and you manage to identify an ad with a low CPC and you block the URL of the ad from our site. What could be wrong with that? Lots:

  • What if this ad has a fantastic CTR? If this ad pays half of the other ads on your site put has a 3x better CTR, it would have made you more money than other ads.
  • What if other ads from the same URL have a better CPC? Advertisers often have several campaigns going, each with different ads and CPCs, but the same URL. You could risk blocking a higher paying ad without knowing it.
  • What if the advertisers change the bid price of an ad? Advertisers often change the bid price of an ad. They may find an ad was more effective than they thought so they are willing to pay more for it.
  • What if there is a drop in ad inventory? Having blocked URLs could cause you to start displaying PSAs.

    We should be happy for every cent we earn so blocking low paying ads is a very bad idea.

    Google’s Inside AdSense Blog just had something to say about this on a post from Sept 24th

    “Tip 2: Don’t believe the myth about blocking ‘low-paying advertisers’

    Our auction system automatically selects the best performing ads for each page to help you earn the most possible money. This is especially true with our new expanded text ads. By filtering ads you think are low paying, you could actually be cutting out the most optimized ads and decreasing your revenue potential. Each ad that is filtered is one less bid in the auction, lowering the price for the winning ad on your site. You benefit most when there is a larger pool of advertisers competing for a place on your site. Additionally, when we calculate the auction, we take ad clickthrough rates (CTR) into account – an ad with a $0.25 cost-per-click (CPC) with a 5% CTR is more valuable than an ad with a $1.00 CPC but a 0.1% CTR.”

    What about blocking “crappy” search ads?

    mhhfive,

    That site seems to list ads based on their opinion that the sites are selling products or services that are questionable in terms of business practices. This has nothing to do with the earning that one would get from these ads.

    If you want to ban ads from your site on ethical grounds you are welcome to do so. I think this is closer to what Google had in mind as the proper use for the ad filter.

    how about if CPC only 0.01 $ ??? should I block it?

    jopz,

    What if that $0.01 ad has a 20% CTR when the rest of your $0.02 ads have a 1% CTR. Remove that $0.01 ad could be a very bad thing to do.

    Hi all,

    This was a great usefull post. It seems the propaganda of blocking lower rate ad is started by people who want to sell lists about these low rate domains and make some money out of people trying to make money of adsense. Its a rip out watch out :) .

    Do you block CPM bidding?
    Though site targeting is useful as an Adwords avertiser, it sucks when you’re on the other side:)

    I don’t block CPM bidding. For most of my sites, the CPM rates are only slightly lower than the CPC rates, for some channels it does much better.

    Google will show the highest payong ads,it’s in their advantage. Filtering ads is a bad idea. Better go now and empty your competitive filter :)

    I also don’t block low paying ads. As you said, if I get more money, Google get more and showing the right ads is for Google priority No1.
