First ad = highest paying.

...has it been proven?

Hey all,

I've read a few times that the Adsense advert that is displayed first contains the highest paying advertisers/clicks.

The reason I ask is that the first Adsense block on my site has a lower CTR (around 1.5%) than the second Adsense block (around 4.5%).

I'm just wondering if this has ever been proven.

Don't think that's so. Advertisers can choose above the fold or below the fold for their ad placement. Presumably a high paying advert could therefore be placed below the fold and below a higher ad block.

What do I have to do in Adwords to influence that?

Not necessarily the highest EPC, but the top ads should be the ones that will earn the most for your site.

So, an ad paying $0.20 with a CTR of 10% should be higher in the list than one paying $1.00 with a CTR of 1%

...in theory... :-)

Ok, well I know the CTR of each Adsense block, but how would I test this theory? Is this something Google has once mentioned?

I'm just trying to work out why people think this is the case.

I can't give you step by step without creating a campaign, which I don't want to do at the moment, but when you go in to create a site targeted campaign, you have the option to pick the sites you want, and if they've enabled it, choose the spot on their site where you want your ad to appear.

Onlineben,

Google put out a couple of months ago that the way to influnce ATF / BTF was to put those exact letters as the ad block description. I now put the description in e.g. 350x250 ATF (or BTF if appropriate). At the time I did that my income jumped big time. Coincidence? Who knows, but I sure am not going to remove the ATF!

Hey all,

Just to let you know, i've changed my site around (gotta love css sometimes) so that the higher CTR ad is displayed first. Since making the changes (2 days), i've beaten all earnings records.

$100 per day will be mine if it's the last thing I do lol ;)

Karma, well done. One question though, do you think that the highest paying ad block today will be the same tomorrow? If not then the ads will possibly appear in the wrong sequence tomorrow. For my sites the highest paying ad block changes on a daily basis.

CTR = click through ratio.

More people are clicking on the ads in your second block, which are "possibly" lower paying than the first block.

Google encourages higher bids to get a higher position on web pages so the ads appear in order from highest paying to lowest. I suppose google could scramble the results after chosing which ads appear but since we can't click we can't check that out. It would be a lot of work but I can't think of a benefit.

I said "possibly" lower paying. You need to keep in mind that there are several different kinds of ads.

#1 - large banners
#2 - small banners
#3 - text links etc.

Each is seperate. If both your blocks have text links then you have double the text links and some will pay less. If you use one of type of ad you guarantee the highest paying from each block.

"do you think that the highest paying ad block today will be the same tomorrow"

I've no idea but from what I'm seeing yes (today is my best Sunday on record too).

Only Google know for sure but it makes good business sense to me.

Hoping this thread may be of use to someone, worked for me. It all helps :)

Sorry for the delay in responding to this thread.

...has it been proven?

I can confirm that in the general ad auction, our system will target the highest-paying ads to the ad unit implemented first in your HTML, working down through the auction results to fill in the rest of your ad units in order.

Presumably a high paying advert could therefore be placed below the fold and below a higher ad block.

If advertisers are targeting only specific placements, those ads will compete to show only in those spots. As a result, yes, it could turn out that those ads are higher-paying than ads at the top of the page. But keep in mind that in any case, these site-targeted ads would be bid on a CPM basis.

Does that make sense?

Does that include link units as well? I'm kinda assuming not.

Okay AdSense Rep... you said the higher paying ads are placed at the top.

So if I have a 728*90 at top and a 300*250 in the body of the content the 728*90 gets the top paying ads even though the 300*250 gets more clicks?

That sounds very unoptimised for profit and unGoogle like

I get the ATF / BTF thing. But...

the way to influnce ATF / BTF was to put those exact letters as the ad block description

What ad block description? Where?

Here's a heavily amended Adsense placement on one of my pages, the relevant line has spaced lines above and below:

google_ad_client = "bla";
google_ad_width = 300;
google_ad_height = 250;
google_ad_format = "300x250_as";
google_ad_type = "text_image";

//2007-05-05: 336 x 280 adsense ATF

google_ad_channel = "blabla";
google_color_border ="bla";
google_color_bg = "bla";
google_color_link = "bla";
google_color_text = "bla";
google_color_url = "bla";

That line starting // was put there by Google to correspond with the ad description when I set it up. Apparently the "ATF" means to the advertiser that the ad will appear Above The Fold. That's what Google told me. How they check that ad actually does appear ATF I have no idea.

Does that help any?

Thanks nomis5,

The code that Adsense provides for me has a similarly placed line which is generated automatically and merely gives the Channel ID.

//2007-07-01: channel

I'll look into it further.
