Thread: Did you take the display order of your AdSense ADs into account?

Hello

This is public knowledge since the beginning of AdSense however I think it is still
worth to write a short article about it.

When implementing Google AdSense ADs into your website you should take the way
that Google distributes ADs to multiple units on a page into account.

The first AD Unit to appear on a Web page (in HTML code, not the visible part) always
shows the ADs that placed the highest bids. In other words, the higher an AD appears
on a page (again, in the HTML not the visible part of the page), the more that
AD is worth.

Because AD Units that are above the fold tend to get more clicks than those lower
down the page, you won't usually have to change anything to make sure that the
ADs that receive the most clicks are those that pay the most.

If your AdSense Channels however show, that an AD Unit lower down the page
receives more clicks then the AD Unit at the top you really should move that
AD Unit up in your HTML.

You don't monitor each Ad Unit with a separate Channel?
Now it is time to rethink your strategy. Read this for more Information on AdSense Channels:

How can you move an AD Unit to the first position in your HTML without changing its
visual position? The easiest way would be via CSS. To give a solution that works for
everyone is impossible because every website is different. However I wrote a modification
for vBulletin which shows how the loading order of Ads can be changed via CSS without
changing the visible location. You'll find this example here:

What is your opinion on this?

It is a mixture of CPC and CTR of each individual ads, so the ads are ordered by their eCPM.
At least that's what I always understood.

But that only reflects the value of ADs inside one AD Unit.
This means the CTR and the Quality of an AD has influence
on the price the Advertiser has to pay for a click and its
position on your website. So it is not always the case that
the first AD in your first AD Unit will earn you the most, it
could be AD two or three.

However ADs in your first AD Unit will in nearly all cases earn
you more then ADs in your second AD Unit.

After reviewing my statistics I made a very interesting discovery.

Man, this is really great. Will start implementing this now. Thanks again!!
