Three AdSense units

Not all showing up

[TampaLou]

I've been running into a problem with the new three AdSense units deal where the system will seem to not allow all three to be shown. Example: I have a page with information on my personal account that had a 160 skyscraper. I tried adding two more 160 skyscrapers to run below it, but they didn't show up.

Another case (separate account -- this is with the business that I work for): We had a 120 skyscraper on a page. I added a 468x60 and that worked; I added a second 468 and at first it worked, but then it quit acknowledging the second 468 ad (even though the preview tool showed that there were plenty of targeted ads that it should fit w/o problem). I then eliminated the second 468 and instead went with a 180x150 in the left corner, and that worked but it seemed to knock out the functionality of my 468 banner.

I understand that the system is new and that Google may still be working out the bugs, but I wonder if I'm alone on this, if it's something I may be doing wrong (or misunderstanding), or what the deal is here.

If you read the AdSense FAQ, or prior posts on the subject here, you will learn that Google will fill one, two, or three units depending upon its inventory. And it will fill them in the order it finds them in your html code.

Perhaps I wasn't clear on the point that the Google AdSense preview tool reveals that there is plenty of inventory to fill the slots.

There is obviously a disconnect between the Adsense Preview tool and the reality of G filling up all the 3 ad formats. It may be a temporary glitch, or maybe not. Unfortunately, we don't earn from the ads shown in the Preview tool - we earn from the ads shown on our site. So better make use of the collapsible script in order to avoid showing a big blank spot in your page.

We are also in a category where there are supposed to be an abundance of ads, but we have many pages where only one ad format is filled and the other 2 ad formats are not shown. You may also want to check out this thread:

I've put a second ad block on my homepage, so far just firing blanks.

It seems axiomatic that the mere fact that Google has inventory available does not mean that they will choose to exhaust it on your site, rather than spreding it across an array of AdSense publishers, even if it would mean "more profit for you".

[alika]

Most likely the reason why they introduced the collapsible script simultaneously, because they know that they may not be able to fill the additional ad spots for many web pages.

TampaLou,

I have the same problem. After placing second unit to my site instead of PSA's ads it just show me blank place... Really strange.
I have putted it down of the page to see what will happen.

Now i'im getting PSA's on the main block for the first time ever, and a blank for the second block. I must remove it until things settle down.

There seem to continue to be problems with the multiple ad presentation, though when it works it seems quite effective.

My earnings yesterday went to 3X what they had been on a daily average for the past month, I think in no small part because of the ads (and that's even with the problems that some of my pages had with them).

The system seems to really dislike the three ad approach, so I've backed off on that for the moment; the two-ad deal isn't perfect but seems to work better (at least for the sites where there are ample ads that appear available from the preview tool).
