I have adsense on my site and the site is ranked well in Google and according to Adsense reporting I am even showing a few clicks - but no ads display. Only public service ads.

All of my URL's are in Google and have been for months, but I only signed up for adsense 3 days ago.

Any ideas why no ads are displaying...I wrote Google but have not heard back fromt them

I have noticed this as well seemingly the last 4-5 days.
For the first time the ads are often missing 20% of the time. There is not the normal "blank space", but the code moves up as if no ad was there.

Then on a refresh maybe its there.
It appears to still be counting in impressions though, as my Clickthrough dropped 2.5% during the last 2 days.

Any reasoning would be great.

Gary:

W3C validation isn't necessary to have a good page or to be able to sucessfully run Google AdSense, however, you may have some scripting, headings, and other errors that is not allowing the bot to fully "appreciate" what content you do have on the page.

For a better feel of what I'm talking about, take a look at the W3C Detailed Validator and be sure to check the "Show Outline" option to see how your headings are being employed improperly and honestly poorly.

Some other things that *might* help:

Loose the excess js and popups.
Give your tables "id" and "summary" attributes.
Make sure you're being visited by not just the googlebot, but also the Mediapartners-Google/2.1; if not check out your robots file and rules to ensure no "stoppers" appear.

and check out these Google Resources for more information:

Good Luck and Happy Earning!

Hello WR,

Thank you for your reply. I wish I could validate, but I use a CMS and the concept of quality code is out of my control :-(

Since posting this, I have logged in from another computer and everthing works fine. However I did a test and disabled all my various protection systems and still nothing happens, so I enabled all of them again.

The only differance between one machine and another that I can see is that the other machine has a differant IP address. I called a friend in another state and they can see the ads. I called someone else and they can not see the ads.

And when I look at my Google stats they show 80% fewer impressions than my AWSTATS shows page views, and the adsense code appears on every page.

So it remains a mystery :-)

Thanks again

Gary

I saw a 50% drop in clickthrough throughout yesterday, allthough my traffic is still the same. Something must be up, but as far as I know it always returns to normal. Your location also has big impact on which ads you see.

Covered in another thread as well.
Major clickthrough and value drops for 5 days straight now.

Google recently implemented Adsense optimisation. That is, they will show only the ads that are performing best on your page. So if you have a few blocks they may drop one or even two of them completely.

They also change the number of ads shown in a block again to increase CTR. So a 728 banner block could show just the 1 ad rather than the regular 4. I've seen the whole range 1,2,3,4.

All this ain't so bad unless you have the 328 block right in your content, the best CTR position according to Google, if this gets disabled then your left witha huge empty square.

There's a bit of a debate rumbling round the Net about this. Some people have seen better CTR others have suffered badly.

Nothing to do with site code. Google isn't going to trip up over that. :)

I dont think the referred to phenom is the optimization that is going on.

Firstly they dont leave a block like a normal blank ad is, they are ogne and the code moves up. This is not the normal missing action.

Also, they are gone on many many page impressions, no ad shows, but the statistics suggest that the ad is still counting in the "impression" column even though nothing showed, this is why people are seeing the impressions pretty much the same but CTR drop very fast.

I am not sure what all this is about, but we can not be the only ones seeing it happen and so dramatically.

The other notable pattern has been the daily profit curve. Mornings seem to be only slightly down, but after 5pm to 3am EST the totals almost come to a halt, which is a new thing as well that started at the same time as all this blank ads issue.
