Welcome to WebmasterWorld Guest from 188.8.131.52
I'm not sure what happend, as they worked fine yesterday, and are still displaying properly on every other page. Every time I checked today, I got the "freebie" ads.
The answer to your question would appear to be in :-
"The AdSense ad code can be inserted in the body of the web page code
wherever you want AdWords ads to be displayed. However, if we are unable to crawl or understand the pages containing the ad code, we may not be able to serve relevant ads on those pages. In such cases, we would display public service ads, for which you will not receive any earnings. "
You need to work out why they cannot spider your page
As a result the CTR is down by about 80% and AdSense revenue is down by about 95%. The Mediapartners bot continues to visit and Apache returns a 200 code for all visits. I contacted Google via their AdSense contact form Saturday, but haven't heard back.
I had an index page on another domain revert to PSAs for about 24 hours over the weekend, then get its targeted ads back yesterday.
Did the mediapartners crawl not populate the index correctly? Has Google implemented some new eligibility criterion that is excluding certain directories? All I can do is stab at random ideas. So many folks raved about Google's responsiveness when AdSense launched. It's apparent silence now both puzzles and concerns me.
I finally heard back from Google about 48 hours after contacting them via their AdSense contact form. Unfortunately they didn't give a clear explanation and the explanation they did give is rather confusing.
"...the pages in question contains negative content."
I followed up to ask what they mean by negative content and for some details so I can take action if necessary. My site has thousands of pages, most of which previously had paid AdSense ads so I'm not sure which pages they're referring to.
The ads appearing on this page are non-profit ads because we do not have any paid-for ads to serve on this page.
Again, I don't know what page(s) they're referring to. I didn't mention specific pages in my initial communication with Google. My two top entry pages and hundreds of other pages were showing properly targeted paid ads for more than 2 weeks. Then a few days ago most (maybe 90%) of those pages began showing public service ads. Those that are still showing paid ads are still showing the ads from many of the same advertisers as before so their explanation doesn't seem valid.
Malibucreek, if you or any others experiencing the same problem are interested please contact me privately. I hope to hear back from Google about my second reply soon, but it couldn't hurt for me to mention details about others having similar problems. Let's coordinate our efforts and work with Google to figure out what the problem is and solve it.
My impressions are down by 50% now because of that. Other pages seemed OK.
I did a little trick that may revive the mediabot for this page.
I chaged the file name to upper case (i.e. from widgets.htm to WIDGETS.htm) and updated all the links with new(?) file name.
It is currently showing the correct one after I have done this. I will have to wait a while if this increase the impressions again.
BTW, the public ads are not counted as impressions.

itisgene, that may be true, but what are you basing that on? Based on comparisons of AdSense impressions to Apache log page views I thought that was the case until recently and now I'm not so sure.
I found for many pages in my nich there less then a dozend advertisers... if jsut a few of them switch off content ads it could happen quickly that there are no viable advertisers for that page.
If this happens more often they have to give us some chance to add our own default ads, or at least shrink the space used and let us display our own ads.
I am comparing the impressions from my stats with the Adsense impressions. Today it dropped dramatically even if the site stats shows normal page views. The entry page I mentioned gets more than 50% of my traffic.
So, i can tell the difference.
And also if you don't get paid for it, you don't have to know the stats. Right?
Same for Google, I think.
"We have found that while our content targeting algorithms generally work very well, there are a small number of pages where poorly targeted or non-paying ads will show up."
They asked for more details on what kind of targeted ads I had seen, when they ran and when they stopped. Haven't heard back yet -- I'll let y'all know if I hear something tomorrow.
But, from following the board, I gonna read between the lines that late last week, Google did something to the algorithm in attempt to cut down on inappropriate or poorly targeted ads. And that resulted in pages that Google perceives to be about multiple topics, or more generic content, now getting the PSAs rather than scattershot ads.
That said, the ads I got on my page in question were quite well targeted. But they may have been so targeted that no one clicked on them, which I assume also will throw a page into the PSA dungeon.
I also noticed that Google's first Case Study site is showing them on home page.
It's a disturbing trend, as I have no idea if or when the normal ads will return. I've removed competing ads, as per Google's TOS, and have given AdSense prime real estate on the strength of last week's strong beginning. With the public service ads running, I'm losing revenue as we speak.
The only way I have found to get those to go away are messing with the url.
http //www.mysite.tld/page.php <- will not work
The following all work:
Why? I have no idea, but it freaked the crap out of me at first, as I stood to lose my shirt. I strongly, strongly think it's a bug.
I wouldn't mind this, if only they had a broader range of public service ads - some Australian ones, in particular.
I sent Google a question regarding these and they send me verbatim FAQ.. They clearly didn't read the part about the page being up now for a couple weeks.
It does seem that it's more common on pages that are heavier with outbound links.
PS: My per click earnings have gone down over 50% over last few weeks.
