Adsense bringing back irrelevant ads all of a sudden
irrelevant ads

 5:55 pm on May 7, 2006 (gmt 0)

The ads on my site have typically been relevant to the content of my pages, but all of a sudden (2 days ago), I noticed that there were no ads appearing on my 160x600 skyscraper ad.

Finally, yesterday, I reconfigured the content layout a bit and noticed that ads were once again showing up on the skyscraper, but now, they have absolutely nothing to do with my website.

I thought that this could be due to the advertisers being at the end of their ad cycle, but when I visited another website with content similar to mine, I see the ads that I used to get on their site!

Does anyone know what's going on? How do I get my relevant ads back?

Thanks in advance,

I have site wih a page covering fraud in greyhound racing, and I saw adverts there for sites that were way off topic.

First time ive noticed this.

Oh and I though it was just me. My ctr was going down and I didn,t know why thats because I disable google ads on my machine, but when I check in another pc the ads are way off base, I havent seen this in along time I hope it gets back to normal soon :)

I have also seen poor targeting and lower ecpm.

I use a secondary ad market when google's relevancy goes down on a page for more than a week.

I select the ad instead of google and I am paid on conversions. Sometimes it is a big winner, sometimes it is a flatliner.

Waiting for someone to place a relevant google adwords ad, doesn't make me any income, so it is nice and profitable to have a second option.

Major relevancy problem here too, started 10 days ago.

It's not a niche problem, as my site has more than 110 different subjects.

Also it's not a SEO problem. Many pages that rank first position on a search for a determinate keyword only show irrelevant ads to the respective keyword.

Of course click rate is the lowest ever.


 5:24 am on May 9, 2006 (gmt 0)

Seems like I'm not the only one having this issue. How does this problem get resolved, via an e-mail to Google, or by just "waiting it out?"

I was going to start a similar thread until I found this one.

I'm getting ads for El Salvador and somewhere called Burgos on pages that are in English, are marked as lang="en", and contain no foreign words or characters. And this is happening on a section of my site that's about a canal holiday.

What's weird is, it only seems to happen on the large photograph pages, not the medium-size photo pages.

Google's also reportedly dropped a lot of pages from its search index recently, and one report suggested that their servers were short of disk space. (It also suggested that a cynic might think that it suits Google to push big sites onto AdWords to get back their traffic.) For such a market leader, Google does seem to have dropped the ball quite a bit recently.

Worse I've seen - ever. Take a deep breath and check your sites ("Find web pages that link to www.example.com").

I've been corresponding directly with an Adsense rep about the poor targetting on a substantial portion of our pages. It's clear that they are aware of the problem, but can't offer much in the way of fixes. The rep did mention that ad inventory could be the problem, as in, too many publishers competing for ads in a given space with not enough advertisers.

While I was initially skeptical, it could very well be that in my oldest and most authoritative niche, the number of competing sites running Adsense has simply swamped the advertising budgets. Keep in mind it doesn't matter whether or not your competititors have quality sites, as long as they are getting traffic from somewhere and displaying ads. An indication of this may be when the ads displayed slowly become more general and lower paying, indicating that the publishers in a specific niche have proliferated beyond the demand.

For example, say our site was about rebulding Indian Motorcycle motors. As more and more sites came on line, some of them scraping content from our site and our natural competitors, and all these new sites focused like a laser on "rebuliding Indian Motorcycle motors" because that's the phrase the scraped and the domain name they registered some variation on. The legit advertisers who were paying good money because they are actually selling pricey parts and rebuild kits would now either run through their budgets quicker or be able to bid less on Adwords. As a result, our site and our natural competitors who also run Adsense would slowly see our ads becoming less targeted over time, to include anything refering to Indian Motorcycles, mortorcycles in general, and in the worst case, motor rebuilds in general. By the time the ads drop down around to a penny or less for rebuilding John Deere tractors, nobody is clicking and the site is losing status with Adsense as well. Our only choice seems to be to keep removing Adsense from pages when the ads lose relevency, and hope for the best.

Even in niches much larger than rebuilding Indian Motorcycle motors, the same effect could take place. There are far more natural competitors in broader niches to start with, it's far easier from somebody to scrape together new sites, and it's more likely to attract their attention to start with. I suspect that all we can do is continue publishing the highest quality content possible, don't run Adsense on pages where it doesn't pay, and hope that at some point in the future Google will either provide new targetting options for publishers or develop a human assigned quality quotient for sites. This would allow them to devalue the scrapers and content provided by key phrase writers in sweat shops who've never seen an Indian Motorcycle, much less know a spanner from mouse.

My site has been online for over eight years. Out of over eighty article pages (a figure which does not include index pages, etc), Google is currently listing sixteen.

I don't know whether Google is short of space, or whether my pages have been heuristically deemed irrelevant, but it's a pretty dire situation from my point of view. Luckily, MSN and Yahoo! seem to value my site quite a lot. I'm slowly being won over by the Yahoo! search results. (Yahoo! lists 215 pages from my site, and MSN inexplicably claims to list 1,251 pages from my site while only featuring 250.)

As for the adscape being too large to support a fixed number of advertisers, I think you're probably right. But that surely can't be Google's excuse for my pages about Birmingham Canal Navigations displaying foreign-language ads about Burgos and El Salvador.

Google need to up their game, IMHO.


 7:00 pm on May 9, 2006 (gmt 0)

My site has seen eCPM less than 25% of typical within the past week or so. Really sad.

I am seriously considering implimenting my Yahoo Ads that I was offered to join recently. My genre is financial/investing research and typically pays high eCPM. This AdSense slipup is seriously hurting our business.

AdSense cancelled us about 2 months ago. We wrote emails a few times over a week and they reinstated us. The revenues have been nice since then, but recent sinking of eCPMs sucks.

There appears to be a problem with AdSense software or something here. Many of the comments are from different genres. I doubt that all the advertising subject areas are going to drop spending, or add that much available inventory all at the same time.

Something has changed on Googles end.

But that surely can't be Google's excuse for my pages about Birmingham Canal Navigations displaying foreign-language ads about Burgos and El Salvador.

If you are the #2 result in Google for your key phrase, the fact that your lead page seems to be gone when I click the link may solve part of the mystery. Are you sure your server didn't lose some pages?


 9:08 pm on May 9, 2006 (gmt 0)

I am not sure why but i have noticed that happens time to time


 10:54 pm on May 9, 2006 (gmt 0)

I'm sorry, content_ed, but I don't understand what you mean.

I don't think my page comes up in second position in Google for any keywords (maybe third or fourth position for some key phrases). And when you say the page is gone when you click the link, do you mean that clicking a link to my site on a Google result page returns a 404? Can you private message me with the specific URL that gives you that problem?

(This would be easier if I could state the URL of my site, but I understand why this forum wants to keep the boards clear of site-plugging messages.)


 11:10 pm on May 9, 2006 (gmt 0)

(Longtime lurker, 1st time poster :))

Totally irrelevant ads on my homepage - in a niche that has many many advertisers. Typically he irrelevatn ads are for Sth American Hotels.

What's more, the 2nd block of ads on that page just is not showing at all.

Started maybe 2 days ago from what I could see. But when i then refresh thepage, normal ads show correctly again.



 12:13 am on May 10, 2006 (gmt 0)


Here is an email that I just sent to Google. I'll keep you advised if there is a substantive response.

Dear AdSense,

In the past week, I have noticed that my eCPM has taken worse of a dive than usual. Many less ads are being displayed per page shown from my web server. This is new and significant.

Please see comments of other webmasters on the subject: [webmasterworld.com...]

I am willing to provide server information to you if it would help substantiate the problem. The forum above and my contact with other webmasters tells me that this is not simply an online advertiser issue with too much inventory or lower budgets since it extends across all advertising genres.

I understand that your system is proprietary and that you are not likely to be able to share the nature of any problem, but please do not take this as routine.

Perhaps you could put something in your AdSense blog and/or emails AdSense users to explain what happened and that it is being worked out?

Thank you for your attention and support.



 1:34 am on May 10, 2006 (gmt 0)

I have just noticed the same thing. Totally irelevant ads in my square blocks and psa's where the skyscrapers reside.


 4:07 pm on May 10, 2006 (gmt 0)

AirLifter2 - I'd love to hear what Google replies back with. My site got some coverage in the local newspaper today and this lost ad revenue is really starting to hurt


 4:33 pm on May 10, 2006 (gmt 0)

I'm seeing the same thing on my educational site. Lots of ads for ring tones by the same three advertisers. Placing the urls into the competitive ad filter has had no effect. Has anyone else tried blocking irrelevant ads? Any luck?


 4:35 pm on May 10, 2006 (gmt 0)

I checked today some pages because unusual low CRT.

I surfed in Austria, but there was an add only suitable for somebody living in Zürich Switzerland.

Total irrelevant.


 5:13 pm on May 10, 2006 (gmt 0)

I'm getting a lot of mortgage and work-at-home ads today. Needless to say clicks are way down.


 5:14 pm on May 10, 2006 (gmt 0)

Same here, irrelevant ads are served.


 5:33 pm on May 10, 2006 (gmt 0)

Add me to the club!, add relevance has been terrible the last couple of days, and today ctr and ecpm has been especially low.


 6:28 pm on May 10, 2006 (gmt 0)


You ALL need to write adsense so they know that this is not just one simple situation, but that many are being affected. As we know, they tend to reply with "canned" responses and tell us to trust them. Well, we see how that is working now.

PLEASE write them at: adsense-support@google.com

We must let them know if force so that they will fully realize the problem and fix it.


 6:51 pm on May 10, 2006 (gmt 0)

I got a canned response:

I am responding with.....

Google AdSense Team,

Thank you for your response. However, I do not feel that AdSense properly identified or responded to the problem. Obviously something has recently changed in your system.

We have noticed a significant number of AdSense clients getting ads that are not relevant as well as eCPMs, CTRs, etc. changing. This is across all genres.

I appreciate you bringing to my attention the references that you have posted. However, having a moderate computer programming set of skills and experience myself, the current situation does not fall within the scope of the explination you gave.

Quite simply, to have so many websites experience very similar problems of such significant variation from the historical mean, dictates logically that it is a problem with the overall serving programming. Quite obviously, something has changed with your system recently.

I stress my point to assist the Google AdSense team in beccommming aware of, and analyzing a problem that your typical system monitoring metrics are not programmed to detect. I do hope that your team is able to further consider my concerns and evaluate the problem in a new light.

Let us all hope that this information proves helpful. Thank you again for your time, consideration, and support.

That's about all I ever get. If I respond and point out the canned response wasn't accurated, I just get a different canned response.


 1:39 am on May 11, 2006 (gmt 0)

I already got a response back from AdSense. It appears that they took me a bit more seriously according to the comments.

After getting this, I logged on and saw several clicks with a very nice eCPM. Perhaps someone did go back through my blog and figured out an adjustment that needed to be made to credit conversions, etc.? We're in the process on major SEO implementation along with regular press releases. We will keep an eye on this apparent "early" correction of our reporting.

Airlifter, are you a premium publisher?

Total irrelevant.

And even more annoying, this was the one and only ad in a 300x250 ad block
