Half of my pages in a domain are not showing ads today.

I wrote to Google but do not have any reply yet.

Hi,

Today when I checked, half of my pages in a domain (meme site) are not showing adsense ads today. There are no adult material on the site so I'm puzzled.

I wrote to Google but do not have any reply yet. I have heard that they only send out automatic replies so I'm a little concern.

Anyone else seen this on their sites too? What else can I do?

[piatkow]

Targetting doesn't look to good but all the ads are showing.

What else? Set to display an alternative ad or display a public information ad. If the advertisers aren't there then you won't get ads.

[jbayabas]

Is your site new? You probably have some STOP words that trigger the ads not to show. Example of stop words are as follows: murder, nude, naked, etc.

[incrediBILL]

Did you recently update your site ad layouts?

I accidentally caused 4 ads to appear on some pages once and it shut down ads on the whole page (thousands of pages) which was behavior I'd never seen before as the other time it happened the 4th ad simply didn't display.

[jbayabas]

It happened to me before when my site was new. It takes awhile for Google to properly index your site which makes most of the ads not to show up.

Totally untrue. If the old-style code is being used, then adverts will show up straight away. If the new-style code is being used, then about 10 minutes.

I have a section on my site that used link units. A while back I notice a huge drop in earnings from that channel. On further inspection, there were no link units showing, at worse. At best, a few of the pages showed them, but only one link instead of four.

I looked at that section today, and now there are none showing. I have played with that page till the cows come home. (removed hotlinking js, removed links to other pages in that section, removed other text) and nothing worked.

BUT...
When I renamed the html page to 0.html and uploaded it, the link units reappeared.

There are no obvious stop words in the URL either.

I did it to another page in the same section, and renamed that to 1.html and again, the link units appeared.

I was about to write to John (AdTrafficQuality) about this and let him know. I rechecked the 0.html 1.html etc. and now those link units are not showing. Oh well, less money for Google, less money for me.

Totally untrue.

Totally true. Google supports my theory:


Relevant ads should appear on your pages shortly after you add the code, but sometimes it can take up to 48 hours for ads to show. This is because our crawler has to visit your page and determine its content so we can serve targeted ads.

Per the OP's question: HALF of the pages are not showing ads -- it's because Google has not crawled those pages yet.

[Lame_Wolf]

it's because Google has not crawled those pages yet

.Different Bot.

NEVER seen your theory in all of the new sites i've made, or helped on. Then again, you liked those ugly arrows too.

[Lame_Wolf]

LMAO.... When do Google serve targeted adverts ? 2009?

[Lame_Wolf]

spica42, add the following code to one of the pages that does not show adverts.
You will need to alter google_ad_client = "pub-YOURPUBID"; to your own pub-id

<script type="text/javascript"><!--
google_ad_client = "pub-YOURPUBID";
google_ad_width = 250;
google_ad_height = 250;
google_ad_format = "250x250_as";
google_ad_type = "text_image";
google_ad_channel = "";
google_color_border = "FFFFFF";
google_color_bg = "FFFFFF";
google_color_link = "000000";
google_color_text = "000000";
google_color_url = "99C9FF";
//--></script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>

If it still fails to show, then it is another problem. NO bot needed for the old style code to show adverts.

This is not what the OP was on about.

And to "support" my theory...

Note: Google cannot crawl my PC.

With that info locked into your brain, please explain to me that I can create a page offline, and I will be able to see adverts?

I didn't say related adverts, and the page hasn't been uploaded to any site.

[jbayabas]

... removed  other text) and nothing worked.  

It takes up to 48 hours for the bot to recognize your changes.

 

When I renamed the html page to 0.html and uploaded it, the link units reappeared.  

Wait a few days and the ads will stop showing. Unless you made changes to the original page.

Um, what does any of this have to do with what the OP was talking about?

Back to the topic at hand which is a site suddenly not showing ads on half the pages.

There has to be a global reason IMO and perhaps it's something in the site template causing it and only half the pages have been disabled because they were the ones indexed so far.

If you have a widget or something included on every page that includes external content, such as an RSS or twitter feed, that content could be temporarily adding stop words to the site as it's being indexed and they may resolve themselves when that content changes and the pages are reindexed.

Also, I've seen ads stop when pages couldn't be indexed, have you checked Google WMTs to make sure your site is being crawled properly?

Similar problem?

Half of my pages in a domain are not showing ads today.

Wa the original title. Although it is wrong to assume anything, it is fair to say that it gives the impression that they were there yesterday but not today.

[spica42]

Thank you for the suggestions! After contacting Google they didn't get back to me but the issue seems to be fixing itself after 3-4 days.

I'm still monitoring as I'm not sure if it is totally fixed. When I first typed the OP, 40% of my pages were affected, the next day, 80%.

Today, strangely, less than 10% of my pages are affected. The site is ~ 6 months old but I placed adsense on it only for around 2 months. My adsense account is however more than 5 years old. (The issue is only present in a specific domain.)

I'll carry on monitoring and will post if the issue doesn't fix itself!

[jbayabas]

2 months is a new site. Wait a few more weeks and Adsense will start showing in ALL your pages.

[spica42]

The ads showed up fine for 2 months but suddenly disappeared a few days ago but started reappearing today..

Oh well, I guess it's more or less ok now.
