How Google Ads disappeared from my site

Recently I had a problem with Google Ads on my blog. After publication a second story about Internet Explorer Bug on my site was only shown only public service ads. I was seeking the solution but all attempts was failed. Then I wrote request to Adsense Google Team. It’s described below.

Dear support team,

I have problems with ads on my site jplay.info.

Today I’ve added atricle about social bookmarks http://jplay.info/list-of-social-bookmarks-websites/
and it was showing ads just several minutes and now only PSA ads are shown.
I really dont know where is the problem.

Can you please help?
Thanks in advance,

Steps to solving the Problem

I’ve received some useful info from them immediately what I cite as an example below

Hello,

Thanks for your email regarding the public service ads (PSAs) you’re seeing. We’ve provided some information below which we hope will address your question. As you know, you can also find instant answers to some of our top questions in the AdSense Help Center at http://www.google.com/adsense/support. If you still have unresolved questions after looking through this material, please reply to this email and we’ll be happy to help you further.

PSAs may be appearing on your web pages for a number of reasons:

1. Our system may not have crawled your pages yet.

When you first place the Google code on a page, our crawlers typically index it within 30 minutes, though occasionally it may take 48 hours or longer. When you update a page, it may be 1 or 2 weeks before the changes are reflected in our index. Please note that because crawling is done automatically by our bots, we can’t control how often your pages are indexed.

2. Your site may not contain enough text-based content.

Our crawlers are unable to derive meaning from images and dynamic media such as Macromedia Flash and JavaScript. You may wish to include more complete sentences and paragraphs to assist our crawlers in gathering information about your pages and determining relevant ads to display.

3. Your site may be in an unsupported language.

At this time, we’re able to offer ad targeting and support for the languages listed here:
https://www.google.com/support/adsense/bin/answer.py?answer=9727

If you place the ad code on pages with content primarily in an unsupported language, we may show public service ads or ads in another language. Until we are able to offer this service targeted to your specific language, please remove the AdSense ad code from your site.

4. Your ad unit may be set to display image ads only.

Image ad inventory for your content may be limited at this time; if you’ve chosen not to display text ads in an ad unit, we’ll show PSAs in that unit when there are no relevant image ads available. We recommend updating your ad code to display both text and image ads.

You may wish to visit http://google.com/support/adsense/bin/answer.py?answer=10035 for other common reasons why PSAs will appear on sites. If you’re still seeing PSAs after investigating the issues noted in the link above, please reply to this email with the following details:

- Can you send a screenshot showing this problem? You can find instructions for capturing one in our Help Center: http://www.google.com/support/adsense/bin/answer.py?answer=38066 .
- What browser version are you using?
- What operating system version are you running?
- What is the exact URL that is causing you trouble?

We appreciate your patience and understanding.

Sincerely,

The Google AdSense Team

How Ads returned to my site

Since first mail I’ve been received a couple emails from them again. They said me what “Rest assured we are still looking into your issue and we will get back to you when we have more information”. And the miracle was happened, - I’ve received useful mail when after reading I’ve returned ads on my site. That’s mail:

Hi Sergey,

Thanks for your patience.

Upon further review it appears that are crawlers are targeting your pages incorrectly due to language in your META tags that is not in one of our supported languages. I recommend that you remove any text from your HTML source that is in language we currently do not support.

In addition, for us to better target Google ads to the content on your pages, you will need to use a slightly modified version of our ad code.
Please insert the following line of JavaScript in your current AdSense ad
code:

google_language = ‘en’;

Insert this code on a new line just above the line in your current code that begins:

// –>

Note that this ad code is for use only on pages with a majority of the content in English. Please let us know if you have any trouble with this code or if you have any questions.

Thanks again for your cooperation and understanding.

Sincerely,

Sean
The Google AdSense Team

The key what I’ve learned from this event

I’ve removed all attributes from <HTML> tag (about languages), unnecessary meta tags (about wordpress I’m using) and also I’ve added

google_language = ‘en’;

to adsense code and ads was immediately shown on my site!
I hope if you have some trouble this story will help you - that’s aim of my writings.
