Google's Public Service Ads are served to a small, select group of charities and non-profit organisations, chosen by Google. They are sometimes displayed on websites participating in the Adsense programme.

Below is an example of a Google Public Service Ad:


You do not receive any payment if someone clicks on a Public Service Ads displayed on your site.

If you are running the Adsense programme, a public service ad may appear on your website if:

- You have changed the Adsense code (to show the ad above, I deliberately changed the client id line to the following: google_ad_client = "pub-0000")
- Google's bot has not yet crawled all the pages of your website
- The crawler has determined that the page contains certain types of "sensitive content" e.g. adult content
- Your Adsense account has not been declined (usually because your site is deemed inappropriate or non-compliant with the Adsense programme guidelines)
- Your Adsense account is still under review and has not yet been approved
- Your robots.txt file is blocking the Google Adsense crawler
- Your web page contains little or no content

For a fuller list of reasons why your site may be displaying Adsense, visit the Google Adsense Help Centre's information on this topic.
