Why am I getting Public Service Ads (PSA)?

Adsense Public Service Ads - SEO Wondering why sometime your ads turn out to be Public Service Ads on your site? Here is a long and detailed explantation from Google. There can be many reasons why a website may display less targeted ads or public service ads. Below is a list of the most common issues. Read on to find out more what Google says..

  • Our system has not yet crawled all the pages of your website.
    Our crawler needs more time. If Google has not previously crawled your site, it may take up to 48 hours or more before our crawlers gather content from that page. In the meantime, the ads you see may be public service ads or ads that are only slightly relevant. The relevance will increase over time.
    Our crawler cannot reach your site. If our crawler is not able to access your page, we will provide you with an error message on the Site Diagnostics page of your account. For more details on these errors and how to resolve them, visit our Site Diagnostics entry.
  • Your page may contain sensitive content for which relevant paying ads will not be displayed.
    Our system has certain filters in place to protect our advertisers from advertising on pages that could be construed as potentially negative, non-family safe or even offensive. Although, the nature of your content may not fit into any of these categories, at times the emphasis of some sensitive subject matters on a page can flag our servers to deliver public service ads to a page.
  • Your account may be disapproved or awaiting review.
    To determine the status of your application, please try to log in at www.google.com/adsense using the email address and password you submitted with your application.

    • If you see a message stating: Account Not Active: An AdSense account does not exist for this login, as it is associated with an unapproved application, search your email to find the disapproval or account closure message we sent you for more information.
    • If you have applied to AdSense through another website, such as Blogger, you may be displaying ads even though your application is not reviewed or has been disapproved.
      • If you see a message stating Account Not Active: An AdSense account does not exist for this login, as your application is currently in review., please wait 2-3 days until we review your application and send you a reply.
      • If you see another message or form, search your email to find the disapproval message we sent you for more information.
    • If you successfully log into your account, this reason does not apply to you.
  • Your site has restricted access using a robots.txt exclusion.
    If your site is using a robots.txt file, the AdSense crawler may be blocked from crawling your web pages. Therefore, we may not be able to serve you the most relevant ads based on the content of your website. On pages where we are unable to crawl or understand the content of a page, public service ads may be displayed, for which you will not receive any earnings.If you would like to grant our crawler access to your pages, you can do so without granting permission to any other bots. Simply add the following two lines to the top of your robots.txt file:User-agent: Mediapartners-Google*
    Disallow:This change will allow our bot to crawl the content of your site and provide you with the most relevant Google ads for your pages.

  • Your website is using session IDs in the URL.
    If your web pages use session IDs, you may not receive targeted ads on those pages. Since this session ID and therefore the URL, changes every time that a different user views a page, the URL will not be in the index and will be queued to be crawled. Once the URL is crawled, however, the session will most likely have expired. This means that pages seen by the users are never in the index. You will need to remove the session IDs in order to display targeted ads.
  • Your website is using frames.
    Google AdSense crawlers are unable to match ads to your web page content when the AdSense ad code is placed in a frame separate from the primary content of your website. It is important to place the ad code in the same frame as the content of your web pages in order to serve ads targeted to your web page content.
  • Your ad unit is set to display image ads only.
    Image ad inventory for your content may be limited at this time; if you have chosen not to display text ads in an ad unit, we will show PSAs in that unit when there are no relevant image ads available. To avoid showing PSA’s, we recommend updating your preferences to show both text and image ads or implementing an alternate ad.
  • Your web page may not contain enough content.
    There may not be enough information on your site for our crawlers to determine the content of your pages. Therefore, we could be having difficulty identifying relevant ads to show on your pages. Please note that our crawlers are unable to derive meaning from:* audio and video files (.wma, .mpeg, .mov)
    * mp3 files (.mp3)
    * images (.jpeg, .bmp)
    * Macromedia Flash movies
    * Java AppletsIn such cases, we recommend that you include content other than the above files on your website, to assist our crawlers in gathering information about your site in order to display relevant ads.
  • The AdSense ad code was placed within an IFRAME.
    Our targeting technology is not optimised to serve ads within a separate IFRAME. If you placed the AdSense code in a separate IFRAME, your site may display less targeted ads or public service ads. For better results, please implement our ad code directly into the source of your web page. Once you make these changes, relevant ads may not appear immediately. Until we are able to crawl again your site, which may take up to 48 hours or more, your page may continue to display untargeted or public service ads.
  • Your web pages are behind a login.
    At this time, pages that require a login cannot be easily visited by our crawlers. Additionally, since these types of pages are not easily visited for approval and it is difficult for our AdSense specialists to verify that pages protected by a login follow Google AdSense policies, we are unable to offer support for these pages.
  • There are too many URLs added to your account filter list.
    At times, if you add too many URLs to your filter list, we may no longer have other ads available to target to your content. As a result, you may begin to see less relevant or public service ads on your web pages.
  • Your site content is primarily in an unsupported language.
    If the AdSense code is placed on pages with content primarily in an unsupported language, we may show public service ads or ads in another language. As noted in our programme policies, publishers may not display ads on pages with content primarily in an unsupported language, so please remove the ad code from these pages until we are able to support your language.
  • Your ad code has been modified
    If the AdSense code has been manually modified, such as to change the ad unit width or height or the publisher ID then we may show public service ads. Please select the desired ad format on the AdSense Setup tab of your account and then paste the generated ad code, unedited, onto your pages. Keep in mind that modifications to your code are not permitted by our programme policies.
