Google AdSense revenue will drop off if the pay-per-click ads aren’t showing on a blog or website due to stop words, too many ad units or other problems.
Google’s AdSense program enables bloggers and website owners to earn revenue as they display pay per-click-ads on pages of a blog, or website. When a website or blog visitor clicks on one of Google’s contextual ads, the blogger or webmaster earns money in their Google AdSense account.
Google ad revenue for a blog or website can reach into the hundreds, thousands, tens of thousands or more, but only if the ads are displayed! There are several problems that can result in a situation where the pay-per-click Google ads aren’t showing on the page, leaving bloggers and web gurus looking for Google ads troubleshooting tips.
Stop Words or Poison Words Prevent Ads from Displaying on Blog or Website
The Google ads may disappear from the page if stop words, also known as poison words, are present on the page. Google poison words are terms related to subjects like sex, crime and drugs.
It can be difficult to identify the stop words that are preventing Google ads from displaying properly. The precise algorithm relating to poison words is unknown, but some of the following factors may cause pay-per-click ads may turn off:
- Google ads may not show if multiple instances of one or more suspected stop words are present on the page.
- Certain word combinations constitute a poison word; if used independently, those terms will not prevent the Google ads from displaying, but used in combination, the ads will shut off.
- Poison words are believed to have varying ranks. Ads may be interrupted if term x appears only once, where it may take multiple instances of term y to cause an interruption in the display of Google ads.
A Lack of Relevant Google Ads Causes a Google Ad Blackout
Advertisers with the Google AdWords program select keyword terms that will trigger their ad to appear on an AdSense client’s site. So for each page of a blog or website, there is a pool of potential pay-per-click ads. For some blogs or websites, there may be a lack of relevant ads with keywords that match the keywords on the page. This may cause the AdSense ad units to display a solid color instead of ads.
Another reason for a lack of Google ads on a page may result from advertising budget caps set by advertisers in the Google AdWords program. AdWords advertisers set a budget for their online ad campaign; this determines what the daily spending rate will be for a particular ad campaign.
As the day progresses and website and blog visitors click on ads, advertising budgets are expended, causing an advertiser’s ads to “shut off” until the following day. As more and more ads “shut off” for the day, the ad pool shrinks. For niches and topics with a limited number of advertisements, this can mean that Google ads will not display for a period of time.
Bloggers and website creators must also remember that the Google AdWords ads are geo-targeted (i.e. ads for Miami businesses are displayed in the Miami area, while Memphis-related ads are displayed to website visitors in Tennessee, and so on), meaning each website/blog visitor will see different ads displayed. So while the blogger may see that her blog is without Google ads when viewed from her location in Boston, a viewer in London may find that all of the ads are displayed if relevant Google ads are available for London.
Public Service Ads are Showing Instead of Paying Google Ads
Public service ads may be displayed if the AdSense account holder hasn’t provided all of the necessary information to Google, resulting in a hold on the AdSense account.
When new Google ad units are created, it’s possible the account holder selected the option to display public service ads in the event that relevant ads are not available. This can be remedied by editing the settings for the affected Google ad unit. The other options include “Show non-Google ads from another URL” and “Fill space with a solid color.”
Other Reasons Why Google Ads Won’t Show on a Blog or Website
There are a few additional causes for an absence of Google ads. If the Google ad codes were just recently placed on the page, the ad blackout may be the result of the routine delay that occurs. It takes approximately 10-15 minutes for Google ad units to appear once the HTML code is placed on the page.
Some Google AdSense units may not display ads if there are too many ad units present on the page. Google AdSense policy limits the number of ad units for content that can appear on a page to three units of link ads and three traditional ad units that display contextual text ads or ads containing graphics and images.
Google AdSense revenue will depend on how well a page is optimized for SEO and other factors, like location of ad units and fortunately, most of these Google ad problems can be eliminated or avoided by employing good SEO techniques — like strong keywording — on a blog or website.
