AdSense Stop Words & PSAs
What`are “AdSense Stop Words”?
These are certain words that trigger ads to show PSAs or Public Service Ads. PSAs are fairly common for new content but you should be getting normal ads after a few page refresh (threshhold is 4 hours). See example of a PSA here. Since these ads are “pro bono”, you as a publisher don’t get a single cent when they appear on your site.
However, aside from websites with unsupported languages, stop words can also trigger them. These are words that are not in good taste.
Profane or cuss words can trigger them as well as sex-related words. Other categories might include the following:
If your blog has any one of these as a “theme”, or maybe even words as being part of your domain name, you’ll most likely to get PSAs all the time.
Other factors include frequency of appearance of these words in your content (not sure if the 3% keyword density applies), combination and proximity with other words, among others. One reason why you should also monitor your reader comments for such words.
If this is the case and you can’t stop from using these stop words, either be creative in morphing them (use of special characters), using images instead of texts or drop Adsense altogether.
