I've never had this happen with any of my other sites but my new forum seems to be getting PSA on pages that have been up for a few days. http://alphamaletalk.com/ftopic29.html for example is giving PSA. Any tips, on all my other sites it seems to be instant.
Put useful keywords in your titles for a start "alphamaletalk.com - view thread - the best..." not 1 useful keyword.
It is all of the swear words in the 3rd post that are triggering the PSAs Check this out http://www.vaughns-1-pagers.com/internet/google-adsense-words.htm Ross
heh i know that bomb is a bad adsense word (on that list) A user submitted a picture of a stealth bomber that flew over the rose bowl, and I almost always get PSAs on that page
To avoide PSA use alternative url, google does allow you to have an alternative url as a iframe if there is nothing to show, instead of displaying PSA. untill your site gets some good traffic. and till you add few keywords!!
I have the same issues with the index page of Article Depot which nearly always shows the alternate ad. A few times I have seen AdSense Ads but they seem few and far between. The subpages that essentially use the same template have no issues showing ads. My problem is not swear words but seems to be something else.
Initially start off with a small button ad on the homepage if you have PSA problem, one's the ads become more persistent you can start increasing ad space! This is what the answer I got when I contacted google for complaining about lack of persistency in ads.
