Hi there! Adsense PSAs come and go, then come back again, on my homepage. And only on my homepage. All the other pages have regular adsense ads. Why could this be? Anyone has any explanation why this happens and how to resolve this? I've reported my problem at google adsense's help forum but the answer given me has been vague to me. Please, I need help to get the PSAs out of my site.
There are several reasons for displaying PSA: 1) Google's 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.Note: Google's crawler indexes by URL and therefore considers http://site.com and http://www.site.com different URLs. Because Google's crawler will visit these URLs separately, you may notice ads appear differently on these pages. 2) Google's crawler can't reach your site. If our crawler isn't able to access your page, we'll provide you with an error message on the Site Diagnostics page of your account. 3) Your page may contain sensitive content. Google's 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. 4) 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 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. 5) 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.

Use these commands, may be they will help. These commands will tell Google (adsense) crawler that which content to crawl for displaying ads <!-- google_ad_section_start --> <!-- google_ad_section_end -->
