to replace the PSA that appears, in the script you can add google adsense alternative urls, can use a script from google that you have uploaded to your host or use the url that you've prepared to replace if the PSA that appears.
this method I pake in all my web, including on this blog.
eg like this:
<script type="text/javascript"> <! -
google_ad_client = "";
google_alternate_ad_url = "http://www.yoururl.com/altads.htm";
google_ad_width = 160;
google_ad_height = 600;
google_ad_format = "160 × 600_as";
google_ad_type = "text_image";
google_ad_channel = "";
google_color_border = "f2e6bc";
google_color_link = "6d310d";
google_color_bg = "f2e6bc";
google_color_text = "000000";
google_color_url = "000000";
//-></ Script>
<script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"> </ script>
in the code that I make bold is the alternative url. if the PSA appeared then to be replaced / filled with pages that exist in http://www.yoururl.com/altads.htm
Another way is to use the collapsing ad unit script, which is usually my pake for which I put the adsense code within / between posts, to avoid the blank if the ad does not appear / PSA.
enough "save link as .." for Firefox or "save target as ..." for Internet users google_adsense_script.html file explorer.
upload the file to the root of your domain, then use as alternative ads in your adsense code, like this:
google_alternate_ad_url = "http://www.yourdomain.com/google_adsense_script.html"
