Adsense Differs on WWW vs Non WWW

One works one doesn't

[graywolf]

I have a new site that went up 2 weeks ago with adsense on it. The theme of the page is very clear so adsense doesn't have a problem getting the ads targeted properly. The one thing that does happen is the WWW version continues to show PSA ads while the non-www version shows ads properly. I redircted the non-WWW version to the WWW version using htaccess but the PSA's still continue to show three days later. Any suggestion on how to "fix" the problem?

You could always do an htaccess redirect so that you could access either www or Non-WWW

Current thinking is that having both versions out accessable allows the pages to be seen as duplicates of themselves, and get penalized.

graywolf –

This is another case that’s difficult to troubleshoot without being able to see your site. However, I have a couple of possible solutions.

First, does the ‘www’ version of your site frame the content of your non-‘www’ version? If so, you will need to generate special AdSense ad code to receive properly targeted ads on your sites.

To do so, you can select the 'Framed pages' checkbox on the 'Ad layout code' page of your AdSense account when generating your ad code, and make sure to place the ad code in the same frame as the content of your web pages in order to serve relevant ads. For more information, see:

Another explanation is that your pages may have been crawled at different times. When you first add the AdSense code to your sites, it’s normal for public service ads to show for 48 hours or longer. While one of your URLs may have been crawled almost immediately, the other may have taken a bit more time.

If you want me to take a closer look at your sites, please feel free to sticky mail me.

Frames, ACK no!

To be honest the htaccess wasn't configured properly when I put up the URL a few months ago. I only fixed it when the site content went up 2 weeks ago. So I guess it's possible that it crawled both versions at different times. It's not getting any traffic to speak of now so I'll give it a few days to work itself out. If things stay "broken" I'll let you know. Thanks.
