Adsense sees http://domain.com and http://www.domain.com differently - help

I set up adsense up my website just over a week ago, and am finding
that the index page for http://www.thethoughts.co.uk/thoughts doesn't
have content sensitive adds.

Meanwhile using the url, http://thethoughts.co.uk/thoughts *does*
display content sensitive adds. Is there anyway I can get the content
sensitive ads to appear on the www url?

Thanks

 

Also I placed a referal ad for Firefox at the bottom of the right sidebar on the site. Yesterday the ad displayed fine, today it isn't even there. However the code is still in place. What could be causing this?

 

You could try using a 301 redirect to permanently transfer http://domain.com to http://www.domain.com or vice versa. I'm not totally sure but I imagine that will solve the problem.

Here's how to do it:

Basically those are two different addressess (www vs. non-www), so AdSense bot needs to index them both (for each page!) as different locations. Either do a redirect in your htaccess like this:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.mydomain\.com
RewriteRule (.*) http://www.domain.com/$1 [R=301,L]

Code (markup):

or just wait for the AdSense bot to properly index and identify both versions of the same pages (the redirect method above is preferred though).

 

That's great! Thanks for the quick replies...

 

No probs - hope it solves the problem

 

Thanks. I have set this up and it now works.

One question though - could this sort of redirect present any problems with Google? For example could it be considered tricking the GoogleBots via the redirection?

Cheers...

 

No , google actually prefers that

Cheers

Happy Easter

 

Just as he says it helps. It also helps your SERP rankings. If you read the quote I posted it states that people think that doing this 301 redirect helps prevent duplicate content penalties.
