Not showing the right stuff

Hi guys, I couldn't figure out where exactly to post this.

I have a website, let's say www.mywebsite.com
When I type in http://www.mywebsite.com it won't show the right ads, it will only show Googles "What's the highest number on earth, Google.com has the answer" kind of ad.
Now, if instead of typing http://www.mywebsite.com I manually type http://www.mywebsite.com/index.php (which should be the one it loads) it will show correct ads.

I tried to rename my index.php to main.php and make a Meta Refresh to forward me to main.php, but then it wouldn't show the adds again.

Only when I point my browser to index.php it will work.

It's all in Swedish, so I don't think it would help giving out the address.

Any ideas?

 

Not really sure about this one... Does the homepage have a lot of content on it so that the spider can actually determine the topic?

You could try section targeting but I'm not sure if that'd help as your case is strange... Worth a try though

 

You mean your content is all in swedish??

 

Ok, I'll show you.
http://www.utmaningsverkstan.se
Look at the add on the top of the site, google crap.
If you click the link to the right that says utmaningverkstan.se (which works as a home, and will display the same as the one you landed on to start), it will show ads about scrapbooking.

Isn't that weird?

 

That is very weird indeed...
