please tell me, this tool use for what?

I have been see, and read this tool : http://www.digitalpoint.com/tools/adsense-sandbox/
But, i still dont understand that this use for what or just see what ads will display on the page we put?

 

This is a handy little utility if you would like to see what sort of Google AdSense ads based on content or keywords. Simply enter the URL or keywords in the box below, and you will see up to 20 sample AdSense ads for the URL or keywords.

 

I tried it.
It may out of order already.
It does not go any where.
It shows same for all searchings.

 

It works only if the "url" has a few keywords in it.

 

I think it's offline temporarily.

Would have been nice to see if adsense fit into some of my higher traffice landing pages. Oh, well.

.

 

Isn't it a lot better to use the Adsense Preview Tool from Google?

 

The adsense preview may be more useful, but in the case of someone wanting to find out before actually signing up for adsense, then this is an alternative.

 

so, that tool only give us some ad that will display if we use adsense on page we check?
And any else?
