AdSense Sandbox 1.0 is a different tool from the Google Adsense Preview tool, that apparently works on IE only. The biggest benefit of this tool is that it allows you to preview ads that will most likely appear on your website, based on your URL or keywords. Other than 20 text ads, this Preview tool will also show the related Adlinks and Rich Text Ads (Images and Video) that will appear on your webpages for visitors in various countries. Ad formats include Leaderboard, Skyscraper, Rectangle and Square (200×200).
Another advantage is to find stop words – those keywords which are sensitive in nature and adsense blocks ads on such pages to reveal public service ads. So if for a keyword, sandbox shows no ads, maybe it is a stopword for google and you should avoid it in your page content.
A great tool for doing experiments on your websites and for choosing the right keywords when posting an article. It may also help for filtering your ads if you want to. This tool really works and will not charge the advertisers even if you click on the ads because Digital Inspiration uses internal codes with random AdSense Publishger ID’s.
