You can use it to place ads across multiple blogspot blogs but not across any other websites. If you try placing blogger adsense code on any other websites it shows as blank spaces. To put it on any other sites you need to get second stage approval by submitting a site just like a normal adsense application. They closed the blogger loophole off a couple of years back
