I was reading one of Google's case studies on how one publisher raised his income from 10,000 a month to 30,000 a month with some minor changes.

link to Googles case study: https://www.google.com/adsense/static/e ... ilder.html

Of course I was interested and I checked out the site but it has 6 regular ad units placed on almost all articles.

I'm only able to place 3 + other types of units, how can you place 6 ?

edit: 6 ad units on most pages, not 5. And if 6 isn't allowed for everyone else why is this a case study?

Well, it's not the place to report abuse, or name anyone who would not follow the adsense tos, but I only found 5 google ads per page on the example site.
