well. I'm no expert, but I can sure take a shot of some things you might want to avoid!

   *Not marking ads as ads
   *Presenting advertisements with the same presentation inline with normal 
    content, potentially confusing the reader.
   *Assuming that no one would block the ads
      -or recognizing they would and not caring
   *Not making use of the space in the... article!

I did not notice I could scroll down, either. Why didn't they put the ads there?!
