There really should be any problems. Checking out the main index page, there are 3 blocks. Two are above the first post, and one is in the sidebar. Perfect.
I also have them configured to appear in single posts exactly the same way. However, viewing my single post pages, only one ad block is appearing. It’s almost like Google Adsense thinks that 1 block is worth 3, so the other 2 blocks (one in the top and one on the sidebar don’t appear).
Could this be a problem with the layout, or is Google to blame here? I am using the Smashing Magazine theme.
