For some time now I have followed the pack in choosing the layout of my sites. A three column design with site navigation on the left, content in the middle, and links on the right. The right hand column was reserved for my pay-per-click advertising.

I use Google Adsense pay-per-click ads as my right hand column. I was hoping this would give the visitor who did not find what they were looking for on my pages an alternative. Google does a good job of supplying ads that are relevant to your site.
