How Do I Measure Ad Density?

The average blogger will increase their ad frequency in Q4, all the way to the end of the year. If I can visually look at a page and realize that it's not a compelling experience for the user, maybe I need to change things. We use common sense with regards to ad density settings. But my advice is always to err on the side of caution. The only people we're making rich are the ad companies by doing that.
