I’ll be testing how well Google Adsense does for me with different setups and locations on my F-Body Forum for the next few months. I’ll go a whole month with each set-up and determine which seems to give the best clicks.
One thing you should know is that I added conditionals that make it so only guests can see the ads. Some people don’t like doing this because it limits the amount of people seeing it, but I personally think that your members are less likely to click an advertisement than a guest. Also, why harass registered members with ads when you can keep it nice and clean for them without them?
My Setup for this month:
LinkUnits Matching my forums colors and scheme in sidebar and under the navbar.
