Monday is starting a new wedding website and wants to have advertising, but has no clue what to charge. Leo says not to do it herself. She should start with Google AdSense. They'll take 45% of the ad revenue, but they do all the work, too. Once the site gets serious traffic, then she can go out and start selling ads herself. She shouldn't quit her day job yet though, it won't be a lot of money. Cost per click is far more lucrative than impressions. It's easiest to sell a monthly flat rate, especially with a new site.
