Project Wonderful will, very soon, have an inbuilt ratings system for its adverts. This new feature will hopefully give publishers a way to automatically opt-out of adult-rated advertisements. It'll work the other way too, allowing publishers to rate their own websites so that your ads don't end up being shown anywhere inappropriate.
This seems like a good complement to the campaign system, which - for better or worse - allows us to place control of our advertising budget into the hands of a pre-established set of parameters, reducing our need to make decisions on what sites are appropriate for our ads.
Speaking of which, it's been quiet around here lately - how's everyone getting on with the campaign system? Do you still place many manual bids?
