1) Advertise real products or services. Seems like 3/4 of the ads I see on facebook are scams or vapor. Carefully vet your advertisers to make sure they're legit. 2) Make ads relevant. I'm a happily married stay-at-home dad. I'm not interested in dating ads, but ads for better bottles could get my attention. Keyword-driven or site-demographic-driven ads are a start. As dpcan suggested, browsers could allow us to tag ourselves and our interests, which would be even better. 3) Get rid of common annoyances: flashing ads, ads that eat CPU and grind my browser to a crawl, ads on sites I might visit from work or with my kids that aren't safe for work/kids, popups/popunders, ads that block my view of the content I'm looking for, and misleading ads. (Again, if you're a host, vet your ads!) 4) Do not compromise user privacy. Don't track my browsing; base ads off of the site I'm on or information I voluntarily tagged myself with. Many of the webcomics I read use Project Wonderful, and they seem to have a pretty good model. I regularly see interesting ads, and almost never see offensive ads, scams, or CPU killers.
