How Do You Get Your Site On Digg's Front Page?
If you're KTVZ, you just get oddball content off the AP wire that will occassionally get you a pile of traffic. But if you don't have an AP wire feed like they do, there are a couple of not-so-ethical methods to go about it.
Either you can follow these 10 steps on the SEO Black Hat site, or just buy yourself some Diggs on User/Submitter. They'll get you on there, but I don't know if I'd be able to sleep at night.
On a related note, I've gotten hit by Digg once (that I know of), and I didn't use either of those methods.
