When asking for links, what are good incentives to offer?

[ResslerMotors]

The best incentive you could possibly offer is great content.  Something that truly benefits their readers/visitors.  But the non-utopian answer would be what Shannon said - free random offline item that isn't really e-traceable and is inexpensive.

On a side note, I may give you a link for the gallon of milk thing... just saying...

Back to the milk thing:

If you make it funny it could be a really good link bait scheme!

Create a separate website all about doing the challenge, generating tons of links*, and then just 301 it into your main website when the fad is over!

*Not exactly sure what kind of links you would get from puking on camera...

Cheap wine?

Exactly! Things like cheap wine, cigars etc are all good ways.

I second that idea. Guaranteed re-tweet on that video.

I prefer writing a short blog for a link. They can either post it in their blog or your own. We all know sometimes coming with ideas for blogs for your own site is very tedious.

You could write a positive article about them or provide them with a testimonial that they can add to their site.
