Just a quick link building tip and a shout out. Offering a prize in a blog contest can gain you one or more links from the blog holding the contest, and will likely also gain you a link from the winner of the prize you've offered. Here's an example (and the shout out). I entered one of the many sub-contests of the large Problogger contest held this month, and I was a winner. So here's a big shout out and thank you to Better Wallpaper who supplied the prize that I won. I'm getting a giant bit of wallpaper (the real kind, for a wall) for my granddaughter's room. She's going to love it.
See how that works? Get a link from the contest blog and get a link from the winner. And that shout out link is dofollowed, because it's a true vote from me!
