Here are a few guest post guideline pages that I feel give guest bloggers ample information, and set clear expectations:

http://www.veronicasicoe.com/blog/guest-post-policy/ – The following paragraph hits home the importance of authenticity: “To have your post published on my blog, I would very much like it to be well written and intelligent, be useful and offer a fresh perspective or new information on a relevant topic, and also be creative and 100% you.”

http://geekalabama.com/media-pr/geek-alabama-guest-post-policy/ – This page sets expectations for links and social citations quite well. I like how this page talks about what is in it for the guest blogger by sharing information about the Geek Alabama social following.

http://www.eazypeazymealz.com/disclosure/guest-post-policy/ – Touches on key considerations such as originality, a link in the byline, and quality. I also like how Racheal (the blogmaster) gets potential guest bloggers excited by starting off with “we love guest posts!

http://www.chieffamilyofficer.com/about-2/cfo-guest-post-policy/ – Lays the land with transparency about how many inquiries she receives. I like how there is a distinction between sponsored posts and guest posts, and the blogmaster points prospects with a promotional agenda in that direction right there on the guest blogging guidelines page. The recommended readings featured at the bottom is also super smart!

Hope this helps
