I have a nice blog, with decent traffic on a niche that shouldn't be a problem finding guest bloggers for, and with pr4 I'd assume it'd be easy enough. But it seams almost impossible for me to find guest bloggers, anyone else have some experience with this?
Go on Facebook and search for people in your niche. Ask them if they want to write something. That's been useful for me in finding guest posters.
Remember WIIFM - what's in it for me? That's what every potential guest blogger is going to want to know.
I'd assume pr4 links to their blog would be what's in it for them, or do I need to offer them something else?
What's a PR4 link on your blog when they can get a PR6 link from ezinearticles, for example? Find blogs in your niche. Comment on them a few times. Then contact the owners saying how much you like what they say and ask they'd like to do a guest post. Some people won't do them for free.
Guest blogging is kinda fun anyway most people including me never make guest posts without at least a few bucks. Though your blog home page is pr 4 but the post that someone will be publishing in your blog will not be a pr 4 individually. That's why the page rank is really not the most motivational factor in guest posts.
