Plan and simple, yes you want to guest blog, but you want to be picky about the sites you are guest blogging on. I say this because you want to make sure your blogging on a site that is actually going to help you get target traffic to your site. You don’t want to waste time and energy creating a blog post on say SEO (which is your specialty) on a blog that is dedicated to preserving Barbie. The point of guest blogging is that it is a win win for the webmaster and the guest blogger.
