What can I offer a blog, in order for me to guest blog on their site?

What strategy is most commonly used to guest post on blogs?

[DanSpeicher]

Quality content. Ask them what they want on their blog.

Before you even ask them for what they want, see if they already tell you what they want. Search the website for information about guest posting and what they're looking for. You won't make points asking how to guest post when there's a post pointing everything out. Here's what Copyblogger looks for, for example. http://www.copyblogger.com/guest-post-guidelines/.

First, take a look at the blog that you are looking to be a guest writer for. You should look for their style and of course, look at what they are writing about. Once you have done this, go ahead and create content that is relevant to what they write about; if it is a fashion blog, write about the latest trends and add images (again, look at what they have and copy the same style; you can give them something that copies their style and another option that is more your style). Email them and send them your work. If there is a number to call, I would call them first and then email them. Hope this helps!
