Guest posts should generate you a ton of extra traffic. If not, you're doing something wrong. When I publish a guest post here on Basic Blog Tips, or on Famous Bloggers, or Pro Blogger, I see a jump in my opt-ins. Sometimes the spike is stunning, as I receive 5 times the opt-ins I would see on a normal day. This is how it should be, too. I mean, of course I am here to add massive value, and draw readers to this blog, but I would also like to draw readers to my blog so that I can build my list.
