Getting people to subscribe to your email list should be your #1 priority. These are the people most engaged with your blog that will provide repeat value for their lifetime.
Each and every subscriber is a real person that wants to hear what you have to say - treat them like that.
You should make it easy for people to subscribe to your email list and make it the main focus of your blog. I have 4 opt in forms on this post and 8 on my about me page.
Don't be scared to ask people to subscribe!
