The theme you choose for your blog is the first impression you give readers when they come to your site. That’s why it’s so important to have a theme that’s responsive, aesthetically pleasing, and easy to navigate. I can’t tell you the number of times I’ve left a blog simply because I didn’t like the way it looked or it was hard to find what I was looking for. That may seem harsh to some, but it’s the truth. If a blog looks unprofessional I’m not going to trust what the author has to say.
