Yes, it’s important, but actually coming at it from another direction.
If you have an ugly blog layout, people won’t want to stick around. As a result, your Time On Site will be rather low, and this can have a negative effect on your site’s Google rank.
Plus, if you have a good looking, sleek layout, people automatically assume 1) you’re legitimate, and 2) you know what you’re doing. It’s a good idea to spend a little money to have a good looking blog — even a $20 theme from Woo Themes is worth it.
