Well it looks good from a stats point of view. I know you said it's a niche site, which doesn't tell us too much. I understand if you don't want to reveal your niche, but perhaps you'll consider at least sharing the category your niche is in. Also, have you done any promotion on this site, or are you just getting these results merely from posting the 3 posts? More details would give us more insight and enable us to give you better and more realistic feedback on how you're really doing. There's a lot of different variables involved. Anyhow, wish you the best and do keep us updated on your progress and any changes.
