Effectiveness of BlogUpp!

I have just checked the statistics, and here are what I got:

Total outbound impression is: 20.7k
Total outbound visit is: 55

Total inbound impression is: 14.5k
Total inbound visit is: 17

The click rate is very low as I can see, and this could be explained by the fact that my astronomy blog is too specific and thus general blog readers might not find interest.

But as BlogUpp! always emphasis, content is the king.
