Dear experts, I'm vexing over why google ad sense is rejecting my website, twice already.

They give me this message :-

We did not approve your application for the reasons listed below.

Issues:
- Difficult site navigation

I hope some one can explain to give what they meant by difficult site navigation. What must I do in order to make my site become easy navigable....As far as I know, it is just a very very simple web site whereby I'm still cracking my head how to increase the traffic to the website and customers...
