Bounce rate it said that users doesn't feel like your site is attractive for them. At least not at the first impression.


There are couple of possible reasons for this.:
1. Bad design/placement of site zones may simply make users close quickly browser windows related to your site

2. Your site is attracting other users than your site target. This could be due to wrong SE optimization or wrong link building (or banner exchange, aso).

What stats system do you using ? I can tell you where to look to for checking what kind of users are bouncing more and can give then a much better evaluation.

If you willing to post your URL i can make also a short evaluation.

Is a very unpleasant thing to see you got visitors but they leave quickly...
