A high bounce rate comes from not reaching your targeted audience, poorly designed site, or lack of quality content. Your site design is good Content is ok, but could be a better. Think about embedding some videos from the Center for Disease Control (CDC). Or puttting some podcast on your site. The CDC has some free podcast you can download and put on your site. There is even a podcast plugin for wordpress. Targeted audience - if you are depending on google to give your site low bounce rate traffic, think again. Google is good at giving results, but its not perfect. Google search traffic on my main forum has a bounce rate of 48%. While traffic from my youtube account has a bounce rate of 18%. I suggest you sign up on some survivalist types forums and put a link to your site in your signature. Getting traffic from survival, disaster preparedness forums and blogs will be a lot more targeted then depending on google.
