Hi,
One of my site has around 80% bounce rate. I am not aware much more about bounce rate but it seems it's a one time traffic. I mean the visitors visit only one page and then leave my site. Correct me if I am wrong. Also how can I reduce bounce rate ?
Yes, bounce rate means one time traffic. If the visitors don't get the contents which they want then there is a chance that they leave your web site without visiting other pages. If you have high traffic from Search engines then you should have required contents from which visitors get your web site otherwise they will leave your site.
