Why do certain pages have high bounce and exit rates?

[davids]

Some pages will have high BR. But that doesn't mean it's bad. As long as the page serves it's purpose, it's totally agreeable.

Take the sales page for example. The visitors clicks in the landing page to get to it then the sales page just sends the visitor to the check out page through it's link. Sure the sales page itself will have 100% bounce rate but that doesn't mean that it is unable to do it's job!!!
