Of all the verbage thrown around when working with online marketing, a term that is often used as a negative, would have to be bounce rate. Used usually as “The bounce rate of your site/page/products is why you don’t have conversions” It’s seen as a black spot on a site, and needs to be handled as soon as possible. Bounce rate can also be used as a metric for growth as well how ever, if your SEO expert is on the ball, they’ll understand how to analyse and adjust your pages to change that rate.
A definition via Wikipedia:
Bounce rate (sometimes confused with exit rate) is a term used in web site traffic analysis. It essentially represents the percentage of initial visitors to a site who “bounce” away to a different site, rather than continue on to other pages within the same site.
A visitor can bounce by:
Clicking on a link to a page on a different web site
Closing an open window or tab
Typing a new URL
Clicking the “Back” button to leave the site
Using the above list, you can begin to personally gauge where your pages may be going awry with a high bounce rate. Do you include links to external sites? If you do, are those sites also yours? Do you have loud music/sounds or flashy videos on your site which may startle people and annoy them to closing your page? Is there nothing eye catching on the page to compell visitors to stay on your site? Session timeouts are generally gauged in the 30 minute range, and if a visitor hasn’t purchased your product, or visited other pages on your site within that time frame, then you need to begin, by looking at your content.
Just as a rule of thumb, remember that your SEO can bring you visitors, it’s up to you to convert those visitors to customers and/or clients.
