Understanding Bounce Rates

by Greg Pike, Applecore Web Developer

Bounce rate. It's one of the top Google Analytics metrics and yet many people are still confused by it. What does it mean next to exit rates? What's the difference?

 A “bounce” is when a user has shown little interest in your website. In other words, when a user hits your website only to leave or ignore it immediately.

 The bounce rate is therefore the percentage of users who bounce. If four out of every ten users bounce, your bounce rate is 40%. This says four out of every ten users came to your site, didn't find what they were looking for, and left.

 Bounce rate: "I came. I puked. I left." - Avinash Kaushik, Google’s Analytics Evangelist and author of Web Analytics: An Hour A Day.

Average Bounce Rate

Bounce rate is a performance measure for a website, particularly websites keen on converting users into customers like e-commerce websites. Most bounce rates will be somewhere between 35% and 60%. It's good practice to strive to reach the lowest possible bounce rate you can for a website.

Causes of High Bounce Rates

High bounce rates can be caused by a number of factors.

  • Poor content. Users are nosy and want to learn more, but if your content isn't useful or not relevant they will not waste their time.
  • Misplaced links, buttons, graphics or ads. Web users are very impatient and if they don't see what they want right away, they'll simply leave. Review how you're communicating to your users or redesign your website to draw them in. Google’s Website Optimizator will allow you to compare visitor metrics for multiple versions of the same page. Try creating several versions of a page to determine what will perform better.
  • Abbreviated domain name. Many organizations share abbreviated names. For example, MWI is both the name of a search engine marketing company (mwi.com) and conflict mediation company (mwi.org).
  • Start pages. Any user that has your website set as their start page will hit your website every time they open their web browser.
  • Information pages. Users can be quick to jump around to find the information they desire. Information pages tend to have high bounce rates because users hit them to learn something specific, and when they acquire that knowledge they return to where they came from or move on.

There are some websites that will have high bounce rates and there's very little that can be done to change it. For the other websites that want to take action and lower their bounce rate, there isn't really one solitary solution. Every website has different content, different audiences and many other distinctive factors that make it unique-- which means improving bounce rate can only be taken on a case by case basis. That magic word or one-step process to give you a better bounce rate? It doesn't exist. 

Bounce Rate and Exit Rate

At first glance, it might be difficult to see a difference between bounce and exit rate. Exit rate is similar to bounce rate, but differs in that it calculates the percentage of users that "exit" the site from any particular page. For example, a user hits the default landing page and navigates to a news article. There is no bounce because the user stayed on the website. Then the user goes to google.com and searches for something. This is an exit. Exit rate is the percentage of users that leave the site from a given page divided by the total number of users that visit that same page.

 Let's break it down.

Ten users visit the Applecore Games page.

Two users hit this page from a search query and the other eight all get there from the site navigation (meaning they were already on the Applecore site before going to the games).

One of those two users (from the search engine) leaves the page and goes back to their search results and the other one clicks a link and plays one of the games.

Of the other eight, three users leave the website and go to eBay to buy books on the definition of Exit Rates.

The other five click on links and also play the games.

Bounce Rate: 1 / 10 - 10%
Exit Rate: 3 / 10 - 30%

 

Exit rate is not necessarily a bad thing. Users cannot stay on your website forever. It does, however, give you insight as to what pages leave your visitors feeling the need to move on.
