Exit rate is the percentage of visitors who leave your site from a particular page.
Exit rate is the percentage of sessions that ended on a particular page, calculated from the number of exits on that page divided by the total number of pageviews it received. Every session has to end somewhere, so every page has an exit rate. What the metric tells you is how often a given page was the last one a visitor saw before leaving the site, regardless of how they got there or how many pages they viewed beforehand. If a page was viewed five hundred times and two hundred of those views were the final action of the session, its exit rate is forty percent.
The mechanics rest on a distinction that trips up many people: exit rate is not the same as bounce rate. A bounce is a special case in which the page was both the first and the only page of the session. An exit simply means the page was the last one, whether the visitor saw one page or twenty before reaching it. Because of this, a page can have a modest bounce rate but a high exit rate, which usually means people arrive elsewhere, browse through, and then consistently leave from this particular page. Analytics platforms compute the figure per page so you can rank which pages most often serve as the door out.
The word "exit" comes from the Latin "exitus," meaning a going out or departure, and the metric itself is a native creation of web analytics platforms that needed a way to describe precisely where visitors leave a site. Unlike some marketing terms with long offline histories, exit rate was born from the practical need to map the last step of an online journey once every page request could be logged and sequenced.
Exit rate matters because the last page a visitor sees reveals where your site loses momentum. On a checkout flow or a lead form, a high exit rate on the payment or submission step is a direct signal of friction that is costing you conversions and revenue. On informational pages the picture is more nuanced, but a surprising exit spike on a page meant to lead somewhere else, such as a category page that should funnel into products, points to a broken or unconvincing next step. For a business owner, exit rate turns a vague sense that "people are leaving" into a specific, addressable location.
The most common mistake is alarm over high exit rates on pages where leaving is natural. A confirmation page after a purchase, a contact page, or a thank-you page should have high exit rates, because the visitor has finished what they came to do. Judging those pages as problems wastes effort. The productive move is to focus on pages that sit in the middle of an intended path, where an exit represents an interruption rather than a completion. Reading exit rate alongside the conversion funnel, the flow of pages, and the intent of each page keeps you from chasing false alarms and lets you concentrate on the genuine leaks where visitors slip away before they were meant to.
Exit rate pinpoints where visitors abandon their journey. Spotting unexpected exits helps you fix the pages leaking potential customers.
