Bounce rate is one of the most important metrics used by webmasters and marketers to measure the engagement level of visitors on their website. However, it's not the only term used to describe this metric. Other synonyms include exit rate, abandonment rate, and drop-off rate. All of these terms are used to describe the percentage of visitors who leave a website after viewing only one page. The higher the bounce rate or exit rate, the less engaging the content of the website is. Abandonment rate and drop-off rate are similar terms used to describe the same metric. These synonyms are important for webmasters and marketers to understand and use appropriately when analyzing website traffic.
