Bounce rate is a web analytics metric that measures the percentage of visitors who leave a website after viewing only one page. A high bounce rate may indicate that users did not find the content engaging or relevant to their needs. It is often used to assess the effectiveness of a website's design and content. Understanding bounce rates can help website owners improve user experience. By analyzing the reasons behind high bounce rates, such as slow loading times or unclear navigation, they can make changes to encourage visitors to explore more pages. This can lead to increased engagement and conversions.
