Bounce rate is a metric used in web analytics to measure the percentage of visitors who leave a website without interacting beyond the initial page, which can impact a site's SEO ranking. While a high bounce rate is often perceived negatively, indicating potential issues like slow load times or intrusive ads, it can also reflect visitors quickly finding what they need. Factors influencing bounce rates include the relevancy and accessibility of content, as well as technical aspects such as page design and load speed. Understanding bounce behavior is nuanced, as variations depend on business type and user intent, with some bounces being benign, such as when users find desired information and leave promptly.
