Bounce rate is the percentage of visitors who enter a website and then leave rather than continuing to view other pages within the same site. A high bounce rate might indicate that the landing pages aren't relevant to visitors or that the user experience is poor.

Factors affecting bounce rate:

• Page load time
• Content relevance
• Website design and navigation
• Mobile responsiveness

Note: A high bounce rate isn't always negative. For single-page websites or blogs, it might be normal for users to find the information they need and then leave.
