The Metric of Disappointment
A "bounce" occurs when a user lands on your website and leaves without triggering any other requests to the Google Analytics server (i.e., they didn't click any internal links). A high bounce rate typically signals a massive disconnect between what the user expected when they clicked your link, and what your landing page actually delivered.
Diagnosing High Bounce Rates
Clickbait Disconnect
If your Facebook ad promises "70% Off TVs" but the link drops them aggressively onto a generic homepage filled with blenders, they will instantly bounce in frustration.
Mobile Unresponsiveness
If a user arrives on their smartphone and the text is microscopic, the viewport is broken, or the buttons cannot be tapped, the bounce is physically guaranteed within seconds.
The "Good" Bounce Paradox
A high bounce rate is NOT universally bad. If a user googles "Customer Support Phone Number," lands on your Contact page, grabs the number, and leaves... that was a flawless user experience, but it registers mathematically as a 100% bounce.
