Initial Viewport

This curve shows what share of users reached each depth of the page; the horizontal dashed line marks users' dominant screen-edge boundary.

This metric is your main watchdog for conversion-rate optimization and the placement of critical elements. Imagine you want to know whether the page's main buy button is visible without scrolling; if the dashed line sits above that button's position, most users never see it without scrolling. Using this data, you always place key content and calls to action inside the initial viewport so you never lose an audience before they even start interacting.
