Time to Interactive

Why the audit is important

Page load is a key aspect of how a user perceives the performance of your page. See Measure Performance with the RAIL Method for more information.

This audit identifies the time at which a page appears to be ready enough that a user can interact with it.

How the audit is implemented

This section explains how this audit is implemented, so that you can understand how the audit's score is calculated.

Time to Interactive is defined as the point at which layout has stabilized, key webfonts are visible, and the main thread is available enough to handle user input.

Note that this metric is in early phases and is subject to change.
