Time to Interact: A New Metric for Measuring User Experience
A new performance metric has come on the scene that is less about measuring the actual time it takes for an entire page to load and more about measuring how long it takes for the page to deliver the experience the website visitor is seeking. Time to Interact (TTI) pinpoints the most critical moment in a page load—the moment the page’s primary interactive content is displayed and becomes interactive –from the end user’s perspective. Proponents say this is the new metric to watch because users do not need to wait until the entire page loads to begin to interact with the site. Ideally their experience with a website using TTI as an indicator would be better than using TTL (Time to Load).
