What is the Interaction to Next Paint (INP) for Shopify?
Shopify Interaction to Next Paint (INP) is a metric used for speed optimization to measure how quickly a Shopify web page becomes interactive for users. It assesses overall responsiveness and the duration of event handling, making it crucial for Core Web Vitals for Shopify.
What Are User Interactions on Shopify?
User interactions are directly related to how quickly a Shopify website responds to actions like clicks or key presses. For example, “Click, Tap” interactions on a touchscreen device involve multiple events, such as pointer up, pointer down, and click. Additionally, interactions can be driven by JavaScript and CSS from specific elements. Specifically, INP measures the time elapsed between a user interaction (such as a click or key press) and the subsequent visual update on the page.

- Input Delay: The time spent waiting for background tasks that prevent the event handler from executing.
- Processing Time: The time taken to run event handlers in JavaScript.
- Presentation Delay: The time spent managing queued interactions, recalculating the page layout, and painting page content.
