Interaction to Next Paint over 500 ms

Warning severity, in the performance tab

Why it matters

Real visitors wait more than half a second for the page to respond to taps and clicks. Google's threshold for a good INP is 200 ms; INP is a Core Web Vitals ranking signal.

How to fix it

Break up long JavaScript tasks, defer non-essential scripts, and keep event handlers light; measure with the Performance panel in Chrome DevTools.

How Crawlune finds it

Crawlune flags Interaction to Next Paint over 500 ms automatically on every crawl and lists the affected URLs under the performance tab, where you can filter, inspect each page and export the list to CSV. The free version crawls up to 550 URLs with every check enabled.
