Challenge we solve
How we solve High INP (Interaction to Next Paint)
In our experience, high INP (Interaction to Next Paint) means there's excessive delay between a user's interaction, like a click or tap, and the browser visually updating in response, measured across the page's full lifecycle rather than just first input. The typical cause is long running JavaScript tasks blocking the main thread, so the browser can't process the paint update until the script finishes. INP replaced First Input Delay as a Core Web Vital in 2024, and poor scores here directly affect both perceived responsiveness and search ranking signals.

Why this happens (and how we fix it)
In our experience, INP measures the worst interaction delay across the entire page lifecycle, not just the first click, so it's typically caused by long running JavaScript tasks that block the main thread at whatever moment a user happens to click, tap, or type. Heavy third party scripts, chat widgets, ad tech, analytics tags, are frequent offenders because they execute on their own schedule with no awareness of when a visitor might be trying to interact with the page. Poorly tuned event handlers that do expensive work synchronously, like re rendering a large list on every keystroke, are another common source that only surfaces under verifiable interaction rather than in a simple page load test.
What it costs you while it goes unfixed
In our experience, A page can look fully loaded and still feel broken if every tap or click has a noticeable lag before anything visibly responds, and that mismatch between appearance and responsiveness is one of the more frustrating experiences a site can produce. Since INP replaced First Input Delay as a Core Web Vital in 2024, it carries direct ranking weight, so sluggish interactivity isn't just an UX complaint, it's a verifiable search visibility cost. Interaction heavy pages, forms, filters, configurators, are hit hardest, meaning the pages most responsible for conversions are often penalized most.
