Interaction to Next Paint (INP) measures the delay between a tap or click and the page visibly responding. Google counts 200 milliseconds or less as good. Anything over 500 is poor.
ট্যাপ করার পর পেজ কত দ্রুত সাড়া দেয় - সেটাই INP।
Why sites fail INP
- Too many third-party scripts: chat widgets, trackers, pop-ups.
- Heavy page builders and sliders running large JavaScript on every page.
- Long tasks that block the main thread during clicks, such as add-to-cart or menu toggles.
- Mid-range Android phones, common in Bangladesh, that process JavaScript slower.
Fixes that work
- 1Remove or delay scripts you do not need on every page.
- 2Load chat and pop-up widgets only after user interaction.
- 3Break long JavaScript tasks into smaller pieces.
- 4Replace heavy sliders and animation plugins with lighter options.
- 5Test on a real mid-range phone, then confirm in Search Console after 28 days of data.
What INP measures
Interaction to Next Paint measures how quickly a page visually responds after a tap, click or key press. Google considers 200 milliseconds or less good, and above 500 milliseconds poor. It replaced First Input Delay as a Core Web Vital in 2024 because it looks at interactions across the whole visit, not only the first one.
How to find the slow interactions
- 1Open the Core Web Vitals report in Search Console to see which URL groups fail INP on mobile.
- 2Test a sample URL in PageSpeed Insights and check the field data section.
- 3In Chrome DevTools, record a Performance trace while tapping menus, filters and add-to-cart buttons.
- 4Look for long tasks over 50 milliseconds and note which script causes them.
Why INP is harder on Bangladeshi traffic
Much local traffic comes from budget Android phones with slower processors. A script that feels instant on a laptop can block the main thread for half a second on these devices. Testing with CPU throttling in DevTools gives a more realistic picture of what your visitors feel.
Frequently asked questions
What is a good INP score?+
200 milliseconds or less at the 75th percentile of page visits is rated good by Google.
Do WordPress plugins affect INP?+
Yes. Page builders, sliders, chat widgets and tracking scripts often add heavy JavaScript that delays interactions.
How long before Search Console shows an improvement?+
Field data covers the last 28 days, so improvements usually appear gradually over about a month.
