# INP in 2025: 77% of mobile sites pass, but the top 1,000 lag at 63%

## The short answer

About 77% of mobile websites had good Interaction to Next Paint in the 2025 Web Almanac, up from 74% in 2024. Popular sites trail: the top 1,000 reached 63%, up from 53%. Desktop stood at 97%. On mobile, home pages hit 80% good INP while secondary pages fell to 69%, an 11 point gap.

## Key takeaways

- Mobile INP improved to 77% of websites with good scores in 2025, up from 74% in 2024, while desktop held at 97%.
- The top 1,000 websites gained the most, rising from 53% to 63% good INP, yet they still sit 14 points below the overall mobile average.
- Mobile home pages reached 80% good INP, a 7 point gain, while secondary pages slipped to 69%, opening an 11 point gap that did not exist in 2024.
- Lab Total Blocking Time worsened by 58% even as field INP improved, so lab scores alone no longer predict what real users experience.

Interaction to Next Paint is the Core Web Vital that measures how quickly a page responds to
clicks and taps. The 2025 Web Almanac Performance chapter, built on Chrome UX Report field data,
shows mobile INP improving overall while the busiest sites and inner pages still struggle.

## How many sites have good INP?

For an origin to be rated good, at least 75% of sessions must record an INP of 200 milliseconds
or less. On that bar, 77% of websites passed on mobile in 2025, up from 74% in 2024. On desktop,
97% had good INP, 2% needed improvement and less than 1% were poor. On phones, 21% needed
improvement and 3% were poor. The mobile-desktop gap narrowed to 20 percentage points.

## Do popular websites pass INP more often?

No. Segmenting mobile origins by rank, the Almanac found good INP at 63% for the top 1,000
websites, 56% for the top 10,000, 56% for the top 100,000 and 64% for the top 1,000,000. The
figure climbs to 76% across the top 10,000,000 and 77% for all websites.

The top 1,000 improved fastest, from 53% to 63%. They were 21 points below the average in 2024
and 14 points below in 2025. The Almanac attributes the difficulty to heavier JavaScript,
richer interactive features and third-party integrations on high-traffic sites. It calls the
gains likely the result of manual optimization of complex JavaScript.

## Do home pages or inner pages respond faster?

Page-level CrUX data shows a split that was absent in 2024, when mobile home and secondary pages
scored 73% and 72%. In 2025, mobile home pages reached 80% good INP, a 7 point gain, while
secondary pages fell to 69%. On desktop the two were close, at 97% and 95%. The Almanac points to
filters, carousels, form validation and late-loading third-party widgets as likely causes on
deeper pages, so audit templates beyond the home page (see [technical SEO](/topics/technical-seo)).

## Does lab Total Blocking Time still predict INP?

Less than before. Total Blocking Time is a lab proxy for responsiveness, yet the Almanac reports
it rose 58% while field INP improved. Median mobile TBT was 1,916 milliseconds against 92
milliseconds on desktop. The Almanac suggests sites may be tuning the interactions that dominate
INP while background JavaScript work still blocks the main thread. Judge INP from field data.
