![INP Benchmarks 2025 Graph]
Google’s Core Web Vitals have shifted — and 2025 marks the full replacement of FID (First Input Delay) with INP (Interaction to Next Paint).
This update redefines how developers and SEO professionals should measure responsiveness and user experience.
🔍 What is INP and Why It Replaced FID
FID only measured the first interaction delay, which didn’t reflect the full user experience. INP, however, calculates the latency of the worst interaction, giving a far better snapshot of how responsive your site truly is.
✅ INP Thresholds for 2025:
| Performance Category | INP Value |
|---|---|
| Good | ≤ 200ms |
| Needs Improvement | 201ms – 500ms |
| Poor | > 500ms |

🧠 Why INP Matters for SEO and UX
- Google Ranking Signal: INP is now part of the Page Experience signal
- Real-World UX: INP catches slow interactions after page load, unlike FID
- Higher Engagement: Faster sites = lower bounce rates + more conversions
🛠️ How to Optimize INP in 2025
Here’s how you can stay ahead:
1. Reduce Long Tasks
Split large JavaScript tasks using setTimeout() or requestIdleCallback().
2. Minimize Main-Thread Work
Use Web Workers to offload intensive tasks from the UI thread.
3. Defer Non-Critical JavaScript
Defer analytics, widgets, and third-party scripts until after interaction.
4. Use Performance APIs
Leverage PerformanceObserver to track INP in real-time.
