Core Web Vitals for business owners
By FloPixels Team · Published June 1, 2026 · Updated July 20, 2026
LCP, INP, and CLS explained in plain English, with Google's current good thresholds.
What Core Web Vitals measure
Three user-experience signals: how quickly the main content loads (LCP), how quickly the page responds to interaction (INP), and how much the layout shifts unexpectedly as it loads (CLS).
The current good thresholds
- LCP ≤ 2.5 seconds
- INP < 200 milliseconds
- CLS < 0.1
What most often causes failures
- Large unoptimized hero images
- Blocking third-party scripts
- Fonts loaded without size reservation
- Ads or embeds injected after render
What to ask your team
Which pages fail thresholds, on which devices, and what's the top fix planned for each?
Key takeaways
- Three signals, three thresholds
- Images and third-party scripts cause most failures
- 75th percentile, real users—not lab tests—is what Google uses
