Performance & Core Web Vitals – every second counts.
Performance is visibility today: Google uses Core Web Vitals (LCP, INP, CLS) as a ranking signal, and users abandon slow pages within seconds. We move your performance into the green zone.
- LCP < 2.5 s
- INP < 200 ms
- CLS < 0.1
- Lighthouse ≥ 90
Core Web Vitals optimization makes your website faster and more stable: better LCP, INP and CLS scores improve rankings and lower bounce rates – because every second of load time costs conversions.
Core Web Vitals in the green
Speed, responsiveness and stability are ranking factors. We get your site past all three thresholds – measured on real devices.
Six performance areas
Server & hosting
TTFB, HTTP/3, edge caching, CDN configuration.
Image pipeline
Modern formats (AVIF/WebP), responsive sizes, lazy loading.
JS & CSS
Bundling, code splitting, critical path, tree shaking.
Fonts
Self-hosting, subsetting, font-display: swap.
Third parties
Analytics, chat widgets, pixels – server-side or lazy.
Layout stability
CLS optimization via predefined image/banner heights.
The key questions, answered briefly
What are good Core Web Vitals scores?
Google recommends: LCP under 2.5 seconds, INP under 200 milliseconds and CLS under 0.1. When these thresholds are met on mobile, the page counts as fast – an advantage for ranking and user experience.
Why is my website slow?
Common causes are large, uncompressed images, too much JavaScript, slow hosting, missing caching and render-blocking resources. A performance analysis prioritizes the causes with the biggest impact first.
What are good Core Web Vitals scores?
Google recommends clear thresholds on mobile: LCP under 2.5 seconds, INP under 200 milliseconds, CLS under 0.1. When they're met, the page counts as fast and stable – an advantage for ranking and conversion.
| Metric | Good | Needs improvement | Poor |
|---|---|---|---|
| LCP (load time) | ≤ 2.5 s | 2.5–4 s | > 4 s |
| INP (responsiveness) | ≤ 200 ms | 200–500 ms | > 500 ms |
| CLS (stability) | ≤ 0.1 | 0.1–0.25 | > 0.25 |
Why is my website slow?
Usually not the server, but avoidable bottlenecks. The most common causes – and what we look at first:
Common questions
How quickly do we see improvements?
First effects often within 1–2 weeks. Google typically integrates changed scores within 28 days.
Do we need a new host?
Sometimes – if TTFB is chronically above 1 s. Otherwise caching and CDN optimization usually suffice.
What is INP?
Interaction to Next Paint – it measures how quickly the page responds to clicks. It replaced the older FID metric in March 2024.
