Core Web Vitals Ready

Performance Optimization for Public Administration(Core Web Vitals)

We'll speed up your website to meet Core Web Vitals goals and ensure smooth operation even on slower devices and networks. We focus on LCP, INP, CLS, as well as TTFB, rendering elements, JS/CSS size, cache, and database.

LCP ≤ 2.0s

Largest Contentful Paint

INP ≤ 200ms

Interaction to Next Paint

CLS ≤ 0.10

Cumulative Layout Shift

The result is faster loading, better UX and higher service availability

Performance optimization brings measurable results for your users and your organization

Faster Loading

Meeting Core Web Vitals goals for better user experience and SEO positions.

Better UX

Smooth operation even on slower devices and networks.

Higher Availability

Optimization for all types of devices and network conditions.

Better SEO

Core Web Vitals are an important factor for Google ranking.

Mobile Optimization

Focus on mobile devices where performance is most critical.

Measurement and Monitoring

Ongoing performance monitoring with alerts and reports.

In addition to performance, we also check accessibility and security headers

Success Metrics (Goals)

Concrete goals for Core Web Vitals and other key performance metrics

Core Web Vitals Goals

LCP (Largest Contentful Paint)

≤ 2.0s

Critical images/hero blocks, server response time, image formats (AVIF/WebP), preload/fetchpriority.

INP (Interaction to Next Paint)

≤ 200ms

Reducing JS load, input prioritization, event batching, list virtualization, idle tasks.

CLS (Cumulative Layout Shift)

≤ 0.10

Dimension reservation (images/iframes), stable fonts (FOIT/FOUT), predictable ads/embeds.

TTFB (Time to First Byte)

-20-40%

Edge cache/CDN, compression (Brotli), HTTP/2/3, query and rendering optimization.

What We Optimize

Networks and Cache

  • HTTP cache headers
  • stale-while-revalidate
  • CDN layers
  • Cache policy for HTML vs. assets

Images and Video

  • Multiple size generation
  • srcset/sizes
  • Lazy‑loading
  • Poster for video

JavaScript and CSS

  • Code‑splitting
  • Tree‑shaking
  • Defer non-critical
  • Critical CSS
  • Framework overhead minimization

Database (CMS)

  • Indexes
  • Query cache
  • Object cache
  • Heavy query limitation

Additional optimization goals

-30-60%

JS size vs baseline

-20-40%

TTFB based on hosting

95%

Mobile p95 metrics

Methodology

Systematic approach to performance optimization with measurable results

Measurement

WebPageTest/LH lab + RUM (real data) where available.

Analysis

Identification of top bottlenecks on LCP/INP/CLS, impact weight × cost.

Design

Performance roadmap, performance budgets (KB, ms, requests).

Implementation

Iteratively (quick wins → templates → systemic changes).

Validation

Repeated tests (lab + RUM), regression monitoring in CI.

Monitoring

Ongoing monitoring, alerts and monthly reports.
