Core Web Vitals Optimization

Stop losing customers to a slow website.

A 1-second delay in page load time reduces conversions by 7%. I rewrite bloated frontends and configure edge networks to guarantee sub-2-second load times.

The Difference

The difference between bouncing and buying.

Actual results from a recent Shopify headless migration.

Before Audit
32 Lighthouse Score
First Contentful Paint 4.2s
Time to Interactive 8.1s
Cumulative Layout Shift 0.45
After Optimization
99 Lighthouse Score
First Contentful Paint 0.8s
Time to Interactive 1.1s
Cumulative Layout Shift 0.01

Recent result: a Shopify Plus store reduced Time to Interactive from 8.1s to 1.1s after stripping third-party app bloat and implementing edge caching. Measured with Lighthouse on mobile, before and after the engagement.

The Diagnosis

Why your current setup is failing Core Web Vitals.

01

Bloated JavaScript

Most themes load every single script on the initial page load. We defer non-critical JS and implement strict code-splitting to free up the main thread.

02

Unoptimized Assets

Serving 5MB uncompressed PNGs kills mobile performance. We migrate assets to modern formats (WebP/AVIF) and serve them via advanced Edge CDNs.

03

Third-Party App Bloat

Shopify and WordPress plugins inject tracking codes that block rendering. I audit, consolidate, and asynchronously load your marketing stack.

Same Pattern, Different Platform

The Shopify example above isn’t a one-off.

WooCommerce, Norway

MerkBart moved off shared hosting onto AWS Lightsail with S3 + CloudFront for uploads.

The admin panel used to freeze for minutes on every order with multiple logo uploads. Now it doesn’t freeze at all, and pages load roughly 4× faster.
