Core Web Vitals & Site Speed
Faster pages, better rankings, fewer visitors bouncing before they see your content.
Core Web Vitals are a ranking factor, but more importantly, they're a proxy for whether real people can actually use your site. A slow, janky homepage loses customers regardless of what Google thinks.
I diagnose using real user data (CrUX field data), not just a lab score, then fix the actual bottleneck: bloated JS bundles, unoptimized images, render blocking resources, slow hosting, instead of chasing a Lighthouse number that doesn't reflect reality.
What's Included
- LCP, INP, and CLS diagnosis using field (CrUX) and lab data
- Image and font optimization audit
- JavaScript payload and third party script review
- Render blocking resource elimination
- Hosting and CDN configuration review
- Layout shift source mapping
- Before/after performance dashboard
Process
01
Baseline & Diagnose
Pull real user field data alongside lab tests to find where the actual bottleneck is, not just what Lighthouse flags.
02
Root Cause Triage
Every metric gets traced to its actual cause: a specific script, image, font, or server response.
03
Fix & Optimize
Implement fixes directly or spec them precisely for your dev team, in priority order.
04
Monitor & Confirm
Track field data for 2 to 4 weeks after the fix to confirm the improvement holds for real visitors, not just in a lab test.
Deliverables
- Performance diagnostic report
- Prioritized fix list by impact
- Before/after CWV dashboard
- Image/font/script optimization implementation
FAQs
A high lab score doesn't guarantee good field data. Real users on real networks and devices often see a very different picture, which is what actually affects rankings and conversions.
Rarely. Most Core Web Vitals issues are fixable at the asset/code level without touching the design.
Technical fixes show in lab tools within days; field data (what Google actually uses) takes 2 to 4 weeks to reflect the change.
Yes, mobile performance is weighted more heavily and is diagnosed and optimized separately from desktop.
