Is this only a Lighthouse audit?
No. Lighthouse is useful, but we care more about real users, production traces, page weight, third-party behavior, caching, and the code paths behind the score.

Where this helps
Core Web Vitals, observabilité et le travail ingrat qui empêche un lancement de tourner à l'incident. La vitesse est une fonctionnalité ; rester en ligne est le produit.
Use this when speed, uptime, and stability are starting to affect conversions, SEO, launch confidence, or support volume. We find the bottlenecks, fix the causes, and leave monitoring behind.
Voir des réalisations liéesWhat gets better
- 01
Measurable Core Web Vitals gains
We prioritize LCP, INP, CLS, and real-user metrics instead of chasing lab scores that do not move the business.
- 02
Fewer hidden failure modes
Errors, slow endpoints, third-party scripts, and cache misses become visible before they become customer complaints.
- 03
A faster path to confident launches
Budgets, monitoring, rollback thinking, and post-launch checks make performance part of delivery, not cleanup.
What's included
Core Web Vitals
LCP, INP, and CLS measured, budgeted, and driven down.
Audits & profiling
Real-device profiling that finds what's actually slow, not what looks slow.
Caching & delivery
CDN, caching, and image strategy tuned for a fast first paint.
Monitoring & SLOs
Uptime, error budgets, and alerts that keep a launch calm.
Good fit
Performance work is strongest when it connects technical improvements to visible user, revenue, SEO, or reliability goals.
Best when
Pages feel slow, Core Web Vitals are weak, search traffic matters, or launches need better monitoring.
Not ideal when
You want a one-off score screenshot without changing code, infrastructure, content, or third-party scripts.
You leave with
A prioritized audit, shipped fixes, budgets, dashboards, and guidance to keep regressions from returning.

Service questions
The short answers buyers usually need before a scoping call.
Can performance work help SEO?
It can. Faster pages, better Core Web Vitals, cleaner rendering, and more stable content help search engines crawl and evaluate the experience.
How do you stop regressions?
We leave budgets, monitoring, alerts, and review habits in place so new images, scripts, and features are checked before they quietly slow the site down.
