What Core Web Vitals improvement should I expect?

Stores starting in the red typically reach green. Stores in the amber band usually see LCP improvements of 30 to 50 percent. We share the realistic target after the baseline is captured.

Will you tell me which apps to remove?

We surface the perf cost of every app. You decide what to remove based on business value. Marketing and ops sign-off before any removal.

Image optimisation, what changes exactly?

Format migration to AVIF / WebP, lazy-loading on below-fold images, proper srcset for responsive images, and removing the manual asset uploads that bypass Shopify CDN.

What about the Shopify CDN?

Shopify CDN is fast but theme code can defeat it. We audit the cases where developers have bypassed the CDN with hardcoded asset URLs or external image hosts.

Is the improvement permanent?

Yes until your team adds something that regresses it. The re-runnable test config lets your team catch regressions before they ship. Most stores book a quarterly re-baseline as a small retainer.

Optimisation de la vitesse Shopify

Optimisation de la vitesse Shopify. LCP, INP, CLS, taille du bundle de thème, audit d'application, optimisation des images. Core Web Vitals au vert.

Timeline: 2 to 4 weeks
Headline: Core Web Vitals
Measurement: Pre + post baseline
Handover: Re-runnable tests

Overview

What it is.

Optimisation de la vitesse pour les boutiques Shopify. Audit du bundle de thème, analyse des coûts de performance des applications, optimisation des images, améliorations du chemin de rendu. Le résultat est une amélioration vérifiée des Core Web Vitals sur les cinq surfaces les plus mesurées par rapport à une ligne de base que nous capturons avant le début des travaux. La plupart des engagements durent de 2 à 4 semaines, de la ligne de base à l'amélioration vérifiée. Les thèmes avec des piles d'applications étendues peuvent s'étendre jusqu'à 6 semaines.

What you get

Deliverables.

Pre-engagement baseline (Lighthouse + WPT + CrUX)
Theme bundle size analysis with extraction plan
App perf-cost audit (which app costs how much)
Image optimisation (format, lazy-load, sizing)
Render-blocking JS and CSS extraction
Liquid render-loop optimisation
Post-engagement baseline with delta report
Re-runnable test config handed to your team

Honest limits

What it isn't.

Theme architecture changes beyond standard optimisation are quoted separately
Apps we recommend removing need your marketing and ops sign-off
Shopify-platform performance changes are outside our control
