Shopify Performance Optimization, End to End
A repeatable audit for Liquid, third-party scripts, and Core Web Vitals — and the conversion lift that follows.
Most Shopify performance problems are not the platform. They are third-party scripts, unoptimised media, and Liquid that loops where it should query.
Audit in this order: field data first, then lab data, then code. Real-user Core Web Vitals tell you which templates actually matter to revenue.
Tame the tag manager. Defer non-critical tags, remove duplicates, and put a review gate on new pixels — marketing tags are the most common cause of regression.
Optimise the LCP element deliberately: correct image sizing, preload the hero, avoid client-side rendering for above-the-fold content.
Then measure the conversion delta, not just the score. Performance work earns its budget by proving commercial impact.
