A perfect Lighthouse score on your laptop tells you very little. What matters is field data from real customers on real phones, and on most Shopify stores the largest cost is not the theme but the accumulated weight of apps nobody has audited in two years.
What's included
App script audit
Every third-party script measured for weight and blocking cost, with a recommendation to keep, defer, or remove. This is usually the biggest single win available.
Image and font strategy
Correct sizing, modern formats, and font loading that does not shift the layout under the reader.
Render path work
Critical CSS, deferred non-essential JavaScript, and reserved space for late-loading elements to eliminate layout shift.
Regression protection
A performance budget in CI, so the next app install cannot quietly undo the work.
