Frequently asked questions.
Why is my Shopify store slow?
Three causes cover most cases: a bloated theme with 20+ apps each loading 100KB of JavaScript; unoptimised images served at full resolution; and third-party scripts loading synchronously. A proper audit separates them.
How long does speed optimization take?
The standard engagement is 4–5 weeks: audit, quick wins, deep optimization, verification. A two-week sprint version exists for urgent cases.
Why do Core Web Vitals matter?
Google uses them as a ranking signal, especially on mobile. More importantly they move revenue: stores with LCP under two seconds convert measurably better than those above four.
Will it stay fast afterwards?
Only if it is watched. Adding apps or updating the theme can undo the work, which is why our retainer includes monitoring with an automatic alert when performance regresses more than 10%.
