frequently_asked()

01How fast can Shopify stores realistically go?

Lighthouse 90+ on mobile is achievable on most themes. The ceiling on Shopify is lower than on self-hosted stacks because of CDN constraints and mandatory third-party scripts, but passing Core Web Vitals is always the realistic goal.

02Will optimisation break my apps or theme?

No. Every change is tested on a duplicate theme before going live. Checkout, product pages, and payment flows get full regression checks. We only publish after you approve the before/after report.

03What's your approach to third-party app performance?

We audit every app for performance impact. Unused apps get removed. Necessary-but-heavy apps get deferred, lazy-loaded, or replaced with a lighter alternative. We show you the cost of each app in milliseconds.

04Do you optimise checkout speed?

On Shopify Plus yes, via Checkout Extensibility and checkout.liquid tuning. On lower tiers checkout is largely locked down, so we focus on the pre-checkout funnel which is where 80% of drop-off happens anyway.

05How long does a Shopify speed rescue take?

Standard engagements wrap in 5 business days. Complex stores with heavy app stacks or custom code can run 7 to 10 days. Timeline is fixed in your quote.

06Will this work with any Shopify theme?

Yes. We've rescued Dawn-based builds, vintage themes, Shopify Plus custom themes, Turbo, Impulse, Prestige, Debutify, and heavy-drag-and-drop builders. Every theme has levers. We find yours.
