FAQ

Shopify Development FAQs

Yes. We map handles/URLs, implement 301s, preserve canonical and schema, and validate in Search Console before and after launch.

We design and ship Functions for discounts and logic, configure B2B price lists/roles, and extend checkout safely.

We set budgets for LCP/CLS/INP, optimize images/fonts, minimize Liquid loops, and monitor CWV in CI.

Both. We build private apps and integrations to automate operations and unlock custom flows.
