Speed audit + action plan

Every extra second of load time lowers conversion, and Google uses Core Web Vitals for ranking.

  • The list of real causes of slowness, ordered by gain relative to effort
  • Lost-sales estimate, calculated on your actual traffic

A migration quote given without looking inside your store is guesswork — on a decision worth tens of thousands of lei.

  • Analysis of the catalog, integrations and historical data to migrate
  • Proposed architecture and the concrete risks of your project
