FREQUENTLY ASKED QUESTIONS

Website Revamp & Modernization FAQs

Answers to common technical, pricing, and timeline questions regarding our Website Revamp & Modernization services.

Will our existing Google SEO rankings drop during a website revamp?
No. We implement a rigorous SEO preservation strategy including complete 1:1 URL 301 redirect mapping, exact canonical tag preservation, semantic heading retention, and live Google Search Console monitoring so your search rankings and domain authority remain protected.
How long does a typical corporate website revamp take?
Standard corporate revamps typically take 3 to 6 weeks depending on page count and custom functionality. Staging is completed in weeks 2–4, followed by content migration, SEO verification, and a zero-downtime cutover.
Will our current website experience any downtime while you work?
None whatsoever. All development, testing, and staging happen in an isolated development environment. Your live website remains 100% operational until DNS propagation takes place during an off-peak maintenance window.
Can we migrate our existing content, blogs, and customer data to the new design?
Yes. We perform automated database extraction and migration for all existing blog posts, client testimonials, case studies, and media libraries, ensuring all your valuable content transitions seamlessly into the new modern design.
What happens if we need custom functionality like portal logins or CRM integrations?
Our engineering team specializes in custom full-stack integrations. We can rebuild your customer portals, quote calculators, CRM webhooks (HubSpot, Salesforce, Zoho), and payment gateways as part of the revamp process.
