Frequently Asked Questions
Web Architecture & Engineering FAQs
Transparent insights into Next.js edge migration, headless CMS workflows, SEO preservation, and code ownership.
Why should we migrate from WordPress or monolithic CMS platforms to Next.js 15?
Traditional WordPress sites rely on server-side PHP execution and dozens of third-party plugins that bloat client payloads, create security vulnerabilities, and result in slow 3–5 second page loads. Next.js 15 decouples the frontend from content management: pages are compiled at the edge with React Server Components, delivering instant sub-second loading, zero database attack surface, automated SEO metadata, and 99+ Core Web Vitals that significantly boost Google search rankings.
How does a headless CMS like Sanity or Strapi empower marketing teams?
In legacy CMS platforms, making design tweaks or assembling new pages requires developer intervention or clunky plugins that break site layouts. Headless CMS platforms like Sanity and Strapi provide modular, drag-and-drop page builders constrained by your exact design system tokens. Marketers can assemble on-brand landing pages in minutes, preview edits in real time side-by-side, and publish globally in under 5 seconds with zero risk of breaking styles.
Will a full website redesign cause our current Google search rankings or organic traffic to drop?
No. We implement a strict SEO preservation protocol throughout the redesign. We crawl and catalog 100% of your historical URL routes, map comprehensive 301 redirects, preserve existing schema markup and heading hierarchies, and enhance on-page performance metrics. In fact, our clients routinely experience immediate 20% to 45% organic traffic gains post-launch due to dramatic Core Web Vitals speed improvements.
Do we retain 100% intellectual property and code ownership of our new website?
Yes. Unlike many agencies that lock clients into proprietary hosting retainers or encrypted themes, Qualtriq provides complete, unencumbered ownership of all custom design files (Figma) and codebases (Git repositories). You can host anywhere (Vercel, AWS, Cloudflare, or your private cloud) with zero vendor lock-in.
How do your sub-second page loads directly improve our marketing conversion rate?
Independent research from Google and Akamai demonstrates that every 100ms reduction in page load latency yields an average 8% lift in conversion rates. Slow loading triggers immediate mobile visitor drop-off. By serving edge-rendered HTML in under 800ms with zero layout shifts, our clients routinely see bounce rate reductions of 30% to 50% and conversion rate increases of 35% or more across paid advertising and organic search.
What is your typical project timeline from discovery to production launch?
Our standardized enterprise web delivery framework spans 8 weeks: UX wireframing and content architecture in weeks 1–2, design system and high-fidelity UI in weeks 3–4, full-stack Next.js 15 edge engineering in weeks 5–6, and headless CMS integration, Lighthouse 99+ optimization, and launch in weeks 7–8.
