A: WordPress page builders and Webflow sites accumulate large JavaScript bundles and heavy DOM structures, often causing mobile page load times of 3 to 5 seconds and lower Google search rankings. Astro delivers pre-rendered HTML with zero client-side JavaScript by default, guaranteeing sub-100ms response times, 100/100 Core Web Vitals, and maximum conversion rates. ### Q: Can our marketing team edit content without writing code? A: Yes. We integrate headless CMS platforms like Sanity, Storyblok, or Decap CMS. Your marketing team gets an intuitive visual editor to publish blog posts, update copy, and create new landing pages without touching code. ### Q: How do you ensure zero Cumulative Layout Shift (CLS)? A: We specify explicit aspect ratio dimensions on all images and video containers, self-host optimized WOFF2 fonts with size-adjusted fallback metrics, and pre-render critical CSS to eliminate layout jumping. ### Q: Will our organic Google search rankings drop during a website redesign? A: No. We implement a strict 1-to-1 URL migration plan, preserve existing metadata, set up comprehensive 301 redirects, and expand Schema.org structured data to protect and boost your organic search equity. ### Q: How long does a bespoke corporate website project take? A: A complete custom B2B website project, including information architecture, bespoke design, headless CMS integration, and technical SEO tuning, is typically completed within 3 to 6 weeks. - Services Catalog: https://fixrweb.com/services/index.md - Internal Tool Building: https://fixrweb.com/services/internal-tools.md - Custom Application Development: https://fixrweb.com/services/custom-apps.md - Managed Cloud Hosting: https://fixrweb.com/services/managed-hosting.md - AI Master Index: https://fixrweb.com/llms.txt
