Website Redesign & Optimization — Audit, Improve, Perform

Your site already exists but it's slow, poorly ranked, or visually outdated? A redesign or targeted optimization can transform your performance without starting from scratch. I audit, diagnose, and improve websites.

Why redesign or optimize your website?

A website has a lifespan. If your site is 3-4 years old, it's likely slow, poorly ranked on mobile searches, and visually outdated. A redesign or targeted optimization can transform results without starting from scratch.

What a site audit covers

  • Technical audit — Page speed (Core Web Vitals), 404 errors, HTTPS, crawlability
  • SEO audit — Keyword rankings, indexed pages, backlink profile, URL structure, meta tags
  • UX audit — Bounce rate, user journeys, call-to-action clarity
  • Competitor analysis — Benchmarking against sites ranking for your target keywords

Optimization without full redesign

Sometimes targeted improvements are enough:

  • Image optimization (WebP, lazy loading)
  • Core Web Vitals fixes (LCP, FID, CLS)
  • Schema.org structured data
  • Internal linking improvements
  • Title and meta description optimization

Full website redesign

For sites needing a complete overhaul, I manage the entire project: audit, content strategy, design, development in Next.js, 301 redirects to preserve SEO, and post-launch monitoring.
