The Ultimate SEO Checklist for Website Redesigns & Migrations

Redesigns can make or break a site; done right, they boost traffic and UX. Done wrong, they can harm SEO and rankings. Plan SEO from day one, with your team or an agency in India or Kochi offering website migration SEO services.

Why SEO Is Key in Redesigns & Migrations

Design, platform, domain, or site architecture changes affect SEO and users.

Without SEO, you risk:

• Losing high‑value rankings and organic traffic
• Breaking key pages with 404 error pages and redirect loops
• Diluting or losing link equity due to poor 301 redirects.
• Confusing crawlers with messy URL mapping and duplicate content​

SEO-first protects and grows your site.

Redesign & Migration SEO Checklist

Use this as a practical checklist. Ideally, your SEO, dev and design teams (or your web designing company in Kochi) work through it together in a staging environment.​

1. Pre‑Migration: Audit and Plan

• Export top pages—your “do not break” URLs.
• Document current site architecture and key templates.
• Build a detailed URL mapping sheet from old URLs to new URLs to retaining link equity.​
• Prioritise content that must be migrated as‑is, updated, merged, or retired.

2. Work on a Staging Site

Never test live. Always build and review the new site in a staging site that is blocked from indexing (via password protection or noindex).​

On staging:

• Ensure SEO-friendly structure, preserve on-page basics.
• Test mobile and Core Web Vitals early.

3. Redirects and Error Handling

Redirects often fail during migrations.

• Use one-to-one 301 redirects.
• Keep redirects clean and simple.
• Make helpful 404 pages with search and links.
• Update internal links to new URLs.

4. Technical SEO Checks at Launch

On launch day, run a quick technical audit.

• Remove any noindex / password protection used on the staging site.
• Check robots.txt, sitemaps, and canonicals.
• Verify analytics and tracking on key templates.

5. Post‑Migration Monitoring

The work does not stop at launch.

• Track key page rankings and traffic.
• Fix 404 errors with new content.
• Review performance after 2–4 weeks and 2–3 months.

Common SEO Mistakes to Avoid

Redesigns and migrations often face common mistakes:

• Redesigning purely for look and feel, ignoring SEO data
• Changing URL structure without proper URL mapping and 301 redirects
• Launching the new site without crawling it or doing a technical audit
• Forgetting to migrate or rewrite high‑performing content
• Not involving SEO until just before launch (or worse, after traffic drop)
• Overlooking 404 error pages and broken internal links
• Failing to monitor post‑launch performance and assuming “no news is good news”

Avoiding these is half the battle.

Why Professional SEO Services Help (Especially in India & Kochi)

Redesigns and migrations are complex. Having a specialist team manage website migration SEO services can save time, revenue, and stress—especially if your in‑house team is small.​

A good partner offering SEO services in India or the best SEO services in Kochi can:

• Lead the technical audit and pre‑migration planning
• Own URL mapping, 301 redirects and error handling
• Collaborate with your web designing company in Kochi or web designing company in India on site architecture and UX​
• Build dashboards to track rankings, traffic and conversions before and after launch
• Troubleshoot issues quickly if a traffic drop or crawl problem appears
