A website redesign checklist needs to do one thing above all: prevent the 40 percent traffic drop that hits most redesigned sites in the first 90 days. Design matters, but losing your organic rankings matters more.

We have led 60+ redesigns. Every single one that skipped the SEO prep lost traffic. Every one that followed a checklist like this held or grew it.

Phase 1: Pre-Redesign Baseline (Week 0)

Before anyone opens Figma, capture what you have.

1. Full site crawl

Screaming Frog or Sitebulb. Export every URL, title, H1, meta, and status code. Save two copies.

2. Search Console export

16 months of query data, page-level clicks, impressions, and positions. CSV export.

3. Analytics baseline

Last 12 months of GA4: sessions, users, conversions, top landing pages, top exit pages.

4. Rank tracking snapshot

Top 50 keywords with current positions. Use a free tool or screenshot SERP positions manually.

5. Backlink inventory

Top 200 backlinks from Ahrefs free tier or Search Console Links report.

6. Current page speed

PageSpeed Insights on homepage and top 5 pages. Record LCP, INP, CLS.

Without this baseline, you cannot tell if the redesign helped or hurt.

Phase 2: Strategy and Structure

7. Define the goal

“Look better” is not a goal. “Increase demo requests by 30 percent” is. Without a measurable goal, you will optimize for the designer’s portfolio, not your business.

8. Information architecture

Map the new site structure BEFORE designing any page. Use our website cost calculator to pressure-test scope.

9. URL mapping

Spreadsheet columns: old URL, new URL, 301 redirect (Y/N), priority. Every URL getting changed needs a 301 planned.

10. Content audit

Keep what converts. Consolidate the thin. Delete the dead. Our site audit guide details the process.

11. Preserve your top pages

Top 20 pages by traffic and conversions should keep their URLs if at all possible. Change the design, not the URL.

Phase 3: Design

12. Mobile-first wireframes

Design for 375px width first, not 1440px. Read our mobile-first design principles guide.

13. Core Web Vitals budget

Set budgets before building: LCP under 2.5s, INP under 200ms, CLS under 0.1. Our website speed optimization post covers how to hit these.

14. Brand consistency

Colors, fonts, voice. Document in a 1-page style guide before any page design begins.

15. Accessibility

WCAG 2.2 AA contrast ratios, focus states, keyboard navigation. Non-negotiable.

16. CTAs and conversion points

Every page needs a purpose. What does the user do next?

Phase 4: Development and SEO Prep

17. Staging environment with noindex

Never let Google index your staging site. Either password-protect it or noindex every page.

18. Preserve title tags and meta descriptions

Unless you are rewriting for clear improvement, keep them. They took years to earn their CTR.

19. Preserve heading structure

One H1 per page, matching search intent.

20. 301 redirect map ready to deploy

Not “we will figure it out after launch.” Ready to push on launch day.

21. Schema markup planned

LocalBusiness, Organization, Article, Product, FAQ, as applicable.

22. XML sitemap generated

Submit to Search Console on launch day.

23. Robots.txt reviewed

Remove any stray Disallow that blocks the whole site.

24. Canonical tags

Every page needs a self-referencing canonical.

25. Internal linking preserved

Rebuild your hub-and-spoke structure in the new site.

Phase 5: Pre-Launch QA

26. Crawl the staging site

Check for 404s, redirect chains, missing titles. Fix before launch.

27. Test all forms

Every form. Submit a test. Check the inbox and the CRM.

28. Test on real devices

iPhone SE, iPhone 15, Android mid-range, iPad, Windows laptop. Not just Chrome DevTools.

29. Run the speed test

PageSpeed Insights on 10 pages. Fix any failing before launch.

30. Accessibility audit

WAVE browser extension or axe DevTools. Fix critical issues.

31. Analytics installed and tested

GA4 firing, events working, conversions tracked, consent mode active.

32. Search Console property verified

For the new domain or protocol if applicable.

Phase 6: Launch

33. Pick a low-traffic day

Tuesday or Wednesday morning, not Friday afternoon.

34. Deploy the 301s

Minute one. Every old URL pointing to its new home.

35. Submit the new sitemap

Search Console > Sitemaps > Submit.

36. Request indexing for top 20 pages

URL Inspection > Request Indexing, one by one.

37. Monitor errors

Search Console Coverage, server logs, and Sentry or similar.

Phase 7: Post-Launch

38. Daily checks week 1

Traffic, conversions, crawl errors, redirect chains. Fix same-day.

39. Weekly checks month 1

Rankings drift, new 404s, Core Web Vitals, conversion rate trend.

40. Compare to baseline at 30 days

Traffic should be within 10 percent of pre-launch. If down 15 percent or more, dig in.

41. Compare at 90 days

Recovery window closes here. If still down, you missed something big. Audit again.

42. Post-mortem

What worked, what did not, what to do differently next time.

Common Disasters and How to Avoid Them

• No 301 redirects: 50 percent traffic loss in 2 weeks. Deploy redirects WITH the launch.
• Changed URLs without mapping: similar outcome. Map every URL.
• Shipping the staging site to production without noindex removal: Google deindexes the whole site.
• Launching on Friday: no one to fix Saturday’s crisis.
• Ignoring Core Web Vitals: new site loads slower than old site, rankings drop.

Getting Help

Redesigns are the single riskiest project a marketing site runs. If stakes are high, get experienced help. Our website design services include SEO migration as a default deliverable, not a paid add-on.

FAQ

How long does a website redesign take? A 30-page marketing site takes 8 to 14 weeks end to end. A 200-page site with custom functionality takes 4 to 6 months. Rushing under 8 weeks almost always means skipped SEO prep or QA. The redo costs more than the extra month would have.

Do I lose rankings during a redesign? Not if the checklist is followed. Expect a 10 to 20 percent dip for 2 to 4 weeks as Google re-crawls and re-ranks, then recovery to baseline by week 8. Anything worse means 301s were missed or content/structure changed too aggressively.

Should I redesign all at once or section by section? Big sites: section by section. Small sites: all at once. Sectional rollouts reduce risk but triple the timeline. Under 50 pages, do it all in one coordinated launch with a full 301 map in place.

What is the most common redesign mistake? Changing URLs without 301 redirects. Followed by removing pages that drove organic traffic because “no one visited them from the homepage.” Organic landing pages rarely show up in the menu. Check Analytics before deleting anything.
