The complete website redesign checklist: 20 steps for a smooth relaunch

EXECUTIVE SUMMARY

A website redesign fails in predictable places: rankings lost to missing redirects, scope creep from late feedback, and launch-day surprises nobody tested for. This 20-step checklist walks the full process in four phases: audit, plan, build and launch, with the SEO-protection steps that most DIY redesigns skip.

KEY INSIGHTS

  • Benchmark rankings and traffic before touching anything; you can’t protect what you haven’t measured.
  • Every old URL needs a 301 redirect to its closest new equivalent, no exceptions.
  • Design sign-off before build prevents the expensive kind of feedback.
  • Launch is a checklist, not a gamble; monitoring afterwards is part of the job.

Phase 1: Audit (steps 1 to 5)

1. Benchmark your current performance

Export current rankings, organic traffic, top pages and conversion numbers from Search Console and analytics. This baseline is how you’ll know the redesign worked, and how you’ll catch problems fast if it didn’t.

2. Audit your content

List every page and mark it: keep, improve, merge or retire. Pages that rank or earn links are assets; deleting them casually is how redesigns quietly torch years of SEO.

3. Inventory what ranks and why

Identify the pages bringing organic traffic and the keywords they hold. These pages get special handling: their content is preserved or improved, never thinned.

4. Map inbound links

Pages other sites link to carry authority. Note them; their URLs either survive or get redirected with care.

5. Diagnose the real problems

Be specific about why you’re redesigning: slow, dated, poor mobile, weak conversions? Our 12 warning signs guide helps separate causes from symptoms, so the new site fixes the right things.

Phase 2: Plan (steps 6 to 10)

6. Define measurable goals

“Look more modern” isn’t a goal. “Cut load time under two seconds, lift enquiries 30%” is. Goals decide design choices; without them everything is opinion.

7. Plan the new site structure

Map pages, hierarchy and navigation before designing anything. Structure is where UX is won, and changing it after build is the expensive way.

8. Build the redirect map

The single most-skipped step. Every old URL gets a 301 redirect to its closest new equivalent, per Google’s site-move guidance. Redirecting everything to the homepage doesn’t count; that throws relevance away.

9. Write content before design finalises

Design around real content, not lorem ipsum. Copy written after design gets squeezed into boxes it doesn’t fit.

10. Set the performance budget

Decide now: 90+ PageSpeed, loads around two seconds, accessibility to WCAG AA. Budgets set at the start get met; standards requested at the end get apologised for.

Rankings aren’t lost during redesigns. They’re lost during redesigns without redirect maps.

Phase 3: Build (steps 11 to 15)

11. Sign off design before build

Review and approve mockups first, the process covered in how designers work. Changing a mockup costs minutes; changing a built site costs days.

12. Build mobile-first on a staging site

The new site takes shape at a private URL while the live site keeps trading. Mobile layouts come first, because that’s where most visitors and Google’s index live.

13. Carry over and upgrade metadata

Title tags and descriptions from ranking pages are preserved or improved, never discarded wholesale. The same goes for schema markup.

14. Implement the redirects

Load the full 301 map onto staging and test a sample. This is also the moment to fix legacy redirect chains.

15. Test like a customer

Every form, on real phones. Every journey, end to end. Broken enquiry forms are the most expensive bug a business site can ship, and the least excusable.

Phase 4: Launch and after (steps 16 to 20)

16. Launch-day checklist

DNS, SSL, redirects live, analytics firing, forms delivering, XML sitemap submitted. Twenty minutes of checks; years of regret avoided.

17. Crawl the new site immediately

Run a crawler for broken links, missing titles and accidental noindex tags, the classic launch-day gremlin.

18. Watch Search Console daily for two weeks

Coverage errors and ranking wobbles show up here first. Small dips during reindexing are normal; trends aren’t, and early catches are cheap fixes.

19. Re-benchmark against step 1

At two, six and twelve weeks, compare rankings, traffic and conversions to your baseline. This is where the redesign proves itself in numbers, not opinions.

20. Move into maintenance

The relaunched site needs updates, security and monitoring to stay fast and safe, which is what a maintenance plan is for. A redesign is a reset, not a finish line.

Or have it done properly, once

This checklist is genuinely everything, and you’re welcome to run it yourself. It’s also precisely the process our website redesign service executes on every project, including the ranking-protection work that separates a relaunch from a restart. Redesigns are quoted bespoke and fixed before we start; tell us what you’re running and you’ll have a number within 48 hours.

Frequently asked questions

Will I lose rankings during a redesign?

Not if the audit, redirect and metadata steps are done properly. Expect minor fluctuation during reindexing; sustained drops mean a step was skipped, which monitoring catches early.

Can I keep my site live during the redesign?

Yes, that’s what staging sites are for. Your current site trades untouched until the new one is tested and ready to switch over, usually with zero downtime.

How often should a website be redesigned?

When the evidence says so, not on a calendar. Slow, mobile-hostile or under-converting sites are due; a well-maintained site can stay sharp for years. The 12 signs guide gives you the diagnostic.
