Quick answer
A website redesign checklist covers four stages: before, planning, build and launch, and after. Record your current rankings and traffic, map every old URL to a new one with 301 redirects, test on real devices, check tracking and speed before launch, and monitor search and conversions for weeks afterwards.
This website redesign checklist covers what to audit, plan, test and monitor. A redesign can make a site look fresh and still quietly kill its traffic. It happens a lot. The new site launches, everyone loves the look, and three weeks later enquiries have dropped and nobody knows why.
The cause is almost always something that was changed without anyone noticing: URLs, page content, redirects, tracking. This checklist is how you avoid that.
Website redesign checklist, step 1: before the redesign
1. Decide why you are redesigning
Be clear about the goal. More enquiries? Better mobile experience? New brand? A platform that is easier to manage? The goal shapes every decision, and it gives you something to measure the result against.
2. Record how the current site performs
Before you change anything, save a snapshot:
- Organic traffic by page
- Pages that bring leads or sales
- Keyword rankings for important terms
- Conversion rate and the actions you track
- Page speed
Without this, you cannot tell afterwards whether the redesign helped.
3. List every page and its job
Export a list of all URLs. For each one, note whether it brings traffic, whether it has links from other sites, and what role it plays. Some pages will be worth keeping as they are. Others can be merged or retired.
4. Protect the pages that work
Pages that rank or convert are assets. Do not rewrite them from scratch without a reason. Keep the content that earned the ranking, and improve it carefully rather than replacing it.
Planning the new site
5. Plan the structure
Decide how pages will be organised, how navigation will work and how people will move toward a conversion. Aim for a structure that is simple for people and clear for search engines.
6. Keep URLs where you can
The cleanest approach is to keep the same URLs for pages that continue to exist. If you must change them, plan it carefully.
7. Map every redirect
For each old URL that changes or disappears, decide where it should go. Use permanent redirects (301s) to send visitors and search engines to the closest matching new page. Redirecting everything to the homepage is a common mistake and wastes the value of old pages.
| Situation | What to do |
|---|---|
| URL stays the same | Nothing, check it still works |
| URL changes | 301 redirect to the new URL |
| Page merged into another | 301 redirect to the merged page |
| Page retired with no equivalent | Redirect to the most relevant section, or let it return a proper not-found page |
8. Carry over metadata and content
Page titles, descriptions, headings, image descriptions and structured data all help pages rank. Make sure they come across to the new site, or are deliberately improved.
9. Plan for speed and mobile
New designs can bring heavy images, scripts and animations that slow pages down. Test performance on a phone and set limits before you build, not after.
10. Plan tracking
Make sure analytics, conversion tracking and ad tags are set up on the new site from day one. Test forms, phone clicks and bookings before launch.
During build and testing
11. Build on a staging site
Use a private test version that search engines cannot see. Block it from indexing so it does not compete with your live site. Remember to remove that block at launch, a surprisingly common slip.
12. Test everything
Check every form, link, menu, redirect and tracking event. Test on different phones and browsers. Click through the main journeys as a customer would.
Launch day
13. Launch at a quiet time
Pick a time with lower traffic and when your team is available to fix problems.
14. Check the basics immediately
- Redirects work and go to the right pages
- The site is allowed to be indexed
- The sitemap is updated and submitted
- Forms and phone numbers work
- Tracking records conversions
After launch
15. Watch for a few weeks
Check daily at first. Look at Google Search Console for crawl errors, indexing issues and sudden drops. Compare traffic and conversions with your snapshot.
16. Fix problems fast
Missing redirects, broken pages and slow load times are easier to fix quickly than after rankings have fallen.
17. Improve, do not stop
A redesign is a starting point. Keep testing and improving based on how real visitors use the site. If you are unsure whether it is time to start over, see seven signs it is time to redesign.
What do Google’s migration guides say?
Google documents the process, and the checklist above follows it. Site moves with URL changes explains how to move a site with URL changes: map old URLs to new ones, use server-side redirects and monitor the move. Redirects and Google Search covers redirects in detail, including why permanent redirects tell Google that a page has moved.
Speed and stability need testing before launch. Web Vitals describes the metrics Google uses to measure loading, interactivity and visual stability, and a redesign is the strongest moment to build them in.
Mobile matters too. Mobile-first indexing strongest practices explains that Google primarily uses the mobile version of a page for indexing, so the mobile site must have the same content and structured data as the desktop one.
Finally, make sure Google can read the new pages. Introduction to structured data markup in Google Search explains structured data, which you should re-test on the new templates.

When is a website redesign not the answer?
If your issue is that the site gets visitors but no enquiries, the cause may be the offer, the message or the follow-up, not the design. Read why your website gets traffic but no leads first.
For how we approach this, see our website service.
Keep a record of what you changed
Save the old site map and a list of the top pages, so you can compare after launch.

Frequently asked questions
Will a redesign hurt my SEO?
It can, mostly because of URL changes, missing redirects, removed content or slower pages. With careful planning, a redesign can also improve SEO. The key is to treat existing rankings as assets to protect. Plan redirects and content early, before any design work begins.
How long does it take to recover if rankings drop?
It depends on the cause and how fast you fix it. Missing redirects can often be repaired within days, and rankings may return within weeks. Deeper issues, like removed content, may take longer. Monitor Search Console weekly during recovery to confirm fixes are working.
Should I change my domain during a redesign?
Avoid it unless there is a strong reason. Changing the domain adds risk on top of everything else. If you must, plan the move carefully and use redirects from every old URL to the matching new one. Never change domain and design in the same step unless you must.
Will a redesign lower my search rankings?
It can if URLs change, content is removed or the site gets slower. Keep the pages that rank, redirect every old URL to its new equivalent and check the site before and after launch. Handled carefully, rankings usually recover or improve.
How long should a redesign take?
It depends on size and approvals. A small site can take weeks, and a larger one months. The biggest delays come from content and decisions, so settle copy, structure and sign-off early.
