A website redesign SEO checklist protects the rankings you have already earned when you change design, platform, URLs or domain. The core steps are: benchmark current performance, crawl and inventory every existing URL, map each old URL to its new equivalent, set up 301 redirects, carry over titles, meta descriptions, content and schema, test the staging site, then launch, resubmit your sitemap in Google Search Console and monitor traffic, rankings and errors for at least eight weeks.
Skip any of those and a fresh new website can quietly lose half its organic traffic in a fortnight. We have seen it happen to Auckland businesses whose previous redesign removed every service page that ranked. The checklist below is the process we follow on every redesign, written so you can use it yourself or hold your developer to it.
Why redesigns lose rankings
Google ranks pages, not websites. When a redesign changes the address of a page that ranks, Google sees the old page disappear and a new, unknown page appear. Without a redirect, the ranking, backlinks and history attached to the old URL are lost. The most common causes of post-launch traffic drops are:
- Old URLs returning 404 errors instead of redirecting.
- Pages with rankings removed or merged without a plan.
- Content cut back to make the new design look clean.
- Titles, headings and meta descriptions rewritten without keyword research.
- The staging site's "noindex" setting left on at launch.
- Internal links pointing to old URLs or broken pages.
- Schema markup and analytics tags dropped in the rebuild.
Key point: design changes rarely hurt SEO on their own. Lost URLs, lost content and technical mistakes at launch do.
Website redesign SEO checklist: before you start
Work through these steps before design begins, because the URL plan affects the site structure.
Benchmark current performance
Export the last 12 to 16 months of data from Google Search Console (queries, pages, clicks, impressions) and your analytics platform. Note top landing pages, conversions by page and current rankings for your most valuable keywords. This is your baseline to measure the new site against.
Crawl the existing site
Use a crawler such as Screaming Frog to list every URL, status code, title, meta description, H1, canonical tag and word count. Combine it with URLs from Search Console, analytics and your XML sitemap, because crawlers miss orphaned pages that still get traffic.
Identify pages that matter
Flag every URL that has organic clicks, backlinks, conversions or rankings. These are the pages you must keep, improve or redirect carefully. Pages with no traffic and no links can be consolidated or dropped.
Build the URL map
Create a spreadsheet with every old URL in one column and its new destination in the next. Redirect each page to its closest equivalent, not to the homepage. Keep URLs unchanged wherever they already work, since the safest redirect is the one you do not need.
Plan content carry-over
For each page that ranks, keep the core content and the topics it covers. You can improve the writing, but removing sections that answer real search queries is one of the fastest ways to lose rankings.
During the build
Block staging from Google
Password-protect the staging site, or use noindex. Password protection is safer because it also keeps the staging copy out of search results entirely. Add a launch-day task to remove it.
Carry over and improve metadata
Transfer title tags and meta descriptions for every important page, then improve them where keyword research shows a better target. Keep one H1 per page that matches the page's main topic.
Rebuild internal links
Plan navigation and in-content links so key service pages receive links from related pages. Update every internal link to point straight at the new URL, not through a redirect.
Add schema markup
Implement structured data that matches the page type: LocalBusiness or Organization on the homepage, Service on service pages, Article on blog posts, FAQPage where suitable and BreadcrumbList across the site. Validate it with Google's Rich Results Test.
Check speed and mobile usability
Test key templates on a real phone and in PageSpeed Insights. A redesign is the cheapest moment to fix slow images, heavy fonts and bloated plugins. See our guide to website speed and Core Web Vitals.
Set up redirects on staging
Load the 301 redirect map and test every row. Each old URL should return a single 301 to the correct new page with a 200 status. Avoid redirect chains (A to B to C) and loops.
Launch day checklist
Launch on a quiet weekday morning rather than Friday afternoon, so issues can be fixed while people are around.
- Remove password protection and any sitewide noindex tag
- Check robots.txt is not blocking the site
- Confirm HTTPS works on every page, with HTTP and non-www versions redirecting to one canonical version
- Run the full redirect list through a crawler and fix any 404s or chains
- Check canonical tags point to the live URLs, not staging
- Submit the new XML sitemap in Google Search Console
- Confirm analytics, conversion tracking and call tracking are firing
- Update the website link on your Google Business Profile and key directory listings if any URLs changed
- Test every form, click-to-call link and checkout
If you are changing domain as well, use the Change of Address tool in Search Console after redirects are live. Google's documentation on site moves with URL changes is the authoritative reference for this process.
Post-launch monitoring: the first eight weeks
Most redesign problems show up in the data before they show up in the phone going quiet. Check these regularly.
Week one
- Search Console Pages report for new 404s and "Page with redirect" counts climbing as expected.
- Crawl the live site again to catch broken links and missed redirects.
- Use URL Inspection to request indexing for your most important pages.
- Check that enquiries and sales are still coming through the forms.
Weeks two to eight
- Compare clicks and impressions with your benchmark, page by page.
- Watch rankings for your top keywords. Small swings are normal while Google recrawls.
- Look for pages losing traffic and check whether their redirects, content or titles changed.
- Review the Core Web Vitals report once enough field data has built up.
Keep the old crawl export and URL map on file. If traffic to a page drops months later, they show you exactly what used to be there.
Common redesign mistakes we get called in to fix
When an Auckland business owner tells us their enquiries dropped after a new website went live, the cause is usually one of a handful of mistakes.
Redirecting everything to the homepage
It is quick, but Google often treats a mass redirect to the homepage like a missing page, because the homepage does not match what the old URL was about. Each old page needs a relevant destination. If a service no longer exists, redirect to the closest related service or category page.
Cutting the content that ranked
Designers like clean, minimal pages. Google likes pages that fully answer a query. A service page that drops from 800 words to 80 will usually drop in rankings too. Keep the substance and use design to make it easier to read, with headings, short paragraphs and clear calls to action.
Changing every title at once
Titles are one of the strongest on-page signals. Rewriting all of them on launch day, alongside new URLs and new content, makes it impossible to know what caused any drop. Carry over titles that perform well, and test changes to weaker ones after the migration settles.
Forgetting the small stuff
PDFs, image URLs, old blog posts, tracking parameters on ad landing pages and the www or non-www version of the domain all need handling. So do forms that send to an old email address and phone numbers that changed in the rebuild. These rarely make the project plan, which is why a written checklist matters.
Website migration SEO: platform and domain changes
Moving from Wix to WordPress, or WordPress to Shopify, adds platform-specific URL patterns. Shopify, for example, forces products into /products/ and pages into /pages/, so nearly every URL changes and the redirect map becomes critical. Our comparison of WordPress vs Shopify vs Webflow covers these structural differences.
Domain changes are the highest-risk migration. Keep the old domain registered and redirecting for as long as possible, ideally permanently. Update backlinks you control, such as directory listings, social profiles and industry associations.
What a good redesign can achieve
A redesign done properly is an opportunity, not just a risk to manage. When we rebuilt the website for Auckland plasterer Above Board Interiors and took over their SEO, organic traffic went from 66 to 378 visits a month over twelve months. The rebuild combined technical SEO, local keyword targeting, internal linking and content clustering around their core services. Read the full Above Board Interiors case study.
That kind of result starts with a migration that keeps what works, then builds on it with better structure and content. Ongoing local SEO in Auckland then compounds the gains.

Frequently asked questions
Will a website redesign hurt my SEO?
It can, if old URLs disappear without redirects, content is cut, or titles and internal links change carelessly. Done properly, with a full URL map, 301 redirects, preserved content and post-launch monitoring, a redesign usually holds rankings and often improves them, because the new site is faster and better structured.
How long does it take for rankings to recover after a website migration?
With a clean migration, many sites see little or no drop, and small fluctuations typically settle within a few weeks as Google recrawls the redirected URLs. Large sites or domain changes can take longer. If traffic is still well down after a month or two, check redirects, indexing and lost content in Google Search Console.
Should I use 301 or 302 redirects when redesigning a website?
Use 301 redirects for permanent URL changes, which is almost always the case in a redesign. A 301 tells Google the page has moved for good and that the new URL should replace the old one in search results. Use 302 only for genuinely temporary moves, such as a short-term promotion page.
Do I need to keep my old URLs when redesigning?
Keeping URLs that already rank well is the safest option and avoids redirects entirely. If the old URLs are messy or the site structure is changing, it is fine to change them, as long as every old URL that has traffic, links or rankings redirects to the most relevant new page.
How long should I keep redirects in place after a migration?
Keep them for at least a year, and ideally permanently. Google's own guidance suggests keeping redirects for as long as possible, generally at least a year. Old URLs can live on in backlinks, bookmarks and printed material for many years, so removing redirects later usually brings no benefit.
