Website Redesign SEO Checklist: 30 Steps to Protect Your Rankings Through a Relaunch

This checklist is for owners and founders relaunching a site with a freelancer, an agency or a new builder. It is not a full website redesign checklist for design and project management; it covers the SEO work that decides whether rankings and leads survive. If you are wondering how to redesign a website without losing SEO, the answer is mostly process. The rules below cite Google's own documentation, checked in September 2026.

Does a Website Redesign Affect SEO?

It can, when the redesign changes or removes something Google already relies on. Google's guide to site moves with URL changes (updated August 20, 2026) says any significant change may bring ranking fluctuations while Google recrawls and reindexes the site. When URLs change, it recommends permanent redirects and says medium-sized sites can take "a few weeks or more" to show the new URLs, and large sites longer.

Google also advises changing one thing at a time, so run a domain change and a redesign as separate projects where you can. The table shows which steps matter most for each type of project.

The Website Redesign SEO Checklist at a Glance (30 Steps)

Steps 1-8 happen before design, 9-16 during the build, 17-23 on launch day and 24-30 over the next 90 days. "You" means the owner or whoever runs the site.

Before Design Starts: Benchmark and Inventory Your Current Site (Steps 1-8)

These exports take an afternoon with free tools and become your baseline. To audit the old site first, use our technical SEO audit checklist.

• 1. Export Search Console data. Save clicks, impressions and position by page and query for the last 16 months, the range Google's traffic-drop guide uses to rule out seasonal dips.
• 2. Export GA4 landing pages and key events. Note which organic landing pages produce key events, GA4's name for important actions such as form submissions and calls.
• 3. Crawl and save every URL. Include status codes, sitemap URLs and your CMS page list. Screaming Frog SEO Spider is free for up to 500 URLs.
• 4. Save titles, meta, H1s, alt text and schema. Export them with the crawl. This is your reference for the new site.
• 5. List pages with external links. The Search Console Links report shows top linked pages. It is a sample, but every page on it needs a redirect row.
• 6. Flag keeper pages. Any URL with clicks, leads or external links. These are priority A in your redirect map.
• 7. Decide keep, improve, merge or remove. Merge thin near-duplicates into the strongest page, update dated pages that still have links, and remove only pages with no traffic, links or purpose.
• 8. Document your tracking. List GA4 events, tag manager tags, form destinations and call tracking numbers so each is rebuilt and tested at launch.

Questions to ask your web designer before you sign

• Will any URLs change, and why?
• Who builds, installs and tests the redirect map?
• Will titles, meta descriptions, headings and structured data carry over?
• How is staging kept out of Google, and who unblocks it at launch?
• Who tests analytics, forms and call tracking on launch day?
• What support is included if traffic or leads drop in month one?

Get the answers in writing. If nobody owns redirects and launch testing, those jobs fall to you.

How to Build a Redirect Map for a Website Redesign (Template)

A redirect map is a spreadsheet with one row per old URL. Priority A means clicks, leads or external links; B means some traffic; C means none. Build and test the A rows first.

To start your own, paste this header row into a spreadsheet and fill it from your step 3 URL list:

old_url,action,new_url,status_code,priority,notes

Redirect rules from Google

• Use server-side permanent redirects. Google's redirects guide recommends them whenever possible, and the site-move guide names 301 and 308. Use JavaScript redirects only as a last resort.
• Send each URL to its closest match. The site-move guide warns that sending many old URLs to one irrelevant page, such as the homepage, may be treated as a soft 404.
• Avoid chains. Googlebot follows up to 10 hops, but Google advises going straight to the final URL, or ideally no more than 3 hops.
• Let dead pages go. With no equivalent, return a 404 or 410. Google's status code guide treats both the same and drops the URL from its index.

How common builders handle redirects

Wix uses a URL Redirect Manager and adds a 301 automatically when you change most page URLs, but not for Wix Blog posts. Squarespace URL mappings use lines like /old-url -> /new-url 301, and Shopify URL redirects sit under Content > Menus; both only redirect from URLs that no longer exist, so delete or disable the old page first. WordPress sites usually use a redirect plugin or server rules. For sitemap and robots.txt settings by platform, see the platform notes in our technical SEO audit guide.

During Design and Build: Protect What Already Ranks (Steps 9-16)

The design can change completely while what Google ranks stays put: the address, the words, the titles and the links.

• 9. Keep existing URLs wherever possible. A new design doesn't need new addresses. Change a URL only for a clear gain, such as replacing /page.php?id=7.
• 10. Build the redirect map. Every old URL gets a row; use the template above.
• 11. Carry over ranking content. Don't cut copy that ranks to make a layout look cleaner. Improve it instead.
• 12. Carry over titles and meta descriptions. Copy titles, meta descriptions, H1s and alt text from step 4, and rewrite a title only when data supports it.
• 13. Keep internal links to key pages. Keep every keeper page in the menu, footer or a hub page. To plan the structure, see what pages a small business website should have.
• 14. Keep structured data and business details. Keep LocalBusiness structured data and a name, address and phone identical to your Google Business Profile. Several locations? See local SEO for multiple locations.
• 15. Keep staging out of Google. Google's robots.txt guide says robots.txt is not a way to keep pages out of Google. Use a password or noindex, and note that noindex only works if robots.txt doesn't block the page.
• 16. Test mobile and Core Web Vitals. web.dev rates LCP of 2.5 seconds or less, INP of 200 milliseconds or less and CLS of 0.1 or less as good, at the 75th percentile of real visits. Staging only gives lab results, so run Lighthouse in Chrome DevTools there and recheck in PageSpeed Insights after launch.

Launch Day SEO Checklist (Steps 17-23)

Run these in order, early in the week, while your developer is available.

• 17. Remove every staging block. Remove the noindex, any site-wide robots.txt Disallow rule and the password. On WordPress, untick "Discourage search engines from indexing this site"; the WordPress docs say it adds a noindex robots tag.
• 18. Deploy and test every redirect. Each old URL should 301 or 308 to a working page in one hop. Crawl your step 3 list to test every row.
• 19. Add self-referencing canonicals. Google's site-move guide says each new URL should canonicalize to itself. None should point to staging.
• 20. Point internal links at final URLs. Menus, footers and buttons should skip redirects.
• 21. Submit the new XML sitemap. Submit it in Search Console; the site-move guide says you can then drop the old sitemap. If you keep an old-URL sitemap for tracking, its indexed count should fall toward zero as the new one rises.
• 22. Check robots.txt, HTTPS and hostname. Block nothing important, serve every page over HTTPS and redirect http and www variants to one version. Change of Address is only for a domain or subdomain change.
• 23. Test analytics, forms and click-to-call. Submit every form, tap every phone link and confirm key events still record in GA4. Keep a backup of the old site.

After Launch: A 90-Day SEO Monitoring Plan (Steps 24-30)

• 24. Inspect top pages and re-crawl. Within 72 hours, live-test your top pages in the URL Inspection tool (indexing requests have a daily limit) and re-crawl for 404s, chains and stray noindex tags.
• 25. Check Page indexing weekly. In the Page indexing report, old URLs listed as "Page with redirect" are expected; new pages listed as "Not found (404)" or excluded by noindex are not. Google says sites under 1,000 pages shouldn't need the Crawl stats report.
• 26. Update off-site links. Update your Google Business Profile website link, social profiles, directories and ad destinations; the site-move guide lists profile links and ad campaigns. Moving campaign pages? Read our landing page vs website guide first.
• 27. Ask linking sites to update links. Start with the pages from step 5. Our white hat link building guide covers clean outreach.
• 28. Compare with your baseline at 7, 30, 60 and 90 days. Compare equal periods before and after launch in the Performance report, page by page. Site totals can hide losses on your best pages.
• 29. Keep redirects at least a year. The site-move guide says to keep them as long as possible, generally at least one year.
• 30. Fix drops with the triage table. Work through the table below from the top.

Google gives a timeline, not a percentage. Shopify's redesign SEO guide (March 2026) calls a first-month traffic change of roughly 0% to 20% common, but that is Shopify's own estimate; judge priority pages against your baseline.

Traffic Dropped After a Website Redesign? Diagnose It in This Order

Start at the top: the first rows cause the biggest, fastest drops.

Not every drop is the redesign. Google's traffic-drop guide also lists algorithm updates, security issues, spam problems and shifts in search interest, so compare the same dates year over year before you undo design work.

Changing Platforms, Themes or Domains: Extra Steps

• New theme, same platform. URLs usually stay, so check what the theme outputs: titles, headings, structured data, speed and the sitemap.
• New builder or CMS. URLs often change, so every page needs a redirect row and tracking must be rebuilt. Here the 30 steps double as a lightweight website migration SEO checklist; large or ecommerce migrations need a deeper plan.
• New domain. Redirect every URL one to one, then use the Change of Address tool. Search Console Help says to keep redirects at least 180 days, keep paying for the old domain for at least a year, and not to use the tool for http to https, www changes or moves within one domain.
• New host only. Google's guide to moves without URL changes says a temporary drop in crawl rate after launch is normal, followed by a steady increase over the next few days.

Common Website Redesign SEO Mistakes

• Redirecting every old URL to the homepage (step 18).
• Deleting old-looking pages that still earn links or leads (step 7).
• Launching with the staging noindex still on (step 17).
• Changing URLs with no clear reason (step 9).
• Rewriting titles site-wide without data (step 12).
• Heavy sliders or autoplay video that slow mobile pages (step 16).
• Forgetting the Google Business Profile link and call tracking (steps 23 and 26).
• Judging the relaunch in week one (step 28).

The Bottom Line on Your Website Redesign SEO Checklist

A website redesign SEO checklist comes down to five moves: benchmark, map, protect, test and monitor. Keep URLs when you can, and 301 them one to one to the closest new page when you can't. Next step: paste the redirect map header into a spreadsheet and fill it before design starts, then check key pages with the free single-page SEO check after launch.
