This website redesign checklist covers the 12 things worth verifying before you flip the switch on a new site. Skip any one of them and you risk losing search rankings, breaking forms, or sending customers to a 404 page on launch day. None of it is complicated, but all of it is easy to forget in the rush to finally go live.

Website Redesign Checklist: SEO and Redirects

Map every old URL to its new equivalent with 301 redirects. According to Google Search Central’s own guidance on redirects, a permanent 301 redirect is the clearest signal you can send that a page has moved, and it is the single most important item on this website redesign checklist for protecting existing rankings.
Preserve your top-performing page titles and meta descriptions. A redesign is not the time to rewrite SEO copy that is already working, unless you have a specific reason to.
Update and resubmit your XML sitemap in Google Search Console so the new URL structure gets crawled quickly.
Reconnect Google Analytics and Search Console to the new site, and confirm tracking is firing correctly before launch, not after.

Website Redesign Checklist: Technical and Performance

Test mobile responsiveness on real devices, not just a browser’s resize tool. Layout issues often only show up on an actual phone.
Check page speed and Core Web Vitals before launch. A beautiful redesign that loads slowly will lose both rankings and visitors.
Confirm your SSL certificate is active and every page loads securely with no mixed-content warnings.
Crawl the site for broken links and images that did not carry over correctly from the old build.

Website Redesign Checklist: Content and User Experience

Test every form, including contact forms, quote requests, and newsletter signups, to confirm submissions actually arrive.
Customize your 404 page so any missed redirects still guide visitors back to useful content instead of a dead end.
Preserve or rebuild schema markup for reviews, local business information, and FAQ that were present on the old site.
Take a full backup immediately before cutover, and launch during a low-traffic window in case anything needs a quick rollback.

Key Takeaways

301 redirects mapped from every old URL are the single highest-priority item on any website redesign checklist.
Technical checks, like page speed, mobile responsiveness, and SSL, protect both rankings and user experience.
Forms, schema markup, and a custom 404 page are easy to overlook but directly affect leads and lingering SEO value.
A full backup and a low-traffic launch window give you room to fix anything that slips through.

Frequently Asked Questions

What is the most important item on a website redesign checklist?

Mapping 301 redirects from every old URL to its new equivalent is the highest priority. Without it, a redesign can wipe out years of accumulated search rankings almost overnight.

How long before launch should I start this checklist?

Start technical checks, like redirects and schema markup, at least two weeks before launch. Final checks, like forms and mobile testing, should happen on staging in the final 48 hours.

Will a website redesign hurt my SEO rankings?

It can, but usually only when redirects are missed, titles and meta descriptions are rewritten unnecessarily, or the sitemap is not resubmitted. Following a full website redesign checklist largely prevents this.

Do I need a developer to complete this checklist?

Some items, like redirects and schema markup, are easier with technical help, but most of this checklist, like testing forms and checking mobile layouts, can be done by anyone on staging before launch.
