Website Redesign Checklist: How to Redesign Without Losing Rankings

October 15, 2026 8 min readBy the KMI team

A website redesign should bring in more leads. Too often it does the opposite: traffic drops after launch because pages disappear, URLs change and months of SEO work is lost. This checklist helps you redesign without losing rankings.

Before you start

  • Set clear goals. More leads? Better mobile experience? Easier updates? Write them down with numbers where possible.
  • Benchmark today's performance. Record traffic, top pages, conversions and rankings for your key searches.
  • Crawl the current site. Use a crawler or your CMS export to list every URL, including blog posts, images and PDFs.
  • Export Search Console data. Note the pages and searches that bring the most clicks.
  • List your backlinks. Pages other sites link to must keep working.

Content planning

  • Decide for every page: keep, improve, merge or retire
  • Keep high-traffic and high-converting pages, even if you rewrite them
  • Merge thin or duplicate pages into stronger ones
  • Plan any new pages you need, such as services or locations
  • Preserve or improve title tags and meta descriptions for important pages

Redirect plan

  • Map every old URL to the most relevant new URL
  • Use 301 (permanent) redirects, not 302s
  • Avoid redirect chains (A → B → C); point old URLs straight to their final destination
  • Never redirect everything to the homepage
  • Automate the redirect list so it's easy to test and update

Design and build

  • Design mobile-first
  • Keep navigation simple and clear
  • Put a strong call to action on every key page
  • Set a performance budget and test page speed as you build
  • Use descriptive alt text and accessible color contrast
  • Add structured data (Organization, LocalBusiness, Service, FAQ)

Pre-launch testing

  • Build and review on a staging site that search engines can't index
  • Test every redirect from your list
  • Check for broken links and missing images
  • Test every form and confirm leads arrive
  • Confirm analytics and conversion tracking work
  • Check the site on several phones and browsers
  • Make sure the staging "noindex" setting will be removed at launch

Launch day

  • Remove any noindex tags and check robots.txt
  • Submit the new XML sitemap in Google Search Console and Bing Webmaster Tools
  • Spot-check old URLs to confirm they redirect correctly
  • Watch your form inboxes to confirm leads are coming through

After launch

  • Monitor Search Console for 404 errors daily for the first two weeks, then weekly
  • Add redirects for any missed URLs
  • Compare traffic, rankings and conversions with your benchmark
  • Expect small ranking fluctuations for a few weeks; investigate anything that doesn't recover

The bottom line

A careful redesign protects what's already working while improving everything else. Most lost rankings come from skipping the content inventory and redirect steps.
