WordPress Redesign and Migration Checklist for Teams That Cannot Afford to Lose Traffic

Most redesign disasters aren’t design problems. They’re checklist problems. The new site looks great, launch day goes well, and three weeks later organic traffic is down a third and nobody knows why. Almost every time, something on the technical list got skipped because it wasn’t glamorous.

This is the checklist we work through at GG Studio when we redesign or migrate a site. It’s boring on purpose. Boring is what protects your traffic. Go through it in order and a redesign should cost you nothing in rankings, and usually improve them.

One thing up front: the most common cause of post-launch traffic loss is redirect gaps. Half of this list exists to make sure that doesn’t happen to you.

Phase 1: Before You Touch Anything (The Audit)

This phase is the insurance policy. Skip it and you’re flying blind.

• Crawl the whole current site with Screaming Frog or Ahrefs Site Audit. Export every URL: pages, posts, category and tag archives, PDFs, everything.

• Export top pages by organic traffic from Google Search Console (last 12 months). This is your protection list, the pages you can’t disturb.

• Export top keywords and rankings. Know what you rank for and where, so you can spot movement after launch.

• Pull your backlink profile. Find which URLs have external links. Those pages carry authority you must keep at the same URL or redirect cleanly.

• Document on-page SEO for every important page: title, meta description, H1 and any structured data. You’ll reproduce these.

• Record a traffic and rankings baseline the week before launch. If something moves, you need to know what “before” looked like.

• List every form, integration and tracking tag: analytics, pixels, CRM, marketing automation. These break silently if nobody lists them.

Phase 2: Planning the New Site

• Decide the URL structure. Will URLs stay or change? Every change is a redirect you’ll have to build. Keep URLs identical wherever you reasonably can. It’s the lowest-risk path.

• Map old content to new. Which pages survive, which merge, which go. A redesign is the best content cleanup you’ll ever get. Use it to remove thin pages that bring nothing.

• Plan the CMS structure: content types, collections, fields. Create SEO title and description fields now, before importing anything.

• Define the design system first: type, color, spacing, components. Build pages from the system, not one by one. It’s what keeps the site consistent and editable afterward. When we built KTA+’s 20+ pages, everything came from one design system, which is why their team can keep adding pages that look right.

• Pick the platform. If you’re still deciding, read WordPress to Webflow or Framer: which path is right for you.

Phase 3: Building the Redirect Map (Non-Negotiable)

This one document protects your traffic more than anything else on the list.

• List every old URL from the crawl.

• Give each a destination: same URL (no redirect), new URL (301 to the new address) or retired (301 to the closest relevant page that survives).

• Never send dead pages to the homepage in bulk. Google treats it as a soft 404 and passes almost no authority. Redirect to the nearest relevant page.

• Check for redirect chains (old to middle to final) and collapse them into one hop.

• Build it as a spreadsheet with three columns: old URL, new URL, redirect type. Review it line by line.

Phase 4: Reproducing SEO on the New Site

• Carry over every title and meta description from the audit.

• Keep the heading structure: one H1 per page, logical H2 and H3 below it.

• Add back image alt text. It doesn’t migrate itself.

• Rebuild structured data on the pages that had it.

• Rebuild internal links. WordPress sites pile them up over years and a clean rebuild often loses them. They affect rankings, so restore them.

Phase 5: Technical Pre-Launch

• Generate a new XML sitemap.

• Set canonical tags correctly on every page.

• Check robots.txt so you’re not blocking the new site or leaving it noindexed.

• Verify the new site in Search Console before launch where possible.

• Test page speed and Core Web Vitals on staging, on real pages, on mobile.

• Re-install all tracking: analytics, pixels, CRM. Test that the events actually fire.

• Test every form end to end. A broken contact form on a B2B site is lost revenue, not just bad UX.

Phase 6: QA on Staging

• Click every internal link. Every one.

• Test every redirect in the map. The old URL should land on the right new page.

• Check mobile, tablet and desktop.

• Proofread. Migrations introduce copy errors more often than you’d think.

• Test in several browsers.

Phase 7: Launch

• Launch early in the week, not before a weekend, so you’re around to catch problems.

• Turn on all 301 redirects at go-live.

• Submit the new sitemap in Search Console right away.

• Request indexing of your most important pages.

Phase 8: The First Month (Where Migrations Are Won or Lost)

Launch isn’t the end. This phase saves or sinks the redesign.

• Compare organic traffic to the baseline every day.

• Watch Search Console’s indexing reports for crawl errors and unexpected 404s.

• Re-crawl the live site after a few days to catch missed redirects and broken links.

• Track rankings for your priority terms.

• Expect a small dip in week one while Google re-crawls and re-indexes. That’s normal. A dip that doesn’t recover within a few weeks means something is broken, usually a redirect gap. Find it fast.

The Honest Truth About Checklists

None of this is clever. It’s discipline. The teams that lose traffic in a redesign aren’t the ones without talent. They’re the ones who treated SEO as a launch-day task instead of a pre-launch discipline. By launch day, every protection on this list should already be built and tested.

For the platform versions of this process, see the WordPress to Webflow migration guide and the WordPress to Framer migration guide. For a deeper look at protecting rankings, how to migrate from WordPress without losing SEO goes further on the search side.
