Website Redesign Checklist (SEO-safe)

A website redesign isn’t just a design project—it’s a migration. You’re changing URLs, templates, tracking, and sometimes your entire content structure. Done right, it improves performance and conversions. Done poorly, it can wipe out SEO and break your funnel overnight.

This checklist is built for marketing managers who need to run the process—not just participate in it. It focuses on what actually breaks during redesigns and how to prevent it.

If you do nothing else, do these five things:

• Build a complete URL inventory (what exists today)
• Create a redirect map (old to new URLs)
• Validate tracking before and after launch
• Run a structured launch checklist (not vibes)
• Monitor daily for 2–4 weeks post-launch

Most redesign failures come down to skipping one of these.

Before design even starts, you need a clear picture of what you’re protecting.

What to do:

• Export all URLs (from WordPress + analytics)
• Identify top-performing pages (traffic + conversions)
• Capture baseline metrics:
  • Organic traffic
  • Conversion rate
  • Top landing pages
• Define success criteria:
  • “No loss in organic traffic”
  • “+X% conversion rate”
  • “Improved page speed”

If you skip this, you won’t know if the redesign worked—or what broke.

This is where most redesigns fail.

Your non-negotiables:

• Every old URL must map to a new one (no exceptions)
• Use 301 redirects (not temporary)
• Avoid redirect chains (old → new → newer)
• Don’t send everything to the homepage
• Install a redirection plugin on your WordPress website

Also check:

• No accidental noindex on production
• Robots.txt isn’t blocking your site
• Internal links point to new URLs
• Sitemap is updated and submitted

Think of this as plumbing. If it’s wrong, nothing else matters.

Design isn’t just visual—it affects SEO, accessibility, and performance.

Make these explicit in handoff:

• Pages must use real HTML text (not images)
• Navigation links must be crawlable (<a href>)
• Mobile and desktop content must match
• WordPress’s setup must support:
  • Meta titles/descriptions
  • Alt text
  • Structured content fields

Bonus (but important):

• Accessibility basics (contrast, focus states)
• Performance targets (Core Web Vitals)

If it’s not written in the handoff, it won’t get built.

A redesign often “breaks data” even if everything else works.

Before launch:

• Define your key events (form submits, purchases, etc.)
• Test in staging (using GA4 DebugView or equivalent)
• Make sure Site Kit is installed on your WordPress installation

After launch:

• Check:
  • Page views firing correctly
  • Conversions tracking once (not double)
  • Forms actually reaching your CRM

If tracking is broken, you’ll think the redesign failed—even if it didn’t.

Do not “just push live.”

Your runbook should include:

• Backup completed
• Redirects active
• Noindex removed
• Sitemap submitted
• Tracking validated

Then:

• Test top 20–50 URLs manually
• Verify key conversion flows
• Decide: go / no-go

Launch is a controlled release, not a moment.

Expect some fluctuation. But you need to watch closely.

Daily (week 1):

• 404 errors
• Redirect issues
• Traffic drops
• Conversion changes

Weekly (weeks 2–4):

• Rankings and organic traffic
• Page performance (speed)
• Conversion trends

Most issues show up in the first 7 days. The rest show up slowly.
