Website Redesign Checklist: 25 Steps to Follow Before You Launch

Why You Need a Website Redesign Checklist

A website redesign is one of the most exciting projects a team can tackle. It is also one of the riskiest. Forgotten redirects, broken links, missing metadata, lost SEO rankings, and analytics gaps can undo months of hard work in a single afternoon.

We have seen teams lose 30% or more of their organic traffic overnight because they skipped a few seemingly small steps. That is revenue, leads, and trust disappearing in an instant.

This website redesign checklist exists to make sure that does not happen to you. We have organized 25 actionable steps across six phases so your team can work through them systematically before, during, and immediately after launch day.

Quick Overview: The 25-Step Website Redesign Checklist

Here is a summary table of every step. We go into full detail on each one below.

Phase 1: Pre-Redesign Audit

Before a single wireframe is drawn, you need to understand exactly what you have today and what success looks like tomorrow. Skipping this phase is the number one reason redesign projects go sideways.

1. Define Clear Redesign Goals and KPIs

Why are you redesigning? The answer needs to be more specific than “it looks outdated.” Common goals include:

• Increasing conversion rate by a specific percentage
• Reducing bounce rate on key landing pages
• Improving page load speed to meet Core Web Vitals thresholds
• Supporting a rebrand or new product line
• Improving accessibility compliance

Write these goals down and assign measurable KPIs. Every design decision and technical choice should map back to at least one of them.

2. Audit Current Site Performance and Analytics

Pull data from your analytics platform covering at least the last 12 months. Document:

• Top-performing pages by traffic, conversions, and engagement
• Bounce rates by page and device type
• Traffic sources (organic, paid, referral, direct)
• User flow and drop-off points

This data tells you what is working and what must be preserved. It also gives you a baseline to measure the redesign against.

3. Complete a Full Content Inventory

Create a spreadsheet listing every page, blog post, PDF, image, and downloadable asset on your current site. For each item, note:

• URL
• Page title and meta description
• Whether the content will be kept, updated, merged, or removed
• Who is responsible for the content decision

A content inventory prevents the all-too-common scenario where important pages simply vanish after launch.

4. Crawl and Document Every Existing URL

Use a crawling tool like Screaming Frog, Sitebulb, or Ahrefs Site Audit to generate a complete list of URLs. This list becomes the foundation for your redirect map in Phase 2.

Pay special attention to:

• Pages with high organic traffic
• Pages with significant backlinks
• Pages that rank on page one for important keywords

5. Benchmark Current SEO Rankings and Backlinks

Before you change anything, create a snapshot of your current SEO standing:

• Keyword rankings for your target terms
• Domain authority and page authority scores
• Top backlinks and the pages they point to
• Indexed page count in Google Search Console

You will use this data after launch to detect any ranking drops early enough to fix them.

Phase 2: SEO and Content Migration

This is where the most costly mistakes happen. A redesign that ignores SEO can tank your organic traffic for months. Every step here is essential.

6. Build a Comprehensive 301 Redirect Map

If any URL changes during the redesign, you need a 301 redirect from the old URL to the new one. This is non-negotiable.

Create a redirect map in a spreadsheet with two columns:

Tips for getting redirects right:

• Map every old URL, not just the top pages
• Avoid redirect chains (A redirects to B which redirects to C)
• Never redirect all old pages to the homepage. This is treated as a soft 404 by Google
• Test every redirect before launch

7. Migrate and Optimize All Metadata

For every page on the new site, make sure you have:

• A unique, keyword-optimized title tag (under 60 characters)
• A compelling meta description (under 155 characters)
• Proper Open Graph and Twitter Card tags for social sharing

Do not let metadata fall through the cracks. We have seen redesigned sites launch with placeholder text like “Page Title Here” in their title tags. Embarrassing and damaging.

8. Preserve or Improve On-Page SEO Elements

Check these elements on every important page:

• H1 tags (one per page, include primary keyword)
• Header hierarchy (H2, H3, H4 used logically)
• Image alt text for all images
• Internal links pointing to relevant pages
• Structured data / schema markup

A redesign is a great opportunity to improve your on-page SEO, not just maintain it.

9. Update XML Sitemap and robots.txt

Your new sitemap should reflect only the new URL structure. Double-check that:

• All new pages are included
• No old or removed URLs remain
• The sitemap validates without errors
• Your robots.txt file does not accidentally block important pages or the entire site (this happens more often than you would think, especially when staging site rules carry over to production)

10. Verify Canonical Tags and Hreflang

Canonical tags tell search engines which version of a page is the “main” one. After a redesign, outdated canonical tags can point to URLs that no longer exist.

• Audit every page to confirm the canonical tag points to the correct new URL
• If your site serves multiple languages or regions, verify all hreflang tags are updated

Phase 3: Design and UX Verification

A beautiful redesign means nothing if users cannot actually use the site. These five steps ensure your new design works for real people on real devices.

11. Cross-Browser and Cross-Device Testing

Test your redesigned site on, at minimum:

• Browsers: Chrome, Firefox, Safari, Edge
• Operating systems: Windows, macOS, iOS, Android
• Screen sizes: Desktop (1920px, 1440px, 1024px), tablet, and mobile

Use tools like BrowserStack or LambdaTest to cover combinations your team cannot test manually.

12. Mobile Responsiveness Check

Google uses mobile-first indexing. Your mobile experience is your primary experience in the eyes of search engines. Check for:

• Text readability without zooming
• Tap targets that are large enough (at least 48×48 pixels)
• No horizontal scrolling
• Images that scale properly
• Menus that work on touch devices

13. Accessibility Audit (WCAG Compliance)

Accessibility is not optional. It is a legal requirement in many jurisdictions and the right thing to do. Run your site through an accessibility checker and verify:

• Sufficient color contrast ratios
• Keyboard navigation works on all interactive elements
• Screen readers can interpret your content correctly
• All images have descriptive alt text
• Form fields have associated labels

14. Navigation and Internal Linking Review

Walk through your site as if you were a first-time visitor. Can you find key information within three clicks? Specifically check:

• Main navigation links all work and point to correct pages
• Footer links are updated
• Breadcrumbs display correctly
• Internal links within content point to valid URLs (not old ones)
• Search functionality returns accurate results

15. Visual Consistency and Branding Alignment

Review every page template for:

• Consistent use of brand colors, fonts, and spacing
• Properly sized and optimized images (no stretched or pixelated visuals)
• Consistent button styles and hover states
• Correct logo usage and placement

Phase 4: Technical QA

This phase catches the bugs and technical debt that can quietly undermine your entire redesign.

16. Page Speed and Core Web Vitals Optimization

Run every key page through Google PageSpeed Insights and aim for:

Common speed killers in redesigns include unoptimized hero images, excessive JavaScript bundles, render-blocking CSS, and too many third-party scripts loaded on page load.

17. SSL Certificate and HTTPS Enforcement

Confirm that:

• Your SSL certificate is valid and not expiring soon
• All pages load over HTTPS
• HTTP requests redirect to HTTPS
• No mixed content warnings appear (HTTP resources loaded on HTTPS pages)

18. Form, CTA, and Conversion Path Testing

Every form and call-to-action on your site is a potential revenue generator. Test each one thoroughly:

• Contact forms submit correctly and send notifications to the right email addresses
• Newsletter signup forms connect to your email marketing platform
• E-commerce checkout flows complete without errors
• Download links work and serve the correct files
• Thank you pages and confirmation messages display properly

Pro tip: Use a real email address (not a test alias) to verify that form submissions actually arrive in your inbox.

19. Third-Party Integrations and Scripts Check

Redesigns frequently break third-party integrations because code snippets get lost during the migration. Verify:

• CRM integrations (HubSpot, Salesforce, etc.)
• Live chat widgets
• Marketing automation triggers
• Payment gateways
• Social media embeds and share buttons
• Cookie consent banners and privacy compliance tools

20. Error Page and 404 Handling

Create a custom 404 page that is helpful, on-brand, and guides visitors back to useful content. Then test it by deliberately visiting a nonexistent URL.

Also set up monitoring so you are alerted to spikes in 404 errors after launch. A sudden increase usually means your redirect map has gaps.

Phase 5: Analytics and Tracking

If you cannot measure it, you cannot prove the redesign was worth it. These steps ensure your data pipeline is intact from day one.

21. Reinstall and Verify Analytics Tracking Codes

Check that your analytics platform (Google Analytics 4, Matomo, or whichever tool you use) is firing correctly on every page. Use the real-time reports to confirm data is coming through.

Common issues after a redesign:

• Tracking code missing from certain page templates
• Duplicate tracking codes causing inflated pageview counts
• Tag Manager container not published to the production environment

22. Set Up Goal and Event Tracking

Recreate or update your conversion goals and custom events to match the new site structure. This includes:

• Form submission events
• Button click tracking
• Scroll depth tracking
• Video play events
• File download tracking

If your URLs changed, any goals based on destination URLs will need updating.

23. Connect Google Search Console and Resubmit Sitemap

In Google Search Console:

1. Verify that your property is still connected and verified
2. Submit your updated XML sitemap
3. Use the URL Inspection tool to request indexing of your most important new pages
4. Monitor the Coverage report for any indexing errors in the days following launch

Phase 6: Launch Day and Post-Launch

You have done the preparation. Now it is time to go live and stay vigilant.

24. Update DNS, Go Live, and Run Immediate Smoke Tests

On launch day, follow this sequence:

1. Update DNS settings to point to the new site
2. Clear all caches (CDN, server-side, browser)
3. Verify the homepage loads correctly
4. Test five to ten critical pages across devices
5. Submit a purchase or form on each conversion path
6. Spot-check 20+ redirects from your redirect map
7. Run a quick crawl to scan for broken links or unexpected 404s
8. Confirm analytics and tracking are recording live data

Do not launch on a Friday afternoon. If something breaks, you want your full team available to fix it. Mid-week, early in the day is ideal.

25. Monitor Traffic, Rankings, and Errors for 30 Days

The first 30 days after launch are critical. Set up daily monitoring for:

• Organic traffic trends: Compare week over week with the same period before the redesign
• Keyword rankings: Watch for drops on your most valuable terms
• Crawl errors: Check Google Search Console daily for the first two weeks
• 404 spikes: Use server logs or a monitoring tool to catch missing redirects
• Conversion rates: Ensure your forms and CTAs are performing at or above the old baseline
• Page speed: Verify Core Web Vitals remain within acceptable ranges under real traffic

If you notice a significant drop in any metric, investigate immediately. The sooner you catch and fix issues, the less long-term damage they cause.

The 5 Most Costly Website Redesign Mistakes We See

After working on countless web projects, here are the mistakes that cause the most damage:

1. Launching without a redirect map. This single oversight can wipe out years of SEO work overnight. Every old URL needs a plan.
2. Forgetting to reinstall tracking codes. Teams celebrate the new design while flying blind because no analytics data is being collected.
3. Ignoring page speed. A gorgeous new design loaded with heavy images and animations can actually perform worse than the old site.
4. Not testing forms before launch. Leads and sales stop flowing in because a form was broken and nobody noticed for days.
5. Skipping the post-launch monitoring period. Problems always surface after launch. The teams that catch them in 24 hours fare far better than those who discover them weeks later.

Frequently Asked Questions

How long does a website redesign typically take?

Most website redesigns take between 8 and 16 weeks depending on the size and complexity of the site. Large enterprise sites with hundreds of pages and complex integrations can take 6 months or more. Using a structured website redesign checklist helps keep the project on schedule by reducing unexpected issues.

Will a website redesign hurt my SEO rankings?

It does not have to. If you follow proper SEO migration steps, especially building a thorough 301 redirect map, preserving metadata, and maintaining your content quality, you can maintain or even improve your rankings. The sites that lose rankings are almost always the ones that skipped the SEO migration steps.

Should I redesign my website all at once or in phases?

Both approaches can work. A phased redesign reduces risk because you are changing fewer things at once, making it easier to isolate problems. A full redesign gives you a clean slate and a more consistent result. The right choice depends on your resources, timeline, and risk tolerance.

How do I know if my website actually needs a redesign?

Common signals include declining conversion rates, poor mobile performance, outdated branding that no longer reflects your company, slow page load times, accessibility issues, or a content management system that your team struggles to use. Start by auditing your current site data before committing to a full redesign.

What is the most important step on this website redesign checklist?

If we had to pick one, it would be Step 6: building the 301 redirect map. Broken redirects are the single most common cause of traffic loss after a website redesign. Get this step right and you protect the organic search equity you have spent years building.

How soon after launch should I expect to see results?

You should see immediate feedback on technical performance metrics like page speed and Core Web Vitals. SEO rankings may fluctuate for two to four weeks as search engines recrawl and reindex your site. Conversion rate improvements often become clear within the first 30 to 60 days, assuming you are tracking them properly from day one.
