A website redesign is one of the biggest decisions you'll make for your online presence. But rushing through it—or skipping key steps—can cost you months of SEO ranking losses, missed revenue from broken redirects, and frustrated customers who can't find your content.

This checklist will guide you through every phase of a redesign, from the initial audit through launch and beyond. We've based it on years of helping Irish businesses redesign their websites without losing their search engine rankings or customer trust. Whether you're working with a web design agency or handling the redesign in-house, follow this step-by-step process to protect your SEO, plan your content changes, and launch with confidence.

Before You Start: The Pre-Redesign Audit

Benchmark your current performance

Before you touch your site, document everything about its current performance. This is your baseline—the numbers you'll use to measure whether the redesign actually helped. Record your organic traffic, keyword rankings, conversion rates, page load speeds, and bounce rates.

Audit your existing content

Go through every page on your current site. Document the title, meta description, word count, current rankings, and traffic. You'll use this during the redesign to decide which content to keep, which to update, and which to remove or redirect.

Identify what's working

Look at your analytics and ask: Which pages get the most visitors? Which pages generate the most enquiries or sales (a content audit makes this systematic)? Which pages have the lowest bounce rates? These high-performing pages are sacred—protect them during your redesign, update them thoughtfully, and never delete them without setting up a redirect.

Document your current URL structure

Export a full list of your current URLs and their rankings, traffic, and any inbound links. You'll use this to create a URL redirect map for your new site. URLs that rank well in Google are sending you free traffic—break them in your redesign and you'll lose that traffic.

During Planning: Strategic Decisions

Define clear goals

Don't redesign just to redesign. Clarify what you're actually trying to achieve. More traffic? Better conversions? A faster site? An easier CMS to manage? Your goals will shape every decision you make about design and functionality.

• Increase organic traffic by X% in 6 months
• Improve page load speed below 2 seconds (mobile)
• Reduce bounce rate on key landing pages
• Increase form submissions or sales by X%
• Migrate to a more modern, scalable platform
• Improve internal linking and site structure for better crawlability

Write these goals down. Share them with your design agency or internal team. Measure your progress against these goals in the 90 days after launch.

Plan your URL structure

Decide now: Will you keep the same URL structure? Change some URLs? Restructure everything? If you're changing URLs, you must set up 301 redirects from the old URLs to the new ones. This tells Google that your content moved, not disappeared.

Ask your design agency to provide a complete URL mapping document before handover. It should show: old URL → new URL, with a note for any pages that are being consolidated or removed. Then test every redirect before you go live.

Decide on platform and hosting

Is your redesign also a platform migration (moving from Wix to WordPress, or vice versa)? This adds complexity and risk. If you're changing platforms, your redirect strategy becomes even more critical. Make sure your new platform can handle your current traffic and has good SEO capabilities.

The Design Phase Checklist

• Decide on layout, color scheme, and typography
• Design for mobile first, then scale up to desktop
• Plan your navigation structure—make it clear and logical
• Create a mobile menu that's easy to use on small screens
• Design all key pages (homepage, service pages, about, contact, blog)
• Plan your forms (contact, quote requests, signups)
• Decide on CTA button placement and messaging
• Create wireframes for desktop, tablet, and mobile
• Get stakeholder sign-off before moving to development

The Development Phase Checklist

• Set up a staging environment (exact copy of live site before launch)
• Implement SEO basics (title tags, meta descriptions, H1s, schema markup)
• Set up internal linking strategy (links between related content)
• Create XML sitemap and robots.txt
• Ensure all images are optimized (compressed and properly formatted)
• Implement page speed optimizations (minify CSS/JS, lazy load images)
• Set up analytics tracking (Google Analytics, tracking pixels)
• Test forms for functionality and deliverability
• Implement HTTPS/SSL certificate
• Set up custom 404 page for missing pages
• Configure favicon and meta tags for browser tabs

The Pre-Launch Checklist

• Test all pages on multiple browsers (Chrome, Firefox, Safari, Edge)
• Test on multiple devices (iPhone, Android, iPad, desktop)
• Test all forms—make sure submissions are received and data is correct
• Test all internal links (use a crawl tool to find broken links)
• Test all external links—are they still working?
• Test page load speed on mobile and desktop (use PageSpeed Insights)
• Test SEO setup (title tags, meta descriptions, H1s, structured data)
• Set up 301 redirects from old URLs to new URLs
• Double-check that analytics and tracking are firing correctly
• Take a final backup of your old website (just in case)
• Inform customers of the launch date (email, social media, site banner)

Launch Day Checklist

• Update DNS records to point to your new hosting (if applicable)
• Switch the domain over to the new site
• Test the live site immediately after switching (all pages, forms, links)
• Monitor error logs and uptime for the first 24 hours
• Update internal links in your CMS to point to new URLs
• Submit new XML sitemap to Google Search Console
• Verify in Search Console that redirects are working
• Monitor traffic and rankings for anomalies
• Be ready to roll back if critical issues emerge

Post-Launch: The First 30 Days

Your work doesn't end when you flip the switch. The first 30 days are critical for protecting your SEO investment and catching any issues before they impact your traffic. Here's what to focus on in your first month.

• Week 1: Monitor traffic daily. Look for drops in traffic or rankings. Check your error logs and fix any critical issues immediately.
• Week 1-2: Monitor your redirects. Use Google Search Console to check that old URLs are redirecting correctly. Look for redirect chains or redirect errors.
• Week 2: Check all your conversions (forms, sales, signups). Make sure everything is still working. If conversion rates dropped, investigate why.
• Week 2-3: Monitor page speed and Core Web Vitals. Use Google PageSpeed Insights and Search Console to see if your speed improved or declined.
• Week 3: Analyze which pages have traffic drops. If specific pages lost traffic, check: are they ranking for the same keywords? Did the redirect work? Is the new page structure different?
• Week 4: Publish fresh content or update existing content on your best-performing pages. This signals to Google that your site is alive and active.

Don't panic if your rankings fluctuate in the first few weeks. Google's algorithm needs time to re-evaluate your new site structure. Most sites see their rankings stabilize within 2-4 weeks if they've followed SEO best practices during the redesign.

Common Redesign Mistakes to Avoid

• Not setting up 301 redirects—broken links kill your SEO
• Removing content without redirects—you lose all the ranking power that page built up
• Changing your URL structure without planning—old URLs stop working
• Ignoring internal links—they distribute ranking power through your site
• Removing schema markup (JSON-LD)—this helps Google understand your content
• Redesigning without a baseline—you won't know if the redesign actually helped
• Launching without monitoring—issues compound quickly in the first hours after launch
• Not testing on mobile—Google uses mobile-first indexing now
• Forgetting to update sitemaps and robots.txt—Google can't find all your new pages
• Not planning for ongoing content updates—a redesign is not a 'set and forget' project

Frequently Asked Questions

How long does a website redesign take?

A typical website redesign takes 8-16 weeks, depending on your site's size, complexity, and whether you're migrating platforms. A simple brochure site might take 4-6 weeks. A large ecommerce site or complex custom build might take 4-6 months. Budget time for your approval stages, content updates, and testing—these often extend the timeline.

Will my traffic drop during a redesign?

Short answer: it shouldn't if you follow this checklist. Most traffic drops during redesigns happen because of broken redirects, poorly set up SEO basics, or lost internal links. If you keep your URL structure, set up proper redirects, maintain your SEO signals, and monitor your site after launch, your traffic should stay flat or grow. Some sites see a brief (2-4 week) dip due to Google re-evaluating the new site, but this recovers.

Should I redesign and rebrand at the same time?

Technically yes, but it's risky. A redesign alone is complex. Adding a rebrand (logo, color scheme, messaging) makes it harder to pinpoint what caused any traffic changes. If your brand refresh is essential, go ahead—but go slowly, communicate the rebrand to your audience in advance, and be prepared to monitor carefully for any ranking impacts.

What's the best CMS platform for a redesigned website?

The best CMS is the one your team can actually use. WordPress powers 43% of the web and has excellent SEO support. Webflow is great if you want design control without code. Shopify is best for ecommerce. Ghost is ideal for blogs and content sites. Ask your design agency what platform they recommend for your specific goals and who will be managing it long-term.

How do I track whether the redesign actually helped?

This is why that baseline benchmark is so important. Set up your analytics and Search Console before the redesign launches. Then, 90 days after launch, compare: organic traffic, keyword rankings, conversion rates, page load speed, and bounce rates. Measure your progress against the goals you set in the planning phase. A successful redesign should improve most (if not all) of these metrics.

Should I consider Irish language or bilingual requirements during a redesign?

If your business serves Irish-speaking communities or works with public sector clients, a redesign is the ideal time to plan bilingual content. Building Irish language support into the redesign from the start is much cheaper than retrofitting later. See our guide to Irish language and bilingual websites for what to consider.
