Website Migration Checklist: How to Move Without Losing Traffic
Migrate with Confidence, Not Chaos
Website migration can be one of the most transformational—but risky—events
in a brand’s digital lifecycle. Think of it like moving into a new home.
It’s a chance to upgrade, redesign, and reorganise—but without a clear
roadmap, it’s all too easy to lose valuable assets, leave boxes unpacked, or
forget where everything belongs.
Whether you're revamping your design, shifting to a new domain, migrating to
a different CMS, merging multiple websites, or simply moving from HTTP to
HTTPS, the risks are real. A poorly planned migration can lead to:
• Loss of organic traffic and hard-earned backlinks
• Disrupted user journeys
• Broken internal links or missing redirects
• Damaged brand credibility
And in many cases, these issues don’t show up immediately—they appear weeks
later, when recovery becomes much harder.
But here’s the good news: migration doesn’t have to mean chaos. In fact,
with the right approach, it's a prime opportunity to strengthen your site
architecture, improve SEO performance, increase load speed, streamline your
user experience, and set the stage for long-term digital growth.

• Unlock performance improvements post-launch
Because in today’s competitive digital landscape, a flawless migration isn’t optional—it’s essential.
Why Website Migration Requires Strategy
Website migrations are often misunderstood as cosmetic changes—just a new
design, a platform switch, or a domain update. But the truth is, they go
much deeper. A migration isn’t just about how your site looks. It’s about
how it works, how it’s found, and how it performs. Without a clear strategy,
what should be a step forward can easily turn into a setback.
Whether you're changing your CMS, rebranding with a new domain, or
rebuilding the entire site architecture, migrations affect multiple layers
of your online presence:
1. SEO Rankings and Organic Traffic
Your website’s current rankings are the result of years of accumulated SEO value—backlinks, content authority, domain trust, and crawl history. Even the slightest misstep, like broken redirects or lost meta data, can tank your visibility overnight. If Google can’t find or understand your new URLs, your rankings can drop significantly, and take months to recover.
2. Site Speed and Core Web Vitals
Migrating gives you the chance to improve loading times, responsiveness, and interactivity scores. But if not executed correctly, new themes, plugins, or scripts can slow your site down. Poor Core Web Vitals can hurt user experience and affect your position in Google’s algorithm, which now heavily weights performance metrics.
3. Crawlability and Indexing
When a migration isn’t mapped out properly, search engines may struggle to crawl and index your new site. This often happens when sitemaps aren’t updated, robots.txt files are misconfigured, or internal linking breaks. Pages that were once easily discoverable may become invisible to both Google and your users.
4. Backlink Integrity
Backlinks are one of your site’s strongest SEO assets—but they’re only valuable if they lead somewhere. If high-authority sites are linking to pages that no longer exist, and you haven’t set up proper 301 redirects, you’re wasting valuable link equity. A migration without a backlink audit is like moving house and forgetting to forward your mail.
5. Lead Generation and UX
User experience is at the heart of conversions. If visitors land on broken pages, face inconsistent layouts, or can’t find what they’re looking for, they’ll leave—and they won’t come back. Migrations can disrupt contact forms, CTAs, tracking scripts, and more. Even a short-lived UX issue can affect sales, sign-ups, and engagement metrics.
Why Strategy Is Non-Negotiable
Without a comprehensive, step-by-step migration plan, things slip through
the cracks—redirects are missed, metadata is lost, content disappears, and
rankings plummet. And unlike design tweaks, SEO losses aren’t always easy to
reverse. What took years to build can vanish in a week.
That’s why strategy is everything. A well-executed migration doesn’t just
protect your current performance—it can actually improve it. When done
right, it gives you the opportunity to:
• Improve page speed and mobile experience
• Upgrade technical SEO
• Realign user journeys
• Strengthen your site's structure for future scalability
At Connective9, we approach migrations as high-impact projects, not back-end
tasks. Every migration is backed by cross-functional collaboration between
SEO, tech, design, and analytics—so nothing gets missed, and everything is
set up for success.
Because in digital marketing, the only acceptable kind of migration is one
that moves you forward.
The Ultimate Website Migration Checklist
Phase 1: Pre-Migration Planning
1. Define the Type of Migration: Domain change, CMS switch, HTTPS upgrade, structural revamp? Identify what’s changing—and what isn’t.2. Benchmark Your Current Site: Track current performance: traffic, top URLs, backlinks, index coverage, rankings.
Tools: Google Analytics, Search Console, Ahrefs, Screaming Frog
3. Crawl Your Existing Website: Export a full sitemap and page-level data like meta titles, canonicals, internal links, and status codes.
4. Map Out URL Changes: Create a 1:1 redirect map (old URLs to new). Prioritise SEO-rich pages and eliminate orphaned ones.
5. Back Up Everything: Ensure a full backup of your site—files and databases. Keep staging and production separate.
6. Set Up a Staging Site: Test migration privately. Block search engines from crawling it using robots.txt or meta noindex.
Phase 2: Technical SEO Setup Pre-Launch
1. Update Internal Links: Ensure all internal references point to new URLs.2. Check Canonical Tags: Update them to reflect the final URLs to avoid duplicate indexing.
3. Verify Robots.txt and Meta Robots: Ensure key pages aren’t blocked. No accidental disallow rules.
4. Update Structured Data: Carry over schema markup and test for errors using Rich Results Test.
5. Create and Test Redirects: Implement 301 redirects. Avoid chains and loops. Validate with tools.
6. Generate New XML Sitemap: Reflect only the new URLs. Submit to Search Console after launch.
Phase 3: Migration Launch
1. Remove Noindex/Disallow Directives: Make your site crawlable and indexable before going live.2. Switch DNS/Go Live Strategically: Launch during low-traffic windows. Monitor uptime and response codes.
3. Check Mobile Friendliness & Speed: Test Core Web Vitals, responsiveness, and speed performance.
4. Reinstall Analytics and Tracking Tags: Validate GA4, GTM, Meta Pixel, and all tracking integrations.
5. Set Up Google Search Console: Add new property, submit sitemap, inspect pages, and fetch critical URLs.
Phase 4: Post-Migration Audit
1. Run a Sitewide Crawl: Compare with pre-migration data. Look for redirect chains, broken links, or missing pages.2. Monitor Traffic and Rankings: Expect fluctuations. Monitor daily for the first 30 days.
3. Audit 404 Errors and Fix Redirects: Resolve broken links fast. Update sitemap if needed.
4. Update Backlinks Where Possible: Contact high-value sites linking to old URLs and request updated links.
5. Reinforce Internal Linking: Link new pages strategically to boost crawl depth and page equity.
6. Communicate the Change: Update your audience via blog, social media, newsletters, and PR if needed.
