Migrating your website from one platform to another can feel like packing up your house while Google’s watching. One wrong move, and suddenly your rankings, traffic, and leads seem to disappear along with the old site.
The good news is that a website migration doesn’t have to hurt your SEO. With the right planning, you can move from Wix, Squarespace, Shopify, or GoDaddy to WordPress, preserve your rankings, and even end up with a faster, more flexible website.
I whipped up this how-to guide so you can migrate to a more befitting platform while preserving, even improving, your search rankings. It’s literally a practical website migration SEO checklist, but let’s start with the basics.
Why Website Migrations Can Hurt SEO (If You Rush Them)
Search engines don’t care whether you’ve upgraded your website or completely rebuilt it. They care whether they can still find, crawl, and understand your pages.
They’ve already crawled your site and had your site map before, so do you want it to have to figure your site out all over again? If not, then you can’t change too much too soon.
What Google Sees During a Migration
When I migrate a website, I focus on preserving the signals Google already trusts.
Google identifies every page by its URL. If that URL changes without a proper redirect, Google may treat the new page as something entirely different. Years of authority can disappear overnight.
The same applies to your content. Rewriting every page during a migration makes it harder for Google to recognize that the new page serves the same purpose as the old one.
Do you see why I always recommend keeping your core content, headings, and metadata as consistent as possible during migration?
Internal links matter, too. They help search engines discover pages and understand how your website is organized. Broken or outdated links create dead ends for visitors and search engine crawlers. Find out how to find & fix broken links.
Finally, Google expects a website to be accessible. If pages return errors, take too long to load, or aren’t indexed after launch, rankings suffer until those issues are fixed.
Common Migration Mistakes That Cause Ranking Drops
Most migration-related SEO problems are caused by skipping the preparation. For example, most website owners make a crucial mistake of initiating migration before setting up 301 redirects.
Consequently, search engines can’t pass the link equity from the old website to the new one, leading to significant ranking drops.
Another common mistake is deleting pages that have earned rankings and backlinks. Even pages that receive little traffic can contribute valuable authority to your website.
I’ve also seen businesses:
- Change their URLs.
- Rewrite all their content.
- Redesign the site.
- Switch domains in a single launch.
How can they tell what’s behind their traffic drop when everything changes at once?
The good news is that nearly all of these problems are preventable. A structured migration plan keeps Google connected to the SEO value you’ve already built instead of forcing it to start from scratch.
Choose the Right Migration Strategy Before You Start
Moving a five-page brochure site from Wix to WordPress isn’t the same as transferring a Shopify store with hundreds of products. The more you understand what needs to move, the smoother the process will be.
Platform-to-Platform Migrations
Some platforms make exporting your website easy while others require a little more manual work.
A Wix to WordPress migration usually involves rebuilding pages in WordPress while exporting your content, images, and blog posts where possible.
If you’re planning to migrate Wix to WordPress, pay close attention to your URLs. Wix and WordPress often use different URL structures, so you’ll likely need redirects to preserve your rankings.
Don’t focus solely on moving the content. Your metadata, image alt text, internal links, and redirects deserve just as much attention. On that note, here’s a resource for you: “Wix vs. WordPress: Which One Should You Choose?“
If you’re learning how to migrate Squarespace to WordPress, you’ll find that Squarespace can export much of your content. Even so, you’ll still need to rebuild parts of the site, verify that every page has transferred correctly, and recreate anything the export doesn’t include.
Shopify to WordPress Migration
This migration is more complex than the couple we just discussed, as you need to account for:
- Product pages.
- Collections.
- Customer data.
- Ecommerce functionality.
Unless you’re replacing Shopify with another ecommerce platform like WooCommerce, this migration takes more planning than a standard business website.
No matter which platform you’re leaving, don’t assume the migration is complete because the new site looks right. A successful migration preserves the SEO value behind the design, not just the design itself.
When You Should Keep Your Existing URLs
Let me share the one shortcut I recommend for every migration: keep your URLs the same whenever possible.
Google may not even realize that you moved your content if you can manage to preserve your original URLs. Existing backlinks continue working, bookmarks remain valid, and visitors reach the right page without being redirected.
Sometimes changing URLs is unavoidable, especially when moving between platforms with different permalink structures. When that happens, create a one-to-one 301 redirect from every old URL to its closest matching page.
Avoid sending dozens of pages to your homepage or a generic category page. Google values relevance, and your redirects should reflect it.
Website Migration SEO Checklist Before You Move
The easiest SEO problems to fix are the ones you prevent before launch. I never start a website migration without intimately studying the current site and mulling over how to preserve its most valuable elements.
1. Crawl and Save Every Existing URL
Start by creating a complete list of your current URLs. A crawler like Screaming Frog can export every page, image, redirect, and status code on your website.
This list becomes your migration roadmap. Without it, it’s easy to overlook pages that still receive traffic, have valuable backlinks, or rank for important keywords.
2. Back Up Your Website
Due diligence demands that you create a full back-up before you start migrating. Hopefully, you’ll never need it, but if something goes wrong during the migration, a backup lets you restore your site instead of rebuilding it from scratch.
3. Export Metadata
Your page titles, meta descriptions, image alt text, and structured data all contribute to SEO.
Many website owners remember to copy the content but forget the metadata. Recreating dozens or hundreds of optimized titles after launch is a frustrating way to spend your week.
4. Record Current Rankings and Traffic
How can you objectively compare all website elements after migration unless you take screenshots before you begin. That’s your benchmark for troubleshooting and meeting band standards.
Use Google Search Console and Google Analytics to export your:
- Top-performing keywords.
- Organic traffic.
- Indexed pages.
- Landing pages.
Once the new site is live, you’ll have a reliable baseline for measuring the migration’s impact.
5. Create a Redirect Map
Every page that changes URLs should have a destination before launch. I usually build a simple spreadsheet with two columns, one for the old URL and another for the new URL.
Once every page has a matching destination, implementing 301 redirects becomes much more straightforward.
6. Benchmark Site Speed
A migration is the perfect opportunity to improve performance rather than carry old problems into the new website. So, record your current Core Web Vitals, page speed scores, and load times.
After launch, compare those numbers to make sure the new site is performing at least as well as the old one.
How to Migrate Your Website Without Losing Google Rankings
You’re not yet done with the preparation, but you’re doing great so far. You still have a few things to do so that your new website will launch successfully without losing your hard-earned Google rankings.
1. Build the New Site Before Going Live
If you can, build your new website on a staging domain or development server so you can test layouts, forms, navigation, and SEO settings without affecting your live website.
It also keeps search engines from indexing unfinished pages before you’re ready to launch.
2. Keep Important Content Intact
Again, you want to preserve the primary content of all pages that rank well. You can always refresh the copy after the migration is complete and your rankings have stabilized.
Think of the migration as moving your furniture into a new house. Rearranging everything can wait until you’ve finished unpacking.
3. Match Page Titles and Metadata
Your page titles and meta descriptions help Google understand what each page is about.
If they’re already performing well, carry them over to the new site. The same goes for image alt text, canonical tags, and structured data. These details are easy to overlook, but replacing them after launch is far more difficult.
4. Set Up 301 Redirects Correctly
In the previous section, we prepared a redirect map; now is the time to implement it and avoid redirect chains, which slow down crawlers by creating unnecessary complexity. Each old URL should redirect directly to its final destination in a single step.
After implementing your redirects, test them. A redirect that exists on paper doesn’t help if you configure it incorrectly.
5. Test Everything Before Launch
Before making the new website public, perform one final walkthrough. Check for:
- Broken links.
- Missing images.
- Crawl errors.
- Duplicate pages.
- Forms that don’t work.
Verify that redirects behave as expected and confirm that search engines are blocked from indexing the staging site. Also ensure the search engines aren’t blocked once the site goes live.
These extra minutes you spend testing will save you weeks of troubleshooting afterward.
What to Do Immediately After Launch
Launching your new website is only the beginning of the monitoring phase. You want to catch any small issues that could grow into major SEO problems in the first days of launch.
Here’s what you want to do immediately after you go live.
1. Submit Your XML Sitemap
Once your new site is live, generate a new XML sitemap and submit it via Google Search Console.
The new sitemap will help Google to discover your pages faster and understand your new site structure. If your sitemap still contains old URLs or missing pages, fix it immediately and resubmit it.
2. Check Google Search Console
Google Search Console should become your best friend after a migration. It’s a great tool for website health checks, as you can use it to pinpoint:
- Indexing issues.
- 404 (Page Not Found) errors.
- Crawl errors.
- Broken redirects.
- Server errors.
- Pages blocked by robots.txt.
- Incorrect canonical tags.
Many of these problems have simple fixes, but they can limit your site’s visibility if they’re left unresolved.
It’s also worth checking the Coverage and Pages reports every day during the first couple of weeks. Small issues are much easier to fix before they affect a large portion of your site.
Here’s a resource for you if you’re not familiar with Google Search Console: “What is Google Search Console?“
3. Monitor Rankings and Traffic
Don’t be worried by traffic fluctuations after a migration because it’s normal. Google needs time to crawl, process, and reassess your website.
Compare your current performance with the benchmark you recorded before the migration. If traffic drops sharply or important pages disappear from search results, investigate the cause instead of assuming Google will sort it out.
A successful migration is measured by how quickly your rankings, traffic, and conversions return and, ideally, improve.
Recovering Lost Traffic After Site Migration
The best-planned website migrations can cause temporary ranking fluctuations. That doesn’t mean you’ve permanently lost your SEO.
The key is figuring out whether you’re seeing a normal adjustment or a problem that needs fixing.
1. Know What’s Normal
It’s common to see rankings bounce around for a few days or even a few weeks after a migration.
Google has to crawl your new pages, process your redirects, and update its index. During that time, some keywords may move up while others move down before settling into their new positions.
If your traffic drops slightly and then begins to recover, that’s usually part of the process.
2. Find Missing Redirects
The most common culprits behind traffic slumps are missing or incorrect redirects.
Compare your original URL list against the new website. Every page that used to exist should either have a matching page or a 301 redirect leading visitors and search engines to the most relevant alternative.
One missing redirect might not seem like a big deal, though it usually is. How about fifty missing redirects, though?.
3. Look for Indexing Problems
If Google isn’t indexing your new pages, they won’t appear in search results.
Check Google Search Console for pages marked as:
- Crawled – currently not indexed.
- Discovered – currently not indexed.
- Excluded.
These reports often pinpoint issues with:
- Duplicate content.
- Crawlability.
- Canonical tags.
- Accidental no-index settings.
You also need to check whether robots.txt isn’t blocking search engines from indexing the pages with indexing issues.
It’s like you left staging restrictions in place without realizing it.
4. Audit Internal Links
Redirects help visitors reach the right pages, but your internal links should point directly to those pages.
Update navigation menus, buttons, and links in your content to use the new URLs rather than relying on redirects. It improves crawling, reduces unnecessary redirect hops, and enhances the user experience.
5. Be Patient But Not Too Patient
If your rankings continue to decline after several weeks, or traffic hasn’t started to rebound, it’s time for a full SEO audit. Review your redirects, indexing, metadata, internal links, page speed, and content to identify what’s holding the new site back.
Most migration-related SEO problems have a logical cause. Once you find it, the solution is usually much easier than rebuilding your rankings from scratch.
Migrate Your Website With Confidence
A website migration doesn’t have to cost you years of SEO work. You now know what Google expects, so follow a structured migration plan to preserve the signals your site has already earned.
