5 Things to Check When a Website is Being Migrated
Website migrations are not as uncommon as you think. Website migrations can consist of domain changes, moving to a new hosting provider, switching your CMS, or even just redesigning your website.
Migrations are sensitive, though. Even small mistakes in the migration process can result in indexing issues or broken pages. That can result in lost traffic and poor SERP rankings.
From an SEO and site owner perspective, that’s highly undesirable. The goal is simple: complete the migration without disrupting user experience or search visibility.
So, here are some simple checks you can do to ensure that your migration is successful.
Make Sure Redirects Are Properly Configured
One part of the website migration is putting redirects on old URLs. When you are doing a website migration, people will still search for your website using the old URLs. So, you need to add redirects that automatically send them to the new URL.
If old URLs are not redirected correctly, users may land on 404 pages, and search engines may treat the new pages as completely different content. That can cause rankings and link equity to disappear almost overnight.
Nobody wants that because it makes the time and effort you put into your website to make it rank high kind of useless. With proper migration, you can preserve the benefits.
So, before launching the migrated site, make sure to:
map old URLs to their new versions,
implement proper 301 redirects,
and test important pages manually.
Also, make sure to pay extra attention to:
blog posts,
service pages,
category pages,
and high-traffic landing pages.
A single missed redirect on important URLs like these can impact both SEO performance and user trust.
Check DNS Propagation and Validate DNS Records
One of the most overlooked parts of a migration is DNS configuration. Whenever you point your domain to a new server or hosting provider, there is a waiting time before the changes go live. This waiting time is called DNS propagation delay.
During this period, some users may see the old version of the site while others see the new one. The delay occurs because the new DNS records for your domain need time to be relayed to the global DNS servers.
It can take around 24 to 72 hours for the propagation to complete. You can monitor the propagation with a DNS propagation checker.
Once propagation is complete, you also need to validate your new records. Any mistakes in the records can lead to website downtime or broken pages and links.
To validate records, you can use a DNS record lookup tool. All you have to do is enter your domain name, and the tool will list all the records it can find from the public DNS network. Then you compare the records with the ones in your domain management panel.
If there are any problems, you have to fix them either yourself or by contacting your hosting provider.
Audit Internal Links and Broken Pages
Once you have checked your DNS records, you need to check your website for broken links and pages. So, a link audit is next in line. Migrations often break internal links without anyone noticing immediately. For example, image links change, and other links may break because they reference directories that no longer exist.
Problems like these hurt crawling and user experience, which can result in poor rankings.
To do an audit, you must:
Crawl the website
Identify 404 errors
Review XML sitemaps
Review breadcrumb links
Review image references
Check navigation menus
You can do most of that with the help of a broken link checker tool. These tools can automatically crawl your site to look for these errors.
Monitor Indexing and Crawl Activity
Once the migration is complete, do not assume Google will process everything perfectly on its own. It is highly likely that some of your pages will get unindexed. So you need to keep an eye on things. In particular, you should monitor the following:
indexed pages,
crawl errors,
coverage reports,
and ranking fluctuations.
Google Search Console is your best friend here. It becomes especially important during this stage because it can help you keep an eye on all of the mentioned stats.
Just remember, temporary ranking volatility is normal after a migration. You should be worried, though, when major indexing losses occur because they usually indicate a technical problem that needs immediate attention. At that point, you should do an audit of your technical setup.
Test Website Performance Across Devices and Regions
After a site migration, you also want to test the website again on different types of browsers and devices. That’s because a migrated site can technically work, but also perform poorly for various users.
Here’s a quick checklist of what you need to test to gauge performance.
mobile responsiveness,
page speed,
Core Web Vitals
and server response times.
These are the technical aspects. Then you also need to check the user experience aspects, such as the following:
forms,
login pages,
checkout flows,
and interactive elements.
These are all small things that can mar the user experience. They also don’t get caught in automated audits. So you must do this manually.
Final Thoughts
Website migrations require much more than simply moving files from one server to another. From an SEO perspective, every technical detail matters.
Redirects, DNS propagation, indexing, internal linking, and performance checks all play a role in protecting search visibility during the transition.
Using tools like DNS record lookup utilities, crawl auditors, and IP-based testing solutions can make the migration process far safer and easier to manage.
A successful migration is not just about launching the new site. It is about preserving rankings, maintaining accessibility, and ensuring users never notice that the move happened at all.
