Migrating a WordPress site to a new domain looks simple until Google stops smiling at you. You change DNS, update URLs, check that the homepage loads, breathe for a second and, three days later, the fun begins: pages disappearing from the index, organic traffic dropping without asking permission, internal links still pointing to the old domain and some SEO plugin proudly doing the wrong thing at scale.
A domain migration is not verified by opening the site in a browser. That only proves Apache, Nginx or LiteSpeed is still alive. SEO has to be checked with data, crawls, redirects, logs and far less blind faith than people usually bring to this kind of job.
In this article I will explain how to verify whether your WordPress SEO is still intact after changing domains. Not from the pretty theory side, but from that grey area where a company asks why leads stopped coming in and you discover half the site returns 302s, canonicals point to the old domain and the sitemap looks like it was built during a rushed office move.
The best way to know whether SEO survived a migration is to have a clear snapshot of the before. It sounds obvious, but many migrations start with an email like: we are changing the domain tomorrow, can you take a quick look? Sure. I can also inspect the engine after throwing the car off a cliff.
Before touching anything, you should save at least this information:
If you do not have that previous snapshot, you can still audit the situation, but you are no longer comparing. You are investigating an accident without security cameras. It can be done, but it takes longer and involves more assumptions.
If you need a solid starting point to understand whether a WordPress installation is performing properly in search, this guide on why your WordPress site is losing traffic and how to fix it is a useful companion before and after a migration.
In a domain migration, 301 redirects are the bridge between the old site and the new one. If that bridge is poorly built, Google will not cross it. Users will not either, and sometimes we forget that behind SEO there are people trying to buy, book, read or contact someone.
The correct approach is for each old URL to redirect to its exact equivalent on the new domain. Not everything to the homepage. Redirecting everything to the homepage is fast, yes, just like fixing a leak by placing a bucket underneath. It does not solve the problem.
After migration, crawl the site with Screaming Frog, Sitebulb or even your own curl scripts if you enjoy controlled suffering. Check that there are no redirect chains such as HTTP to HTTPS, old domain to new domain, non-slash to slash and then another hop to the final canonical URL. Every hop adds friction.
A quick terminal check:
curl -I https://olddomain.com/important-url/
You want to see a direct 301 to the correct URL on the new domain. If you see 302, 404, 500 or a redirect to a generic page, it needs fixing.
For the operational side of changing a WordPress domain, it is also worth checking this article on how to migrate WordPress to another domain, because many SEO problems are born from a technical migration done halfway.
WordPress stores URLs in more places than it seems: options, content, widgets, builders, metadata, menus, shortcodes, plugin tables and, if the project has been around for years, probably in some corner nobody remembers. A quick database replacement can solve a lot, but it can also break serialized data if done carelessly.
On serious projects I usually review:
siteurl and home in the wp_options table.Tools like Better Search Replace, WP-CLI search-replace or a well-managed migration with Duplicator Pro, All-in-One WP Migration or custom scripts help. But they do not replace review. The tool executes; the judgment is yours.
After migrating a WordPress domain, Search Console is your control room. It is not enough to see whether clicks go down. You need to understand what is happening with indexing, sitemaps, canonical pages and crawl errors.
In a clean migration, you should:
An initial drop can be normal. Google needs to recrawl, process redirects and update signals. What is worrying is seeing systematic errors: old URLs without redirects, new pages blocked by robots.txt, canonicals pointing to the previous domain or a sitemap with mixed URLs. That is no longer fluctuation; that is technical mess with commercial consequences.
If you have already lost traffic during the migration, this guide on recovering lost WordPress traffic can help you organize the diagnosis without falling into the classic strategy of touching everything to see what happens.
Three small things can ruin a migration: a wrong canonical tag, a forgotten noindex directive and a sitemap pointing to the old domain. They are silent errors. The site loads, the client sees nothing strange and you may take weeks to detect that Google is receiving contradictory signals.
Check at least the important URLs one by one:
noindex.HTTPS also deserves attention. I have seen migrations where the new domain works, but some assets still load from HTTP or from the old domain. The result: mixed content, security warnings and strange signals for search engines. If you want to reinforce that part, here is a clear explanation of why using HTTPS instead of HTTP matters.
SEO plugins are useful. Very useful. But they are not infallible auditors. Rank Math, Yoast or SEOPress can generate sitemaps, canonicals and metadata, but if the base configuration is wrong or the migration left leftovers, the plugin may simply automate the mistake with admirable efficiency.
After changing domains, manually review title templates, meta descriptions, Open Graph, schema, breadcrumbs and canonical URLs. Especially if there is WooCommerce, custom post types, languages or ERP integrations. In an online store, a badly redirected category can mean losing sales across an entire product family. And no, Google does not always send a polite letter.

A migration can keep rankings and still hurt the business. How? Easy: broken forms, missing Analytics events, thank you pages not configured, pixels pointing to the old domain, payment gateways with outdated return URLs or CRM integrations that stop receiving leads.
So, besides pure SEO, review:
Technical SEO does not live in isolation. If traffic arrives but does not convert, the migration is still wrong from a business perspective. Sometimes the issue is not Google, but that undocumented webhook that had been working for three years by pure luck.
The migration does not end the day you change the domain. Actually, that day the boring part begins: monitoring. And if something boring repeats itself, automate it.
You can set up periodic checks with cron, PHP scripts, Python, Laravel Console Commands or n8n workflows. The idea is simple: review critical URLs, check HTTP status codes, validate canonicals, detect sitemap changes and send alerts if something breaks.
In business projects I usually recommend a list of critical URLs: homepage, main categories, service pages, top-selling products, posts that bring traffic, lead generation pages and URLs with strong backlinks. You do not need to crawl 40,000 URLs every hour. You need to know quickly if the pages that pay the bills stop responding properly.
A good migration is not the one with no problems. It is the one with enough controls to detect problems before the client, Google or the bank account notices them.
After quite a few migrations, patterns repeat themselves. Not because WordPress is bad, but because invisible work is underestimated.
Some of these failures appear in other maintenance contexts too. That is why it makes sense to read about the most common WordPress errors, because many migrations simply expose problems that were already there, waiting for their dramatic moment.
When you migrate a WordPress domain, you are not just changing an address. You are moving years of signals: links, authority, content, history, trust and user behavior. If you do it well, the impact should be controlled and temporary. If you do it badly, you can lose in a week what took years to build.
The professional way to verify that SEO is still intact is not to stare hopefully at a chart. It is to audit redirects, indexing, canonicals, sitemaps, Search Console, performance, conversions and logs. It is combining technical judgment with business sense.
And above all, it is accepting one uncomfortable truth: a migration is not finished when the website loads. It is finished when Google understands the change, users land where they should and the business keeps working without needing creative explanations for traffic drops.
