SEO Migration (Domain Change): when the phones go quiet after a launch
Late on a Tuesday afternoon, a regional service company called us because their website had just moved to a new domain over the weekend. The site was up, the old address still resolved, and the new branding looked fine. But by Monday morning the owner noticed something odd: form fills had dropped, calls from organic search were down, and a few customers were landing on old pages from bookmarks and search results. That is the kind of problem that turns a normal domain change into a revenue problem fast.
Our first step was to get the timeline straight. We asked when DNS was changed, whether the old domain was still registered, if 301 redirects had been put in place, and whether Google Search Console and analytics had been updated. We also checked whether the site had moved at the same time as a redesign or platform change, because that often adds crawl issues, broken links, and duplicate content into the mix. In an SEO migration, the details matter more than the launch announcement.
The business owner did what most owners do: they assumed the web team had handled the SEO side. The web team had changed the domain, but there was no full redirect map, a few high-traffic URLs were returning 404s, and the canonical tags still pointed at the old domain on some templates. Search engines had started to re-crawl the site, but they were seeing mixed signals, which can slow down index transfer and traffic recovery.
What we checked during the first hour
We started with the basics: DNS records, SSL certificates, and whether the old domain still had active hosting. Then we crawled both domains with a site audit tool and compared response codes across the top landing pages, service pages, and blog content. The goal was simple: make sure every old URL returned a clean 301 redirect to the most relevant new URL, not a chain of redirects or a generic homepage bounce.
We also reviewed Google Search Console for both properties. That meant checking coverage reports, sitemap submissions, page indexing status, and any spikes in excluded or duplicate pages. In analytics, we looked for a drop in organic sessions, changes in landing page performance, and whether referral data was being preserved. If the site had a change in tracking ID during the migration, we made sure the new property and events were tied correctly so the owner could trust the numbers.
On the technical side, we checked the server rules first. Depending on the stack, that could mean Apache .htaccess rewrite rules, Nginx redirect blocks, or platform-level redirect settings in a CMS or host panel. We verified that the redirects were permanent 301s, not 302s, and that the new site used consistent canonicals, updated internal links, and a correct XML sitemap listing only the new domain. We also confirmed robots.txt was not blocking important pages during the move.
Fixing the migration without making things worse
Once we had the problem mapped out, we built a redirect matrix. That is a simple list of old URLs on one side and the matching new URLs on the other. The important part is being exact: service pages go to their equivalent service pages, blog posts go to the same articles, and old PDF or resource links get mapped individually instead of dumped to the homepage. That preserves relevance and reduces bounce from search traffic.
We then corrected the site signals. Canonical tags were updated to the new domain, internal navigation was rewritten so the site stopped pointing back to the old address, and the XML sitemap was regenerated and resubmitted in Search Console. Where needed, we updated HSTS and SSL settings so the old domain would cleanly force HTTPS before redirecting. We also checked for mixed content, because a domain change can expose old asset URLs that still load images or scripts from the previous host.
Because this was an emergency call, we kept the old domain live long enough to protect existing links and bookmarks. We did not decommission anything until the redirects were stable, the crawl errors stopped climbing, and the most important landing pages were being indexed under the new domain. That is the part many businesses miss: a migration is not finished when the site looks right in a browser. It is finished when search engines and users can both find the right page without friction.
Monitoring traffic recovery and documenting the handoff
After the redirect fixes were in place, we set up a monitoring window. We watched crawl errors, 404 logs, redirect response times, and indexed page counts over the next several days. In analytics, we compared organic traffic by landing page, not just total sessions, because recovery usually starts with top pages first. We also checked branded search queries, since those tend to rebound before broader keyword traffic does.
We documented every change we made: DNS updates, redirect rules, sitemap submissions, canonical corrections, and any template or CMS settings that had to be changed. That gave the owner a clean record for future maintenance and made it easier for their web vendor to avoid repeating the same mistakes. We also left a short list of pages to watch, including high-value service pages and any URLs that had been linked from partner sites or print materials.
By the end of the week, the site was stable, search engines were following the new domain, and the traffic drop had started to level out. Recovery after a domain change is rarely instant, but it should be measurable. The owner had a clear view of what was fixed, what still needed time, and which signals mattered most. That is the real value of an SEO migration: not just moving the website, but keeping the business visible while the move settles in.
