A business owner can protect visibility after a domain move by checking the new domain’s index coverage and confirming the Change of Address setup for both www and non-www versions. A real case shows how a migration can appear successful, then reverse four months later.
The owner changed domains at the beginning of 2026 to cover an additional topic, added redirects and used Google Search Console’s Change of Address tool. By April, traffic had recovered and the new domain had about 5,000 impressions per day, according to the account summarized by Barry Schwartz.
About four months later, more than 5,000 pages on the new domain appeared in Search Console as "Crawled, currently not indexed." Impressions on the new property fell to about 20 per week, while the old domain was fully re-indexed and received the impressions and clicks again.
What happened during the domain migration?
The reported sequence matters because the new domain had already recovered traffic before the reversal. The owner had implemented redirects and submitted the Change of Address information, so the case did not begin with an obviously incomplete setup.
The new domain’s status indicates that Google had crawled the affected URLs but did not keep them indexed. That is different from a page that Google has not discovered. The old domain’s reappearance is the part that affects brand visibility, because search impressions and clicks reportedly shifted back to it.
John Mueller, who responded in the discussion, asked the owner to send details directly and said: "Sometimes things just take a particularly long time to be fully processed." He also said the Change of Address setting should be configured for both the www and non-www versions so the migration can complete.
Why can indexing and traffic recover on different timelines?
Google’s site-move guidance says a medium-sized website can take a few weeks for most pages to move into the index, while larger sites can take longer, according to a review of the guidance by DreamHost. That describes the indexing stage, not a guarantee that rankings and organic traffic have returned to the pre-migration level.
A June 26, 2026 analysis by SALT examined 1,052 domain migrations. It found a median recovery time of 304 days and a mean of 489 days, based on the point at which monthly organic search traffic equaled or exceeded the old domain’s pre-migration baseline. The same analysis reported that 22.8% of migrations were back at the pre-migration traffic level after 90 days, 27.8% after 120 days, 42% took longer than 12 months, and 13.9% did not reach that level within three years.
Those figures describe estimated organic traffic and are not a promise for an individual site. SALT’s analysis covered moves from one domain to another using 301 redirects, and the researcher said the data was descriptive rather than causal. It does not establish why one migration recovered faster than another.
A 2025 Search Engine Journal study cited by DreamHost analyzed 892 migrations and found that 17% had not recovered their estimated organic traffic after 1,000 days, with average recovery taking 523 days. The study used estimated organic traffic from third-party SEO tools rather than each site’s own analytics, so its results should be read as an estimate.
What could cause a delayed reversal?
The source reports a theory from Marie Haynes that a migration can prompt a fresh quality assessment. In the cases she described, Google had crawled the pages but did not index them, and the sites’ content did not offer something original compared with pages already ranking for the same queries.
That remains a practitioner theory and not a confirmed explanation for this case. Google guidance emphasizes original content that demonstrates effort or skill. A business moving a domain can therefore have a technically sound migration while still needing to review whether each new page adds information that is genuinely distinct from what already ranks.
The source also raises the possibility of an issue on Google’s side. John Mueller’s observation that some migrations take a long time to process does not identify why this particular old domain returned.
What to do now
- Check both versions of the new domain. Confirm that Change of Address is configured for the www and non-www versions in Search Console.
- Review the index coverage report. Filter for "Crawled, currently not indexed" on the new domain.
- Compare impressions across domains. Compare the new and old domains in Search Console to confirm whether impressions and clicks have shifted back to the old property.
- Check the pages that lost visibility. Compare them with pages already ranking for the same queries and review whether they add original information.
- Keep monitoring recovery beyond the first weeks. Record indexing, rankings, impressions and organic traffic separately, because the research describes different recovery stages and large variation between sites.

How should a business interpret the case?
A successful migration can remain visible in Search Console without proving that it is permanently stable. Indexing, rankings and traffic are distinct. A page can be indexed, rank for a time and then lose visibility as Google reassesses the site or changes which domain it serves.
For business owners, the practical lesson is to monitor the new property after traffic returns instead of treating recovery as the end of the migration process. The source does not establish that the 5,000-page reversal was caused by the www setting, content quality or a Google issue. It establishes that a business should check all three possibilities while tracking indexing and traffic over time.
FAQ
Why is Google showing my old domain again after a migration?
In the reported case, the new domain first recovered traffic, but four months later Google marked more than 5,000 pages as "Crawled, currently not indexed" and showed the old domain again. The source does not establish a single confirmed cause. John Mueller said some migrations can take a long time to process and recommended checking Change of Address for both www and non-www.
Do I need to submit Change of Address for both www and non-www?
John Mueller recommended confirming that Change of Address is set up in Search Console for both the www and non-www versions so the domain can fully migrate.
How long does it take Google to fully process a domain migration?
Google’s guidance says a medium-sized website can take a few weeks for most pages to move into the index, while larger sites can take longer. SALT’s analysis of 1,052 domain migrations found a median traffic-recovery time of 304 days and a mean of 489 days, while a 2025 study of 892 migrations cited by DreamHost found average recovery at 523 days. These are research estimates, not guarantees for an individual site.
