How long domain migrations take to recover organic traffic

Domain migrations, moving a site’s content to a new domain and redirecting the old one, carry a known SEO risk, but how long the risk actually lasts has mostly circulated as folklore. Search Engine Journal contributor Dan Taylor ran a real, large-scale study of it: 892 tracked domain migrations, each measured for how many days the new domain took to reach the same estimated organic traffic the old domain had. We read the study directly. Here is what it found.

The headline number#

The average across the 892 migrations was 523 days, about 17 months, for the new domain to match the old domain’s organic traffic. That average sits on top of real spread, not a tight cluster. The shortest recovery times recorded were 19, 22, 23, and 33 days. At the other end, 17% of the migrations in the sample had not returned to their pre-migration traffic level even after 1,000 days of tracking. A smaller group, 25 migrations (2.8%), were marked inconclusive: traffic reached the old domain’s level but never stabilized there.

That range matters more than the average by itself. A site planning a migration around “expect roughly a year and a half” is planning around the middle of a distribution that also contains a three-week recovery and a one-in-six chance of never getting there.

The same author ran an earlier version of the study in 2023, on 171 migrations, and reported an average of 229 days with 42% not returning to their old traffic level. The 2024 run expanded the dataset to 892 migrations and the average rose to 523 days. The two samples are not like for like, so the rise shows a larger and more varied dataset, not that migrations got slower.

What the study says about speed#

The study does not report what the fastest migrations, at 19, 22, 23, and 33 days, did differently. Taylor’s own advice, drawn from experience rather than from the dataset, is to launch the new domain and URL structure 24 to 48 hours before implementing the redirects: Google rebuilds its index page by page, so it has already begun crawling the new paths in most cases. Using Google Search Console’s change of address tool, he adds, can smooth a lot of early migration lag.

On the slow side, a community member, Natalia Witczyk, proposed that recovery lag tracks backlink profiles: the profile has to be recrawled and the redirects reflected, which takes longer when it is extensive. Taylor then checked each domain’s referring-domain count and found some correlation, but with “a large number of outliers,” likely due to how the migration was carried out.

Why we care#

The number worth planning around here is not 523, it is the range around it: weeks at the fast end, over 1,000 days and still not recovered for 17% of sites at the slow end, from the same set of migrations. The study does not explain what separated the two groups, so treat its timeline as a range to plan for, not a promise, and read Taylor’s launch-ahead and change of address advice as experience, not a measured result.
