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, and the spread behind it#

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, the point past which the study stops counting them as recovering at all. 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.

What separated the fast recoveries from the rest#

Taylor attributes the fastest recoveries, 19 to 23 days, to complete 1:1 redirect mapping covering every indexed URL, validated in staging before the domain switch, plus close monitoring for at least the first two weeks after launch. Launching the new URL structure with redirects live 24 to 48 hours before the full migration also comes up as a factor: it gives Google a head start crawling and processing the new paths instead of discovering them cold on migration day. Using Google Search Console’s change of address tool is cited as smoothing the earliest post-launch lag.

On the slow side, the study’s author reports a correlation between the size of a site’s backlink profile and how long recovery took, the reasoning being that every external site linking in has to be recrawled with the new destination reflected before that link value carries over. Taylor is explicit that this is a correlation with “a large number of outliers,” which he attributes to how individual migrations were actually carried out rather than backlink count alone.

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’s own account of what separated the two groups, full redirect coverage, pre-launch validation, and early monitoring, over partial or reactive redirect work, gives a domain migration checklist a publisher can act on before moving, not just a timeline to brace for afterward.
