TL;DR
- Search Engine Journal reported on 8 September 2026 that a UK news publisher lost almost all of its Google news visibility after moving from .co.uk to .com overnight.
- NewzDash measured its Search Visibility score falling about 98%, from 1% to 2% down to 0.02%, within two weeks of the switch.
- Four months on the report describes only isolated appearances and no recovery, while standard SEO tools showed roughly a 60% to 70% drop, per Shehata of NewzDash.
- The publisher is not named and the data is not public, so the figure cannot be verified, and core updates or technical problems may have contributed.
- John Mueller of Google has said a site move is always a big deal, even when it is done right.
A UK news publisher lost almost all of its visibility in Google news results after moving its site from a .co.uk domain to a .com. Search Engine Journal reported on 8 September 2026 that NewzDash, which tracks trending UK news queries, recorded the site's visibility collapsing within two weeks of the overnight switch and still showing no recovery four months later. The publisher is not named, and other factors may have contributed.
What was measured, and by whom
The measurement comes from NewzDash, a monitoring service that tracks trending UK news queries across Top Stories and organic results and turns that into a Search Visibility score. Search Engine Journal reported on 8 September 2026 that NewzDash had monitored the .co.uk domain for fourteen months before the migration, which is what makes the after figure readable at all: there is a long baseline behind it rather than a single before-and-after screenshot.
Across that baseline the site held between 1% and 2% visibility on the news queries the company monitors. John Shehata of NewzDash noted that similar-sized publishers usually sit between 3% and 6%, so the site was already below the band for its size before anything moved. Visibility fell during the migration and reached 0.02% two weeks later. The new .com domain did not pick up what the .co.uk lost.
Four months after the move, according to the write-up, the new domain showed only a handful of isolated appearances. No recovery had been reported as of publication.
The publisher is not named, and that matters
Search Engine Journal was explicit that the post does not name the publisher and does not share the underlying data, so the 98% cannot be checked independently. That is a real limit on what anyone should do with this story.
Search Engine Journal also reported that the site was already losing visibility during several core updates, and that internal technical problems likely contributed. The data does not show the domain switch was the sole cause. On top of that, the NewzDash score blends Top Stories and organic results and cannot separate the two, so the report cannot say which surface took the damage.
The article does not say whether the publisher used permanent redirects, submitted a Change of Address in Search Console, kept hreflang in place, or set any country targeting. Those are the details that would normally decide whether a migration was executed well, and none of them are on the record here.
Why two tools disagreed by roughly thirty points
The most transferable part of this story is not the 98%. It is that a second class of measurement, described by Shehata, put the same drop at roughly 60% to 70%.
Search Engine Journal reported Shehata's explanation for the gap: standard SEO tools follow a fixed list of keywords, most of them evergreen, while NewzDash tracks a changing set of trending news queries. A rank tracker built on a stable keyword set will report what happened to stable keywords. If a publisher's real revenue sits on queries that only exist for two days at a time, a fixed keyword list is measuring the calmer half of the site and reporting it as the whole.
The practical version of that: a migration can look survivable in one dashboard and close to fatal in another, at the same moment, on the same site. Which dashboard is on the screen when the decision to proceed or roll back gets made is not a small detail.
The figures Search Engine Journal reported on 8 September 2026 sit like this.
| Measure | Before the move | After the move |
|---|---|---|
| NewzDash Search Visibility score on trending UK news queries | 1% to 2% | 0.02% two weeks after the switch, a fall of about 98% |
| Monitoring window | Fourteen months before the migration | Four months on, only isolated appearances and no recovery |
| Standard SEO tools, per Shehata's estimate | Not stated in the report | Roughly a 60% to 70% drop |
| Typical visibility for similar-sized publishers, per Shehata | 3% to 6% | Not stated in the report |
What Google's own guidance says about moving a domain
Search Engine Journal summarised Google's site-move documentation alongside the case. The guide treats a domain change as a standard type of site move and covers mapping old URLs to new ones, setting up redirects, submitting a Change of Address in Search Console, and monitoring URLs afterwards. Google states that permanent redirects do not harm PageRank and that each URL change is processed separately.
The same guidance warns about the waiting period. Ranking can fluctuate during recrawling, and for medium-sized sites it can take weeks or longer for new URLs to appear in results, with larger sites potentially taking more time. Google's advice for large sites is to test one section first, ideally a section that does not update often, and to avoid combining a domain move with a CMS change or a redesign.
For Google News specifically, Search Engine Journal reported that Publisher Center guidance points to the same process, and adds updating the News sitemap when site structure changes, making sure Google's crawler can read the site easily, and avoiding long redirect chains. Neither page states how news-specific signals carry across when a site changes domain, which is exactly the gap this case sits in.
Search Engine Journal also quoted John Mueller of Google, who told a Reddit user weighing a .ca to .com move for branding reasons that "A site move is always a big deal", even when it is done carefully.
Shehata's reading, and where it goes past the documentation
Search Engine Journal reported that Shehata attributes the collapse to what he calls a "Google Reset", his own term rather than Google's, in which drastic changes such as a CMS switch, a redesign or a domain change prompt Google to reevaluate a site. He argues that news surfaces weigh hostname-level signals such as publication history and editorial trust, and that a 301 redirect passes link equity but may not carry that history.
Search Engine Journal was careful to mark the boundary: Google's guide does not say news history is hostname-based. Shehata's recommendation to move content in sections matches Google's advice for large sites, but his second recommendation, waiting for the new domain to appear in Google News before completing the switch, is not covered in Google's guidance. It is a reasonable inference from the case rather than a documented instruction.
Who should read this as a warning, and who should not
The sites with the closest exposure are the ones whose traffic depends on queries that appear and disappear inside a news cycle: publishers, media brands, and any business running a newsroom-style content operation where freshness is the ranking asset. For them, the gap between the two measurement methods is the story.
An ecommerce catalogue or a service business whose demand sits on stable, evergreen queries is in a different position. Google's guidance on redirects and Change of Address still applies, and the standard tooling will describe the outcome reasonably well because the query set genuinely is stable. This case does not say that domain moves are unsafe. It says that one publisher's news search visibility went to near zero, that several factors may have contributed, and that the tool used to measure it changes the size of the number by about thirty points.
What this means for Thai businesses weighing .co.th against .com
Thai companies face the same decision regularly, usually for the same reason described in this case: a single global domain, and not being read as a single-country business by advertising systems. The source says nothing about Thailand, and no Thai equivalent of this measurement has been published, so the transferable part is the mechanism rather than the number.
The mechanism is that a hostname accumulates history, and a move restarts some part of that clock while a redirect carries other parts across. A Thai site with a strong Google Discover or news footprint on .co.th is in the exposed group. A Thai site whose organic demand is evergreen product and service queries is not, in the same way. Either way, a migration plan is worth grading against the same checks a serious SEO audit would run before the switch rather than after it.
Two things are worth deciding before a migration date is booked. First, which query set actually pays the bills, because that determines which tool should be watched during the move. Second, whether the move can be staged in sections instead of overnight, which is what Google's guidance suggests for large sites and what Shehata argues for as well. A structured SEO programme for the Thai market should have both answers written down before anything is redirected.
The third question is scope discipline. Google's guidance advises against combining a domain move with a CMS change or a redesign, and in practice that is the most commonly ignored line in the whole document, because the domain move is usually the moment a business also wants a new site. Splitting a website redesign from the domain change into two separate releases costs time and removes the ambiguity about which change caused which result.
Frequently asked questions about this case
Which publisher was this?
The publisher is not named. Search Engine Journal reported that the post does not identify the site and does not share the underlying data, so the case cannot be verified independently and no one should try to guess the name.
Did the domain move definitely cause the drop?
The report does not establish that. Search Engine Journal noted the site was already losing visibility during several core updates and that internal technical problems likely contributed, so the data shows a collapse that followed the move rather than a proven cause.
Does this apply to Thai sites moving from .co.th to .com?
The source did not say anything about Thailand. The case describes one UK publisher measured on trending UK news queries, and no comparable Thai measurement has been published, so the reasoning transfers but the 98% figure does not.
Did the site use 301 redirects or a Change of Address?
The article does not say. It summarises what Google's guidance recommends, including permanent redirects and a Change of Address submission in Search Console, but it does not report what this publisher actually implemented.
Do I need to cancel a planned domain migration?
Nothing here says a domain move should be cancelled. It says the outcome is hard to predict, that measurement method changes the apparent size of the impact, and that staging the move in sections is what Google recommends for large sites.
The part worth keeping
One unnamed publisher, one monitoring service, and a figure that cannot be audited is thin ground for a rule. The durable takeaway is the measurement gap: 98% on trending news queries against roughly 60% to 70% on a fixed evergreen keyword list, on the same site, over the same period. Any migration report built only on evergreen keywords will understate what happened on fast-moving queries. The full write-up is at Search Engine Journal.
If a domain change is on the roadmap for a Thai site this year, the useful preparation is a baseline of the query sets that actually generate revenue, taken before the move and read on the same schedule afterwards. Relevant Audience can help build that baseline and pressure-test the migration plan against it.
