I'm having thes ame issue and I think it's more complex than the answers seem to indicate.

Of course, results on "pages from the UK" should differ in that US based pages should rank less highly.

But in my case, the difference isn't really in the US sites.

What happens is that my site is #3 on the "Pages from the UK" version. When I select the "the web" version, my page is not in the top 1000 pages. But the pages that replace mine are not US based ones. The "Pages from the UK" and "the web" search list are pretty much the same sites - almost all are .co.uk sites. What happens is that they all jump up a couple of ranks and mine and one other one in the top 10 disappear completely.

So it's not a minor difference, or the introduction of .com sites. Somehow my site and 1 other are being ranked completely differently on the "the web" vs the "pages from the UK" list.

My site is new and I've been doing a lot of backlinking, so maybe the "the web" version has "sandboxing" and the "from the UK" doesn't.

FYI the search is for "business consultants manchester" on google UK and I'm the Lighthouse page.
