I've been hearing a lot of similar report in recent days - it sounds like a bug in Google's filtering for geo-location. We can certainly hope that's the case, because it doesn't make much sense in the cases I've seen.
Does the site have links from sites hosted in India?
Interesting question Martinibuster.
I have a site that has experienced an expected plummet in the SERPS subsequent to a major overhaul. Was prepared for that, and will wait it out with some confidence that it will ultimately exceed its previous performance.
Interestingly though, it is experiencing a significant surge in international traffic, much of which is comming from Google (e.g. www.google.co.za, www.google.lt, www.google.it, www.google.ie, www.google.ca, etc.). This is far more interntional traffic - specifically international traffic from G referrals, than the site ever experienced before.
The site in question does not have a significant number of foreign links, and the server it resides on is housed in Utah.
I had thought it was a quirk related to the overhaul/redesign until I read the OP's post.
If G.ie is anything to go by, the amount of Irish pages in the "web search" results for generic terms has dropped quite significantly allowing "foreign" pages to feature more prominently.
Might explain WBFs' situation though probably not the OPs....
Don't think it's just legal sites :
My main site is also affected. It targets folks in the US but as of 3 weeks ago, it has fallen to #400+ for a search phrase (it used to rank #3) if you filter for US serps. On all other Datacenters, it still remains at top 5.
I had missed that thread.
It's been this way with several sites here, in that there is an exponential increase in traffic from across the pond.
Many of these sites don't sell or otherwise conduct business outside of the U.S.A./Canada. Though their geo is North America, their listings are 50/100 pages deep in the search for their terms.
A mate over in Brookvale, however, says of late, that many of these same sites are showing tops for their terms in Sydney.
Yes the site has links from India also as well as from UK sites.
Interestingly when I am running rank reports using US google datacenters it shows resukts on top but if you check the same datacenter in US site is appearing on page 5 or 6
