I'm in the UK. I have a .com site. Until recently (sometime in the last 3 weeks), the site was ranking well for both a default search, and also a 'pages from the UK' option search. The rankings were very similar for both options - even slightly better for the 'pages from the uk' option.
Now, ranking for all but a couple of phrases for the 'pages from the UK' option have either dropped to around the 5th or 6th page, or disappeared completely. The homepage has also gone from the 'pages from the UK' SERPS.
A site:domainname search lists the pages in the site ok when performed in the default search, but lists all pages APART from the homepage when done with the 'pages from the UK' option. Also, a search for the domain name shows the homepage in the #1 slot in a default search, but a search for the domain name using the 'pages from the UK' option shows the same list, but no homepage anywhere.
When the homepage goes, of course, it's probably a penalty of some sort.
The site is hosted in the UK on a shared IP, physically located in the UK. I have located other .coms on the same IP and their homepages show up fine when the domain name is searched for using the 'pages from the UK' option.
Has anybody experienced homepages going missing or penalties which are only triggered with a GEO option?
Any ideas greatly appreciated - this is really confusing me.
