To ensure in Bing, that one of my UK based .com sites gets indexed as a UK site I added the following Meta Data:
meta http-equiv="content-language" content="en-gb"
Excellent I thought, not so.
On checking keyword ranking in Bing SERP I find that for some pages the site ranks highly in 'show all', and not at all in 'Only from the United Kingdom', and other pages vice versa.
This problem has been on going with MSN for some time now and really it's about time they sorted it out, just like Google has in its Webmaster Tools.
