Could anyone explain this "strange" behaviour for me ?
a)
For a 2 word phrase I'm #1 in Google when searching from my home country.
b)
When doing a spesific search in my country I'm still #1.
c)
When doing a singelword search I'm nowhere to be found, even that I've been at top 5 for years.
d)
When I search spesific in my country or in my language by using singelword I'm #1 again.
All those companies that are above me when doing search c) is behind me in d.

Is it less links from other countries that could make this drop in search c ?
I have both singelword and 2 word phrases on my site, but in the title I have 2 word phrase only.
Meta tags is with 1 and 2 word phrases.
