Theres an Overture page for each country ie
UK
http://inventory.uk.overture.com/d/s...ry/suggestion/
USA
http://inventory.overture.com/d/sear...ry/suggestion/
DE
http://inventory.de.overture.com/d/s...ry/suggestion/
If you goto the UK one and type mickeymouse.co.uk and mickeymouse.com you get 23 and 54.
That roughly means 23 ppl type in mickeymouse.co.uk and 54 ppl type in mickeymouse.com per day in the UK searches of Overture and their partner sites ie Yahoo etc.
If you try the same search in other overture countries you will get different results...
but always search with the EXT ie xxxx.co.uk xxxx.com.
