.com and .co.uk search?

I've noticed with my site if I use google.com and search the 'sitename' my site is top of the list, but if I use google.co.uk and search my 'sitename', I can't find my self in the list.

It's the same with the msn search, how do I get my site to appear when using google.co.uk or msn.co.uk?

My site is a .com but I've seen other sites in google.co.uk which are .com's.

Any ideas? Plus how would I fix it?

The service provider that hosts your web space, where is it located? If you are running from servers in the US let me know, because I beleave the geographical location of the IP address behind your site has a part to play.

Let me know because I have a UK IP address and I get good coverage in the .co.uk search engines, but not on .com search engines.

I have both types of site http://www.arcadegames.co.uk/, http://www.jadab.com/ but get best results in uk. And the time of day for visitors to my sites seem to support searched occuring in the UK. http://www.domainhub.co.uk/stats/2005/04/W/gip.shtml
