site extensions - use redirect or parking / landing pages ?

[scrawnybob]

hi all

ok so I've managed to waste a bit of time kidding myself that I have the time to build out .co.uk / .net extensions of main sites I have on .com's

realising that at best a 10-20 page site on a .co.uk of an established 4kingpoker.com url would make the name look weak and at worst it might even course a bit of "brand dilution" or confusion

I'm not sure which of the obvious options are best for .co.uk's .net's etc ...

simple redirect to the .com ?

or simple landing / parking page ?

there is a reason for this as I am also working on 4kingcasino.com / 4kingbingo.com etc so by keeping a landing page I could show the other options of sites and pad this out with descriptive copy etc to direct traffic possibily to multiple sites ??

Is there a bad SEO implications ?

also with the "brand" thing google is now talking about it's not like I have a big brand or anything but would I have been infact "diluting" the brand by building out .co.uk etc extensions of an existing .com site ???

cheers SB
