Is adding uk in domain name will cause me trouble?

Is adding uk in domain name will cause trouble if i am monetizing amazon? examples: petuk.com or exampleuk.com. I am confused if it is. Thanks in advance for your answers

No it shouldn't cause any problems. If you are targetting the UK make sure to use the UK amazon associates account (I think you have to sign up seprately for US/UK).

Also if you are targetting the UK... why not just buy a .co.uk instead? it'll help with your search engine rankings if you are wanting to target UK people

i will go for .com the reasons are of course for ease of use, it's easier to tell people, easier to type, easier to remember.and also You won't lose much UK traffic if you host the site on a UK server.
