How to choose a domain?

Question

Domain Name System

Hello! I'm going to register a domain in the RU zone. Immediately there were 4 questions)))
1 - Does it affect the issuance if there is a similar domain, older and promoted, though in a different region. Will mine get confused with him or is it somehow lost there? The difference will be just one letter..
2 - Does the key in the domain affect the issuance?
3 - On which site is it better to register a domain, so that there would be a wordpress right away
4 - Does it affect the issuance if the domain is in Cyrillic like site.rus
Thank you all! and sorry if this is a stupid question

Answer 1

1. does not affect. a similar domain is another domain, it has nothing to do with yours?
2. What is the key in question?
4. in theory, no.

Answer 2

1) Do not choose such a domain. Your users, having made a mistake in the name, can get to someone else's site, not yours.
2) Does not affect.
4) Don't pick on the krill. He has a lot of problems.
