Which domain zone to choose for an international project?

Question

Search Engine Optimization

What to choose if .com , .net , .org are busy?
I do not argue - you can come up with a long domain that would be available in the main zones.
I have reviewed many other options and now I am seriously considering a domain of the following form: ****.one (4 characters).
Are there any nuances of promoting such domains and will it be more difficult to promote it, comparing, for example, with .com?
Or is there not much difference and will depend on the quality of the content?
Please share your experience and knowledge in this area.

Answer 1

• For any sites for Runet, .ru is best.
  
• For informational sites - any, but not the national domain zone is better.
  
• For commercial sites promoted by geo-dependent queries, the corresponding national domain zone is better.
