When selecting a site name, users are faced with a specific concept — the domain level. Some say that the third-level names are bad, others consider alternative options irrelevant.

How to correctly determine the domain level, and which one the search engines do not like? Let’s analyze the key points.

This type is also called a domain zone and it is not available for purchase. It is registered by the competent body (ICANN) and is accessible for public usage. New zones are constantly appearing, so the question may arise, for instance, what is .edu domain?

The .edu provides a great opportunity to get an excellent domain name and increase webpage traffic for universities. To register in the .edu zone, one needs to contact the responsible zone administrator — Educause, — and provide all the necessary documents about the accreditation of the educational institution.

Additionally, first-level domain zones are provided to the countries:

  • .us — USA;
  • .uk — Great Britain;
  • .ca — Canada, etc.

Top-levels also indicate the type of organization that uses it:

  • .aero — for air transportation;
  • .jobs — for recruitment sites;
  • .travel — for travel companies, etc.
