Features of choosing a domain registrar

Or is there no difference what to choose?

There are differences, of course.

GoDaddy is well known registrar, the biggest out there. They provide great marketplace solutions, and their domain management interface is quiet straightforward, easy to use.. However, you pay premium for that. The pricing is quiet extreme compared to competition. As long as you don't have Domain Discount Club subscription, it doesn't make sense to register and and manage higher volume there.

Personally, I prefer Dynadot with their much more affordable pricing policy. You can also try Namecheap, Name.com, whatever that fit's your needs. Every big(ger) player on the market offers high level of service. At least from my personal experience.

Yes, you are right. But I would not choose completely unverified domain registrars. Because it often happens like this: you register a domain at a low price, and then during the renewal it turns out that the prices will be too high. I have chosen the Pananames registrar 2 years ago. Everything is clear with prices here. Moreover, the prices for the renewal are scheduled for many years ahead. I also use hosting offered by the registrar. The prices are quite adequate. Everything is fair and there are no unexpected price increases.

Unexpected price increases also come from Verisign price increases, which is something registrar don't have under control...

Anyway, I am talking about well-known, big registrars.

Therefore, I want to try the services of registrars, where there are more adequate prices for registration and renewal.

Nevertheless, I advise you to try https://pananames.com/ and check their conditions. I like this recorder.
