Question

Search Engine Optimization

There is a 4-character domain in the ru zone.
I bought it a year ago, now it is more than 370 days old.
Everything is fine, but there is a "-" in it, does this greatly affect the convenience of PR, input, search?
I personally ran into a search problem, when I enter my domain, (minus, dash, hyphen "I don’t even have much to say how to do it right") disappears and it turns out that any search engine is looking for the same domain, but 3 characters. If I start promoting it, will this problem disappear? Or will I always be confused?

Answer 1

90% of people can't even enter vk.com/ok.ru and are looking for "entrance page vtentacle".
The domain name in 99% does not matter at all, except for highlighting in the search results.
