A domain is the word under which a web page is hidden, e.g. the domain is seoski.pl. It can be said to be a very important part of an online identity. Each domain is unique and only one with such a name can be created. In fact, a lot depends on the domain, as it should be short and catchy so that it is easy to remember. Of course, this does not apply if the domain is the name of a company or the proper name of some product. It must not be forgotten that the domain name also influences the positioning our website.
