The more memorable the domain name the more it is worth. If a domain is easy to spell, is short, is easy to pronounce, is potentially brandable and ends in .com then you are looking at a premium domain name like QuaSeo.com.
Look past the broad value spectrum and consider how a €1,888 domain name's cost compares to the value proposition of traditional media.
The real question is not how much a domain name costs but how much value the right domain name can bring to your business.
Take a look at your marketing budget and see what €1,888 buys you. Not a whole lot - well, you can own QuaSeo.com forever for that cost.
