To properly market your product or interest, you must be easy to find.
The first rule of findeability lies in the domain name.
Not only is a good name a 'high street position' but it can help in the actual search
Continuity in business is important, you can move your office
physically, but you can keep your domain name
for as long as you like. The payment
each year is the only cost .
Once secured you can reserve the name for as long as it suits you.
A good name, like a well positioned property is a good investment. Top
level domains are limited in number.
