This post is dedicated to one of my favourite niches the 5 letter domain names! Available 3 letter domain names are looong gone those are selling for minimum 5000$ today most often for much more. The last available 4 letter domain name was sold in November 2007 as I recall and those types of domains are selling for around 30$ even names like xwyq.com are easily sold (even though the economic crisis is hitting this market hard and prices are actually falling right now). Which market do you think will be the next buy-out market? If you guessed 5 letter domains you guessed wrong :). There are about 12 million different combinations of LLLLL .coms with nearly 90% of them still unregistered it might take a while before they are all bought out, especially if you consider the amount of junk names within this group STATS. The 4 letter niche had the advantage that it could be used as acronyms, names like wabc.com could be an acronym for Water and Beer Company, but 5 letter names are mostly too long to be used that way. Therefore a five letter domain name needs to be pronounceable in order to stand out, it needs to sound good and be brandable. Then why on earth are you investing in those names then? I still think the value of lllll.coms will increase, as more and more domains are bought and all the generic ones are gone people need to find short brandable names for their businesses, also 5 letter domains are very brandable and easy to remember. With the rise of Web 2.0 we saw a huge boom in personal websites, blogs, social networking activity and online niche stores, those types of sites need brandable names which people remember. It is also more and more common for big Internet based companies to use a 5 letter domain, sites like Joost, Skype and Kazaa.com comes into my mind. There is only one .com version of every name and I think that those good pronounceable 5 letter domain names available to register are soon to be a thing of the past. The Internet is only getting bigger and the number of good sounding 5 letter names are limited, my guess would be that 90% of them are already registered today.
