Exact match domain (EMD) names haven’t gone the way of the wind. Thousands of new extensions are being made available, but none will ever hold as much authority as the original dot-com extension.
LasVegas.com is one of the most expensive domain purchases in history. The domain name sold for a whopping $90 million in 2005, but would it have demanded such a price if it had been LasVegas.tv, LasVegas.net or some other non-dot-com extension?
The simple answer is: No.
Can you guess the buyer who paid $90 million? It was Vegas.com, and you will find both domains in the top of many Vegas-keyword-related search results today. Their strategy has paid off in tremendous ways.
(It should be noted when researching previous domain sales, these sales often incorporate other business transactions outside of the domain itself, such as the existing website.)
The exact match domain industry is healthier than ever before thanks to several factors: internet size and growth, the original dot-com extension, age, demand, search volume, branding, and the inherent SEO value that is unmatched with nearly all other marketing and branding investments.
