Because of the penury of domain names, new extensions are created each year. However, regarding domain name values, .com is far ahead any other extension. A major part of the valuation of domain names comes from direct navigation. Domain names generate traffic per se, and this traffic has a value, comparable to the price to pay if one would want to purchase it with search engines. And regarding direct navigation, .com domains is the most powerful. Some country-codes domain names also receive a fair amount of direct navigation, and, to a lesser extent, .net domain names.

Historically, .net is the second extension and its price is generally between 10 % & 20 % of the the same .com domain. .net domains suit to almost any topic, but their value is higher when they are related to the internet. National country-codes such as .de, .co.uk, .fr, .it, etc. have different value according to the countries. But they are generally worth between 30% and 50% of the .com domain, provided that the language of the domain name is compatible with the country-code tld. The .de is a little different, as it is becoming also a generic extension, like .net, .org or .biz. This is already the 2nd most popular extension in the world, and most .de domains registered are now non-German domain names. The .org is worth between 10% & 20% of the .com, and a little more if the domain name is related to something non-commercial. .mobi, .fm & .tv have also a similar value, provided that they are respectively used for tv & radio programs and mobile phone users. The value of the .biz and .info can be worth up to 5% of the .com domain name, provided that they are respectively used for commercial activities & information purposes. The market for .pro, .ws, .cc, .bz, .vg & .to is much weaker and such domain names do not generally reach 1% of the value of the .com equivalent.
