Domain name sellers are advised to use to list their domain name. The real advantage with is the mandatory escrow service that comes with every transaction. The site charges the seller a commission of 15% per transaction or USD 50, whichever is higher, for domain names featured on the site.

So, what I like to do is also choose DMAS listed entry. No fake or no unsure page rank. Click the apply filter button and this will show us a much better group of websites, including a lot of high page rank websites. That’s one great thing about Go Daddy Auctions that you don’t have to guess about what the rank will be which is not the case with a lot of deleted domains which, because they were deindexed they didn’t have any content, they didn’t have any hosting, they don’t have any page rank. So, you have to make an estimation.

Many non-savvy internet users may not even be aware of the existence of other extensions. That said, because there are many new extensions popping up every now and then, you can often find amazing one word and 3-letter domain names with these new extensions that are otherwise almost impossible to find unregistered in the .com world. Additionally, these new extensions are becoming more and more familiar to users every day, hence it's almost certain that their value will continue to increase as time passes and wider adoption manifests. 

Length: This is pretty self-explanatory. Generally the shorter the domain name, the more valuable it is. This difference in value decreases exponentially as the name gets longer, though. For instance, the difference in price between 3 and 4 letter domains are significant, while the price difference between a 7 and 8 letter domain would usually be much less significant.
