I don't necessarily agree with some that dropped domains don't have value for SEO purposes but either way one thing you can do is to check out our tool for finding auction domain names (the tool has a database of domains available buy from GoDaddy and SEDO and also give additional SEO criteria to look up for the domains like backlinks, Compete data, CPC, Google stats, Alexa stats, etc. and there is also an option to schedule auction domain alerts so that you can be notified via email if a domain name meeting criteria you specify gets put up for sale) or you could use our tool fo domains dropping soon that shows all domains dropping in the next 5 days that way you can be ready to snap them up right away.
When you are selling a domain name, you don’t want to suffer because of failed transactions or being tricked by defaulters. Safeguard your monetary dealings; the best way to do this is to take the help of a secure domain transfer and escrow service. The escrow system is highly beneficial because a buyer has to deposit money at the trusted source prior to purchase, and the dealing between a buyer and a seller takes place through a secure domain transfer and escrow service. This makes the transaction safer for both parties with the involvement of a neutral third party.
Just like a property listing, except much simpler, domain marketplaces are basically massive lists of domain names that are up for sale. The process of using them is simple. Buy a domain and park it, then list your domain on the marketplace for a price you’re willing to let it go for. Once the domain is sold, the marketplace takes a cut and then passes on the remaining funds to you.
There are many places and ways you can purchase domain names.  You can purchase unregistered ones through sites like GoDaddy.  There are forums where people will gladly try to sell you their domain name (usually though the domains being sold in forums are either crap or the asking price is so high it does not allow you any room to flip the domain).  And then there is my favorite way of obtaining domain names, through an online auction at Namejet.  Let’s first talk about Namejet and then we’ll talk about how I personally ring the register by flipping domains.
Current Craze: When PokémonGo was HUGE last year, my domain flipping friends (Matt of Handshakin.com is one) were all about buying domains like PokeStopNearMe(.com) and other related domains associated with the PokémonGo craziness. It’s like the day trading of the domain world. You’re buying domains during the hype and hope to sell them for a higher price quickly before the hype fades.
So how do you develop that instinct? NameBio maintains a database of over 500,000 historical domain sales (as of writing this post). They have interesting filtering features by which you can narrow down domains by price range, date sold, keywords and more. Simply sifting through the listings on NameBio long enough will quickly develop your domain appraisal “instinct”.
