Since starting SEO back in 2009, it has become very difficult to rank brand new domains. Unless you are building a brand, it's highly recommended that you start every new money site with an expired domain. Additionally, if you're building a PBN, you should only consider using expired domains. The problem is good domains start at $50 a piece, and anyone charging less is either full of sh*t or selling garbage domains, and I mean that. If it sounds too good to be true, it probably is. DomCop has a great offer that all of you buying expired domains should consider. For the price of a couple domain names, you can use DomCop for a month, snag some excellent domain names, which would otherwise cost you thousands of dollars. If you're considering expired domain software and don't have the knowledge to program your own crawler, I'd lean towards DomCop.
The domain name industry is quite similar to the real estate industry in a lot of aspects. There are end users, brokers, consultants and domain flippers or “domainers”. Domain flipping works similarly to buying a house, renovating it (or even sometimes just sitting on it) and then selling it again at a higher price point. The gist of it is: you’re purchasing a domain name and betting it’s worth (or will be worth) more than you paid for it. If you’re right, you get a nice paycheck and move on. Those who make a living out of this just rinse, repeat, and scale.
