If you know how to get websites to page one, why are you not marketing that fact to potential clients and consumers or would-be domain purchasers? Trying to get a keyword driven domain to rank high and sell it off for a profit isn't a good investment, either time wise or for the long-term success of your company. Instead, use sites that you have already ranked high as an example of how awesome you are and sign them up for a monthly fee, rather than trying to sell them a "make money now" domain.
Unfortunately, you probably won't like my tips. You need to look for quality domains at a good price and be willing to hold on to them to get your money back or know when you've invested wrong and get rid of them. Quality is in the eye of the holder, and believe me, I've looked at plenty of domain portfolios that the owner just knew were million dollar domains but in my opinion, they'd be hard pressed to get anyone to take them off their hands for just the registration costs. You have to figure that most of the best .com domains were registered in the 90's, and those are the ones you typically see the 6-7+ figure sale prices on. I'm not saying there isn't money to be made because there is. But it does take time, research and money, and maybe in some cases a little bit of luck. If you're thinking of getting into the industry, I recommend digging into the resources provided by Michael Cyger on http://domainsherpa.com and from there, moving to some of the other big blogs such as TheDomains.com or
One of the easiest ways to make money online is by buying something for a low price and selling it for a higher price. It is even better when you don’t need to pickup or ship a product. Today I’m going to talk about how to make money online by flipping domain names and how I personally have made tens of thousands of dollars in the past year doing this.
I have an interesting twist on how I have done it in the past. I will buy a domain and use it as a development domain for blog posts and things of that nature. Then over time it will gain DA and PR. Then I will sell it off and buy another development domain and start the process over. Not quite the process you mentioned, but it works. People will link to the development site to show things off as well sometimes, so that helps.
They see a domain’s price tag and they can instantly tell whether it’s under or overvalued. This is probably the most important skill one should have in this industry. Neil Patel has an interesting related quote: “The most important thing to remember when buying sites is that you always make money on the buy, never the sell.” In order to successfully do this, you must be able to spot undervalued domains. This is what will ultimately translate for you into a handsome profit margin when you get the opportunity to resell the domain for its “real value”.
