Park the domain with a domain parking service. Since you may not have content to put on the site, a parking service puts up a dummy page with ads. When people visit and click on the ads, that's money for you. This method works best with popular keyword domains that get lots of traffic. In most cases, you will not have control over what ads appear on your domains.[5]
Domain flipping is the art of buying a good domain name at a wholesale price and successfully selling it at a resale price and making a profit. I’ve been helping clients flip domain names for over 10 years. The skills needed to be successful is some working capital, knowledge of domain valuations and a good information flow from a trustworthy domain broker who knows the landscape and can help source you the best deals.
Most domains traders, or resellers, buy hundreds of domain names. This way, the chances of hitting the jackpot are higher. But, this takes some up front money. You can start with a handful of names and work your way up. This is the best way to begin. You may also decide to purchase a name from another seller if you think that a name will be big enough.
Also with the domains, a name which can be cheap for one can be worth gold for the other. Permute the letters in your domain name and try contacting and eventually selling out to organizations that run under those names or contain the letters within. Companies would be keenly interested in buying out the domain names that matches the product's name. Hint : Look for companies on LinkedIn

If you don’t have a lot of money to invest in employees and you’d rather work on your domain portfolio by yourself, you’d need plenty of free time. Generally, mini sites with 5 to 10 pages of content can be built within 5 days, while authority sites with over 10 pages could take up to two weeks. This amount of time would depend on your writing skills and knowledge of SEO techniques.

Before you park any domain names, you must focus on finding hot keywords that buyers would be interested in. The best way to make sure you get a good return on your investment is to pick a domain name with acceptable traffic, somewhere around 10,000 searches a month. You can do this conveniently by using tools like Google Keyword Planner or Niche Finder Software.
Good point. Is the amount of work that went into getting a successful sale worth a $400 profit? Keep in mind, this is providing speculative numbers for the sake of debate. The real world hours invested in gaining position or page rank, and time a agency would sit on a domain before a sale would be much higher. We interviewed a few agencies that practiced this, not only those that supported our theory.
Hi guys, just a thought, you do not need to build traffic to the domain yourself, you can always buy expired domains, best to subscribe to a paid service like (so you are the first to know) or a free one, and in this way, you can get old domains that have traffic. You could use these domains for parking, getting advertising income or even to sell. I have noticed, that domains that were not hot in the past, can still be hot now, just use Google Trends to type in the keyword, and you will see its future projections. 
Adding domains to our Premium Listings on our website before you sell will give them more exposure to the community. We’ll offer an appraisal for your domain to give you an estimated selling price, and you can adjust that price at any time. We also offer a comprehensive breakdown of our commission rates for all premium listings, so you can easily understand the process.
Another point of concern is that many people feel that squatting or registering domains is unethical. This is because many web developers have a hard time finding relevant domain names for their projects since most of them have already been registered. Many corporate giants also frown upon the domain flipping industry because many domain names relevant to them are already registered.

As you can see just within expired domains they have over two million deleted .com domains. Now, this is obviously overwhelming if you’re trying to look for domains. So, you should use a few filters to make the search process a lot easier. To do that, click on the search filter button. Down here I like to click on the Only With A DMAS Entry because that just filters out sites that are really spammy. For sites that that have been in DMAS ever, it means that the site had to be of some quality.

Then the number is an HRL so it’ll be quite a bit different then you’ll see an expired domains because domain pop service is not very good compared to HREFs. Usually this shows about 20 percent of the total lengths. This shows more like 80. Okay? As you can see it has actually 162 referring domains which is quite a lot better than we saw in expired domains.
Buying and selling domain names is an exciting adventure that for some seems to conjure up images of finding hidden pirate treasure or guessing the winning combination on the next Powerball. Stories abound of domains that were purchased for $8 dollars 15 years ago being sold today for millions. Of course, that leads the more adventurous of us to wonder, “How can I do that?”
By default we show the following metrics - Age, Ahrefs Domain Rating, Moz Domain Authority, Moz Page Authority, Moz Trust, Majestic Seo Trust and Citation Flow, Alexa Rank, Moz Referring Domains, Majestic Seo Referring Domains, Open PageRank, SimilarWeb Rank, SEMrush Monthly Traffic and Domain Price. Apart from these there are around 40+ metrics that you can see by customizing columns

Hi thanks a lot for this. I appreciate your honesty. A lot of people need to hear this. I needed this to. When buying and flipping domains always ask yourself who would actually buy this domain, what they can do with this domain and how would you monetize this domain if you bought it. Always think of your customer and treat it as a business. I think you’ll avoid a great deal of dissapointment down the line. Thank you

What if we replace “bitcoin” with “ripple” in all these examples?…etc. You get the picture. There are a 100 of these on NameBio + the keywords we got from the Google Keyword Planner, that’s hundreds of potential high-value domains right there. The thing is, we’re only scratching the surface here. According to Wikipedia, there are over 1,300 cryptocurrencies online as of January 2018.
