There are many different ways to make money in the Domain Name game, but rather than skim over half a dozen of them at no great depth, Buffet takes a detailed look at Domain Flipping, one of the simplist and most effective ways to make money online. He lays out a step by step plan to guide you through the process, as well as a list of free resources that are invaluable.

Buying a website is a risky job especially if the investment is big. My first experience was a big fail. So after some time spent on Flippa I found out about a site called Safe Site Buying which I heard that was created by super sellers from flippa and got a coupon code "flippa50" which was supposed to give me a huge 50% discount. This deal looked pretty good to me so I tried it. They provided me with a full report, 20 pages long and with their own subjective opinion. They were very helpful. When you want to spend more than $2-3000 on a website this service is a must if you ask me.

Use escrow services for direct sales. When you are dealing directly with the buyer, make sure that any money that is transferred goes through an escrow service. This will ensure that all checks clear and that you aren't left with a bounced check and no domain. Escrow services may add a few days to a sale and cost you a percentage, but they can save you a lot of heartache.
If you are feeling ambitious, you can link each of your domain names to its matching “buy it now” purchase page at one of the marketplaces. Another more sophisticated option would be to “park” your domain with one of the leading domain parking companies, such as DomainSponsor or SmartName and enable their built-in “for sale” message and contact mechanisms.
If you’re serious about domain flipping, one of the best strategies is to buy expiring domains that auctioned on the market such as GoDaddy Auctions. Make sure you pick domain names that have good traffic, backlinks and SEO metrics, or domains with the generic niche. Expiring domains with a potential for profit can be found using, this is a free website/tool that helps you sort through the domains by different metrics (age, traffic, backlinks, domain authority etc).
In the past, expired domains were used as part of black hat SEO in order to generate backlink sources quickly and easily, and this practice is still used somewhat today. Getting links in this way is not a recommendable practice. All relevant search engines work nowadays with highly complex ranking algorithms, which can no longer be outsmarted by these link networks.
There’s an important distinction to make here between domain flipping and website flipping. The latter mainly refers to buying and selling full websites. By full websites, I mean websites that actually have content and more often than not have traffic and revenue. When buying and selling websites, the domain name matters less as the main value there is the content, traffic, revenue, history/reputation, sustainability and growth opportunities. The same can’t be said for domain names where you’re just selling “the name” and hence it’s all that really matters.
