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.
At the end of the day, the owner of this domain name let it expire and didn’t renew it. So while there may be many legit reasons as to why they might’ve done that, one of the not-very-legit reasons could be that the domain is “dead” in some way or another. In other words, it’s no longer useful for the original owner because of a penalty or otherwise. If so, it's unlikely it'll be of any use for you as well.
To find popular phrases I opened up the Google Keyword Planner. This free tool by Google, allows you to find out how often a word or phrase is searched in Google. A phrase like “Yoga Mat’ has on average, about 10K – 100k monthly searches. That’s A LOT. However a more niche phrase like “Good Yoga Mats” only has 100 – 1K monthly searches. These seem similar, but I wanted to focus on the exact popular phrase that people are searching for.
Great article on what to look for when buying expired domains! I’ve looked at the domain and page authority of expired domains but haven’t checked if they are blocked by Google like you’ve listed. I haven’t pulled the trigger yet to purchase one (probably good that I didn’t since I didn’t do all my homework) but this will make it easier to finally go. Thanks for the great info!

Mr. Dabir as far as my knowledge is concerned such media oriented names are of premium category and may seek higher value. I was acquainted with discussions going on regarding primarily hindi language entertainment platform called http://hindi.media and the dealing was of higher end hence expect it to be in several thousands bucks. Any inferior expectation may beget only disappointment.

You can easily find domains using the best metrics available from Ahrefs, Moz, Majestic, SEMRush, Similar Web, SEMrush, Domain Scope and Social Networks. We buy only the best, the latest, and, the most comprehensive industry wide metrics so you have the maximum amount of information to make a decision. No other tool gives you access to 90+ metrics.

But in general, the best and easy way to sell a domain is to go with a marketplace. There is many popular marketplace dedicated to selling domains including Flippa and SellDom to sell your domain (full disclosure, I’m working on SellDom). The advantage is to leverage the popularity of that kinds of services in hope that someone will find your domain and buy/make an offer.
If you buy keyword specific domains, you're really buying the type in traffic.  I use the URL builder and redirect through that URL so you can see how much traffic your getting from the keyword domain.  There seems to be no rythme or reason to what keyword domains deliver traffic and what don't.  By tracking traffic with the Google URL builder you get a feel for what names are giving you traffic and which are not. ie. the plural, the singular, two words, three words, the possessive, etc.
Expired domains are domains that have been registered by individuals, businesses, or organizations, but aren’t renewed after the contract ends, or are deliberately terminated. That means that they available for re-registration. There are many reasons why someone would choose to abandon a domain; one reason could be that the web project failed, or that a domain portfolio went into liquidization. Domains can also end up becoming free due to the owner receiving warnings for possible trademark infringement. Re-registering can also result in legal consequences.

Also note the Expired Domain Plugin is a lifetime “per user” license, so if you have multiple ScrapeBox licenses registered to the one email address purchasing the Expired Domain once will activate the plugin for all your ScrapeBox licenses with the same email for life. The plugin is a one-time payment and is not a monthly or yearly subscription, all updates are free.
Thanks for the great review on domain flipping. I could definitely see myself getting into domain flipping down the road. I constantly find myself thinking of domains that are probably worth buying. But the way you have presented and analyzed which keywords get the most page views makes it more like long term investing. I also never considered trying to market the domain names or that Adsense money could be generated. Thanks for sharing and good luck with your domains!
Very good article and overview explanation. However I would not recommend buying names with bitcoin, ripple, etc in them. Not only will it be oversaturated those names are brands and can / will be trademarked and you can still be hit with a UDRP. Only register generic names like buycrypto.com, buyingcryptocurrency.com, theblockchain.com, etc. There are tons of opportunities and no need to infringe on a brand name.

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 BuycomDomain.com, this is a free website/tool that helps you sort through the domains by different metrics (age, traffic, backlinks, domain authority etc).

There is NO accurate way to predict the sale of digital assets – if someone wants it, they’ll buy it. For example, those wasting their money on useless .com’s (LLLL’s that have no rhyme or reason) will spend 3x more time and money optimizing their useless name as someone that buys ANY keyword loaded domain (regardless if a TLD or new one). But these individuals who are spending thousands on domains will eventually get stuck with these domains in favor of (you guessed it) the oft forgotten yet highly useful 1-3 keyword domains. Why? Study Google’s algorithm as I have for over a decade, and you’ll figure it out.
You can turn then into content sites, set up an actual website, or try to sell that site elsewhere. You may even luck out by selling a site that's up and running and full of great content already. In this case, you can ask a higher price. Or, you can set up a shared hosting or direct hosting website. Shared hosting and direct hosting websites can be profitable too.
You can add it as part of a private blog network or you can 301 redirect an expired domain to your site to bring some trust and authority to your site. Now, in my experience, the best place to look for expired domains is this free website called expireddomains.net. So, you just have to head over there, make a free account and this is the page that you’ll see when you log in.

Unfortunately, most domain names take at least a couple of months to sell, especially without an attached website. Thus, there is no need to become discouraged if your domain name does not sell immediately. Most people make the mistake of quitting their domain speculation endeavor after waiting for several months to sell without success. In reality, domain name squatting can be just as profitable, and it is a valid form of long term investing.
Link popularity: the link popularity is a parameter that is used to quantitatively evaluate incoming links to a website. This is measured depending on the number of links to a domain according to the mantra 'the more incoming links, the more important the site'. Link popularity is generally determined by the PageRank algorithm. The PageRank only plays a minor role in determining the domain’s relevance.
I have a question regarding a certain keyword though generic but it is trademarked and the trademark owner asked me to remove the parking page, is there a way i can offer my domain name to the company? What is the best approach in selling the domain to him without hard selling it and giving a reasonable price. I will be giving 10% commision to any domainer-mate that can help me pull the sale off.

If domains are real estate, then the same rules of real estate should apply. In real estate, taxes are based on the value of the property. So, a person asking $10,000 for a domain shouldn't be paying the standard $15-30 renewal fee as a person asking $200. The renewal fee should be based on the domain's value. Domainers want to claim it's like real estate without applying the most fundamental rules of real estate.
So the keyword planner came up with 332 keywords related to ripple, most of which can be used to inspire a domain registration related to ripple. Let’s go ahead and get some more ideas. We already know that ripple is another cryptocurrency. Let’s head to NameBio and explore crypto-related domain sales. We’ll use bitcoin for this experiment. I’ll type in “bitcoin” in NameBio search, select “show all” and then sort by price by clicking on the price column. Here’s what it looks like:
