What you really want to do first is scroll down to where it says, referring pages for anchor phrases. All that is is the anchor text distribution to that site. As you can see here this looks like a very natural link profile. Brand name, a product that they had, no text, URL, shopping cart, wireless government. These are the keywords that were related to what that site was about. Okay?

Great post! I tried to repurpose an expired domain to build an authority site (your method 1) – but it doesn’t rank as it should. i checked the backlink profile via majestic and archive.org and it’s clean. also checked the metrics of the competition. with the amount of trust and link juice my expired domain has vs. the competition, it should be on page 1 for those keywords. is there something i’m missing here?

Namejet is a domain clearing house (at least that is my term for it).  What happens is that people let their domain names expire everyday.  Some people just don’t need their domain anymore, some people forget to renew it, some people die, I mean there can be hundreds of reasons why a domain will not be renewed.  What the domain registrars want to do is cash in on the domain that someone forgot to renew, so they offer that domain to Namejet to auction it to the general public.  Think of it like a storage unit, someone doesn’t make their payment and the storage company hires an auctioneer to come and auction the storage unit to the general public.  Namejet is doing this but for domain names.  The bid for each domain starts at $69.  What I LOVE about Namejet is the process…  they let you search through the domains that are coming up for auction 30 days in advance.  Whoever places a $69 bid on a domain will be entered into an auction when the 30 days runs out with everyone else who placed a bid.  If you are the only bidder than you get the domain for $69.  If there are 10 other bidders than there is a closed auction, meaning only you 10 guys can bid now against each other in a 3 day auction with the highest bidder taking the domain when the clock strikes zero.  I love this because let’s say there is a great domain and it flies under the radar.  If it goes to auction with only 3 or 5 or 7 bidders my chances of winning this domain at a very low price are great.  I’ve won domains for $100 which I was able to flip for $2,000.  I won a domain for $2,500 which I flipped within 4 months  for $7,500.  I won a domain for $1,000 which I’ve turned down $5,000 offers on because I think I can get $10,000 for it.  The key is to not overpay in order to leave yourself plenty of room to turn a profit when you flip the domain.
Domains that are indexed on Google and highly ranked are particularly attractive to traders. Other SEO aspects, such as backlink profiles or the search volume of the keywords in domain names, also play a significant role in calculating thevalue. Design can also positively affect the price of a domain. Short and succinct names that are easy to remember are especially advantageous. Endings are further factors that should be taken into account. Top-level domains (TLDs) such as .com or .org are by far the most sought-after endings.
Hey, the possibilities are endless when it comes to domain flipping so do not think that all profitable domain names are already taken. At this time, almost 90 million .COM domains have been registered, so people tend to think that there are not many good domains left. That is not true since you still have the opportunity to incorporate two or three word target keywords.

The third option is the one that's the most time consuming but also has its benefits. It's like having a successful restaurant and buying another restaurant and operating them simultaneously. They're not the exact same restaurant, but both are popular in their own right and make you money. The same goes for Option #3. You could update the content on the old domain and sell the same products that you're selling on your current site. If you can get both sites to rank alongside each other in the SERPs, you're increasing your conversion chances and sales potential.
I'm not against making money in any way, but $400 doesn't really seem worth the effort and coffee expense invested (I like the good stuff). This is a very basic example used to put the costs in perspective. Most SEO providers charge more than $50 per hour, and you get what you pay for. The above example of a final labor estimate is probably much higher, or if the domain is already ranking high and the owner wants to sell, so is the initial purchase price. Since this is often repeated many times over for multiple domains, it could get time consuming, and expensive.
What type of business are you considering of building something on using the domain name?Is it something you believe in and willing to put your all, how much can the monetize with the website, etc..Ask yourself much questions before proceeding to finally selling it.Also, it doesn’t matter if a different company is using a different extension.It means you have upper hand to get their traffic if you build something using the .com.Good luck

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:
This is a little bit on the grey hat/black hat side of the spectrum. But the fact is building a blog network with expired domains flat out works. The only issue is getting those cream of the crop domains without going broke. This video will walk you through tested strategies and techniques you can use to find powerful, yet affordable, expired domains.
Here's a test I have in process.  I bought an old $5 closeout domain from Godaddy TDname expired auction.  I put a quick minisite up and linked to it with a crazy anchor text phrase.  The domain is ranking for that crazy term now.  It's gone through one pagerank update and I'm waiting for a second to come.  Then I'll redirect the domain to another minisite.  I suspect the second site won't rank for the anhor text, but we'll see.  
Buying and selling Domains is a tricky industry. You easily get addicted to it without really knowing what it's all about. Unfortunately I learnt a lot of the answers on here after losing 6k on useless domains. It is a constantly changing industry but the subject that keeps coming up is TRAFFIC. Organic type in Traffic. Those premium domains are long gone and you need to spend big bucks to acquire them on secondary markets such as Domain Auctions, Expired Domain Names, and Available Aftermarket Domain Names for Sale but if you keep up to date with future trends then you can spend less on hand registered names. You really need to think outside the box and spend a lot of your time reading industry leading blogs like business insider, network as much as you can and have a specific niche before jumping into other trends that you don't quite understand. There's so many ways of selling. Don't try and sell to other people who are trading domains aka domainers instead look for an enduser on Google by typing the name you own and if there's advertisers then you have yourself some leads or use tools such as Free Domain Appraisal and Domain Productivity Tools. A buyer can be convinced to buy if you have the numbers to prove how much that domain would be worth to them. Find out how much they spend on advertising per month then make comparisons with the number of direct type in traffic they get from your domain that you selling. If you can prove these numbers then it's easier to sell otherwise you better off holding on to it, maybe develop it the way Trump has developed his name until someone interested gets in touch. There's so many platforms where you can list the domain such as The world's leading domain marketplace , Park Domains - Afternic -DomainNameSales.com etc . Please NOTE  I am not promoting any of these services but I have used them before and have had some success. Probably should have signed up for their  affiliate programs but haven't had a chance before this question came up. There's so many other metrics involved  so research as much as you can, don't spend a day without reading about the subject and go in at least knowing what you are doing. My two cents.
Most of the website owners interested in an expired domain that has existing traffic, backlink and good SEO metrics. This kind of domain more likely gets buyer easily since it has a plus value for search engine optimization purpose. You can find high-quality expired domains that have SEO metrics by using BuycomDomain - The Expired Domain Search Tool for free, as seen in the picture below.
What if we replace “bitcoin” with “ripple” in all these examples? SellRipple.com? RippleGiftCards.com? Ripple.network? Ripple.us…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.
