If you are pursuing option 1, then you will want to use an automated service for the reasons mentioned in the article. Follow the process in the article to see which registrar the domain name is located at. If it’s at a Auction House like GoDaddy, NameJet or SnapNames, I believe they publicly share if there is a backorder on a domain name but not who placed that backorder. (Any interest in a domain name may be enough for someone else to place a backorder, thereby driving interest in the domain name that may be visible to the registrant.) So if the domain is at a registrar partnered with one of these companies, then you’ll have to monitor it manually (via calendar entries based on the whois expiration data) to maintain your distance.
That’s it for deleted domains which you can just pick up by heading over to your favorite registrar and registering it right away as long as it says, free and green here. If it says registered it’s obviously taken. This is obviously a cheap way to get some great links because let’s say, you know, this site we saw is not bad. It doesn’t have page rank, but that could be just because there was no content on the site. If it has a solid link profile, you can be sure that the page rank will come back and you can pick it up for about $10.
I wish I could tell you that expired domains are some sort of magic bullet solution to all your traffic problems and headaches. Unfortunately, if I were to say that to you, I would be lying. There are drawbacks. Just like with anything else in life, there are advantages and disadvantages. The problems with expired domains is that they are often hard to find on your own. You can take wild guesses and waste a lot of time, effort and energy, and end up with nothing. Also, if you were to try to scope out drop domains by trying to find them in the most common way, which is to use a drop domain exchange, expect to pay a lot of money. Why? Because of heavy competition. Keep in mind that you’re not the only person who knows that dropped domains can bring a lot of traffic to the table. There are many other online marketers out there that realize drop domains' traffic value.
The better quality links (From Google, Wikipedia) that a website has the higher will be its domain authority. New websites start with a ranking of one, and as the number of links increase the domain authority rises. For example, a sports website that has links to sports newspapers and sports reporting sites will have a higher domain authority than a sports website that only has links to other sports and sports blogging sites.
Surely if you purchase a domain (domain1.com) and redirect it to your existing domain (domain2.com) you expect to loose all ranking for domain1.com. If 301's are used then the objective is simply to pass on authority, not dominate the search results with 2 domains. If you want to keep domain2.com in the index then you would take Rebecca's option 2 or 3.
 On April 11, 2016, SnapNames (owned by Web.com) and NameJet (partnership between Web.com and Rightside) combined resources on pending delete/dropping domains to better compete with other drop catching services. Going forward, backorders placed on either platform for pending delete names will go into a common backorder pool and will be fulfilled either by NameJet or SnapNames depending on which platform the backorder was placed. Pending delete names that have multiple backorders will be placed in a common private auction accessible to bidders from both platforms to participate in the live auction. Minimum bid increments and proxy bidding rules for NameJet will be modified to match those of SnapNames. Registrar expiry, and direct lister inventory will not be affected by this integration.
Some jerk stole my .com domain name after I had owned it for 10 years and accidentally let it expire, and he’s trying to extort lots of money from me for its return. On the site where it says who owns it, it says “Domain Status: clientTransferProhibited”. What does that mean? The domain expires on September 26. He’ll probably automatically renew it, like he has for the past couple of years. But in case it becomes available, I want to grab it. I’m the only person in the world with my name, and I posted at a blog for 10 years with that domain name. So I’m really upset I don’t have my own name anymore.
The biggest advantage of using expired domain names to earn cash online is that they belonged to a website that had already establish, registered with several search engines companies and has existing backlinks and traffic. In general, by making use of expired domain names you tap into the resources that were created by someone else to get rich within a short time unlike when you do all the dirty work to get your website recognized immediately.
