Finally, if you were to manually check for drop domains, you have to jump through many hoops. It's a very labor intensive and often confusing process. When you see that a domain name is available, you shouldn’t just stop there. You should also pay attention to how many backlinks it had, how niche-specific the domain is, what kind of websites link to it, did it get signals from social media, and other indicators of quality. If you were to try to look for drop domains manually, it can be a very, very intimidating process. Thankfully, there is an easier solution.
I had two domains, a .com and .net with godaddy. I’m beyond their redemption period ($80 fee), but they said it should be released back to the public domain soon and I may be able to get it back. Before I knew this, I paid $12.99 plus ican fees for the .com thinking it was available as the rep told me she was able to add it their cart, and I paid a $24.95 fee for back ordering my .net domain. Shortly thereafter, I received an email from godaddy saying:

Although I have one query (this answer does answer it, but I have a doubt)… I just bought a domain which had the creation date as 2010 but after acquisition upon checking I found that it has been reset to 2014. So, from what I understand from your article, this could not be undone anyways because this particular domain’s status said as ‘Expired’ and I got it for under $10 from godaddy?
However, Pool uses what some have called a “two-phase” auction system. This means that once you win your original backorder, Pool will then move you into the auction phase where you compete with other bidders for the domain. Pool doesn’t reveal how many bidders there are or what they’re bidding, so you have to offer the highest price you’re willing to if you want to get that dream domain.
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.
If you buy a dropped domain from Snap or Namejet, the backlinks seem to be worthless for SEO.  They are valuable for traffic if it's targeted to your site.  Go ahead and 301 redirect into your site because it's the traffic from the back links that is worth something.  I use the Google URL builder to redirect these names so you can see the domain the traffic is coming from.

Next, some of these expired domain names have ranked in high authority sites that are ranked or had ranked themselves. Besides, some of these domain names are worth a fortune. For example, domain names sell for about ten to twenty dollars each. However, those that are the most sought after can go for over $ 2500 a month because they have lots of traffic back links or rankings.The last advantage is that you don’t have to spend much to find expired domains.

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.
