The easiest and least time consuming option is to 301 redirect the old domain to your existing site. This tactic obviously works best if both sites are in the same sector and are targeting the same keywords; otherwise, if you have a pet supply site and you buy an old Texas Hold 'Em poker site, a redirect probably might raise some eyebrows among the search engines. If, however, your site is brandnamepets.com and you buy onlinepetsupply.com and 301 redirect the domain over, you're inheriting a lot of topical and appropriate links.
Ultimately, I was left with a semi-automated process of scraping sites and running an intricate series of processes to come up with a list of expired domains that I then had to evaluate by hand. This meant I had Majestic and Moz open to check the backlink anchor text and Archive.org to check for obvious spam for every single possible domain. The process was excruciatingly slow and tedious, but absolutely necessary to find domains that would be suitable for building out.

What about option #4 - Redirect your existing domain to the old domain? I bought an old domain that is 100% relevant to my current domain but currently has with very little content. It did have more content fours years ago. The old domain is 13 years old, pr=3, while my current is 7 months old pr=1 and a decent amount of content. The old domain I purchased was not expired though and I do not know if this makes a difference. What are the pros and cons of option #4? Am I correct to think that option #1 would result in no benefit from the old domain's age value and if so why is it not listed as a con, a MAJOR one. Its hard to believe that a 301 using option 1 would give my existing domain 13 years credit but I'll take it if it does.
Backlinks – These are basically anchor links present on external websites that take the visitor back to a domain. The higher the number and authority of backlinks, the higher the authority of a domain. For example, if a domain has a backlink from Forbes, TechCrunch or BBC, it’ll gain a lot of authority in the eyes of Google and other search engines. It’s like attaching a reference letter from Bill Gates to your CV.
1) pending delete auctions.  These are domains that were not renewed and are going through a pretty complicated drop process.  You can backorder these names at the auction venues and then each attempts to "catch" the dropping domain.  If one is successful you win the domain at $59 if you're the only one to backorder the name.  If more than one person backordered the domain a 3 day private auction is held.  Once the domain goes through the drop process, the back links have pretty much zero SEO benifit to the new domain owner.
It’s easier to rank higher with expired domains: Depending upon your domain age, page authority, trust flow, expired domains tend to rank really well when compared to new domains. Most new domains don’t have any DA, page authority or trust flow so it’s really harder to rank well in Google. This won’t happen with the expired domains as they are already established well and might be getting decent amount of traffic from search engines.

While traffic, as an abstract, is fairly easy to understand and get, getting it on a consistent basis is another matter entirely. That’s why a lot of affiliate marketers who are serious about generating online traffic are quickly paying attention to drop domains. Drop domains is not a new phenomenon. People have been registering drop domains for many years now to scoop up traffic that those domains still attract. However, as Google continues to crack down, and as more social media platforms impose anti marketing rules, or rules that have an anti marketing effect, drop domains have become more prominent in the online marketing landscape. If you would like to tap into a fairly easy and potentially powerful source of online traffic, consider drop domains.
Expired domains with page rank, Alexa, TF, CF, Backlinks, DA, PA, RD, etc. are of much importance. It is because search engine values those expired domains because of their pre-built matrices. It can take you months to build that trust and then it will be of the value that you want. So, what if you can find expired domains with authority links like expired domains with CNN links, expired domains with Wikipedia links, expired domains with Huffington post links, etc. This kind of expired domains will provide you some great juice for your money website.
I like to also click on the No Fake PR’s and No Unsure PR’s because a lot of fake page rank or page rank that’s been manipulated in the past and you want to make sure any authority that you see is real. Once you’ve picked all the criteria you want to choose, click on the apply filter button. This took our list from two million to 237. Now, even within that, that’s kind of overwhelming.
I registered for backordering with GoDaddy last year, as i saw goddady was the registar of the domain i wanted. However when the deadline for renewal came, i got a message the expiration date had changed to expire… well, a year later, i.e. now in 4 days. How can the expiration date be postponed? Was that the registrant renewed? does that mean the domain never becomes available and never goes to auction?
There are a lot of tools online that you can use to grab expired domain lists, but the tools that you can find here is unique because of its features. You will have great daily updated expired domains list with different TLDs that can be valuable for your work. This tools will find you deleted domains on different criterion. You can search by domain name search option and can have some great domains like you find on other websites like Fresh Drop, expired Domain, etc.
Internet Marketing is one of the best fields which have a great output potential, but using suitable tools for different tasks is what make it interesting. For newbies, it may not understandable, but for professional internet marketers, tools are everything. Among many tools of SEO (Search Engine Optimization), expired domains finder that finds expired domains with already build matrices are most attractive things. Online marketers are well aware of the fact that time is everything, so they try to find domains that have already great values to spare their time.

Once you get to this point you know there have been DMAS listed. They have a number of domains linking to them and according to the way back machine which is WBY, you can see their site age. So, if you want to go with an older site you can see right here whether or not this is a site that you might be interested in, but before pulling the trigger you do want to check two things.
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?
Quite a lot of the time majestic trust flow will be great but ref domains below 10 but when I check ahrefs its considerably higher for ref domains. Without ahrefs I would of passed over these domains and missed out. Worthwhile addition if your building a lot of pbns. I also use linkultra backlink for my final spam check as it checks language,site type and if backlinks are comment, profile spammed etc enabling me to check if the backlinks of the domain are solid very quick.

For example: If the domain name DomainSherpa.com is registered with Moniker (the registrar) and the domain name reaches expired status, within a few days of expiring the domain name will be listed at SnapNames.com (auction house partner to Moniker). Domain names are exclusive to one auction service, as an auction cannot take place at two locations.

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.
GoDaddy Auctions is a marketplace where GoDaddy lists domains that have expired and are in the renewal grace period. Apart from these GoDaddy also lists other domains, but the expiring auctions at GoDaddy are the most popular. Based on the percieved value of the domain, domainers and SEOs bid on these auctions. If the original owner does not renew the domain, the top bid wins the auction and gets the domain name.
