Yes, we port in all of the domains from NameJet, SnapNames, etc. There are a lot of great deals to be found. Some are absolute trash of course but if you can sift through them and put some time in (hopefully that is what we are trying to do with our tools is save time and give some value add with the SEO metrics, alerts, etc.) then you can find some great bargains.
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.
By using GoDaddy auctions section, you can also use keywords to search the domain names that you are interested in. For instance, if you type the keyword something like “fitness”, it will list you out all the domain names that matches with the keyword “Fitness” so you can easily make a list of all the domain names with your desired keyword selection.

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!

Since high quality expired domains are in low supply, the huge numbers of marketers competing for those drop domains tend to drive prices up. Also, if you use an exchange, you’re basically lucky to get whatever you can afford. In other words, niche specificity isn't guaranteed. This is going to be a problem because as Google continues to evolve, it is cracking down on domain niche relevance. In other words, its software is fast evolving to the point that it can tell what the niche of a particular domain is. If your private blog network is a patchwork of expired domains that involve many different and dissimilar niches, then you might be in trouble. You are at great risk of being penalized by Google.
If it contains any of those, then I am going to crawl it. Otherwise, I'm not going to because it's probably just something like an Amazon listing. Okay lets move on to the endless cruel. So this is the endless crawl. Basically, here you put your seed websites, one will do if it's a big website, because there's probably loads of domains on it. If it's a tiny, tiny a website, then you might want to stick a few more in so, as I was saying before, it will crawl on all the pages on these websites and then for each external domain that it finds on that website. It will check whether it's expired if it's not expired, it'll try and crawl it and then it will start the loop again, it'll try and take all the domains from there check that they are expired.
Searching for a suitable domain name for your website can be quite trying. The reason for this is that the names that you want to get have already been assigned and are not available. As an SEO you know the importance of getting a domain name that describes your business as closely as possible. For example, if you are running a car rental service, you will look for a domain name that has the words ‘car’ and ‘rental’ in it. So if you can’t find a suitable name, you could use the expired domains tool which might show you domain names that would meet your requirements.
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.
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 and you buy and 301 redirect the domain over, you're inheriting a lot of topical and appropriate links.
Domain names expire when someone decides to stop renewing it. They may not be available to register immediately. We update the search index every night, so some names may already be renewed or re-registered. Some may become available in a few days. Some registrars, like GoDaddy, will let you buy a name that one of their own customers expire immediately. When you find a name you like, just click on it to try backordering the name!
