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.
What I like to do is sort by DP which stands for domain pop, and this is basically the number of linking root domains. So, BL is the number of back links. As you know that can be somewhat misleading if they have a lot of site wide links or multiple links from the same domain. I like to sort by domain pop. What that does is it brings up the sites with the most amount of referring domains.
Your course of action really depends on how much work and effort you can put into the expired domain. If you're barely able to maintain and optimize your current site, you probably want to just 301 redirect the old site (note: see my amended comment above about the link value not likely to be passed). If, however, you're more creative and have some time on your hands, you can try your hand at crafting a microsite. If you really know your stuff and are experienced at making money off various websites, you'd probably do well with the third option.
When searching from keyword DHG will take your list of keywords and search each one, the pages will then be crawled to find unique domains to check availability of. The process is relatively simple but very time consuming when done manually or semi automated as was necessary in the past. Luckily now the job can be set and left to work while you do something else.

That’s awesome. For someone that’s willing to “dial for dollars”, I bet there would be a percentage that would convert. It’s a funnel, and the more you put in the top, the more you’ll get out the bottom. 66% success rate sounds high, but I have no data…one would have to try it and see. If anyone is interested, I’d love to interview you after you’ve made the calls and gathered the data!
Contains, Starts, Ends You can use the search bar to search for domains that contain particular keywords you are seeking, e.g. a search for "car" will yield results for all expired domain names that contain the term "car". You can also use the search tool to find domains that begin, or end with the search term too, with the drop down box next to the search form.

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.

Yes, I know, it seems backwards that you’d have to compete in an auction for a domain name that may never be caught. Other people feel the same way and many don’t compete as a result of that. But that’s the way the drop catching service was set up. Who knows, it may mean less competition for you since others do not like that model, which benefits the company rather than the user.

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.
The easiest way to see that is to go to HREFs and look at the anchor text. It reveals right away whether or not the site has been spammed. You also want to see if it’s been SEO’d too much. Right? In this case, it’s not because it has a brand name here and some natural keywords, but if the number one anchor text was like, cell phone management system and then the next one was like cheap cell phone management system, you’d know that the anchor text was manipulated and probably overly SEO’d. So, what you want as a site that has a natural link profile.

Hi Michael, thanks for the excellent writeup. I followed your steps and found that the domain name I’m seeking is currently registered with GoDaddy. Interestingly enough, I actually owned this domain name almost a decade ago, but out of laziness (at the time), I didn’t renew the registration. Someone else snatched it around the same time and has had it since. The website is dormant, with only an embedded video playlist from a YouTube account last updated over a year ago. The website itself hasn’t changed in appearance for several years.
But unless the domain name you want is undesirable to anyone else (e.g., it does not include real words or have a high search volume for the words), the odds are not in your favor. With over 210 million domain names registered and an active, worldwide domain name investing community, it is highly likely that someone else will also find interest in the domain name you are watching. As such, skip to Step 4.

Warehousing: I have no clue to a percentage of warehoused domains but I know it happens. Tucows even admitted it on my blog “I know you don’t like that we’re allowed to select expiring names for the Tucows Portfolio rather than letting them all go to auction or drop but that seems to be something we have to agree to disagree about.” ~ Ken Schafer (1st comment)

[1] On April 11, 2016, SnapNames (owned by and NameJet (partnership between 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.
Why does this matter? What's the big deal? Well, unfortunately, the vast majority of domains registered are eventually abandoned. For some reason or another, people just fail to re-register or renew their domain name and that domain name drops or becomes available to the public. Of course, the obvious reason is that these people simply did not make money off the website that they put up with that domain. Other bloggers and website owners simply don't have the time, so they just gave up on their online projects. Whatever the case may be, by simply registering these expired domains, you can resurrect the value they bring to the table. With the four situations that I outlined above, you can benefit from those situations by simply registering a drop domain.
The whitelist filter for wanted characters is now split into three filters. The old whitelist is now named whitelist (only). When used, the domain has to consist only of the defined characters or numbers. No other characters are allowed. The new whitelist (any) filter finds domains that have at least one of the defined characters or numbers. The new whitelist (all) filter finds domains that have all defined characters or numbers at least once.
