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.
By strategically buying expired domain names which have certain quality features, you can create a link "pump" to your target sites. From an SEO perspective, this can turbo charge your rankings on Google and other search engines. Also, you can make money directly by promoting products on high ranking search results. Additionally, you can make money by selling links on your network to people looking to get an SEO boost.

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.

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.
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.
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.
Here's an old post on search engine roundtable that claims google's policy is to discount previous backlink juice when a domain changes ownership. I'm not convinced whether this is actually true or something Google says to discourage excessive domain buying / 301 redirecting for SEO benefit. The comments above seem to give varying opinions on this matter. Would be great to get to the bottom of that one!
Hundreds of thousands of domains expire everyday. While most of them are trash, quite a few are aged domains having excellent backlinks. These can be easily filtered using metrics from Majestic (Trust Flow) & Moz (Domain Authority). These are great for your money sites or for building private blog networks. Some of these domains have natural organic traffic, that can be determined by their SEMrush rank or the SimilarWeb data. These are great for domain parking or for promoting affiliate offers.
