The web is constantly evolving. This goes beyond just the content on websites; whole domains can be taken over, allowing corners of the internet to become a little like your hometown: Wait, wasn't there a Dairy Queen here?

If TechCrunch doesn't pay its domain registrar, it will eventually expire on June 10. At that point, someone could buy the domain and use it for bad things. If TechCrunch.com was suddenly red instead of green and sold penis enhancement pills instead of dicking around with great news and awful puns, you would probably figure out that something is up. Black-hat tricksters are more subtle than that.

When they seize a domain, they will often point the site to a new address and leave it there for a while. The experts claim that when the address changes, the domain is dropped from the rankings.

During this time, the domain is put on notice by the search engine. The theory is that the domain will start climbing in the rankings again once it's been determined that the change to the IP address underneath the domain was just part of a move from one web host to another. When the new owner of the domain can start their business of updating links to send traffic to new places, or keeping traffic as it is, it's when they can start making money. They can use the good name and reputation of the original business to scam or trick users at the far end of the scamming spectrum.

The transferability of trust has been a factor in determining what makes a good website. A site that is linked to a lot of high-trust websites can be trusted. Links from that page can be used to measure trust. The more links from high-quality sites a page has, the more trusted it is, and the better it ranks in the search engines.

You don’t have to dig deep to find examples of domains that, at first glance, look legitimate, but that have been sneakily shifted to another purpose.

Bad actors can take advantage of this fact, but sites move from one host to another all the time for legitimate reasons. As Danny Sullivan pointed out when I talked to him about expired domains last week, there have been a few changes of owners over the years, from AOL to Oath to Yahoo, which itself was bought by Apollo Global. There is a chance that the new corporate overlords will want to move stuff to a new server or technology, which means that the addresses will change.

The domain registry would have changed, but the site itself didn't change the nature of what it was. Sullivan said that it is possible for the content to change without the underlying architecture or network topography changing.

The buying and selling of expired domains

You don't have to look very far to find a place to buy an expired domain. Some of the most active companies are Serp.Domains, Odys, and Juice Market. I stuck a rel on all three of the links in the article. They are not getting the sweet, sweet link juice on my watch.

The company Serp Domains has a list of around a hundred sites for sale, with prices ranging from $350 to $5,500.

Odys advertises on its site that expired domains can be used to get authoritative backlink since they were actually businesses.

The domains are for sale from a few hundred dollars to thousands of dollars. Seeing the sites disappear from the list and then reappear on the internet shows that some of them are questionable at best.

It's easy to understand why people are willing to go through all the trouble of building a domain and waiting for people to link to it. Finding a way to shorten the process and add the ability to make a quick buck is a good way to go. There will always be people who are willing to do that.

Patrick said that inbound links are one of the top three ranking factors.

What the spammers are doing

A search engine optimization tool like Ahrefs can be used to gauge how valuable a site is by checking how many links are going to it and how valuable those links are. A link from WhiteHouse.gov would be very valuable. A link from a random post on Medium.com is more likely than not.

Once they have found and bought a domain, they will use a machine called the Way Back Machine to copy an old version of the site and put it on a server. If you're in the market of scamming, that's probably the least of your crimes.

Sometimes weeks, sometimes months, sometimes weeks, sometimes months, sometimes months, sometimes months, sometimes months, sometimes months, sometimes months, sometimes months, sometimes months, sometimes months, sometimes months, sometimes months, sometimes months, sometimes months, sometimes months, sometimes months, sometimes months, sometimes The next phase of the plan is to sell stuff or trick people, and traffic will start picking up. There are a lot of guides for what to do next in order to use these domains, including checking whether there are trademarks registered, and redirecting the full domain or specific pages on the domain using a so-called 301 redirect.

When a site goes down on the internet, it's going to drop all the signals from the links. That happens when a page ends. Whether or not those signals will come back for a new owner is more complicated. If the same site with the same type of content, I don't think it's clear how to answer this. If you were a site about technology and now you are a food blog, all of the previous stuff will likely be ignored.

Negative signals continue on expired domains, so it stands to reason that positive signals do as well.

Sometimes penalties will still carry over regardless of the content of the new site. There is a giant list of penalties that can be avoided by buying an expired domain and putting a new site up. Nothing is ranking, and on closer inspection, they will find a penalty in the search console.

Sullivan told us that the search engine giant knows what it is doing and has a handle on it.

Sullivan pointed out that the company's robust spam filters are there and that all purchased sites should be treated as spam. We keep out of the top search results hundreds of millions of pages and sites. One metaphor I like to use is that if you go into your email folder, you will see all the emails that you didn't see. That is what is happening on search all the time. Our search results would look similar to what you see in your inbox if we didn't have robust filters. Our systems are in place to catch it.

There is a thriving industry for high-value expired domains that are available, whether for honest attempts to corner-cutting or more sinister actions.

A thriving industry

You don't have to dig very deep to find examples of domains that look legitimate, but have been sneakily shifted to another purpose. I came across a few of them.

The paid leave project moved its website to USpaidleave.org at some point, but it was still on paid leaveproject.org. The site that used to help workers in the U.S. get paid family leave was not renewed by the org.

The paidleaveproject.org appears to be an affiliate site for ED pills.

The original owner of Genome Mag doesn't have control over the magazine, which came back online as a different magazine after it expired.
