Parked domains are usually not something that you want to lead your visitors to. In the best case, they are simply minor, useless annoyances. In the worst case, however, they expose a visitor to harmful software or other threads. We have seen numerous parked domain websites try to trick users into installing dubious browser extensions or malicious programs like in the screenshots below.

It is our experience that more than half of all registered domain names worldwide are parked in some way. In general, we categorize parked domains into the following four groups.

Domains that are up for sale.

Domains for sale

Domains whose sole purpose is to generate income from ads.

Domains filled with ads

Domains that are under construction or reserved for future development.

Under construction domains

Domains that are expired, suspended, or otherwise out of service.

Out-of-service domains

An accidental link to a parked domain can happen quicker than you might think – just make a small typo in the URL, for example, and you are linking to a completely different website than intended. Even larger is the risk of abandoned websites whose domains expire and then fall into the hands of domain-parking companies. If a link works today, it doesn’t at all mean that it will still point to the same content tomorrow.

Unfortunately, detecting parked domains isn’t easy because they typically return a 200 OK HTTP status code, just like any other website. This fact makes them impossible to spot with a normal link checker. Several parking domain companies also go out of their way to avoid detection, using rotating templates, frequently changing servers, or hiding behind JavaScript-triggered redirects. There’s a clear reason for this behavior: domain parkers want to keep as many backlinks as possible because they make their domains more valuable.

We at Dr. Link Check have developed a large database of signatures to identify parked domains based on DNS records, HTTP headers, and HTML code. Our parked domain checker is included with the Professional and Premium Plans. You can access the list of parked domain links found on your website by selecting Parked from the sidebar.

For optimal results, we recommend configuring a recurring weekly or monthly check in Dr. Link Check. This way you will be automatically notified by email when our crawlers detect a parked domain link on your site.
