One little known and untapped market for passive income seems to be buying expired domains. When a website owner for whatever reason doesn’t renew their domain name it’s up for grabs.
Since many of these domains/websites had advertised around the internet before being left to expire traffic keeps coming in. When you buy an expire domain you can take advantage of this free traffic by redirecting it to one of your websites, building a new website with the domain, or setting up ads on it via domain parking.
If you don’t have a website to direct the expired domains traffic to setting up the domain with ads is an ideal way to create passive income. Sites like parked and godaddy will set up the ads for your expired domains and pay you the revenue it generates monthly.
For some reason I rarely hear of internet gurus mentioning this tactic but it can generate a nice passive income with no work involved for the domain owner. You can buy expired domains for as little as $20 each over at godaddy.
