Let’s say a certain site, blah.xyz.com, gets a ton of traffic (yes it’s a subdomain). How many people forget to put that period in and type in blahxyz.com in their browser? A lot. Why let those people go to a blank page? Spend $10, buy that entire subdomain string without the “.” (blahxyz.com if available) and send those visitors to a landing page of your choice (perhaps related to the target site) or just park a page there at the least. Once you buy the domain you WILL get free traffic. No doubt about it.
You can make a lot of money with this technique. Just do some research and find a subdomain that gets a lot of traffic, then check to see if the subdomain string without the period is available. I’m keepin this post short because there’s really not much more to it. There are more techniques but I’ll talk about those in a later post.
