Many people have heard or read of the practice of buying expired domains, but not many fully understand what the benefits of doing so are and how to go about it.
1. Build an Authority Site
If you are thinking about building a new site or blog, consider purchasing an expired domain rather than a new one.
2. Use It For Backlinking Purposes
Instead of building an entire site, you can also build a small mini-site for the sole purpose of linking to your main website or blog.
3. Redirect the Site
If you want to transfer the link juice of an expired domain to your main website without going through the process of setting up a mini-site, you can skip ahead by simply redirecting the old domain to your main website. This can be done via a 301 redirect.
4. Sell It For Profit
Another reason people purchase expired domains is simply to sell them. This is also known as domain flipping, and some people earn their livelihood from it.
