Expired domains are simply a domain that was not renewed at the end of it’s registration period. These types of domains often have considerable backlinks and a content history that can be leveraged to get an early boost in indexation and ranking for websites, amongst other uses.
Expired domains can be registered for the same price of a fresh domain so they are a great choice for building a new website on, or for recovering an old website along with it’s content.
You can use a tool such as Domain Hunter Gatherer to find expired domains in any niche with backlinks from high ranking sites in any niche.
