I am starting to see a lot of expired domains reuse as a money site in health niche. This made me think twice if I should put my new articles on my current site (which could be de-valued by google already) or should I buy expired authority domain and put the contents on it. Some of the domains that rank #3-4 position on my target keyword don't even have health related backlinks point at it. And the domain name is ridiculous something like "city-conference.com" ....on health keyword wtf???
