When searching from keyword DHG will take your list of keywords and search each one, the pages will then be crawled to find unique domains to check availability of. The process is relatively simple but very time consuming when done manually or semi automated as was necessary in the past. Luckily now the job can be set and left to work while you do something else.
It’s easier to rank higher with expired domains: Depending upon your domain age, page authority, trust flow, expired domains tend to rank really well when compared to new domains. Most new domains don’t have any DA, page authority or trust flow so it’s really harder to rank well in Google. This won’t happen with the expired domains as they are already established well and might be getting decent amount of traffic from search engines.
2) prerelease auctions. These are domains where the auction venue has contracted with the registrar, like Fabulous or Moniker, to auction off non-renewed domains. Just before a domain enters the pending delete process, it goes to a private auction to any person who has backordered the name. Some people feel that back links on these type of auctions still provide a SEO benifit. My testing indicates that there is zero SEO benifit when these domains are redirected into another site. So if you get a domain with "pink squirels" in a lot of achor text to a domain and then point it at your domain, you don't rank for "pink squirels"
