I hear a lot about buying aged domains for your niche. Lots of benefits and shit and all that. One benefit besides the domain age is the links back to the domain. These links are built by the previous owner. These backlinks are good until they are taken down or deindexed. Soooo... The links to the main domain are good. What about the links to the inner pages. Ain't they still good too? Hell yeah they are. But what inner pages? Use the wayback machine: http://www.archive.org/ Enter your domain name and find a previously cached snapshot of your domain and click links to inner pages. Create these same page name urls on your newly acquired aged domain. Add appropriate content, interlink and enjoy the inner page link juice. Disclaimer: I aint ever bought an aged domain but I know this will work through other experiences.
