I have a month old site that I am building a big blog on. It is non-EMD and actually brandable. I am thinking of buying an aged expired domain and 301 one of them to the other. My purpose is to be able to build links faster and also hope the age of the domain will somehow help in SEO (not many backlinks in the new domain unfortunately). I am also thinking I should probably go with an EMD of some sort, or partial at least, instead of a brandable domain that nobody will know. This has been done before numerous times before, but is it recommended? Would it matter if I 301 the old site to the new site (extremely new from expired domains pile), and not the other way around?
