Some months ago, I bought a domain name for a mistake .. the site got PR1 with some good posts but the name is so orrible that I don't get much traffic for my niche. Last week I finally bought an EMD for my niche that should boost my traffic a little. So, I've changed the domain pointing the new one to my niche website and I've set a 301 redirect from my old domain to the new domain. Now the question: Is it safe to blast the old domain with some heavy fiverr gig? Can I exploit this change, when G is surely crawling my new domain and updating the index, in some way?
