I have a new domain name. I heard you shouldn't blast away backlinks to brand new domain name. If that is so, how much backlinking is safe? 1 backlink a day? 10? 100? Also, I plan to put this domain name on a SHARED Bluehost hosting account where I host my aged domains that I blast tons of backlinks to. If Google decides to de-index my NEW domain name, I'm worried they will also kill my other older sites hosted on the same account. So should I have a separate hosting?
