So, I have about 4 sites, all targeting the same niche. All of the sites are registered in Google Webmaster under the same account (different sites, but same webmaster account). My question is, is this harmful to me? Does google not count these as individual sites because they're all registered on the same webmaster account... so google thinks they're kind of "the same?" In other words, is it like having all your sites on one IP? Anyone know?
