Hi, i have a multisite install and the smartcrawl configure for that. Also i have the domain mapping for the domains, and i have the subdomain and the domain for access the site inside the network, like mackrom.powermarketing.es and mackrom.es but i have something strange in the google search, i have the results for the mackrom.powermarketing.es inside the powermarketing.es and i don't like that, how can i deselect the subsites of the network for appearing in the searches of the principal site?
