I got many domains with a friend that we bought several years ago.They are mainly focused for Marketing, Branding, and Keywords great for content network.I am thinking that we must arrange the priority and build:Landing pages: (mainly for PPC campaigns) we look to convert, client filling their data so we call them back. Content Networks: Creating good content and post on all social networks. Many niches, many categories.Shall I do it this way? if I link to a same company? All Landing pages with partnership with that same company. Google wont penalize me? I then can create many backlinks pointing to clients pages. Building PR and authority.What you all guys think?Which way shall I go?Thanks in advance.
