Tony_d gave me a good suggestion yesterday. The topic was getting my coworkers/gatekeepers on board with some of the more aggressive link building SEO tactics (the sort we discuss here). They're somewhere between opposed and lukewarm to the idea. So, Tony_d suggested building a second site, proceeding with what we here know to work on a "second site" and warming my crew up to the possibilities of the impact on our primary sites. So, my question now is this: Can that "second site" be our G+ or Twi or Fboo pages? Or should I invest the time and energy to do this against a bonafide second site (ie, domain)? Thanks in advance for the helpful dialog ahead.
