I have been asked by a very close friend how to best pull off running two websites in the same niche without having big G throttling you or hurting your rankings.
He plans to have two sites that have similar, but completely original content on both sites.
He wants to know if he should use the same adsense / g analytics account or find a way to get multiple accounts.
My advice in 2012 would be to look as much as separate entities as you could. Zero footprint on all fronts.
Pre-2011 my advice would have been to just provide users with unique quality content for users and everything will work out.
What would your advice be?
