First off, I want to say that in my experience Indian workers can do a great job and are highly focused workers that can more or less be depended on to stick to the job no matter how tedious. However in my experience, they need solid oversight. That said, even domestic US workers need micromanaging as well when it comes to link building. Doesn't matter who is doing the work, US, Indian, Philipine, I can't set it and forget it. I insist on receiving a BCC on every email sent. It's too important not to.
