I've raved about this on other threads, and I do believe it has an impact in ranking. However, this isn't for new sites. I'd say that the benefit of using 301s comes from using these on your web 2.0s, as well as using them directly for parasites. I'm in the process just now actually of writing up a case studying regarding this very matter. In it, there's going to be three fiverr gigs used, one of which is mine, and two by two other sellers that I have had good results with this. When I've used this method before, it's been on parasites that I've let 'bed in' for a while (normally at least 6 weeks), so I'm curious how well a parasite can take a pounding with this method within a week of going live.
