I'm getting ready to promote a handful of very keyword / product specific domains, and am looking for opinions on blasting the hell out of them vs. manually commenting. I've been able to find just under 30 d0follow, auto approve blogs for this experiment. Once I found a blog that was d0follow & verified to be auto approve, I used Scrapebox to harvest the inner pages, saving any that were PR1+. In the end I'm left with just under 7k pages across 29 domains that meet this criteria. (About 25% are PR3+.) This took some time to put together, but it was worth it. However, not all are compatible with Scrapebox. And I'm not sure I'd want to use Scrapebox on them anyway. Alternatively, I've also got a huge list of blogs that can be blasted with Scrapebox. But the majority are junk blogs, to say the least. Though I can quickly get thousands of backlinks by blasting them. I'm leaning towards manually posting 20+ comments for each of my domains, spreading them throughout the different blogs, and ensuring that they're on topic and relevant to the post. It will take some time, but this way I can verify that I'm getting PR3+ backlinks that are d0follow. Would such a small amount of (quality) backlinks be more beneficial than potentially 1000-2000+ "junk" backlinks? Just looking for opinions.
