Out of all the links indexed for your sites, roughly what percentage would you say are auto-approve links from scraped blogs, vs moderated/hand-edited/paid links? I mean this as more of an overall estimate of every site, not necessarily one example of a single site or page. Could you rank solely by using an auto-approve list and nothing else? As you might guess, I'm setting up some tests now, but I'm sure it will take me a few months to get enough data before I can make an informed decision. I'm also considering a few paid memberships for link building on private blog networks (I'm sure you guys know a few examples without mentioning names)... I really want to know whether that is worth it or if I'm better off using scrape_b0x, article marketing and forum profiles/comments. Any input is greatly appreciated!
