I'm just starting to get back into SEO. I haven't done much developing in the last few years, and I'm trying to catch up on some new techniques. The more I read about PBN's the more intrigued I am. Can anyone give me some input on whether it's worth the time to setup a PBN? Note: I plan on publishing to the PBN over time and I'm not looking for a quick fix to blast a bunch of links. Also I'm considering grabbing scrapebox and was wondering if it's worth the $100?
