I've been very cautious with my link building for my money sites. I have a number of high quality niche relevant contextual links for tier 1, primarily acquired through webmaster outreach, and continue to build them at a slow and steady pace. The site has plenty of link diversity with naturally occurring links. I have been unhappy with our recent ranking progress and am looking to accelerate things while minimizing risk. I have found several well reviewed PBN services here on BHW. I have a few questions that I hope you could help with... 1) Would it be effective, for my money site, to hit my tier 1 links with PBN posts from BHW? 2) If so, what should I use for anchor texts to the tier 1 links? 3) How much risk would I be exposing my money site to? 4) Any other suggestions on how to proceed would be greatly appreciated.
