Hi all, I know that it may be newbie question to ask but need some fresh thoughts from BHW family. Recently I was running ahrefs backlink competitors analysis for my business, found out that most of the Google Top 5 searches in my niche have from 200k to over 1mil backlinks. I dug further to check where they came from. What I discovered was confusing, over 15k backlinks from one domain, 10k from one domain and so on, repeated hundreds of times. It clearly looks like work of some SEO automation tool but it's surprising for me that it was done on tier 1 money websites. How it is possible that such websites are not penalized? Is such tactic worth it at the end? Thanks for ur thoughts on this!
