I have hundreds of niche forum posts that are used as Tier 1 ******** backlinks for my money website. These forums are the most authoritive forums in closely related niches. So I believe that this is a smart way to build Tier 1 backlinks. But since they are forum threads, there are millions of them on these forums and they have very little link juice. So I believe that I should build backlinks for them. (Let me know if I am wrong so far) I want to have: - maximum benefit (max link juice), - maximum security (no google ban for long term - of course not guaranteed) - minimum cost What is the best way to build backlinks for them (so backlinks will be Tier 2)? Here are some options that came to my mind so far. Please evaluate them and give me some new ideas if possible. 1. I can blast them with GSA and then build Tier 3 links for GSA links (e.g. Tier3: blog comments) 2. I can build general (not niche related) low OBL blog comments. 3. I can build niche low OBL blog comments (costs much more compared to previous two) 4. I can buy cheap PBN guest posts like the one on the following thread and then blast them with GSA or blog comments. https://www.blackhatworld.com/seo/lovers-blog-posting-service-up-to-750-posts-starting-at-15.648043/ 5. I can buy cheap SEO services for my tier 1 links but I don't think that this is cheap enough. I think I should spend 50-60 USD for every 3-5 Tier 1 links. And this seems to be waste of money for Tier 2 links. If you know a cheap SEO service that is appropriate for this purpose, let me know. 6. Your custom suggestion (e.g. any method or services you suggest). What is the most effective and safest approach to give strength to Tier 1 forum posts? Please tell us reasons for your choice.
