Hi guys. Lets say I have an authority website and it ranks #1 for a 5k keyword. And I use only high quality manual backlinks with 3 tiers. And this site has 100 posts. And I want one of the posts to make rank for a keyword that has 150 monthly searches. And I start using GSA or any service to create links to this specific post. But unfortunately these links were spam and it hurts this post sadly and its rank dropped strongly and may be it de-indexed also. My main question, will this trouble harm my main site ranking?
