The niches I work on are easy to target and vulnerable. Most are in the gray market, and once I dominate Google’s top 10, I always get so called “negative backlink attacks” from competitors.
The first time it happened I got scared. Most of them use kitchen sink links like explolits to adult video tubes etc.. which I never even bother to build. I only build backlinks using automated tools like GSA Search Engine Ranker (aka GSA SER), RankerX, and XRumer AI. But I only use top-quality link lists and engines.
Competitors blast my domains with nasty pharma anchors, etc. Guess what...my rankings actually stabilize, and I love it.
My conclusion...there’s no such thing as “negative backlinks.” I still don’t build nasty anchor texts, exploits, or backlinks from adult video sites, but they don’t hurt at all. In other words, so-called negative SEO can even help. I don’t think it really exists.
