Negative SEO is both Highly Effective and Extremely Misunderstood

Negative Search Engine Optimization (NSEO) has been hotly debated in the SEO sector for well over a decade now, but despite all the noise made by Search Engine Optimizers around the globe it is still one of the most misunderstood SEO tactics of all.

That’s because the majority of professionals in the sector still see Negative SEO as little more than link-spam, malicious linking attacks (Googlebombing,) and/or “Hacks” without ever considering the true scope of possible attack vectors. What’s more, Google has deliberately downplayed the efficacy of Negative SEO attacks for at least a decade now, thus helping to muddy the waters for those of us whose task it is to clean up the damage caused by NSEO used against legitimate enterprise.

Doctor Evil: "Hacks"

Add to that the “Code of Silence” in the SEO sector, because most ethical professionals “don’t want to give ideas to the bad guys…” and what you have is the perfect storm to create a rapidly expanding field of malicious actors using an array of underhanded techniques unchallenged.
