NSEO, or Negative Search Engine Optimization, is the practice of deliberately manipulating search engine results in order to harm a competitor’s website or online reputation. This unethical tactic involves using black hat SEO techniques such as spamming, keyword stuffing, and creating fake backlinks to lower a competitor’s search engine ranking and visibility. NSEO not only goes against search engine guidelines, but it also damages the integrity of the online ecosystem by promoting dishonest and unfair competition. It is important for businesses to be aware of NSEO and take measures to protect their online presence from such malicious attacks.
