Black hat marketing refers to the use of unethical and deceptive tactics to promote a product or service, often in violation of industry standards and regulations. This type of marketing relies on exploiting loopholes and manipulating algorithms to artificially boost visibility and sales, rather than providing genuine value to consumers. It can include tactics such as spamming, keyword stuffing, and buying fake reviews or followers. While it may yield short-term gains, black hat marketing ultimately damages a brand’s reputation and can result in penalties or legal consequences.
