A toxic backlink is an incoming link to a website that can negatively impact its visibility and ranking in search engine results (SERPs). These backlinks often come from low-quality, spammy, or irrelevant websites and are considered unnatural by search engine algorithms. Toxic backlinks can harm a website’s SEO performance by signaling to search engines that the site is engaging in manipulative or unethical link-building practices. Identifying and disavowing toxic backlinks is crucial to maintaining a healthy backlink profile and protecting a website’s search engine rankings. By addressing toxic backlinks, website owners can prevent potential penalties and ensure that their site is recognized for its genuine quality and relevance.
