The Google Panda update, launched in 2011, aimed to lower the rankings of low-quality websites while boosting high-quality content. It targets issues such as thin or duplicate content, low-quality user-generated content, and high ad-to-content ratios, emphasizing the importance of relevance and authority in web content. Although Panda has evolved into the Coati algorithm, its principles regarding expertise, authoritativeness, and trustworthiness remain integral to content evaluation.
