Grey Hat SEO is the optimization strategy that lies between the White Hat and Black Hat approaches. Compared to the unethical Black Hat techniques, Grey Hat SEO practices are not explicitly condemned in Google guidelines but still tend to manipulate the system. Website owners often resort to such tactics to boost the page rankings by illegitimate ways but still not violate the terms of service. Traders usually buy expired domains, engage in link trading, use content spinning and private blog networks to take advantage of the loopholes. Since such methods are not completely banned by search engines, they are often used to take a short-term rankings gain before Google patches the vulnerability. Grey Hat SEO is usually a risky endeavor because the constantly evolving algorithm updates tend to penalize websites that use such tactics. The link networks and expired domain purchases are considered spam, thus applying such methods means risking a site’s visibility on Google. In most cases, the manipulations do not result in a site ban but rather a temporary penalty depending on the severity of the violation. Grey Hat SEO is generally more dangerous than the safe but slow White Hat methods. The manipulative tactics are usually designed to surpass the competitors using unscrupulous means. Since the unethical strategies are not explicitly banned, one should have a thorough understanding of the intricacies of search engine positioning to avoid severe penalties. Essentially, Grey Hat optimizers use manipulative tactics to gain ground on the search engine results pages. As such, SEOers who want to avoid any risks associated with unethical tactics are better off with the White Hat approach that keeps their site safe from algorithm updates.
