Parasite SEO is a digital marketing strategy that involves utilizing high-authority external websites to enhance the search engine visibility of one's own content. The term "parasite" reflects the strategy's dependence on the authority and reach of host sites, similar to how a parasite relies on a host for sustenance. This approach is notable for its potential to deliver quick rankings and increased visibility, making it an appealing option for businesses and marketers seeking rapid online presence without the extensive resource investment required for traditional SEO methods.

 The methodology of parasite SEO typically involves identifying suitable high-authority platforms, crafting quality content optimized for search engines, and strategically building backlinks. Marketers leverage these established sites to gain traffic and credibility, often leading to quick results in search engine rankings. However, this strategy is not without its controversies, as it raises ethical concerns about manipulative practices and the risk of penalties from search engines like Google, which may consider such tactics as spammy or misleading.
