Site reputation abuse -- also called parasite SEO -- refers to a website publishing a deluge of off-brand or irrelevant content in order to take advantage of the main site's ranking power and reputation in Google Search. Often, this piggybacking is concealed from users browsing the website. (For instance: those weird coupon code sections on newspaper sites that pop up via search engines but aren't prominently displayed on the homepage.) Sometimes this spammy content is produced by third-party marketing firms that are contracted to produce a mountain of search-friendly content.
