Webspam (also referred to search spam) is a phrase used to describe webpages that are designed to “spam Google search results” using SEO tactics that are against Google publishers guidelines. Pages that use webspam to improve search engine results page (SERP) rankings typically use black hat SEO tactics such as keyword stuffing or cloaking, the latter of which involves employing misleading redirects and/or doorway pages of websites.
In April 2012, Google announced its Penguin-codenamed “Webspam Algorithm Update” that better identifies websites using aggressive webspam tactics.
