Meta-tag stuffing
This involves repeating keywords in the Meta tags, and using meta keywords that are unrelated to the site's content. This tactic has been ineffective since 2005.
Scraper sites
Scraper sites are created using various programs designed to "scrape" search-engine results pages or other sources of content and create "content" for a website. The specific presentation of content on these sites is unique, but is merely an amalgamation of content taken from other sources, often without permission. Such websites are generally full of advertising (such as pay-per-click ads), or they redirect the user to other sites. It is even feasible for scraper sites to outrank original websites for their own information and organization names.
Link spam
Link spam is defined as links between pages that are present for reasons other than merit. Link spam takes advantage of link-based ranking algorithms, which gives websites higher rankings the more other highly ranked websites link to it. These techniques also aim at influencing other link-based ranking techniques such as the HITS algorithm.
