Google Penguin is an algorithm update introduced by Google to target websites that engage in webspam tactics including keyword stuffing, paid linking schemes, etc, and use unnatural backlinks to rank higher in Google search results.
Penguin targets
- Keyword stuffing
- Over-use of the same keywords for internal site links
- Paid linking schemes
Link building from irrelevant (as opposed to niche) sites - Development of shallow inbound links rooted in the same keyword
- Countless websites use these techniques to exploit PageRank and give the impression of high-quality content. They are, however, actually using SEO best practices to boost their search rankings without having a good user experience
