Doublemint - Double Trouble
Illustration I used for an article on Duplication Issues. In search engine optimization, there are frequently cases where a site will have many URLs delivering up the same, identical content on the page. This causes search engines to have to choose which page URLs to display, and it results in PageRank getting spread thinner than necessary across a site's pages, resulting in sometimes lower rankings for those pages in search engine results.
