Welcome to Wikipedia. Although everyone is welcome to contribute to the encyclopedia, one or more of the external links you added to the page Cauchy–Schwarz inequality do not comply with our guidelines for external links and have been removed. Wikipedia is not a collection of links; nor should it be used as a platform for advertising or promotion, and doing so is contrary to the goals of this project. Because Wikipedia uses nofollow tags, external links do not alter search engine rankings. If you feel the link should be added to the article, please discuss it on the article's talk page before reinserting it. Please take a look at the welcome page to learn more about contributing constructively to this encyclopedia. Thank you. JohnBlackburne wordsdeeds 10:05, 9 November 2011 (UTC)

The link provided was intended to put example for practical application of Cauchy–Schwarz inequality. Unfortunately JohnBlackburne has mistakenly put it as spam link without even check the detail of the link.
 * See WP:SPAMLINKS: "Adding external links to an article or user page for the purpose of promoting a website or a product is not allowed, and is considered to be spam. Although the specific links may be allowed under some circumstances, repeatedly adding links will in most cases result in all of them being removed." In your case it seems your main purpose here is to spam your links across multiple articles, not improve the encyclopaedia. See also our our external links policy, especially #5.-- JohnBlackburne wordsdeeds 14:28, 10 November 2011 (UTC)
