Please do not add inappropriate external links to Wikipedia, as you did to Search engine optimization. Wikipedia is not a collection of links, nor should it be used for advertising or promotion. Inappropriate links include (but are not limited to) links to personal web sites, links to web sites with which you are affiliated, and links that attract visitors to a web site or promote a product. See the external links guideline and spam guideline for further explanations. Because Wikipedia uses the nofollow attribute value, its external links are disregarded by most search engines. If you feel the link should be added to the article, please discuss it on the article's talk page rather than re-adding it. Thank you. bonadea contributions talk 14:03, 21 March 2012 (UTC)[reply]

Please stop adding inappropriate external links to Wikipedia, as you did to Amazon Kindle. It is considered spamming and Wikipedia is not a vehicle for advertising or promotion. Because Wikipedia uses nofollow tags, additions of links to Wikipedia will not alter search engine rankings. If you continue spamming, you may be blocked from editing Wikipedia. --SubSeven (talk) 13:53, 30 April 2012 (UTC)[reply]
