[edit] What is Search Engine Optimization
Search Engine Optimization (SEO) is a marketing strategy used to improve the rankings of a webpages in the organic or unpaid section of online search engines such as Google, Bing, Yahoo, Yandex, Baidu, Naver. SEO differs from paid search campaigns which are sometimes referred as Search Engine Advertising.
As part of a SEO strategy, webmasters use various techniques of webpage design to improve the likelihood that a page is at top of the search results with specific keywords. The most popular search engines rank webpages using a method called indexing, which determines which webpages rank highest for specific keywords.
It is estimated that the click through rate (CTR) for the natural sections of search engines is 75% compared to 25% for the paid sections [1]. For this reason, it is important for a company to work towards being at the top of a natural search. In addition, 63% of the clicks are on one of the top three search results [2]. Therefore, if a company’s links are not appearing at the top of the search results, people are less likely to find the products or services that are being marketed by that company.
People often don’t make online purchase decisions by clicking through on the unpaid section of search engines. Therefore, the unpaid sections can be viewed as an important area to promote the awareness of a company’s products or services. It is essential that an organization prioritizes the online metrics that it wants to drive through its SEO strategies.
In addition to traditional web search, other areas to improve SEO include videos, images, podcasts, news, and PDFs. These different web channels can be adjusted to improve the SEO performance.
SEO is also commonly used as an acronym for Search Engine Optimizers, consultants or service providers who aid clients in improving their webpage pagerank [3].

[edit] Legal Precedents
In 2002, SearchKing filed suit in an Oklahoma court against the search engine Google. SearchKing's claimed that Google's tactics to prevent spamdexing constituted an unfair business practice. In May 2003, the court pronounced a summary judgment in Google's favor.[6] In March 2006, KinderStart.com, LLC filed a First Amendment complaint against Google and attempted to include potential members of the class of plaintiffs in a class action.[7] The plaintiff's web site was removed from Google's index prior to the lawsuit and the amount of traffic to the site plummeted. On March 16, 2007 the United States District Court dismissed KinderStart's complaint without leave to amend and partially granted Google's motion for Rule 11 sanctions against KinderStart's attorney, requiring him to pay part of Google's legal expenses.
