This opportunity is utilized a number of parties to offer search engine optimization services for companies that have a base of business on the internet.According to Danny Sullivan, search engine optimization is a term first used on July 26, 1997 by a spam message posted on Usenet. At that time the search engine algorithms are too complex yet so easy to manipulate.Initial version of the search algorithm is based entirely on information provided by the webmaster via the meta tag in html code on their web site. Meta tags provide information about the content contained on a web page with a series of keywords (keyword). Most webmasters do manipulation by writing the keyword that does not correspond to the real site's content, so the search engines the wrong place and rank sites. This causes search results to be inaccurate and cause losses to both search engines and for Internet users expect relevant and quality information.Larry Page and Sergey Brin, two Ph.D. students at Stanford University computer science, trying to overcome these problems by building BackRub, a simple search engine that relies on mathematical calculations to rank web pages. Algorithm, called PageRank, is a complex mathematical function is a combination between the calculation of the number of links that point to a web page with an analysis of the quality of each link.Based on the principle of PageRank, can generally be said that the web pages that get high rankings are a lot of web pages linked by other web pages. PageRank value will be higher if a web page that led to him also have a high quality. The value of a high-quality links from sites like Yahoo! or DMOZ can be valued higher than the combined value of one hundred links from low quality websites.BackRub is only a beginning. In 1998 Page and Brin founded Google, which is an advanced version of BackRub. In a short time Google acquired a reputation and public trust of Internet users because it successfully provides quality search results (not manipulated), fast, and relevant. PageRank then be a good standard for other search engines as well as for webmasters who try to obtain its website PageRank values as high as possible so that the highest position in the search results.Webmasters and search enginesSince 1997 the search engine companies recognize that some of the [webmaster] (website manager) did everything to be indexed at the top of search results, including in ways that manipulative and illegal. Infoseek, one of the first generation search engines, make improvements in their algorithms to prevent manipulation of the "meta tags" that are not relevant.However, in some ways the search engines are also aware of significant economic value of the ranking of search results, and they sometimes have vested interests of the SEO company's activities. Some search engine companies to send representatives or be a guest at events held regularly SEO community.The big search engines like Google and Yahoo! to provide programs and guidance that enables webmasters to optimize their site to be indexed properly. Google provides Webmaster Tool application (you must have a Google account in order to see this tool) and introduced a standard XML-based sitemap them, whereas the Yahoo! Site Explorer provides a program (also need to log in with your Yahoo! account) which allows webmasters to register the URL site, check the number on their web pages that have been indexed in the Yahoo! database, and view the information of incoming links. However, search engines do not tolerate SEO methods are manipulative and justifies any means.Ethics and legalityPageRank system, although implementing a complex algorithm, the latter also no longer fully able to deal with the tricks and manipulation. Some webmasters and SEO practitioners have developed several methods that take advantage of how the PageRank of web pages that their clients are at the first ranking of search results. Google has officially banned the use of some illegal techniques such as link farming, doorway pages, keyword stuffing, and auto-generated pages or pages scraper. Sites or services that remain menggunakanannya threatened SEO will be deleted from the search index.The threat of Google and other search engines is not just bluster. Some SEO services companies and their clients who do not heed the ban was to receive a serious penalty for their illegal actions. In 2005, Matt Cutts of Google says that the URL of an SEO firm called Traffic Power and their clients have been removed from the Google index for using illegal SEO techniques. Another famous case was in February 2006 when Google remove a website of BMW and Ricoh Germany from the list because of proven SEO methods are manipulative. BMW and Ricoh immediately apologized to Google and improve their sites. Google then re-enter their web site into the search index. But the scandal still leaves a bad image and embarrassing for both companies.Under the official guidelines of search engines, SEO is not an illegal technique performed by following along the ethics and rules. This is to ensure each website to obtain equal opportunities in search, and ranking is done by an objective, where the greatest role in determining the ranking of a web page is the quality and benefits for Internet users.Leading figures SEOIn addition to the Google founders Larry Page and Sergey Brin, some people become a respected figure and a reference opinion about search engines and SEO business.Danny SullivanFormer LA Times journalist who founded the Web site Search Engine Watch highlights active business development and search engine technology. Now he is actively writing and reportage at Search Engine Land.Matt CuttsProgrammer and former employees of the NSA (National Security Agency) United States who joined Google in 2001 and currently heads the team of Google's spam prevention. In addition to being an employee of Google, Matt Cutts is a leading blogger. The articles in his blog a reference SEO practitioners from all over the world, because his blog is often the first source of any information on the development of Google's search technology. Matt Cutts is often regarded as the unofficial spokesman for Google.

Vannesa known among webmasters as a drafter, and programmer who headed the project Google Webmaster Central.International marketing strategySEO service business and growing rapidly along with the growth of the web, which led to a site must try harder to be addressed more easily found among the millions of visitors to address the other sites from around the world who become competitors. The search engine is the main entrance, because Internet users are no longer able to memorize millions of websites, and instead they rely on search results from Google, Yahoo!, Bing, and other search engines.Being at the top or at least the first page of search results for specific subjects provide a double advantage for the company marketing via the internet:
Opportunities prospective customers visiting their web sites become larger. This can lead to increased conversion rate of regular visitors into buyers.
Being ranked first on the search results give a good image and reputation for a site in the eyes of visitors.Search engines generally do not seek profit directly from organic search results. Operating revenues they earned from the ads displayed at the top or side of the organic search results. The less successful companies implement SEO strategies so that the site address is not in the top position in organic search results can still get visitors by advertising on the search engines.On Google, advertisers can be done through Google AdWords. Google AdWords establishes a mechanism to pay per click or pay per click, meaning that for every ad clicked by visitors, advertisers will be charged, the amount of which varies depending on the bidding process (bidding) keywords by advertisers.
