Talking about
SEO is not complete if we do not know origin of
SEO. The term "
search engine optimization" was first used on 26 July 1997 by a spam message posted on Usenet. In the period of the search engine algorithms is not too complex so easily manipulated with the goal to appear on the first page of search engines if the first thankfulness.
Initially, the search engine's search algorithm is based on information provided by the webmaster through the meta tags in html code their web sites. This is the meta tag that provides information about the content on a web page with a series of keywords (keyword). Then the webmaster how to manipulate the write keyword is not in accordance with the real site's content, so the search engines and create a place ranking sites. This causes search results to be inaccurate and cause losses to both search engines and for users who expect the relevant information and quality.
Larry Page and Sergey Brin, two doctoral students in computer science from Stanford University, tried to overcome the problems with the build BackRub, a search engine that fully rely on mathematical algorithms to rank web pages. These algorithms, called PageRank, is a mathematical function of the value of a complex combination of calculation from the number of links that lead to a web page with the analysis on the weight of each link, with a scale of 1-10. Based on the principle of PageRank, in general, can be said that the web pages that have a high ranking web pages is that many in-links by another web page. PageRank value will also be high when the web page that lead to him also has a high ranking. So the value of a link from the site such as Yahoo! worth more than the combined value of one hundred links from a web site that is not known.
BackRub is just a fetus. In 1998 Page and Brin founded Google, which is the version of "adult" from BackRub. In a short period of time Google's reputation and gain trust from the public Internet because the user presents the successful results, which are relatively clean (not manipulated), fast, and relevant. PageRank directly into the system both for standard search engine for webmasters and others who work to make sure the website gain PageRank value possible so that the highest position on the search results.
SEO service business and growing rapidly in line with the growth of the web, which causes a web site must be "fought" tooth and nail so that the address easy to find customers among the millions of addresses of other sites from around the world who become competitors. Search engine is the main entrance, because internet users are no longer able (and do not want to) to memory addresses on a web site, and instead they rely on the index is created by the search engine.
