History SEO briefly:
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 is not too complex so easily manipulated. The initial version of the search algorithm is based entirely on the information provided by the webmaster via meta tags in the html code of their website. Meta tags provide information about the content that is contained on a web page with a set of keywords (keywords). Most webmasters do manipulation by writing down key words that do not correspond to the actual site content, so that search engines misplaced and rank those sites. This causes the search results to be inaccurate and have caused losses for both search engines as well as for Internet users who expect quality and relevant information.
SEO history at that time, Larry Page and Sergey Brin, two computer science doctoral student at Stanford University, trying to overcome these problems by building BackRub, a search engine that relies on simple mathematical calculations to rank web pages. The algorithm, which is called PageRank, a complex mathematical function is a combination of calculation of the number of links that point to a web page with the analysis of the quality of each link above.
Based on the working principle of PageRank, in general it can be said that web pages are obtaining a high ranking is that a lot of web pages linked to by other web pages. PageRank value will also be higher if the web page that leads him also having a high quality. The value of a high-quality links from sites such as 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 gained reputation and trust of the public Internet users for successfully serving quality search results (not manipulated), fast, and relevant. PageRank then became a good standard for other search engines as well as for webmasters who try to make the website gain PageRank score as high as possible so that the highest position in the search results.
