Literature Review Gareth Rogan The text on the page itself is the next item the optimisation plan. It is here that the biggest change from traditional design appears. A site could be artistically brilliant, containing flashing images and graphical animations. However, to a search engine, this is not going to provide a higher ranking. The search engine uses a crawler (or robot) which will visit a site and send content back to the search engine. These robots cannot read flashing images or animations and all the artistic value of them will be wasted as no one may ever see them. The site should contain text in place of images etc where possible and that text should contain the keywords from the keyword list and the company name. The above are the main SEO techniques commonly employed in websites. These techniques are referred to as White Hat. There are other methods to improve the ranking of a site, referred to as Black Hat. Ledford, Jerri (2008) defines Black Hat as unethical SEO, and will not be considered outside of the boundaries of this thesis. These methods can result in websites being removed from the search engines if the methods are discovered on a site. 2.3 Google & PageRank Google uses system known as PageRank in order to determine the popularity of a site. This popularity score, along with traditional searching techniques are used to create the ranking for the search results page. PageRank is one of the foundations of the Google search engine. Langville, Amy N & Meyer Carl (2006) performed a details mathematical analysis of the Google search engine and PageRank. PageRank was originally patented 18
Literature Review Gareth Rogan in 1998 by Brin and Page, the founders of Google. PageRank works on the idea that a link is a recommendation or endorsement of the linked site. Langville et al (2006) note that PageRank scores form part of an enormous Markov Chain, and the mathematics behind how PageRank utilise Markov Theory. The exact details of these mathematics extend beyond the boundaries of this thesis, however the basic premise behind PageRank should allow us to use SEO techniques to improve our PageRank scoring. 19
