Search Engine Optimization 101 - Page Rank
The whole point of Search Engine Optimization, or SEO, is to improve your web site’s ranking; that is to move it up in the list of search results so that it is as close as possible to the top. Many users will look no farther than the first page of search results and some will only look at the first two or three. Therefore, the higher you rank the higher your number of web site visitors.
Search engines like Google, Microsoft and Yahoo use very sophisticated algorithms to rank web sites. The most famous algorithm is Google’s PageRank. The name PageRank is a Google trademark and the process is patented by Stanford University where it was developed by Google founders Sergei Brin and Larry Page in their paper, The Anatomy of a Large-Scale Hypertextual Web Search Engine.
In a nutshell, PageRank assigns a value to each page based on the other pages on the internet which link to that page. A link to your page by a higher valued page will increase the ranking of your page. In other words, it’s not just what you know but who you know. The idea is that your page has more credibility if it is referenced by other credible sites, especially those sites which are relevant to the keywords used in a search.
Search Engine Optimization 101 - Getting Indexed
Search Engine Optimization or SEO is the process of improving the use of keywords on your web site in order to increase the number of visitors from web searches using those keywords and phrases.
The term SEO is used when referring to “organic” web searches as opposed to paid web search advertising. Organic search results are based on a combination of the actual content of your web site along with links to your web site from other web sites. Search engines like Google and Yahoo use sophisticated algorithms to rank the popularity and relevance of web sites based on the content and links. Keywords are a very important part of this equation.
Search engines like Google, Microsoft and Yahoo use computer programs called robots or crawlers that go through the internet page by page, analyzing and storing the data found on each page and then following the links from that page to other pages. Once a page is store in the database it is said to be “indexed”. Your web site will be eventually be added to the search engine databases if a link to your site is found on another site that is already indexed.
Another way to get your web site indexed is to submit it to the Open Directory Project or by creating a Google Webmaster Tools account and adding your site. Yahoo also offers paid directory submissions.
