What is Search Engine Optimization (SEO)?

SEO is the process by which someone makes to changes to an existing website so that the algorithm Google (or Bing, Yahoo, etc.) uses to rank websites pushes the website up in the rankings, say from the third page of results to the first page. There are many factors that can make a website jump up, or down, in the rankings. Probably the most important factor is quality content. Google doesn’t want websites with bad or misleading content to show up on the first page. People essentially use Google to find answers to their questions and Google does their best to have the first page of their search results be full of websites that do a great job of answering the question.
