SEO - Search Engine Optimization

What is SEO?

SEO is the act of modifying a website to increase its ranking in organic (vs paid), crawler-based listings of various search engines.

How do organic search listings work?
  • A spider or crawler which is a component of a SE gathers listings by automatically "crawling" the web
  • The spider follows links to web pages, makes copies of the pages and stores them in the SE’s index
  • Based on this data, the SE then indexes the pages and ranks the websites
  • Major SEs that index pages using spiders: Google, Yahoo, Bing, AltaVista, AOL, Lycos
