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
