What is SEO

Focuses on the natural, organic relevancy and ranking of content in search results

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

How do organic search listings work?

• A spider or crawler which is a component of a search engine gathers listings by automatically “crawling” the web. Refer to web diagram.
• The spider follows links to web pages, makes copies of the pages and stores them in the search engine’s index
• Based on this data, the SE then indexes the pages and ranks the websites
• Major search engine’s that index pages using spider ie Google, Bing Yahoo

  “Spiders read only text, nothing else”

How search engine’s obtain content

• Search Engines send “bots,” that spider the web.
• Crawls via hyperlinks
