Description - A brief description of the page. Search engine uses this description and shows it below the title of the website. The description should be contained within 160 characters.


Keywords - A series of keywords you deem relevant to the page in question. Do not repeat the keywords as you would only get 160 characters to list all of them.

Robots - An indication to search engine crawlers (robots or "bots") as to what they should do with the page.
