What is SERP?

SERP is an acronym for Search Engine Result Pages.  It commonly refers to a site's keyword ranking or position in a search engine and can be defined in terms of page and / or position.  For example, as of October 27, 2005, the Google rankings for http://www.root-beer.org for the keyword "root beer" are first page, first position, while the MSN rankings are first page, second position.

Having a high keyword ranking is the ultimate goal of search engine optimization (SEO), but achieving that goal can be very difficult, depending on the popularity of the keyword, the number of competing sites, and a large number of other factors, depending on the specific search engine.
