Also known as position, rank is the place a website occupies relative to the first listing on an Algorithmic Results page in response to a Keyword query. The first page displays Listings in the one through ten positions, the second page eleven through twenty, etc. Businesses trying to get their site into a top-ten rank will often employ a Professional Search Engine Optimization company. Consumer studies have shown that most search engine users click only on sites that occupy a top-ten rank.

A referrer is a web page containing a link to your web page, that delivered your visitor to your web page. For example, if Google’s search results (for example on a search for “britney spears”) contained a link to a page on your site and the user clicked on that link to go to your page, the result page is called a referrer.

Also known as Crawler or Spider, a robot is a search engine program that “crawls” the web, collecting data, following links, making copies of new and updated sites, and storing URLs in the search engine’s Index. This allows search engines to provide faster and more up-to-date listings.
Also known as robots exclusion protocol, Robots.txt is a text file stored in a site’s root directory that tells a search engine Crawler which site pages and sub-folders should not be included in the search engine Index. However, there is no guarantee that a Crawler will comply with this request. Robots.txt is an alternative to a Meta Robots Tag or password protection.
