a.k.a. site rank, position
It means how relevant a Web page is to the keywords a user enters when doing an online search. It refers to where a Web site or Web page is ranked within search engine results. For example, if your Web site is an Internet dictionary, when a person queries "Internet dictionaries" in a search engine, your ranking indicates where in the search results your page is listed. You will hear it used like this: "My ranking on Google is within the top 5 results!"
