Google juice is jargon for the ability or power of a website to turn up in Google searches. A website that commonly turns up as the first or second entry in a variety of searches — especially for keywords that are not part of the site s name — can be said to have a lot of Google juice. It is frequently used by bloggers and webmasters. Google s PageRank system plays a large role in ranking hits for a given search. It works by counting how many times a site has been linked to and by the quality of those links — namely how many times the site that is linking has been linked to. In this way, sites with high Google rankings (i.e., lots of Google juice ) can offer to share or give Google juice to a less popular site. A link from a site with less Google juice can also be helpful in this regard to a lesser degree: there is less juice to give.
Google s 2005 April Fools Day hoax, the fictitious drink Google Gulp, was a take on the term Google juice.
