Google Juice

Google Juice (noun) is Internet slang for the invisible PageRank power juice that flows back and forth between links pointing to webpages and the webpages themselves.

A webpage can have very little Google Juice (meaning it doesn't rank high with Google due to links) or it can have a lot of Google Juice (meaning it ranks high on Google's Search Engine Results Page due to links).

If your webpage contains a link to a webpage with a lot of Google Juice (a really "juicy" page), your webpage will get a bit of "Reflected Google Juice." If your webpage has a lot of links pointing to it, it will have a lot of Google Juice of its own, and the links pointing to your webpage will be given some Reflected Google Juice by Google's search engine.
