Techopedia explains Google Juice
Developers and webmasters use all sorts of strategies to obtain Google juice. These include sophisticated SEO efforts, on-site affiliate marketing, back linking and content distribution. Now, experts are suggesting that the best ways to get Google juice are more profoundly linked to the content of the site and how it serves the readership. Webmasters and companies using websites for visibility are encouraged to pursue long-form content creation, build natural readership networks, and make a site more of a legitimate and credible source of thought leadership, rather than focusing on a lot of bells and whistles in order to get PageRank standings.
