SEO technique through which authority is transferred from one page to another through internal links to improve positioning. This technique is usually explained using the simile of a glass of juice: imagine a web as a glass of juice (web) with a single hole (link) through which all the liquid comes out (authority). If instead of a single hole, more were made, the liquid - and the authority of the web - would be distributed through the different perforations.
This technique is based on the fact that Google positions the pages according to their authority, and that this is transferred from one page to another through links. Google interprets each incoming link to a website as a point of trust given to you by the page that hosts the link.
