findability : the rich get richer

With the google multi algorithmic approach combining, text metadata and popularity measures, the more people link to a site the higher it is in the search results and thus the more likely it is to be linked to.
People often place findability higher than content quality, if something is easily accessible, they will take what is easy to find and often give up looking further, even if further searches could have given them better results.
Networks – the greater the visibility the more likelihood of being found which further increases visibility.

    'Tagged PDF is a stylized use of PDF that allows reliable recovery of text, graphics, and images in PDF documents, with no ambiguity about the contents or the ordering of the contents. A Tagged PDF file is page oriented. Each page of a Tagged PDF document contains the text, graphics, and images in reading order, as determined by the authoring application. A Tagged PDF is a Logical Structured PDF. Logical Structure is used to carry information necessary to support tagging for access and content extraction, as well as styling properties needed for access, reflow, and content extraction. It also provides the identification of the article flows in the cross-page environment for access and content extraction.'
