> Do tags affect how the PDF is displayed visually in a browser?

Implementers of PDF viewers may use tags in any number of ways, including to influence visual display, drive navigation systems (such as zooming, or a joystick), move between form-field elements and more.

Example: one could use tags to represent a three-column document in a single column of text. Existing tools such as pdfGoHTML and VIP Reader provide precisely this capability.

Whether and how to use tagged PDF is a choice for each software developer.

To answer your specific question, I'm not aware of mobile browser software that makes use of tagged PDF at this time (but I would love to be corrected on this point!)
