The tags view is what screen readers and other assistive technologies use to deliver a high-quality navigation and reading experience to users with disabilities.

The content view is based on the physical order of objects within the PDF's content stream and may be displayed by software that does not fully support the tags view, such as the Reflow feature in Adobe's Reader.
