All books have headers and/or footers that indicate the section or chapter name to help orient the reader as to what section they are in. In the case of a presentation, use the footer area to add your corporate confidentiality or copyright information which discourages people from spreading your secrets.
Having your company’s great thinking floating around without copyright information puts you at risk for idea theft.
Using headers and footers in a presentation is even more important than in a book. Because presentations can be copied, pasted, and spread, you want your copyrighted or confidential information to travel with your slide pages.
By inserting a “Header and Footer” in PowerPoint® presentations, you can add a footer to the slide view and header to the notes view.
The header and footer setting is also where you add page numbers. Projected presentations don’t usually show page numbers, but they’re imperative for a presentation you pass around to be read, in other words, for slidedocs.
Page numbers help users navigate the Table Of Contents in a slidedoc. During meetings where you’re discussing the presentation, reference page numbers so people can quickly turn to the appropriate section.
