If you make that navigation similar to your site navigation, you'll even have some branding built-in.

Include Navigation in the PDF - While most readers include some way to see an overview of the PDF document if you include a clickable table of contents, forward and back buttons, and other navigation you'll have a PDF that is much easier to use.

Ask your parent or grandparent to read the document with the default font size if you're not sure if it's big enough. It's better to have your font size legible from the get-go. While it is possible to zoom in on PDF documents in many readers, not all users know how to do this.

Make the Font Legible - Unless you know that your core audience is kids under 18, you should make the font larger than your first impulse.

If the PDF is intended to be printed, then you can write for a print audience, but bear in mind that some people will still want to read your PDF online if only to save paper. And if the document is intended to be read in Acrobat Reader or some other online device, then the same rules for Web writing apply to your PDF.

Practice Good Web Writing in Your PDF Files - Just because the content is in a PDF doesn't mean you can forgo good writing.

If you don't optimize the images, the PDF will be much larger and thus slower to download. Optimize PDF Images - Just like with Web pages, PDFs that have images in them should use images that are optimized for the Web.Most browsers need to download the full PDF before they can render it, so anything larger will take a long time to download, and your readers might just hit the back button and leave rather than wait for it. If you're creating a PDF for your customers to read online you should make it small. Small PDFs are Good PDFs - Just because a PDF can be made of any Word document doesn't mean that it shouldn't follow the same rules of any other Web page or a downloadable file.
