Correct Reading Order

Your document's reading order is the order in which a screen reader will read its elements. While Adobe Acrobat XI will attempt to establish a reading order automatically as you tag elements in your document, the order it creates is often incorrect. You must check and / or correct your document’s reading order manually after you have tagged all of your document’s elements. Do this in the Tags panel.

Tag Decorative Images

Decorative elements (called "Artifacts" in Adobe’s documentation) are elements that should be placed in the background of your document so that they are not read by screen readers. Some example may be borders or decorative bars to separate sections. Some images are put on a page for "looks" and do not have any meaning to the content.

Add Alternate Text to Images

Alternate text, or "alt text", provide a way for screen-reader programs to "read" non-text information in your document. For example, if you wish include a photograph of a sunset in your document, the image should include an alt-text that states, “Sunset.” Likewise, if you include images of words that are not digitally-readable text (e.g.. a photograph of a stop sign, clipart showing words in thought-bubbles, etc.), the words in these images should also be placed in alt-text.
