PDF tags are not only needed to give content a semantic meaning, but also to determine the logical reading order. In Acrobat, the order of the tags within the tag tree can be modified.
Move a tag in the tag tree
- In the navigation pane “Tags”, click on the tag which is in the wrong position and drag it to the right position.
- While holding down, a black line is displayed and marks where the tag is moved when you release it.
- If the small arrow of the line is on the far left, the tag will be moved below and on the same level as the tag displayed above.
- If the small arrow of the line is further to the right, the tag will be moved within the tag displayed above.
Navigating within the tag tree

Testing outside of Acrobat
By checking the tag tree in Acrobat, the logical reading order can be verified. Since this can be confusing and tedious, another tool should be used. The article “Check semantics and logical reading order” shows how this manual check can be done in a better way.
