If you must fix a link, be careful and methodical. Check it one last time to ensure that you fixed it correctly. Review your link text and the text surrounding your links one last time to make sure all links offer clear context as to where they will take the reader. If any possibility of misreading exists, consider rewording the affected sentences. Emphasize key words only, not entire phrases or sentences.
Abbreviations are easily misread and can confuse readers.
If you use abbreviations, apply only common ones and use them consistently. Be careful with acronyms. Sometimes acronyms can improve readability, but if overused or misused they create confusion. On first use on each page, spell out the term in full and then immediately display the equivalent acronym in parentheses. Re-identify the acronym on each page of the document.
