What Are Footnotes – How to Use Them Effectively

Mostly, it is recommended to use small numbers like 1, 2, 3 in footnotes. These numbers are added in the text, and the user can read related information in the notes present at the bottom of the page. Whereas symbols like * or + are only used when we have a few notes, which can be one or two. 

Most of the time, writers choose numbers that are easier to follow for readers especially if you want to link a lot of sources or facts.
