Tracking is the space between all the letters throughout your text. Adjusting tracking to style titles and headlines can make them stand out, but it’s unnecessary in larger blocks of text since most typefaces set their tracking based on body copy.

Positive tracking can create more contrast and increase legibility when done properly. You can also use negative tracking, making letters closer together. Small adjustments can add a stylized effect (and allow you to fit more text on a single line), but it’s easy to overdo it and make text harder to read.
