Group Related Elements
Scattered elements are visually confusing. The reader's eye doesn't know where to settle, or which pieces of information are related to each other.
Organize your information into small, manageable chunks. If a headline and a subhead are related, put them together. If your address appears on the page, put it in a tight little block, and put some white space between that block and other elements.
Visually group related elements together, and the reader will take in each part as a unit as you intended.
The corollary principle is that unrelated information should be separated by white space, lines, and borders.
Take for example a flyer advertising a car for sale. The car's features can be listed close to each other in a bulleted list. Their proximity would indicate that they are related. But you wouldn't want to include your contact information in the same list. Instead, you'd group that information in a separate block, set off by white space from the features list.
