Like, what words to capitalize or not capitalize in the headline. To apply the right format you would come across several styles of formatting which would lead to more confusion.

There are several styles of title and headline capitalization that different publications use. For example, the AP Style is generally used by news organizations, the Chicago Style is more comprehensive for in-depth writing, and the MLA style is used for academic papers. Mostly there are basic general rules followed throughout all the publications but with minor changes between them. But if you're a professional in your field and you want your headline to be perfect, it's important to understand these differences and apply the formats accordingly.

Let’s understand more about different styles of headlines capitalization formats, so you can quickly write one up. There are four major title capitalization styles. These are:

AP Style

AP (Associated Press) Style is the most preferred writing style for journalists and news media organizations. AP Style is designed to ensure uniform writing and ease of understanding across different platforms.

Rules:

• Capitalize only the first word of your headline and all proper nouns or abbreviations; all other words should be lowercase (e.g. “The people making North Dakota’s future bright”).

• Use numerals for all numbers (e.g. “3 ways to write headlines” as opposed to “Three ways to write headlines”).

• Use single quotes for quotation marks in headlines (e.g. “Why Joe said ‘no’”).

• Use abbreviations only for well-known organizations, like the FBI, NASA, and FIFA. Abbreviations can be applied to people’s formal titles, such as political and medical titles, like CEO or PhD.

For example:

APA Style

APA (American Psychological Association) style is mainly used for scholarly articles in the behavioral and social sciences. Title case is recommended in APA Style for in-text titles, all heading levels, paper headlines, periodical titles, figure titles, and table titles. Format used in APA style act as a solid separator between text and the most important words, so they catch the reader’s eye as they are scrolling through content.

• Lowercase the articles the, a, and an.

• Lowercase prepositions, regardless of length, except when they are used adverbially or adjectivally (up in Look Up, down in Turn Down, on in The On Button, to in Come To, etc.) or when they compose part of a Latin expression used adjectivally or adverbially (De Facto, In Vitro, etc.).
