Frequently Asked Questions
Quick answers to common questions
What is the difference between APA and Chicago title case?+
APA capitalises all major words and words 4+ letters long. Chicago is similar but capitalises prepositions of 5+ letters and always capitalises the last word.
Which title case style should I use for blog posts?+
AP Style is standard for journalism and online publications. Chicago suits books and academic papers. For SEO, sentence case (first word + proper nouns only) can appear more natural in SERPs.
What words should not be capitalised in a title?+
Generally lowercase: Articles (a, an, the), coordinating conjunctions (and, but, or, nor), and short prepositions (at, by, for, in, of, on). Rules differ by style guide.
