What is title case?
Title case is a capitalization style where the principal words in a title or headline are capitalized, while minor words like articles, short prepositions, and conjunctions are usually left lowercase. Different style guides (AP, Chicago, MLA, NY Times) disagree on exactly which words count as "minor" and whether word length matters — which is why the same headline can look slightly different across styles.

Title case for Google Ads headlines
Google Ads RSA headlines have a hard limit of 30 characters — anything longer gets rejected at save time, not just truncated. Title case can make headlines feel more like a brand or offer ("Free Shipping On All Orders") while sentence case can feel more conversational and native ("Free shipping on all orders"). Test both — Google's machine learning will favor whichever combination performs better, but starting with a consistent casing convention makes your account easier to audit.
FAQ
What is the difference between AP style and Chicago style title case?
AP style only lowercases short minor words (under 4 letters) like 'a', 'the', 'and', 'to' — words of 4+ letters are always capitalized, even prepositions like 'With' or 'From'. Chicago and MLA style lowercase a broader list of minor words (articles, conjunctions, prepositions) regardless of length, unless they are the first or last word of the title.
What is the character limit for Google Ads RSA headlines?
Each Responsive Search Ad headline has a maximum of 30 characters, including spaces and punctuation. You can add up to 15 headlines per ad, and Google Ads will reject any headline that exceeds 30 characters when you try to save it.
Should I capitalize every word in my Google Ads headlines?
There's no single right answer — both title case and sentence case are common in high-performing ads. Title case can make a headline look more like a proper offer or brand name, while sentence case often reads more naturally. The best approach is to test both styles and let Google Ads' performance data guide your decision.
Does title case affect Google Ads Quality Score?
Capitalization style itself does not directly affect Quality Score. Quality Score is driven by expected click-through rate, ad relevance, and landing page experience. However, consistent, readable formatting can indirectly improve CTR, which is one of the inputs to Quality Score.
Why do AP, Chicago, MLA, and NY Times styles produce different results for the same text?
Each style guide defines its own list of 'minor' words that stay lowercase and its own rules for word length. For example, AP capitalizes any word of 4+ letters regardless of part of speech, while Chicago and MLA always lowercase common prepositions and conjunctions like 'with', 'from', or 'into' unless they start or end the title.
