What Is Title Case?
Title case capitalizes the main words in a headline while keeping short words like "a", "the" and "of" in lowercase. It is the standard style for book titles, news headlines and many blog post titles.
Sentence case, by contrast, capitalizes only the first word and proper nouns, just like a normal sentence. Both are correct. What matters is using one style consistently across your site.

Does Capitalization Affect SEO?
No. Google treats uppercase and lowercase the same for ranking. Capitalization does affect how your result looks, though, and a clean, consistent title can earn more clicks.
Avoid writing whole titles in capitals. They are harder to read and can look like spam. For more, see title tag optimization and heading structure best practices, and preview your title with the SERP snippet preview.
