Complete Sentence Title
Whether the title is a grammatically complete sentence with a subject and verb, rather than a phrase or fragment. Complete sentences make a statement; fragments label or tease.
Complete sentences assert something — they make a claim the viewer can agree or disagree with. Fragments ('Infrastructure Bill Update') merely categorize. On YouTube, assertions drive more engagement because they take a position, which activates the viewer's desire to confirm or challenge.
