What CGOVE measures.
CGOVE is a 5-dimension framework for evaluating the first 1–3 lines of a LinkedIn post — the only part most viewers see before deciding to click “see more.” Each dimension scores 1 to 5.
Curiosity
Does the hook open a loop the reader needs to close?
Gratification
Will the reader feel something within the first three lines?
Originality
Have they read this exact opener a hundred times before?
Value
Is there a promise of useful information or insight?
Emotion
Does the hook trigger a feeling, not just a thought?
Total scores above 18/25 typically beat the LinkedIn algorithm’s initial-impression threshold; below 13/25 tend to scroll-past. 13–18 is “might work, depends on audience.”

Typelab scores every draft on this rubric.
CGOVE is one piece of what Typelab does inside the studio. The composer also generates the post body in your voice, runs hook variants through this same rubric, surfaces “AI tells” that make posts read robotic, and threads aspirational comments + voice check-ins into a single weekly rhythm.
