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.
- CCuriosity
- Does the hook open a loop the reader needs to close?
- GGratification
- Will the reader feel something within the first three lines?
- OOriginality
- Have they read this exact opener 100 times before?
- VValue
- Is there a promise of useful information or insight?
- EEmotion
- 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.”
The full Typelab composer goes much deeper.
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 CGOVE, surfaces “ai tells” that make posts read robotic, and Boosts every published post via our curated engagement network.
