Improper capitalization in DKI can negatively affect ad performance in several ways:
1. Ad Disapproval & Compliance Issues
Google restricts excessive capitalization (e.g., "BUY NOW!!!").
If DKI inserts keywords in all caps, the ad may be disapproved.
2. Poor Readability & User Experience
Inconsistent capitalization (e.g., "Best Shoes for WOMEN") appears unprofessional.
Poor formatting can reduce trust and lower CTR (Click-Through Rate).
3. Negative Brand Perception & Engagement Drop
