You're seeing higher CPC on Pinterest Ads due to:
Smaller, niche audience with less ad inventory
Keyword-based bidding, where popular terms are more competitive
Low engagement creatives (Pinterest favors native-looking, high-save ads)
Poor optimization signals if your Pinterest tag or CAPI isn't set up properly
Less impulse-driven clicks compared to Meta or Google
Quick Fixes:
Broaden keywords
Use high-quality, native-style visuals
Try video or carousel Pins
Optimize with Pinterest Tag + event tracking
Higher CPC doesn’t always mean lower ROI — Pinterest often drives longer-term, high-intent buyers.
