🔍 Verdict: Meta offers more granular rule customization and creative-level automation. Google leads in bidding strategy depth and cross-network delivery.

2. Cost Efficiency & ROI

Facebook Ads

Typically lower CPMs and CPCs, especially for B2C and DTC brands
Better for top-of-funnel prospecting and visual storytelling
More sensitive to creative fatigue; requires ongoing refresh

Google Ads

Stronger ROAS for high-intent traffic (e.g. search and shopping campaigns)
Higher CPCs in competitive keyword markets
Great for lead gen, B2B, and bottom-of-funnel conversion

🔍 Verdict: Meta is more efficient for discovery and creative-driven campaigns. Google shines in intent-based acquisition and direct response.

3. Targeting Capabilities

Remarketing lists for Search Ads (RLSA)

🔍 Verdict: Meta leads in behavioral and custom audience depth. Google excels at aligning search intent with ad delivery.

4. Reporting Capabilities

Facebook Ads

Clean breakdowns by creative, audience, placement, and objective
Real-time tracking of ROAS, CPA, CTR, and frequency
Conversion paths harder to attribute post-iOS14; relies on modeled conversions
