Social Proof
What is ?
Social proof in advertising refers to the visible engagement signals on your ads (likes, comments, shares, and reactions) that demonstrate other people have interacted with and validated your content. High social proof increases trust and credibility, making new viewers more likely to engage and convert. Preserving social proof through post ID duplication is a key optimization strategy.
Example
Your ad has accumulated 2,500 likes, 180 comments, and 95 shares over 4 weeks. When you need new targeting, you duplicate the ad using the same post ID instead of creating a new ad. The new ad set inherits all 2,500 likes and engagement, performing 25% better than a fresh ad with zero social proof.
Industry Benchmarks

| Low Social Proof | < 50 reactions | Minimal trust signal |
