What is a Social Proof?
Social proof is the use of reviews, testimonials, user-generated content, and other indicators of customer behavior to build trust and influence purchase decisions. In ecommerce, it reassures shoppers that others have purchased and enjoyed the product.
Why Social Proof matters?
Customers are more likely to trust peer feedback than brand claims. Displaying social proof can reduce perceived risk, boost credibility, and increase conversion rates. It helps bridge the trust gap for first-time buyers and encourages hesitant shoppers to take action.
How Social Proof works?
Social proof can take the form of star ratings, written reviews, influencer endorsements, customer photos, purchase counters, or case studies. Ecommerce stores often place social proof near CTAs, on product pages, and in marketing emails.
Example in ecommerce
A home décor brand adds customer review snippets to product thumbnails on category pages. Click-through to product pages increases by 9 percent and conversion rates improve for products with higher ratings.
Common mix-ups
Social proof is not limited to written reviews; it includes any evidence that others value the product, such as “X people are viewing this now” messages.
Best practices
- Feature reviews and ratings prominently.
- Use authentic customer photos where possible.
- Highlight total review counts for credibility.
- Include social proof in retargeting ads.
- Keep reviews updated to avoid stale impressions.
Industry benchmarks
- Products with at least 50 reviews often convert 4 to 5 percent higher than those without.
