Social Proof

Last updated

Quick answer

Social proof is evidence, shown to a visitor, that other people have chosen, used, or approved the thing in front of them. Reviews, star ratings, customer logos, "1,200 teams use this," and a named testimonial are social proof.

Key takeaways

  • Social proof is other people's behavior or approval, shown to the visitor who has not decided yet.
  • Reviews, ratings, logos, usage counts, and testimonials are examples. A slogan about your own product is not.
  • Where to place it, and how those tests turn out, is covered by the placement post and the social-proof change type.

Definition

Social proof is evidence, shown to a visitor, that other people have chosen, used, or approved the thing in front of them. Reviews, star ratings, customer logos, "1,200 teams use this," and a named testimonial are social proof. A company's own slogan is not.

What Social Proof means in A/B testing

The idea is informational: the visitor borrows a decision other people already made. The evidence has to be about those other people. A badge you awarded yourself, or a stock photo of a crowd, does not meet the definition. In an experiment, social proof is the thing you add, remove, or move. The placement post is about position. The change-type page is about results. Neither is replaced by this definition.

Why Social Proof matters

On an unfamiliar page, other people's behavior is often the fastest signal of risk. Proof near a decision can answer "is this safe?" Proof in the wrong place, or proof that is thin, can also distract from the decision. Treating every logo strip as a guaranteed lift skips that distinction. Test the element. Do not assume the definition is a tactic.

Example of Social Proof

A product page shows a 4.6 rating from 800 reviews under the price, and a row of retailer logos under the description. Both are social proof. A headline that says "The best widget on earth" is the brand's claim, not proof. Moving the rating from the footer to the price is a placement test, which is the subject of the placement post, not a new definition.

How to use Social Proof

Use real evidence, name what it is evidence of, and put the experiment design in the placement post . Read outcomes on the social proof change type . Keep this page for the meaning of the term.

Common mistake

A common mistake is stuffing the page with every logo and review at once and calling that a social-proof strategy. Quantity is not the definition. Another is counting a press quote you wrote yourself as customer proof. The source has to be someone other than the seller.

FAQ

Is a star rating social proof if nobody has reviewed the product?

An empty or invented rating is not proof of other people's behavior. Social proof refers to evidence that exists: a real count, a real review, a real customer logo. Making one up is a false claim, not a stronger version of the same idea.

Where should I learn how to place it?

On the product-page placement post. This glossary page does not prescribe above-the-fold versus beside the price. The change-type page is where test outcomes for this kind of change are reported.

Does social proof always increase conversion?

No. It can reassure, or it can add clutter, or it can show weak ratings. That is why it is tested. The definition only says what the element is. The result depends on the proof and the page.
