Question: What is social proof?
- Evidence or an argument establishing or helping to establish a fact or the truth of a statement
- Being famous and having influence
- When someone sees other people like them doing something they're more likely to do the same and follow the crowd
Explanation
Social proof explains why people rely on the actions or opinions of similar others when deciding what to do. In HubSpot’s inbound marketing context, reviews, testimonials, and peer recommendations help build trust because they come from people outside the business. This matters during optimization because credible customer evidence can reduce hesitation before conversion. Strong social proof works best when it is relevant, authentic, and connected to the visitor’s decision.
Why the other options are incorrect
Evidence or argument is incorrect because it defines proof generally, not the behavioral influence created by other people’s actions.
Fame and influence is incorrect because popularity alone does not explain why people follow the behavior of similar others.
