When we don't know something, we look at what others did. A restaurant full of people seems better than an empty one. An account with 10,000 followers seems more credible than one with 100.
Types of social proof online
- Follower and subscriber counts
- Likes, views and comments
- Reviews and ratings
- Media mentions and blue ticks
Use it honestly
Social proof gets people to look. Your product has to keep them. Use follower services to remove the "empty restaurant" problem, not to mislead people about what you sell.
