9 Brilliant Examples of Websites Using Social Proof to Increase Conversions

This post provides nine visual and brilliant examples of how digital marketers use “social proof” on some of our favorite websites to increase followers, purchases, sign ups, email subscriptions and conversions. If utilized the correct way, this marketing tactic can be a very effective digital marketing strategy. When you’re done reading this post please share any brilliant ways you’ve seen digital marketers use social proof to influence users.

What is Social Proof?

Social proof is a psychological phenomenon where a person looks to the actions of others as assurance (or proof) that the decision they intend to make is the correct one.

Social proof is also 1 of the 6 key principles of influence, as researched by Robert Cialdini for his book titled, Influence: The Psychology of Persuasion. When discussing social proof, he gave a very interesting example of how social proof influences people. In an experiment one or more people would look into the sky, and other bystanders who saw this looked up into the sky as well. This reaction occurs in many scenarios, and of course it happens online. We look for social proof before we purchase, subscribe, or follow.

I recently experienced social proof offline with my wife when visiting a new outlet mall in the the Chicago-land area. We attempted to walk into a Tory Burch (no clue who that is) store, but we were quickly stopped and told to wait in a line of about 10 people before we could enter. As I looked into the store I noticed only about 15 people were actually in the store. It quickly dawned on me that this was a tactic of social proof. Tory Burch was attempting to influence bystanders by creating a line of people outside the door. Being the savvy marketer I am, I refused to wait in line knowing that I was being psychologically toyed with. However, as a digital marketer I must admit that I am some what of a hypocrite because I not only envy social proof tactics online but utilize them as well.

Types of Social Proof Online:

  • Displaying # of downloads
  • Displaying the # of purchases
  • Displaying the # of subscribers
  • Displaying your # of followers
  • Case studies
  • Testimonials
  • Reviews
  • Showing # of views
  • Showing # of comments or engagements
  • Displaying customer logos
  • Share buttons (that display number of shares)

If you’re thinking of utilizing social proof as a digital marketing strategy, I’ve got good news and bad news. The good news is that it should be very easy to display an automated or manual number on your site to help sell whatever you’re selling. The bad news is that you may have to wait until you get your numbers up. Five subscribers are impressive  but 5,000 subscriber are very impressive.
