Herd instinct and online sales: How buyers follow the crowd and how to take advantage of it

Have you ever stood in front of a crowded café and decided to go there, even though the one across the street is almost empty? This unconscious decision is a great example of the bandwagon effect, also known as herd instinct. It refers to a situation where individuals do something just because the majority is doing it.

In online stores, herd instinct can significantly boost sales if used wisely. In this post, we will explore how to recognize it, how to use it, and how to design your online store so that customers are eager to “jump on your bandwagon.”

Why herd instinct works

Customers often cannot try a product before buying it. Therefore, they look for signs that the product is verified, popular, or of good quality. Some reasons why it works:

  • Social proof: if many people are buying a product, it seems to be good.
  • Fear of missing out: if something is rare or quickly selling out, we feel compelled to act.
  • Visibility and repetition: the more someone sees your brand or product, the more likely they are to want it.
  • Desire for exclusivity: some customers seek unique products that are not for everyone and feel special if they acquire a limited edition.

It is important to know that the bandwagon is not manipulation but a tool to help customers make decisions and create a sense of trust and popularity.

How the bandwagon affects the buying journey

In an online store, the bandwagon can affect all steps:

  1. Product viewing: If they see that a product is popular or many people are viewing it, they are more likely to click and view it.
  2. Adding to cart: If there are positive reviews, user images, or sales alerts, the likelihood of adding the product to the cart is higher.
  3. Purchase completion: Limited stock or a message that the product is in high demand reduces the chance of abandoning the purchase.
  4. Sharing and re-exposure: Satisfied customers share the product with others, increasing visibility and continuing the bandwagon cycle.

Practical steps for your online store

1. Show that the product is in demand

Customers like to see that products are not “forgotten on the shelf.” Examples:

  • “Currently, 5 people are viewing this product.”
  • “48 pieces sold in the last 24 hours.”
  • “Only 2 pieces left in stock.”
  • If the product is sold out, offer the option to sign up for a notification when it is back in stock.

Why it works: customers see that many people are using the product and are more easily persuaded to buy.

2. Build credibility with customer photos and reviews

Reviews are important, but user photos and videos have an even greater effect:

  • Show customer images with the product.
  • Share short video testimonials from satisfied customers.
  • If you have results that can be shown (e.g., before and after for cosmetics or weight loss), highlight them.
  • Show the number of followers on social media – people prefer to buy from brands with an active community.

Example: Slovenian cosmetic brands often share user videos showing progress before and after using the products. This is not just an advertisement but proof that the product works.

3. Create a sense of exclusivity

Some customers want to be part of a special group:

  • Limited edition products.
  • VIP lists for early access to new products.
  • Special personalized options, such as engravings or unique designs.

Example: Some outlet stores provide access to special collections only to certain loyalty club members. These members receive invitations to exclusive events where limited stock of renowned brand products is available. Knowing that the offer is not available to everyone and that stocks quickly run out, customers feel a strong desire to seize the opportunity – even if they would not necessarily buy otherwise.

4. Be visible on multiple channels

The more often a potential customer sees your brand or product, the stronger the bandwagon effect.

  • Post on Instagram, Facebook, TikTok, and email.
  • Show user images, reviews, and product popularity wherever your audience is.
  • Repetition of the message builds trust and increases the desire to purchase.

5. Combine the crowd and exclusivity

A true master of the bandwagon effect knows that both types of customers need to be satisfied:

  • Those who want to follow the crowd and choose popular products.
  • Those who seek exclusivity and want to have something special.

Example: offer a limited edition of products used by many people, while the number of pieces is limited. This way, you gain a sense of the crowd and exclusivity at the same time.

The herd instinct is a powerful tool that online retailers can use to help customers make decisions, increase trust, and boost sales.

If you:

  1. show that the product is in demand,
  2. build credibility with user images and reviews,
  3. create a sense of exclusivity,
  4. are visible on multiple channels,
  5. combine the crowd and exclusivity,

…you will create a “wagon” that customers will want to jump on.
