3 Tips for Using Buyer Psychology in Your Marketing Strategy

Buyer psychology is the study of how and why people make purchasing decisions. It looks at the emotions, thought processes, and mental triggers that influence customers to choose one product over another, helping businesses create more effective marketing strategies.

Understanding how our customers think, feel, and behave takes the guesswork out of your marketing strategy. Buyer psychology lets you get inside your customers’ heads and create campaigns that:

• Grab attention
• Build trust
• Drive sales.

In this blog post, we’ll break down three simple but powerful buyer psychology theories—social proof, scarcity, and the reciprocity principle—to help you understand your audience. 

So, let’s crack open those skulls and get our zombies on! 

Why buyer psychology is essential for marketers

Understanding buyer psychology is a game-changer for marketers because it helps you connect with your audience on a deeper level and create campaigns that actually work. When you know what makes people tick—their emotions, decision-making habits, and mental shortcuts—you can craft messages that truly resonate with them. 

This not only makes your marketing more effective but also solves common business headaches, such as:

• Getting more engagement: If your emails or ads aren’t getting clicks, chances are they’re not grabbing attention in the right way. Understanding what excites and interests your audience helps you create content they actually want to engage with.
  
• Boosting conversion rates: Even a great offer can fall flat if it doesn’t tap into how people make decisions. Using psychology, like social proof or a sense of urgency, helps nudge potential customers to take action.
  
• Building brand loyalty: If people buy from you once but don’t come back, they might not feel a real connection to your brand. Knowing what builds trust and keeps customers emotionally invested means they’ll stick around for the long run.
  

When you really understand your customers, your marketing feels more personal and relevant instead of just another sales pitch. Plus, you’ll see a much better return on investment (ROI). That’s where ScoreApp comes in. We help you get inside your customers’ minds so you can create smarter campaigns that drive real results.

3 top tips for applying buyer psychology in marketing

Now we know why buyer psychology is a game-changer, let’s get into the top tips for using it in your marketing. These three buyer psychology concepts will help you connect with your audience, drive action, and see real results. Yes, there are real-world examples to prove it! 

1. Leverage social proof

Despite what people say about making independent choices, we’re all influenced by what others are doing. Research into how social proof works shows that we tend to follow the crowd, especially when we’re unsure about a decision. 

According to Cialdini, the principle of social proof states: “We determine what is correct by finding out what other people think is correct … We view an action as correct in a given situation to the degree that we see others performing it.”

And in the summary of his chapter on social proof, he says: “The principle of social proof can be used to stimulate a person’s compliance with a request by communicating that many other individuals (the more, the better) are or have been complying with it. Therefore, simply pointing to the popularity of an item elevates its importance.” 

(From: Influence: The Psychology of Persuasion by Robert B. Cialdini.)

In marketing, this means that showing popularity, credibility, and trust can have a huge impact on customer behavior.

Think about it. People want to buy from brands that others are already raving about. If a product is a bestseller, has glowing reviews, or is being talked about on social media, it immediately feels more desirable. That’s why businesses that highlight social proof see stronger engagement and conversions.

How can you use social proof to stand out?

To leverage social proof effectively, marketers need to showcase what makes their brand stand out. What’s your claim to fame? Are you the market leader? Do you have the most sales? The biggest growth? Maybe your product has thousands of five-star reviews? These details help remove doubt and build confidence in potential buyers.

Here are a few of the ways you can build trust and credibility through social proof:

• Reviews and testimonials: Genuine customer feedback reassures new buyers that your product or service delivers on its promises.
  
• User-generated content: Seeing real people use and love your brand creates an authentic buzz that feels more relatable than traditional ads.
  
• Sales milestones: Sharing how many products you’ve sold or how fast you’re growing signals that people trust your brand.

Real-world example: Chipotle and Wonderskin’s viral success

A great example of social proof in action is Chipotle’s unexpected collaboration with the cosmetics brand Wonderskin. They launched a limited-edition ‘burrito-proof’ lip stain called ‘Lipotle’—a fun, playful idea that quickly took off on social media. People loved the creativity, and the buzz led to a surge in demand, with customers eager to try it just because it was trending. Just after the launch, they reported sales of 1 every 15 seconds on TikTok! 

This shows the power of leveraging social influence. When people see others excited about a product, they naturally want to be part of the experience. By tapping into trends, partnerships, and social proof, you can create marketing campaigns that get people talking—and buying.

2. Use scarcity bias: Why limited availability drives action 

Scarcity bias is the psychological principle that makes us want something more when we think it’s in short supply. When a product is exclusive, has limited stock, or is only available for a short time, it suddenly feels more valuable. 

Brian Wansink’s research investigating sales of on-offer soup is still cited by experts in buyer psychology, even though it was done in 1998. This is because the research was done in real supermarkets, with real consumers—and he was Professor of Marketing at Cornell University! He tested sales with different numbers of cans each customer could buy, even though the sale price stayed the same. Spoiler alert—it did! The average number of cans per customer increased when there was a limit on how many were allowed. 

This is because our brains associate scarcity with high demand and rarity, making us eager to act before we miss out. Think major FOMO (fear of missing out)!

For marketers, this is a powerful tool. Creating a sense of urgency pushes customers to make decisions faster, reducing hesitation and increasing conversions. After all, nobody wants to be the person who waited too long and lost out! 

How you can use scarcity to drive sales

Brands across all industries use scarcity bias to boost engagement and sales. Here’s how you can apply it effectively:

• Limited-time offers: When deals or discounts have a countdown, people are more likely to buy on the spot rather than risk missing out.
  
• Exclusive access: VIP or members-only waitlists and products make customers feel special and encourage them to act quickly.
  
• Low-stock alerts: Highlighting “only a few left” or “selling fast” creates FOMO, so people are more likely to purchase.
  
• Seasonal or one-off products: Limited-edition releases generate excitement and urgency, making people more eager to buy.
  

Using these tactics, businesses can turn casual browsers into paying customers by triggering their natural instinct to act fast before it’s too late.

Real-world example: Amazon’s Prime Day frenzy

A perfect example of scarcity bias in action is Amazon’s Prime Day. This annual sales event is packed with time-limited deals available exclusively to Prime members. Because shoppers know the discounts won’t last—and that popular, best-value items sell out fast—it creates a massive surge in urgency-driven purchases.

Amazon expertly fuels this with countdown timers, ‘lightning deals,’ and real-time stock updates, making people feel they need to act immediately. The result? Huge sales spikes and record-breaking revenue. By leveraging scarcity bias, Amazon turns a short-term event into one of the biggest shopping days of the year.

3. Apply the reciprocity principle: Give value to get value

The reciprocity principle is simple: When someone gives us something, we naturally feel the need to give something back. It’s just how our brains work! Whether it’s a freebie, a favor, or even helpful advice, we’re wired to want to return the gesture.

For businesses, this means offering a little something extra. That can be a useful resource, a small gift, or an exclusive experience. It’s the giving that builds connections to your brand. 

And when people feel like they’ve already received value from you, they’re far more likely to engage, buy, or recommend your business to others.

How you can use the reciprocity principle to win customers

Smart brands use this principle to build relationships, create goodwill, and turn potential customers into loyal ones. Here’s how you can do the same:

• Give away something of value to your customers: There are so many options here: a free trial, book, video mini-course, webinar, sample product. Giving a free gift first makes people more likely to buy from you later. 

• Add a delightfully human surprise: We’re not talking romcom grand gestures here! But a little unexpected bonus, that’s clearly from one human to another, has more power than you think. Like a handwritten note, a packet of sweets in every parcel, or an exclusive discount ‘so they can buy themselves something, too’—inexpensive, genuine, and not being sent with the instruction to ‘post about how delighted you are.’ (But if they decide to do that themselves, we’re not exactly disappointed!)
  
• Share genuinely helpful content: Free knowledge (blog posts, guides, or how-to videos) that answers real customer pain points is always super-valuable. It builds trust, positions you as the go-to expert, and makes people more likely to check out your paid offers.
  

By giving before asking, you create a sense of goodwill that makes customers more likely to take action—whether that’s making a purchase, leaving a review, or recommending you to others.

Real-world example: Free trials that hook customers

One of the best examples of reciprocity in action? Free trials in the software world—we all know them. Brands such as Spotify, Netflix, and Adobe let you try their premium services for free before asking for a commitment. And it works—because once people experience the value, they don’t want to give it up!

By offering something useful upfront with no strings attached, these companies create a feeling of ‘I’ve already gotten something from them, so subscribing makes sense.’ It’s a simple but powerful way to turn curious browsers into long-term customers.
