Applying AIO Studies to Understand Heavy Users

Why do some brand advertisements feel like they are speaking directly to you, while others miss the mark completely? It is not magic, and it is not a coincidence. It is the result of a deep, data-driven understanding of who you are, what you do, and what you believe. For decades, marketers relied on basic information to find their customers: “We are looking for men, aged 30-45, with a household income of X.” This is called demographics. But there is a huge problem with this approach. You could have two men who are the exact same age, live in the same neighborhood, and earn the same salary, yet one spends his weekends hiking and is passionate about environmental causes, while the other is a homebody who loves video games and gourmet cooking. Would you try to sell them both the same product in the same way? Absolutely not. This is where marketers get smart. They go beyond *who* you are and dig into *how* you live. This deeper level of understanding is achieved through AIO studies, and they are the key to finding a company’s most valuable customer: the heavy user.

What exactly are AIOs? 🔗

AIO stands for Activities, Interests, and Opinions. These three dimensions are the core components of psychographics, a field of study that groups people based on their psychological attributes and lifestyles. Think of it this way: if demographics are a simple, black-and-white sketch of a person, AIOs are the full-color, high-definition painting. They give the person texture, personality, and motivation. Let’s break each one down.

A is for activities 🔗

This is all about how people spend their time and, by extension, their money. It is the “what they do” part of the equation. Activities are concrete, observable behaviors. This can include:

• Work: Their occupation and how they approach it.
• Hobbies: Do they play sports, build computers, or paint?
• Social Events: Do they frequent parties, concerts, or religious services?
• Vacation: How and where do they travel?
• Entertainment: What movies, shows, or sports do they watch?
• Shopping: Where do they shop, and how often?

Knowing these activities helps marketers place their products in the right context. For example, a person whose main activity is “running marathons” is a very different consumer than one whose main activity is “attending film festivals.”

I is for interests 🔗

Interests are what a person finds curious, engaging, or important. This is what captures their attention and passion. While an activity is what they *do*, an interest is what they *care* about, even if they are not actively doing it at that moment. Interests might include:

• Family: Their focus might be on their children’s education or family well-being.
• Home: They might be deeply interested in interior design or gardening.
• Fashion: They follow trends, designers, and style influencers.
• Food: They are a “foodie” who loves cooking, dining out, and exploring new cuisines.
• Technology: They are an early adopter who reads tech blogs and loves new gadgets.

Interests reveal a person’s priorities. A marketer can use this to align their brand’s message with a consumer’s core passions, creating a much stronger emotional connection.

O is for opinions 🔗

This is the most complex layer. Opinions are a person’s worldview, their beliefs, and their attitudes about… well, everything. This includes their views on social issues, politics, the economy, the environment, and even themselves. Opinions are the “why” behind their actions and interests. Examples include:

• Self-perception: Do they see themselves as a leader, a parent, an innovator, or a free spirit?
• Social Issues: What are their views on sustainability, equality, or community?
• Politics: Their political leanings can heavily influence their purchasing.
• Business: Do they trust large corporations? Do they prefer to “buy local”?
• Future: Are they optimistic or pessimistic about their future?

Understanding opinions helps a brand craft a message that resonates on a deep, ideological level. When a brand takes a stand that aligns with a consumer’s core opinions, it can build powerful, lasting loyalty.

Why marketers obsess over the “heavy user” 🔗

In the world of marketing, not all customers are created equal. There is a well-known concept called the Pareto Principle, or the 80/20 rule. In this context, it often means that a small percentage of your customers (say, 20%) is responsible for a huge percentage of your sales (say, 80%). These are the “heavy users.” They are the loyalists who buy your product frequently, spend the most money, and are often vocal advocates for your brand. It is far more efficient and profitable to keep these heavy users happy and engaged than it is to constantly try and acquire new, “light users” who may only buy once. The challenge, of course, is finding them. This is where the 80/20 rule meets AIO studies.

The 80/20 rule in action: the beer example 🔗

One of the most famous examples of identifying heavy users comes from the beer industry. A foundational study revealed a striking statistic: just 23% of beer drinkers accounted for 80% of all the beer sold. This was a massive “aha!” moment for marketers. Why waste millions of dollars on advertising campaigns aimed at the 77% of people who drink beer only occasionally? The smart money was on targeting that core 23% with laser focus. But who were they?

Demographics alone were not helpful. They were “men” of a certain age, but that was too broad. Marketers needed to know what made this 23% *different*. An AIO study would be the tool to find out. Do these heavy drinkers all watch the same sport? (Activity) Do they value camaraderie and tradition? (Interests) Do they see themselves as hardworking, “real” guys? (Opinions) By answering these questions, beer companies could stop running generic ads and start creating campaigns that spoke directly to the lifestyle and values of their most important customers. This insight is why so much beer advertising is linked to major sporting events and themes of friendship and relaxation after a long day’s work. They are not just selling beer; they are selling a product that fits perfectly into the heavy user’s life.

Case study: going beyond demographics with eye makeup 🔗

A classic case study in the power of AIOs was conducted by researchers William Wells and Douglas Tigert. They wanted to build a profile of the heavy user of eye cosmetics. As with any marketing research, they started with demographics.

What demographics told them 🔗

The demographic data was straightforward. The heavy user of eye makeup was easy to spot: she was a young, educated woman living in a major city. This is useful, but it is not actionable. Think about it. In cities like Mumbai, Delhi, or Bangalore, this description fits *millions* of women. How could a cosmetics company possibly target them effectively? Should they buy ads in every city newspaper? On every bus? This demographic profile is far too broad and expensive to target. It describes who she is, but not what she cares about.

What the AIO profile revealed 🔗

This is where Wells and Tigert’s AIO inventory changed the game. By asking questions about activities, interests, and opinions, they painted a vivid, specific, and surprising portrait of the heavy eye makeup user. They discovered that, compared to the general population, she was also:

• A heavy smoker.
• Prone to making long-distance phone calls (in an era when this was a significant, intentional expense).
• A “fantasizer” who dreamed of traveling the world.
• Someone who aspired to have a stylish, beautifully decorated home.

Suddenly, a blurry demographic snapshot becomes a sharp, clear photograph of a real person. This is not just a “young, educated woman.” This is a person who is likely social, possibly a bit of a risk-taker (smoking), and highly aspirational. She values connections (long-distance calls) and sees herself as worldly and sophisticated (travel fantasies, stylish home). She does not just use eye makeup to “look nice”; she uses it as a tool for self-expression, glamour, and to project the sophisticated image she has of herself. This focus on psychographics over demographics gives marketers a precise roadmap. You are no longer selling “makeup.” You are selling *glamour*, *sophistication*, and *a ticket to a more exciting life*. You would place your ads in high-fashion magazines and design them to be dramatic and aspirational, not just practical.

Case study: the profile of the heavy credit card user 🔗

Another foundational example of AIO application comes from marketing pioneer Joseph Plummer, who studied the heavy user of bank credit cards. In the early days of credit, banks needed to figure out who would be their most active and profitable customers.

Again, demographics could only get them so far. The obvious answer was “high-income males.” But just like the eye makeup example, this group is vast and diverse. A high-income doctor, a high-income artist, and a high-income entrepreneur might have completely different spending habits. Plummer’s work in what he termed “lifestyle segmentation” aimed to find the person *within* the demographic.

The “man of action” AIO profile 🔗

The AIO study of the heavy *male* bank charge card user revealed a very specific personality. He was not just rich; he was an active, high-achieving individual. The profile described him as:

• Urbane and active: He was a “doer,” someone who was out in the city, participating in events, and not just sitting at home.
• High-achieving: He was career-focused and placed a high value on success and a-complishment.
• Concerned with personal appearance: This was a key insight. He understood the importance of image.
• An (Activity) was that he bought several new suits per year.
• Another (Activity) was that he belonged to multiple organizations or social clubs.

This profile is gold for a marketing team. The target is not just “a man with money”; he is “a man of action” who sees himself as successful and values the appearance of success. He is social, connected, and always on the move.

How this profile shapes the marketing 🔗

Without this AIO profile, a bank might send a boring letter talking about low interest rates. But with this profile, the entire strategy changes. The marketing message should not be about *saving* money; it should be about *access*, *status*, and *convenience*. The credit card is presented as a tool that enables his active, high-achieving lifestyle. It is the card that lets him buy that new suit on impulse or pay for a dinner with his club members without a second thought. The advertising imagery would reflect this: a man in a sharp suit closing a deal, dining at an exclusive restaurant, or traveling first-class. This is the power of true market segmentation: you are no longer just pushing a financial product; you are validating and empowering a consumer’s entire lifestyle.

Putting it all together: from data to campaign 🔗

AIO studies are the essential bridge between raw customer data and a creative, effective advertising campaign. They move marketers from broad assumptions to specific, actionable insights. By understanding their heavy users’ activities, interests, and opinions, companies can answer the most important questions:

• What is the right message? (e.g., “status and access” for the card user, “glamour and aspiration” for the makeup user).
• Where should we place our ads? (e.g., in business journals and club newsletters, or in high-fashion magazines).
• What tone and imagery should we use? (e.g., professional and successful, or dramatic and sophisticated).

In the end, AIO studies allow brands to stop shouting at everyone and start having a meaningful conversation with the few people who matter most.

What do you think? Can you think of a recent ad campaign that clearly targets a specific *lifestyle* or set of opinions, not just an age group? If a company were to create an AIO profile of *you* based on your recent activities and interests, what surprising things might they learn?
