The 17 Rules That Make People Buy From You
Funnels, ads, social media. None of it works without understanding these rules first.
The other day I was talking with someone who was overwhelmed.
They’d tried funnels, paid ads, lead magnets, and four different social channels. Nothing was working.
They asked me:
“Why does this work for everyone else and not for me?”
The answer isn’t the tools.
Selling and marketing haven’t changed. The tools have. The platforms have. But the people receiving your messages haven’t changed at all.
We are still wired for survival. We avoid loss. We seek gain. We follow the crowd. We trust the familiar. We buy from people we like.
That’s human biology.
No algorithm changes that. No platform rewires thousands of years of human nature.
These are the rules that transcend tools and tactics.
They work in person, on a call, in an email, in a post, in a DM. Master them and the medium stops mattering.
But one thing before you read on.
Every rule here requires you to know exactly who you are talking to.
Not broadly - specifically.
One person, one problem, one situation.
Without that, these rules have nothing to work with.
Get clear on that first. Then use what follows.
1. Humans are distracted.
Most people are not sitting waiting for your message.
They are busy, stressed, and surrounded by noise. Every day the average person is exposed to thousands of messages, adverts, emails, and posts.
The brain filters most of them out without the person realising it. If the first thing they read doesn’t feel immediately relevant to them, they move on.
Lead with the problem your audience already has, not your name or your company
Read your opening line and ask: would someone who doesn’t know me stop for this
Remove anything in the first sentence that isn’t directly about the reader
2. Humans are self-interested.
This isn’t a criticism of people. It’s how the brain works. The brain is wired to prioritise information that affects the person reading it. Everything else gets filtered out.
When someone reads your post, email, or message, they are not thinking about you. They are asking one question without realising it: does this matter to me.
If the answer isn’t obvious, they stop reading.
Start every piece of communication with the reader’s problem, not your background or story
Go through your content and replace every “I” and “we” with “you” wherever it makes sense
Before you post or send anything, ask: if I were the reader, would I care about this
3. Humans avoid loss more than they seek gain.
Two psychologists, Daniel Kahneman and Amos Tversky, spent years studying how people make decisions. They found that losing something feels roughly twice as painful as gaining something feels good.
The fear of a problem getting worse, or the cost of doing nothing, is a stronger motivator than the promise of something new and better.
Most marketing focuses on the gain. The more effective approach is to help people feel the weight of the problem they already have.
Describe what happens if your audience does nothing and stays where they are
Show the real cost of the problem they are living with, in time, money, or stress
Don’t just talk about what they’ll get. Talk about what they’re losing by waiting.
4. Humans are suspicious of being sold to.
People have been marketed to their entire lives. They have developed a finely tuned radar for when someone is trying to push them toward a decision.
The moment someone feels like they’re being pitched at, their guard goes up. They start looking for the catch. The harder you push, the more they resist.
This is why aggressive sales tactics and heavy promotional language produce the opposite of the intended effect.
Give genuine value before you make any offer, whether that’s useful content, honest advice, or real insight
Let people reach their own conclusion rather than telling them what to decide
Remove any language from your communication that sounds like an advert or a rehearsed script
5. Humans buy with emotion (then logic)
A neuroscientist, Antonio Damasio, studied patients who had damage to the part of the brain that processes emotion. These patients were intelligent and could process information well. But they were unable to make decisions.
They would analyse options endlessly and never choose. What Damasio found was that emotion is not a distraction from decision making. It is a requirement for it.
People feel their way to a decision first, then use facts and logic to confirm it was the right call.
Open with how your client will feel after working with you, not a list of what’s included
Use real stories to create an emotional response before you present any facts or figures
Don’t lead with features. Lead with the feeling, then back it up with proof.
6. Humans need to feel understood before they’ll listen.
The brain is constantly running a background check on every situation it encounters, asking: is this relevant to me, does this person get my situation, is it worth reading on.
If a message doesn’t reflect someone’s reality, the brain files it as irrelevant and moves on.
When someone reads something and thinks “that is my situation,” their defences drop. They give you their attention. They keep reading.
Understanding your audience in detail is not optional. It is the foundation of everything.
Use the exact words and phrases your audience uses to describe their own problem, not the words you use to describe it
Talk to your existing clients about how they felt before they worked with you and use that language in your content
Write as if you are speaking to one specific person, not a broad general audience
7. Humans trust the familiar.
A psychologist called Robert Zajonc identified something called the mere exposure effect. He found that people develop a preference for things because they have seen them before, even if they don’t remember seeing them.
Familiarity feels safe. The unfamiliar feels risky. This is why being seen consistently over time is not vanity. It is a commercial strategy.
Show up consistently so people see you and your message on a regular basis
Keep your message, tone, and visual identity consistent so people recognise you
Don’t disappear for weeks at a time and expect people to remember who you are
8. Humans follow the crowd.
When people are uncertain about what to do, they look at what other people are doing and use that as a guide.
Psychologist Robert Cialdini called this social proof. The thinking is simple: if other people like me have already done this, it’s safe for me to do it too.
Reviews, testimonials, case studies, and numbers are not nice to have. They are proof that removes the fear of being first.
Share client results, testimonials, and case studies as a regular part of your content, not just on a website page nobody visits
Be specific about who you’ve helped, naming the types of people, industries, and outcomes they got
Show volume where you have it. Numbers like “500 clients” or “11 countries” signal that you are an established, trusted choice.
9. Humans buy from people they like.
Social psychologist Robert Cialdini found that liking is one of the most consistent drivers of whether people say yes.
Given two similar products at a similar price, people choose the one sold by someone they like more. This doesn’t mean being entertaining or having a big personality. It means being real, being consistent, and being someone your audience can relate to.
People like people who are honest, who share a point of view, and who feel like a real person rather than a corporate voice.
Share your opinions and perspectives, not just information and tips. People like people who stand for something.
Be consistent in your tone and style so people feel like they know you over time
Stop trying to appeal to everyone. The more specific you are about who you help and what you believe, the more strongly certain people will connect with you.
10. Humans buy from people they trust.
Trust is the single biggest factor in whether someone buys from you. Research from Harvard Business School shows that trust outweighs price, product quality, and convenience in purchase decisions.
Trust is not built in one conversation or one piece of content. It is built through repeated exposure to someone who knows what they’re talking about, does what they say, and has the results to prove it.
You cannot shortcut trust. You can only build it over time.
Share your knowledge freely and consistently without attaching an offer to every piece of content
Be transparent about what you do, who you help, and what you don’t do
Document and share real client results so people can see evidence of what you produce
11. Humans act when the timing is right for them.
Most people who come across your content are not ready to buy right now. Research shows that in most markets, only around 3 to 5 percent of your audience is ready to buy at any given time.
The rest are at different stages. Some are aware they have a problem but haven’t decided to fix it. Some are comparing options. Some will be ready in six months.
The majority of people you reach today are not lost leads. They are future buyers who need to keep seeing you until the timing is right for them.
Build a way to stay in regular contact with people over time, not just when you have something to sell
Create content that speaks to people at different stages, not only those ready to buy right now
Don’t write someone off because they didn’t respond. Follow up over months, not days.
12. Humans need repetition before they believe something.
Seeing or hearing something once is rarely enough to change how someone thinks or behaves. The brain builds credibility through repeated exposure to the same message over time.
Studies in advertising have found that people need to encounter a message multiple times before it feels credible enough to act on.
Saying the right thing once is far less effective than saying it repeatedly.
Repeat your core message consistently across every channel and format you use
Don’t assume people saw something the first time you shared it. Say it again in a different way.
Build a content system that keeps your message in front of people regularly, not just when you feel like posting
13. Humans make decisions based on identity.
People don’t just buy products or services. They buy things that fit with how they see themselves or how they want to be seen.
Psychologist Henri Tajfel spent decades studying how identity shapes human behaviour. He found that people’s sense of who they are influences almost every decision they make, including what they buy and who they buy from.
If your offer feels out of place with how someone sees themselves, they won’t buy it even if they need it. If it fits their identity, the decision feels natural.
Speak to who your buyer wants to become, not just what they want to have
Use language that reflects the values, beliefs, and self-image of the people you are trying to reach
Show people who look like your ideal client already getting results, so the decision feels like a natural fit
14. Humans are paralysed by too many choices.
Psychologist Barry Schwartz studied what happens when people are given too many options. He found that more choice does not help people decide. It makes decisions harder and more stressful.
When people feel overwhelmed by options or confused by a complicated process, they do the easiest thing available: nothing. This is called decision fatigue.
Every extra option, condition, or step you add to your sales process increases the chance that someone walks away without deciding.
Give one clear offer with one clear next step, not a menu of options for people to work out themselves
Remove complexity, conditions, and jargon from your sales process so the path forward is obvious
If you have multiple products or services, guide people to the right one rather than listing everything and leaving them to choose
15. Humans value what they pay for.
Researcher Dan Ariely ran experiments showing that price shapes how much people value something. When something is free, people engage with it less and get less from it.
When something costs money, people pay more attention, put in more effort, and place more value on what they receive.
Price is not just a number. It is a signal. It tells people how seriously to take what you’re offering.
Charge appropriately for what you deliver and don’t apologise for your price
If you offer free content or resources, make them substantial and well produced, not an afterthought
Understand that lowering your price to win clients reduces how much they value what you do
16. Humans are influenced by authority.
Psychologist Robert Cialdini identified authority as one of the core principles of human influence. People defer to those they perceive as experts.
When someone appears knowledgeable, experienced, and credible, others are more likely to trust their advice and follow their recommendations.
Authority is not about titles alone. It is about demonstrating that you know what you’re talking about through the quality of your thinking and the results you’ve produced.
Share the clients you’ve worked with and the results you’ve produced clearly and regularly
Write and speak with confidence. Over-qualifying and excessive caveats undermine how authoritative you appear.
Don’t hide your track record out of modesty. Stating facts about your experience is evidence, not arrogance.
17. Humans remember stories, not facts.
Neuroscientist Uri Hasson at Princeton University found that when someone tells a story, the brain of the listener starts to mirror the brain of the storyteller. Stories create a shared experience in a way that facts and data cannot.
A list of features tells people what something is. A story about a real person solving a real problem makes them feel what it’s like. Facts inform the brain. Stories move it.
Use real client stories to illustrate every point you make rather than stating a claim and expecting people to believe it
Structure your stories simply: here is the situation, here is the problem, here is what changed, here is the result
Make the client the hero of the story. Your job is to be the guide who helped them get there, not the star of the show.
These rules don’t expire.
They worked before the internet existed.
They worked before social media.
They’ll work after whatever comes next.
The tools will keep changing. Human beings won’t.
