New vs. already engaged users: why one ad cannot work equally well for everyone
You have an ad that works great for retargeting. You decide to run it to a cold audience. The result? Nothing.
Or vice versa: creative that works great with cold traffic but seems weak and bland to people who already know your brand.
Most marketing advisors will tell you, "You need to segment your audiences." That's correct, but it doesn't explain why.It's not just about different interests or demographics. It's about the fact that the brain functions differently depending on the context of familiarity.
When someone sees your brand for the first time, their brain is in evaluation and caution mode. When they already know you, it's in recognition and confirmation mode.
The same ad can't serve both modes at the same time.
Cognitive fluency: why the familiar feels right
In 2008, psychologist Adam Alter conducted an experiment: he showed people two stocks and asked them which one sounded like a better investment. The only difference? The name of the company—one had an easy-to-pronounce name, the other a complex one.
The result: people consistently chose the company with the easier name. Not because they knew anything about it, but because ease of processing was interpreted as reliability.
This is cognitive fluency — the psychological phenomenon whereby things that are easy to process are perceived as true, reliable, and desirable.
But here's the key point: familiar things are, by definition, easier to process. Therefore:
- A brand you've seen five times sounds more reliable than a brand you're seeing for the first time.
- A message that repeats something you've already heard feels "right."
- A product whose name you've seen before seems to be of higher quality.
This means that when you advertise to people who already know you, you are working with cognitive fluency. When you advertise to strangers, you are working against it.
And that's why you can't use the same message.
What cold audiences want (and why it's not what you think)
The typical mistake: marketers think that cold audiences need more promises.
"They don't know us, so we have to tell them how amazing we are!"
The result: ads full of superlatives, promises of transformation, and claims that sound too good to be true.
The problem? The cold brain isn't looking for promises. It's looking for a framework.
Framework means:
- Context"Who is this for?" (not "How great is this?")
- Category"What can I compare this to?" (not "Why is this unique?")
- Relevance:Does this have anything to do with me?" (not "Should I believe this?")
Examples:
❌ Cold audience, bad approach:
"Our revolutionary platform will transform your business and increase sales by 300%!"
✅ Cold audience, good approach:
"If you send more than 100 emails a week to customers, you're probably losing orders because of slow responses. Here's how we solved it."
The first ad asks for trust without having built it. The second creates a framework — "Oh, they're talking about my problem. Let me see."
Why retargeting language breaks conversion with cold people
Retargeting ads rely on one assumption: you already know about us.
That's why they start with things like:
- "Come back and finish your order."
- "Ready to get started?"
- "Don't miss out on this offer."
- "Still thinking?"
All of these phrases assume context. They don't explain what you do because they don't need to — the person has already been to your site.
But what if this ad appears to a cold audience?
The brain says, "What order? What offer? What are we thinking about?"
And if it can't build context in 2 seconds, it scrolls on.
The most common mistake in campaigns:
They create one "universal" ad and run it everywhere. The result:
- Cold people find it pretentious or confusing.
- Warm people find it generic and impersonal.
They lose both audiences.
The contrast in the message: cold vs. warm
Let's see what the message for the same product (e.g., SaaS for sales automation) would look like at different stages:
Cold audience (never heard of you):
Focus: Problem + category
Language: Concrete, descriptive, zero assumptions
Example: "If your team processes quotes manually, errors and delays are inevitable. See how companies like yours automate this process."
Why it works: It creates a framework. People say, "Yes, that's my problem," and are ready to learn more.
Warm audience (visited the site, saw content):
Focus: Differentiation + proof
Language: Slightly more direct, mentions specifics
Example: "Unlike other CRM systems, we integrate with your email in 2 minutes — no IT support required."
Why it works: They already know what you do. Now they want to know why you, not the others.
Hot audience (left an email, started a trial, abandoned a cart):
Focus: Specific action + removing doubt
Language: Direct, personalised, understanding
Example: We know that integrations can sound complicated. That's why our team will set everything up for you — free of charge."
Why it works: They don't have to convince you of the value — it's already clear. They remove the last friction point.
Note: none of these messages work well at the wrong stage.
What happens in the brain at different stages
Cold audience (doesn't know you):
The brain is in skepticism and filtering mode.
- Automatically looks for reasons not to pay attention
- Doesn't recognise the brand → lack of cognitive familiarity → feels uncertain
- Looks for quick signals: "Is this for me? Is this serious?"
What kills conversion:
- Overly bold promises (sound implausible)
- Jargon and internal terms (create confusion)
- Assumption of knowledge ("as you know," "our new version")
Warm audience (has seen you several times):
The brain is in evaluation and comparison mode..
- It has a basic framework of who you are
- It is now actively deciding whether to act
- It is looking for specific answers: "Why you? What's different?"
What kills conversion:
- Overly general messages (don't answer their questions)
- Repeating initial promises (already heard them)
- Lack of social proof or specifics
Hot audience (engaged, almost ready):
The brain is in final verification and justification mode.
- Already wants to buy, but is looking for confirmation
- Sensitive to minor friction points: price, process, risk
- Seeking "permission to buy": guarantee, ease, approval
What kills conversion:
- Overly aggressive tactics (unnecessary pressure)
- Lack of confidence in the process (unclear next step)
- Ignoring emotional support ("Am I doing the right thing?")
Common mistakes between funnel stages
Mistake 1: Using a warm message for cold traffic
You've seen it: an ad that says, "Are you ready to join 10,000+ customers?"
To someone who doesn't know you: "Who are you and why should I care?"
Mistake 2: Using a cold message for hot traffic
The opposite: someone has visited your site 5 times, left an email, watched a demo... and you show them an ad saying "Get to know our platform."
Result: "I already know you. Why are you wasting my time?"
Mistake 3: Skipping the warm stage
Going straight from cold to "Buy now." This only works if:
- The product is extremely simple (familiar)
- The price is very low (low risk)
- You have huge brand recognition
For everything else: you need an intermediate stage of building trust.
Mistake 4: Treating retargeting audiences as a monolith
Not all "retargeted" audiences are the same:
- Saw an ad ≠ Visited the site ≠ Started registration ≠ Abandoned order
Each of these stages has a different level of awareness and different objections.
Practical principle: tailor your message to the state of mind
Instead of thinking "what ad should I make," ask yourself:
"What does this person's mind know at the moment they see the ad?"
If the answer is "nothing" → create a framework, don't make promises.
If the answer is "basic things" → differentiate yourself, don't explain from scratch.
If the answer is "almost everything" → remove the last doubt, don't persuade.
An ad is good or bad depending on who sees it.
The problem is not the ad's design. The problem is that you treat different states of the brain as if they were the same.
And while targeting determines who you reach, the message determines whether you reach the right part of the brain.
If you want your advertising to work for the right audience, at the right time, and with maximum effectiveness, contact a specialist who understands why some ads work for some people and others don't, and knows how to tailor messages and strategies specifically for you.
