Why Doesn’t Advertising Always Work the Way We Imagine?

Many companies share the same story: they invest hundreds to thousands of euros in advertising, look at the results a few weeks later, and conclude: “Advertising doesn’t work.” They often infer that the problem lies with Facebook, Google, or the agency itself—when the real cause runs much deeper: the strategy, the message itself, and how the advertising is connected to the website and business goals.

Research by Rex Briggs and Greg Stuart, summarized in the book What Sticks – Why Advertising Fails and How to Guarantee Yours Succeeds, found that roughly 37% of ad spend is simply wasted. The main reasons are misunderstood customer motivations, weak messaging, and a poorly chosen media mix. That means nearly a third of the money goes into ads that have no chance of working, no matter how well they’re set up technically.

At the same time, we live in an era when people actively avoid ads. According to a Nielsen survey, as many as 64% of consumers on free video platforms deliberately take steps to skip or avoid ads, and 59% are willing to pay for services where they won’t see ads at all. Advertising therefore doesn’t have the luxury of time—it has to be very good, very quickly understood, and relevant, otherwise people will simply ignore it.

In the following sections, we’ll look at why advertising often doesn’t work, what good advertising looks like through the lens of data, what it needs to include, and what must come before it to have a real chance of delivering results—whether you’re a small local business or a larger brand with a budget in the thousands of euros.

Why a large share of ads fail

Advertising rarely fails because “the algorithm is bad” or “people don’t respond to ads anymore.” Data shows the problem is usually in the campaign’s foundations—what the ad says, who it says it to, and how it fits into the overall marketing mix. When Briggs and Stuart analyzed dozens of campaigns by major brands, they found that a significant portion of waste comes from companies not understanding the real reasons people buy from them—and the advertising reflecting none of it.

Another big problem is advertising being completely disconnected from the customer’s reality. The company focuses on “our product,” “our market,” “our promotion,” but customers only care whether it helps solve their specific problem—whether they’ll feel less tired, save time, earn more, or feel better. If an ad communicates primarily about the company rather than the customer’s life, in practice it stops working in the very first second.

The situation is further complicated by the ad avoidance mentioned above. Nielsen shows that most people today actively avoid ads, and at the same time they’re strongly affected by inflation and reduced purchasing power. That means advertising has to not only capture attention but also persuade someone who’s more cautious and feels they can’t afford to waste money on non-essentials.

Many campaigns also fail because they’re planned “from the desk”—without anyone talking to real customers, looking at their language, their objections, and the reasons they buy—or don’t buy. When insight is missing, advertising is built on assumptions and chance, not reality.

The most common mistakes in ads: from weak insight to a bad media plan

1. The ad has no clear objective
Many campaigns include a line in the brief like “the goal is to increase sales.” That’s more of a wish than a goal. Advertising might aim, for example, to increase brand awareness, capture leads, persuade existing customers to buy again, or launch sales of a new service. If everything is mixed into one—“a bit of brand, a bit of sales, a bit of everything”—the result is diluted and produces no clear effect.

2. Misunderstanding the customer and their motivations
Briggs and Stuart show that one of the main reasons ad budgets are wasted is misunderstanding what truly motivates customers to buy. A company may assume people buy based on price, while in reality trust, a guarantee, delivery speed, or a sense of safety may matter more. If the ad is built on the wrong motivation, it can be technically “nice,” but it simply misses the core of the decision-making process.

3. Weak or average creative
An analysis of multiple studies cited by Advertising Week found that the quality of the creative itself accounts for roughly two-thirds of the sales effect of digital ads—Nielsen even reports that strong creative can be responsible for up to 86% of sales lift in digital campaigns. This means that even with perfectly set targeting and budget, an average ad is still only average. If the first seconds of a video don’t hook anyone, if a banner blends into its surroundings, or if the text is too complicated, people will simply move on.

4. Incorrect targeting and frequency
Targeting is often too broad (“everyone 18 to 65”) or, conversely, extremely narrow. Targeting that’s too broad can burn through the budget without a clear effect; targeting that’s too narrow leads to a Slovak user seeing the same ad 20 times and becoming genuinely annoyed by it. Without sensible frequency settings, evaluation, and optimization, even a formally “well-targeted” campaign is doomed to underperform.

5. Poor connection between the ad and the website or sales process
An ad can be excellent, but if after the click someone lands on a slow website, a confusing landing page, or a page that doesn’t contain what the ad promised, results will be poor. From the moment someone sees the ad to the purchase itself, all steps must hold together—copy, visuals, the offer, the form, the price, and the ordering process.

What good advertising looks like: what the data shows

One of the most cited analyses of advertising effectiveness, the report The Long and the Short of It by Les Binet and Peter Field for the IPA, examined a thousand campaigns over more than 30 years and showed that the most profitable advertising combines long-term brand building with short-term sales activation. Long-term campaigns focused on emotion, story, and brand deliver double the profit compared to purely short-term promotional campaigns, but the best results come from brands that combine these two approaches.

Good advertising therefore has two layers. In the short term, it must drive a specific action—purchase, click, inquiry, booking. In the long term, however, it must also help people remember the brand at all, feel positively about it, and be able to distinguish it from competitors. IPA data shows that emotionally driven advertising is about twice as effective as purely rational advertising and also delivers double the profit.

The data also suggests that even the best creative doesn’t work if it doesn’t reach enough people and runs for too short a time. A strong ad shown to a small group for a few days will remain statistically insignificant, even if it’s creatively outstanding. That’s why, in planning, it’s important not to look only at “cost per click,” but at whether the ad is also building the brand—through repetition, consistent elements, and a longer presence in the market.

What a good ad must include (a practical checklist)

Below is a practical checklist of elements an ad should include if it’s to have a real chance of working. This isn’t dogma, but if one point is missing entirely, it’s a red flag.

1. A clear, specific campaign objective
   The ad should have one primary objective: for example, generate 200 inquiries per month, sell 50 units of a new product, increase store visits by 20%, or build awareness within a new target group. The objective should be measurable and time-bound so that, at the end, you can objectively say whether the advertising worked or not.
2. A precisely defined target audience and insight
   It’s not enough to know you’re targeting “women aged 25–45.” You need to understand what problem they have, what they fear, what motivates them, and what language they use. An insight might sound like: “Young parents worry they’ll spend money on a course their child won’t enjoy anyway.” The ad can then respond directly to that fear, rather than generically promising “the best course on the market.”
3. One main idea (not ten benefits at once)
   A good ad communicates one main benefit. That could be speed, saving money, quality, simpler administration, convenience, or peace of mind. If an ad tries to explain five different advantages and three technical parameters in a few seconds, people won’t remember anything.
4. A strong opening (headline or the first seconds of a video)
   In the online world, you often have less than two seconds to capture someone’s attention. Instead of generic phrases like “A revolutionary new product,” the headline or the first seconds should immediately show the problem and the solution: “Tired of waiting a week for your order? We deliver within 24 hours.” A strong opening increases the chance someone will at least watch or read through.
5. Distinct visual identity and memorable brand assets
   Colors, logo, signature graphic elements, or a mascot—all of these help people connect the ad with the brand. Data from the IPA suggests that campaigns targeting a broader market and using consistent brand assets (colors, logo, slogan) achieve significantly more major business effects. (thinkbox.tv) If the ad looks completely different every month, with no shared elements, building the brand becomes much harder.
6. Proof that what you promise is true
   Reviews, ratings, specific numbers, case studies, or examples of results. People are naturally skeptical, so it’s important to show it’s not just an empty promise. In a small campaign with a budget of a few hundred euros, a simple proof point (for example, a screenshot of ratings from Heureka or a concrete savings figure) can be what decides whether someone clicks or not.
7. A clear call to action (CTA)
   “Order now,” “Book an appointment,” “Get a free quote,” “Download the ebook”—people must know exactly what to do. If the CTA is missing, or buried in the text, the ad may build awareness but won’t generate tangible results.
8. Adaptation to the specific channel
   An ad for a billboard, radio, YouTube, TikTok, a podcast, a newsletter, or search cannot look the same. Good advertising takes into account where and in what situation someone will see it—whether they’re in a car, on a tram holding a phone, or at home watching TV. Simple tweaks to copy and format can make the difference between an average campaign and a much better one.
9. A well-thought-out offer and a realistic price
   If a product costs €2,000, the ad must create a completely different level of trust and explanation than for an impulse purchase of €20. The higher the price, the more people weigh the risk and need reassurance that they’re not buying a “pig in a poke.” More expensive products therefore often require more steps—education, case studies, comparisons, and sometimes even personal consultations.
10. A measurement and optimization plan
    From the moment you launch, you should know how you’ll adjust campaigns based on data. How much does one relevant reach, click, inquiry, or sale cost; what is still an acceptable price and what isn’t; and what you’ll do if results don’t move in the right direction. Without this plan, a campaign can easily turn into “burned” budget that simply gets switched off after a month.

What needs to happen before good advertising

Good advertising doesn’t start in a design tool or an ad account. It starts earlier—when a company honestly answers the question, “Who is our customer, and what problem are we truly solving for them?”

The first step should be a customer and market analysis. This can include interviews with real customers, review analysis, observing which questions repeat in emails or phone calls, and also looking at which keywords people search for in connection with the given problem. The goal is to formulate specific insights, not generic phrases.

Next comes defining goals and KPIs. You’ll need a different type of campaign if you need to quickly sell old inventory than if you want to build a brand in a new market over the course of a year. Long-term brand goals and short-term sales goals should complement each other, not compete—something IPA data also confirms, showing that combining brand building and activation delivers the highest long-term profit.

A very important document is the creative brief. It shouldn’t be just a formality, but a practical translation of strategy into language a copywriter, designer, and media buyer all understand. It should include:

• a clear campaign objective,
• a description of the target group and the insight,
• the main benefit and proof,
• tone of voice,
• mandatory assets (logo, slogan, color palette),
• information on where the ad will be displayed.

Finally, you also need a testing plan. Larger brands often test different creative versions, objectives, or offers before a full rollout to minimize risk. A smaller company can also start with a small budget sample—e.g., test two versions of a headline or image—and only then decide, based on results, where to invest hundreds or thousands of euros.

How to tell whether your advertising is really working

Measuring advertising success is its own discipline, but the basic principles are similar across channels. In performance campaigns (PPC, social media, newsletters), it’s mainly about knowing:

• how much one relevant click costs,
• how much one inquiry or order costs,
• your average profit per customer,
• and whether ad costs are paying back with a margin.

For brand campaigns, different indicators matter—for example, an increase in searches for the brand name, growth in direct website traffic, ad recall, or message association with the brand. Nielsen has long shown that metrics like “ad recall” and “message association” closely correlate with later sales—but only when the creative itself is high quality.

It’s important to view the numbers in the context of time. Short-term metrics (clicks, immediate conversions) are excellent for quick optimization, but according to the IPA they can also be a poor indicator of long-term effectiveness when used in isolation. If a company looks only at cost per click and ignores brand building, it may save budget in the short term, but undermine its profit potential in the long run.

Video: why advertising often fails (in English)

If you understand English and want a more practical, direct-response perspective on the topic, it’s worth watching an interview with Dan Kennedy on why most ads don’t work and what to do about it. The video gets straight to the point and shows how to think about advertising in terms of results, not creative awards.

Summary: advertising isn’t a lottery—it’s a process

Advertising doesn’t work like those “legendary campaigns” not because small businesses don’t stand a chance, but because key steps are often skipped—understanding the customer, clear objectives, strong creative, and disciplined measurement. Research data shows that a large share of ad budgets is spent on messages nobody cares about, or on campaigns that run for too short a time in the wrong media.

Good advertising doesn’t start in design or in an ad account—it starts with strategy. It needs insight, a clear objective, a strong idea, proof, and a call to action; it must be adapted to the channel and supported by a sensible budget. When all of this is in place and results are continuously evaluated, advertising stops being a “money pit” and becomes an investment with a real chance to drive growth—whether you’re a small local business or a large brand.
