Pricing and Promotion

The Communication Funnel: From Promotion to Purchase

A message can be clever, expensive, and memorable, and still sell nothing. This section explains why, and how to find out where it went wrong. We'll start with the communication process, and the two places it most often breaks. Then the response hierarchy, the mental stages between seeing a message and buying. We'll draw it as a funnel, and see why that picture makes failures findable. Then involvement, objective setting, and the stubborn problem of attribution. We'll finish with word of mouth, source credibility, and integrated communication. And a campaign that everyone remembered, and almost nobody acted on.

The Communication Process

8 Parts, Any of Which Can Fail

Applied to marketing, the general model of communication has eight parts. A failure at any one can derail the message. The sender originates the message. In marketing, that's a brand or a company. Encoding translates the intended meaning into symbols, words, and images. That's the creative work of an advertising team. The message is the actual content that encoding produces. The channel is the medium it travels through, like television, a social media platform, or a personal sales conversation. Decoding is how the receiver interprets those symbols, words, and images back into meaning. The receiver is the intended audience. Feedback is the receiver's response, traveling back so the sender can gauge whether the message worked. It might be measured sales, survey responses, or social media engagement. And noise is anything that distorts or interferes with the message, at any point in the chain. That ranges from competing advertisements to the receiver's own distraction. Two failure points deserve special attention. One is in encoding, and the other is noise.

Where It Breaks

The Assumption Problem, and the Wall of Noise

Start with the assumption problem in encoding. Every message is encoded using the sender's own knowledge, vocabulary, and frame of reference. A receiver who doesn't share that frame decodes the message differently, and sometimes misses the meaning entirely. Picture a technical product description, written by engineers, full of terms natural to other engineers. From the sender's view, it's perfectly clear. To a general consumer, it lands as confusing, or meaningless. This isn't a failure of effort. It's a structural risk built into encoding itself. A sender can never fully step outside its own frame, to check how differently someone else might decode the message. In marketing, noise takes one dominant form: the sheer volume of competing messages. A typical consumer meets a very large number of commercial messages in a day. And selective attention, from section twelve point five, means most are never consciously received, however well encoded. That's sobering. A perfect message that never clears selective attention has failed before decoding even begins. No care at any later stage can repair a message that was never received.

Response Hierarchy Models

Know, Feel, Do

A response hierarchy model describes the mental stages a receiver moves through, from first meeting a message to acting on it. Several models exist. They differ in their stage labels, but share a common structure of three phases. The cognitive stage concerns what the receiver comes to know. It includes awareness, simply knowing the product exists, and knowledge, understanding what it actually does and offers. The affective stage concerns what the receiver comes to feel. It includes liking, a favorable overall impression, and preference, favoring the product over specific competing alternatives. The behavioral stage concerns what the receiver actually does. It includes conviction, a settled intention to buy, and finally purchase itself, the completed action. Know, then feel, then do. That's the order the standard model assumes. We'll see shortly that some purchases don't follow it.

Table 15.3.1

Each Stage Needs Its Own Message and Measure

Each stage calls for its own objective, its own kind of message, and its own measure. Awareness aims to make people know the product exists. Simple, repeated exposure ties the name to its category. You measure it by recall, aided or unaided. Knowledge aims to convey what the product does. That takes informational content, tested by comprehension. Can respondents accurately describe what it offers? Liking aims for a favorable impression, through emotionally engaging, image-building content. You measure favorability. Preference aims to favor this product over named competitors. The message is comparative, measured by stated preference. Conviction aims for a settled intention to buy. Persuasive content tackles remaining doubts, often with offers or urgency. The measure is stated purchase intent. Purchase aims at the completed transaction, with a direct call to action. You count actual sales or conversions. Notice that the measures get harder to obtain as stages move from purely mental toward actual behavior. And here's the trap. Judge a purchase-driving message by an awareness measure, or the reverse, and you misjudge it. You'd be grading it against something it was never designed to do.

Figure 15.3.1

The Funnel Shows Where People Fall Out

The funnel framing draws the response hierarchy as a narrowing shape. A large population at the top is merely reached by a message. A much smaller number at the bottom completes a purchase. What the funnel shows, and a list of stages doesn't, is how many people fall out at each individual stage. Not just the overall gap between reached and bought. Take an illustrative campaign that runs from reach, through awareness and consideration, to purchase. The funnel narrows at every stage. But the single largest drop comes between awareness and consideration. Eighty-four percent of the people who already knew the product never moved on to seriously weighing it. So the problem isn't that people fail to notice the campaign. Awareness is reasonably strong. The problem is that the message gives aware people no reason to consider the product seriously. That points to a specific fix, at a specific stage, not a vague call to promote more. A campaign with strong awareness and no purchases has a locatable failure. The funnel lets you find it.

Involvement

When the Order Flips

The standard sequence, from awareness to purchase, assumes a level of engagement many purchases simply don't have. As section twelve point five established, a high-involvement purchase runs a fuller decision process. Communication for it can reasonably move a receiver through each cognitive and affective stage, in order, before behavior follows. A low-involvement purchase is different. The standard order is often compressed, or even reversed. Someone may try a low-cost, low-risk product with only the thinnest awareness. Liking and preference form afterward, through the experience of using it. They weren't talked into liking it beforehand. So communication for a low-involvement product often works better by prompting easy trial directly. The product itself does the work the affective stage would otherwise require. That beats trying to argue people into conviction before any purchase has happened.

Setting Objectives

Name the Stage You Are Targeting

The implication for objective setting follows directly from that table. Because the right message and measure differ by stage, a communication objective must say exactly which stage it targets. A message built for simple awareness is fundamentally different from one built to prompt an immediate purchase. It differs in tone, in content, and in length. So a campaign that tries to do both at once, in a single message, often does neither well. Building recognition and closing a sale call for different content. And frequently, they call for different channels entirely. Section fifteen point four turns this principle into a complete objective-setting framework. For now, hold onto the rule. Name the stage first, then design the message and the measure for it.

The Attribution Problem

Which Touch Made the Sale?

Measuring movement through the funnel runs into the attribution problem. That's the genuine difficulty of connecting a specific communication to a purchase that may happen weeks later. And that purchase was very likely influenced by several sources, not only the one message being evaluated. Other advertisements, word of mouth, and the customer's own prior experience all play a part. Picture a customer who sees a television ad, reads an online review, and hears a friend's recommendation. Then they visit the company's website, and buy. Who gets the credit? Dividing it accurately among those touches is genuinely difficult. It isn't just a matter of measuring more carefully. The honest statement is that attribution remains a real, persistent difficulty, not a solved problem. So any confident claim that a specific ad alone caused a specific sale deserves skepticism. Be especially skeptical when the claim comes from whoever is trying to justify that ad's budget.

Word of Mouth and Credibility

Messages You Don't Control, Sources People Trust

Word of mouth, introduced in section twelve point five, is communication a business doesn't control. It comes from customers and other independent parties, not from the business in its sender role. The digital environment has amplified it substantially. One customer's review, comment, or post can now reach an audience far larger than offline word of mouth could. And it persists. Future customers can find it long after it was written. That amplification cuts both ways. A positive account can spread well beyond the business's own promotional reach. And so can a negative one. Source credibility is the degree to which a receiver trusts and believes the party delivering a message. It acts directly on decoding. The same content is read more favorably when it comes from a trusted source. And it's more likely to move the receiver toward the later stages of the hierarchy. That's partly why word of mouth, from a friend or independent reviewer, often outweighs a business's own advertising. That holds even when the claim is identical. The receiver decodes the same words differently, depending on who says them.

Integrated Communication

Customers Hear One Business

Integrated marketing communication is the principle that customers receive all of a business's messages as one continuous impression. That covers every channel and every element of the promotional mix. And it's true whether or not the business itself coordinated them. A customer doesn't experience an ad, a sales conversation, and a social media post as unrelated messages from three departments. They experience parts of one ongoing relationship with one business. So inconsistency between them matters. A different tone, a different claim, or conflicting information. The customer reads it as evidence about the business itself, not as a mere coordination slip. Section sixteen point one develops the practical work of coordinating the promotional tools into one impression. The point here is that customers integrate your messages anyway. The only question is whether you do too.

Case Vignette

The Campaign Everyone Remembered

A final composite case. The organization and the person are fictional. Nadia is a marketing manager at Verano Home Goods. She runs a bright, memorable campaign for a new kitchen product. Post-campaign research shows awareness rose sharply, and stayed high for months. Many in the target audience can recall the campaign, and correctly describe the product. But sales stay essentially flat. Nadia could call it a failure and drop it, or rerun it with a bigger budget, hoping exposure eventually converts. Or she could investigate where in the response hierarchy the audience is getting stuck. Her constraint is a fixed remaining budget for the product line this year. The reasoning turns on locating the funnel's specific failure point, instead of judging the whole campaign at once. Strong, lasting awareness shows the cognitive stage is working. People know the product, and can describe it. Flat sales show something downstream isn't happening, most likely at liking, preference, or conviction. The campaign may be memorable, yet give no reason to prefer this product over what people already use. The sound decision is to research where the funnel narrows most sharply after awareness, and redesign the message for that stage. A campaign this memorable is a resource worth building on, once its specific failure point is found.

FAQ

Questions students ask us

About The Communication Funnel: From Promotion to Purchase

What are the elements of the communication process in marketing?
The marketing communication process has eight parts: sender, encoding, message, channel, decoding, receiver, feedback, and noise. A brand encodes its meaning into words and images, sends the message through a channel such as television or social media, and the audience decodes it, while feedback such as sales or engagement shows whether it worked. Two common failure points are encoding in the sender's own jargon and noise, chiefly the flood of competing messages.
What are the stages of the hierarchy of effects model?
The hierarchy of effects model, published by Robert Lavidge and Gary Steiner in 1961, describes six stages: awareness, knowledge, liking, preference, conviction, and purchase. These fall into three phases: cognitive, about what people know; affective, about what they feel; and behavioral, about what they do. Each stage calls for its own message and measure, such as recall for awareness and actual conversions for purchase, so judging a campaign by the wrong stage's measure misjudges it.
How do low-involvement purchases change the response hierarchy?
For low-involvement purchases, the standard know-feel-do order is often compressed or even reversed. A shopper may try a cheap, low-risk product with only slight awareness, and liking and preference then form through using it. High-involvement purchases are more likely to follow the full sequence of learning and evaluating before buying. As a result, communication for low-involvement products often works better by prompting easy trial than by building a detailed case for conviction.
What is the attribution problem in marketing?
The attribution problem is the difficulty of linking a specific marketing message to a purchase that may happen weeks later and was likely shaped by several sources. A customer might see a television ad, read an online review, hear a friend's recommendation, and then buy on the company's website. Dividing credit accurately among those touches is genuinely hard, so a confident claim that one ad alone caused a sale deserves skepticism.
