Funnel Model
Attention, Interest, Desire, Action — the 120-year-old funnel that still organizes most marketing thinking. Where it came from, why it endured, where it falls short in 2026, and how to use it without becoming its prisoner.
AIDA describes the audience's mental progression from first encounter with a brand or product to a purchasing action. Each letter is a stage the prospect moves through.
AIDA endured because it is simple, easy to teach, and roughly true. The basic shape of buyer psychology — notice, engage, want, act — does describe the broad arc of many purchase decisions. As a teaching scaffold, it works. As a creative brief structure, it works.
It also predates measurement. Lewis wrote in an era when ad effectiveness was guessed at, not tracked. The framework didn't need to be falsifiable. It survived because it was useful regardless of what the data said.
The modern customer journey is not linear. Buyers loop back, exit, return weeks later, research on phone, decide on desktop, and convert through dark social channels you can't trace. AIDA's straight arrow underrepresents all of this.
It also has no concept of retention or referral. AIDA stops at Action. AARRR explicitly fixes this by adding Retention and Referral stages.
And it conflates awareness with attention. In a saturated media environment, attention is the scarcer resource. Many buyers are aware of your brand but never give it sustained attention. Frameworks like See-Think-Do-Care separate the audience by intent rather than by awareness, which is more actionable for media planning.
The most useful living application of AIDA today is as a creative brief checklist. For any campaign creative, ask: does this attract Attention in the first 1.5 seconds? Does it sustain Interest for the next 5–10 seconds? Does it connect to Desire (a real want, not a feature)? Does it ask for Action with a clear next step?
If any of the four stages is weak, the creative will underperform. AIDA gives you the lens to find which stage is the weak link.
