Marketing & customer
AIDA
The oldest working model in marketing: move a prospect through Attention, Interest and Desire to Action. Empirically shaky as a theory of buying, yet still the most useful checklist ever written for auditing an advert, a landing page or a sales pitch.
Also known as AIDA model, AIDA funnel, Attention, Interest, Desire, Action. First set out by E. St. Elmo Lewis (attributed) in 1898; the primary source is cited in full below.
Where this is contested
Attribution is genuinely murky: the standard credit to E. St. Elmo Lewis in 1898 rests largely on E. K. Strong's 1925 account rather than surviving primary texts, the four-letter acronym only settled in early 1900s salesmanship literature, and recent scholarship has argued for Frank Dukesmith and Arthur Sheldon as originators.

Plate · The model
The components
Attention
The moment of capture: the prospect notices the message at all, amid everything else competing for the same glance. Without it nothing downstream exists, which is why headlines, thumbnails and opening seconds carry a disproportionate share of an asset's value.
Signals of strength
Stopping power in the real context, feed, search page, street, not in the review meeting · Instant clarity about who the message is for · Reach among the defined audience rather than raw impressions
Interest
The prospect stays: the message connects to their situation strongly enough that they give it further seconds. Interest is bought with relevance, specificity and the prospect's problem, told in their terms.
Signals of strength
Read time, scroll depth or listen-through beyond the opening · Content organised around the prospect's problem rather than the product's features · Engagement from the target audience, not just from colleagues and competitors
Desire
Interest becomes wanting: the prospect can picture themselves owning the result and prefers it to the alternatives. Desire is built by proof, vivid outcomes, social evidence and offer framing, and it is where trust is either established or lost.
Signals of strength
Enquiries, saved items, price-page visits and other pre-purchase behaviour · Prospects replaying the offer's language back in calls and messages · Objections shifting from 'why would I?' to 'how would it work for me?'
Action
The measurable act the whole exercise exists for: the booking, purchase, call or sign-up. The model's discipline is that action must be asked for explicitly and made frictionless; hesitation at this stage is usually a mechanics problem, not a persuasion problem.
Signals of strength
One unmistakable call to action per asset · Completion rate from intent to done, forms finished, calls answered, checkouts closed · Falling cost per completed action over time
When it earns its keep
- You are writing or reviewing a specific persuasive asset, an advert, landing page, direct mail piece or sales script, and want a structured check that it earns attention, builds a case and asks clearly for the next step.
- Conversion is poor and you need to locate the leak: plenty of traffic but no enquiries, plenty of enquiries but no bookings. The stages give you a shared language for where prospects fall away.
- You are briefing an agency or a junior marketer and need a common, instantly understood scaffold for what each piece of communication must accomplish.
- You are training salespeople in the structure of a first conversation, which is the context the model was actually born in.
And when it doesn't
- You are modelling how customers actually buy in considered or repeat-purchase categories. Real buying journeys loop, stall and restart; use customer journey mapping or the McKinsey consumer decision journey for that.
- The commercial problem is retention, loyalty or advocacy. AIDA stops at the first purchase and has nothing to say about what happens after it.
- You are planning brand-building activity over years. AIDA describes a single persuasive episode; brand effects accrue through reach and memory, which the model does not capture.
- You need to understand why customers buy. AIDA sequences attention and emotion; it says nothing about underlying needs, for which jobs-to-be-done is the better instrument.
How to run it
Before starting, gather the inputs the analysis depends on:
- A defined audience and the single next action you want from them, a call, a booking, a visit, not 'awareness'.
- Knowledge of where the audience's attention actually is: the channels, moments and formats in which they can realistically be reached.
- A genuine reason for interest and desire: evidence, offer or story that survives the question 'why would they care?'.
- Funnel data if the asset is live: impressions, engagement, enquiry and completion numbers, so stage judgements are grounded rather than aesthetic.
- 1
Define the audience and the action
Fix who you are persuading and the one action that counts as success. Every stage is then judged against that action. Assets written to 'raise awareness' in general fail the model before they start.
- 2
Audit for attention
Judge honestly whether the asset would stop the intended person in the intended context, a search results page, a social feed, a roadside. Attention is bought with relevance and distinctiveness in the first second, and most assets fail here, not later.
- 3
Audit for interest and desire
Interest is earned by speaking to the prospect's situation; desire is built by making the specific offer feel worth wanting: proof, specificity, social evidence, price framing. Mark where your asset merely describes the product, which is neither.
- 4
Audit the ask
Check there is one clear, low-friction action, and that the mechanics of taking it work. A striking campaign that resolves into 'find out more' or a phone number staffed on weekday mornings wastes everything upstream of it.
- 5
Measure each transition and fix the weakest
Instrument the stages: attention as reach and stopping power, interest as engagement, desire as enquiry or add-to-basket, action as completion. Fix the weakest transition first; effort spent polishing a stage that already converts is effort taxed at one hundred per cent.
Reading the result
A stage-by-stage audit of a persuasive asset or funnel: a judgement and a metric for each of Attention, Interest, Desire and Action, an identification of the weakest transition, and a prioritised fix.
- Read the stages as a chain that fails at its weakest link. The multiplication is brutal: excellent attention times absent desire still equals zero action.
- Diagnose by transition, not by stage. Strong traffic with weak enquiries points at interest and desire; strong enquiries with weak completions points at the ask and its mechanics.
- Remember what the model is not. It audits a persuasive episode; it does not describe real customer journeys, which loop and revisit. Hierarchy-of-effects descendants such as Lavidge and Steiner's six steps, and loop models such as the McKinsey consumer decision journey, exist precisely because buying rarely proceeds in a straight line.
A worked example
An independent driving school chain audits why enquiries are not becoming pupils
A driving school operating across three Midlands towns with 25 instructors is spending £2,400 a month on search and social advertising. Clicks are healthy but new pupil numbers are flat, and the owner suspects the money is wasted. Before cutting the budget, she audits the funnel with AIDA.
- Attention
- Working, at a price. Search ads on 'driving lessons [town]' win the click about as often as the national platforms, and a school-gate poster campaign is remembered in surveys of parents. Reach among 17 to 24 year olds is adequate; cost per click has crept up 30 per cent in a year, which raises the stakes for every later stage.
- Interest
- Leaking. The landing page leads with the school's 30-year history and a photo of the fleet. Session recordings show mobile visitors, who are 80 per cent of traffic, bouncing in under ten seconds. Nothing above the fold addresses what learners and paying parents actually weigh up: price per hour, waiting time for a first lesson, and pass rates.
- Desire
- Underpowered but fixable. The school holds genuinely strong material it does not use: a first-time pass rate above the national average, instructor continuity (the same instructor every lesson, which the app-based platforms cannot promise), and hundreds of five-star reviews trapped on a third-party site. None of this appears in ads or on the page.
- Action
- The worst leak. The only call to action is 'Call us to book', answered weekdays 9 to 5 by the office manager. Call logs show 40 per cent of calls from the ads arrive evenings and weekends, and go to voicemail. Two competitors offer instant online booking with a deposit. The advertising is buying desire and delivering it to a closed door.
The read. The audit reorders the owner's plans. Instead of cutting ad spend (attention is fine) or rebranding (interest is a page-layout problem), she rebuilds the landing page around price, availability and pass rate, surfaces the reviews and instructor-continuity promise, and adds online booking with evening confirmation. Pupil starts, not clicks, become the reported metric. The honest caveat: AIDA located the leaks in one funnel; it says nothing about the bigger strategic question of whether to defend against the app platforms on brand or on price.
Pitfalls
- Mistaking the model for a description of how people actually buy. It is a discipline for constructing messages; real journeys skip, loop and run on habit, and decades of research have failed to confirm the strict sequence.
- Measuring only the ends. Impressions and sales are visible by default; the model's value is in instrumenting the transitions between stages, which is where the diagnosis lives.
- Optimising attention in isolation. Clickbait creative that wins the glance and betrays it at the landing page raises costs and salts the audience.
- Stopping at the first purchase. AIDA has no stages for retention, repeat purchase or advocacy, which in most businesses is where the profit is; pair it with journey mapping and lifecycle work.
- Writing for the committee rather than the prospect. Assets tuned to please internal reviewers reliably over-invest in brand history and under-invest in price, proof and the ask.
What the critics say
The hierarchy-of-effects assumption underneath AIDA, that cognition leads to affect leads to behaviour in that order, has never been convincingly demonstrated. Barry and Howard's review of eight decades of research found little empirical support for a fixed sequence, while noting the family's persistence for want of an agreed replacement.

Ehrenberg's 'weak theory' of advertising inverts the model: for established, frequently bought brands, advertising mostly reinforces existing buying habits rather than converting the unpersuaded, so awareness, trial and reinforcement (ATR) describes the evidence better than a persuasion staircase.
Ehrenberg, A. S. C. (1974) 'Repetitive Advertising and the Consumer', Journal of Advertising Research, 14(2), pp. 25–34.
Funnel-shaped models fit modern purchase behaviour poorly. McKinsey's consumer decision journey research found buyers actively adding brands late in an iterative evaluation loop, with a post-purchase loyalty loop that funnels ignore, prompting much of the industry to retire the linear funnel for considered purchases.
