You will be able to recognise the AIDA and PAS formulas and pick the structure that fits how aware your reader already is.
Most copywriting formulas describe the same shape from slightly different angles, so once you can see that shape you can use whichever formula fits your reader. AIDA and PAS are the two you are most likely to meet, and both line up closely with the problem, solution, proof, action structure from lesson 4.1.
Writing about copywriting uses many acronyms: AIDA, PAS, BAB, FAB, 4Ps and others. Some writers treat these formulas as trade secrets and others dismiss them as gimmicks, and both views miss the point. Each formula describes how a reader moves from their situation to doing something, and the different acronyms put the weight in different places.
AIDA stands for attention, interest, desire, action. It describes the steps a reader goes through on the way to responding to an ad: something catches their attention, they get interested enough to read on, they come to want what is offered, and then they act. It is usually credited to E. St. Elmo Lewis, an American advertising writer, around the end of the 1890s, and it has been used to describe advertising for more than a century. If you took the Digital marketing foundations course, you met it in lesson 2.2, "Why the funnel is a useful lie", as an early version of the funnel.
AIDA describes how the reader's mind moves more than it gives you a template for the page. You can still map it onto page parts. Attention is the headline or hook. Interest is the opening that makes them read on, often the problem described in the reader's words. Desire is where your benefits and proof do their work. Action is the call to action.
In lesson 4.1, Priya wrote an outline for a free trial page for small-group maths tutoring (an invented example), with a class of six meeting on Saturdays. Rewritten as AIDA, the attention step is the headline "Knows it at home. Goes blank in the test." The interest step explains that many children who understand the topic still lose marks when they rush or panic, and parents only find out when results come in. The desire step says that in a class of six the tutor checks every child's working, so mistakes get caught on Saturday morning, and a parent testimonial says her son stopped making the same careless mistakes. The action step asks the reader to book a free Saturday trial.
PAS stands for problem, agitate, solution. You name the problem, make the reader feel its cost more sharply, and then present the solution. It works best for readers who already feel the problem and need a push to act.
The agitate step is what sets PAS apart. To agitate is to stay with the problem and spell out what it costs the reader, for longer than AIDA would. Priya's outline as PAS has three parts. Problem: the child knows the work but goes blank in the test. Agitate: marks lost to careless mistakes add up across a paper, and every result brings the same argument at home. Solution: a class of six where the tutor catches those mistakes every Saturday, followed by the free trial. An agitation line in this style might mention the same careless mistakes every test, the same dinner-table conversation with every result slip, and the next exam getting closer.
Agitation is where copy most often goes wrong, because it is easy to slide from describing a real cost into inventing fear. Telling a worried parent that their child's future is ruined if they fail PSLE maths is a false, frightening claim, and it doesn't count as agitation. Money and health copy is especially prone to this kind of fear: one hospital bill wiping out a family without the right insurance, or a common food silently damaging your heart. Fear-based copy overrides the reader's judgement, damages trust and can mislead. In regulated sectors it can also break specific rules, as lesson 3.3 explained.
To check your own agitation, go through each cost you describe and ask whether it is real, typical and in proportion. Then ask whether the reader would agree, on a calm day, that it is fair. If either answer is no, take that cost out. Honest agitation reminds the reader of a cost they already feel, while dishonest agitation manufactures one.
You now have three structures: problem, solution, proof, action; attention, interest, desire, action; and problem, agitate, solution. All three start with the reader and their situation, and all three end with something the reader can do. They differ in where they put the emphasis. AIDA's opening has to earn attention before anything else. PAS spends longer on the problem, which suits readers who already feel it. Problem, solution, proof, action makes proof its own step, which suits sceptical readers and any case where trust is the main barrier.
To choose, judge how aware your reader is, using the idea of reader awareness from lesson 2.1.
A reader who barely knows they have a problem needs AIDA's attention and interest steps to bring them in. A reader who already feels the problem may respond to PAS, as long as the agitation is honest. A reader who is comparing options and doubting claims needs a standalone proof step.
You can also mix them where it helps. Most good pages open like AIDA, describe the problem a little longer like PAS, and give proof its own place like the four-part structure.
In the activity you will rewrite your lesson 4.1 outline twice. Keep the facts the same and change only the shape, so the difference you notice comes from the structure and not from new material.
Rewrite your outline from lesson 4.1 twice, once as AIDA and once as PAS, and write down which version suits your reader best.
