Content for a PowerPoint presentation: write the message, then the slides

Content for a PowerPoint presentation is written before the file is opened, and it is built from one controlling sentence, a sequence of arguments that support it, and one message per slide. The practical test for every slide is whether its title states a point rather than a topic. "Q3 results" is a topic. "Q3 revenue grew on new accounts, not price" is a message, and a deck of messages makes sense even when nobody is talking over it.

Write the one sentence first

Before any slide exists, finish this sentence: after this presentation, the audience should do or believe X, because Y. If you cannot finish it, the deck has no shape and no amount of design will give it one. Then write three to five supporting points, in the order that an undecided person would need to hear them. That list is your deck. Slides come last.

Four structures that hold up

Structure	Shape	Use it for
Situation, complication, question, answer	Agreed facts, then what changed, then the question that raises, then your answer	Recommendations and proposals to a senior audience
Problem, solution, proof, action	The cost of the problem, what you propose, why it works, what you need	Sales and internal business cases
Three pillars	One claim supported by three independent arguments	Teaching, conference talks, strategy updates
Before, after, bridge	Where things stand, what better looks like, how you get across	Change programmes and vision decks

Pick one and stay in it. Decks that drift between structures are the ones audiences stop following around slide nine.

Titles carry the content

Most of the content of a presentation is in the slide titles. Write them as full statements and read them in sequence: the titles alone should tell the whole story. If they do, the deck is sound. If reading them gives you a list of nouns, the thinking is not finished.

• Weak: "Market overview". Strong: "Two of our four competitors left the mid market last year".
• Weak: "Customer feedback". Strong: "Customers rate setup support above every other feature".
• Weak: "Next steps". Strong: "We need a decision on budget by the end of the month".

One idea per slide, and the split between slide and notes

Each slide holds one message, the minimum evidence for it, and nothing else. Everything you would say out loud goes in the speaker notes, where it is useful and where it does not compete with you for attention. The body of a slide is a short list of specifics, not sentences you intend to read aloud.

A workable discipline: a statement title, three to five bullets of under ten words each, or one chart with its takeaway written as the title. If a slide needs more, it is two slides or it is an appendix item.

Where the content comes from

Thin decks are usually research problems rather than writing problems. Before drafting, gather:

• The audience's own words. From sales calls, support tickets, survey comments or a short interview with two people who will be in the room.
• Numbers you can source. One number per claim, with the origin written in the notes so you can answer where it came from.
• A concrete example. One named situation beats three general statements.
• The objection. Write the strongest argument against your recommendation and answer it on a slide. Audiences trust a deck that names the risk.

Decks that get sent and decks that get presented

These need different content, and confusing them is why so many decks fail at both. A presented deck can be sparse because you are the narration. A sent deck has to stand alone, so it needs fuller titles, a short summary slide at the front, and the context you would have spoken written into the slide or into a readable appendix.

The efficient approach is one deck with two outputs: build the presented version, write complete speaker notes, and export a reading version where those notes become visible text or a short document. Never paste your notes into the slides and present that.

Charts and data slides

Every data slide needs a takeaway, written as the title, and a chart that shows only what supports it. Strip gridlines, extra series and decorative axes. Label the one point you are talking about directly on the chart. If a chart needs a paragraph of explanation, the wrong chart was chosen, and a table or two simpler charts will say it faster.

Make the content reusable and readable

• Use the outline view and real text placeholders rather than text boxes, so the content is editable, searchable and exportable.
• Write alt text for images and charts. It serves screen readers, and it is also the only description of that image that any software can read.
• Keep one slide master and a short set of layouts, so content moves between decks without reformatting.
• Name the file and the slide titles in plain language, because a PDF of this deck may be the version people find later.
• Turn the strongest three slides into a one page summary, a short post and an email. The content was the expensive part; the format is cheap.

content for a PowerPoint presentation: what is still unclear

How much text should be on a slide?

A statement title plus three to five short bullets, or one chart with its conclusion as the title. Anything you intend to say word for word belongs in the speaker notes.

How many slides for a thirty minute talk?

Count arguments, not minutes. Three to five supporting points, two or three slides each, plus an opening and a close is a comfortable thirty minutes. Keep the detail in an appendix for the questions.

Can AI write my presentation content?

It is useful for turning material you already have into a first draft: a transcript into an outline, a report into slide titles, a long slide into a shorter one. Decide the controlling sentence and the evidence yourself, because that is where the thinking lives, then draft and tighten with whatever tool you like.

What goes in speaker notes?

The narration, the source of each number, the answer to the obvious objection, and the transition to the next slide. Write them in full sentences so somebody else could deliver the deck.

How do I open a presentation?

With the thing the audience cares about, not with your agenda. A specific situation, a number that surprises, or the question you are there to answer. Agenda slides are a courtesy, so keep them to one line.

Should I write the content in PowerPoint or elsewhere?

Write the controlling sentence, the supporting points and the slide titles in a document first. It takes minutes and stops you spending an hour formatting a slide you later delete.

The version of your pitch that writes itself

The same content you put into a deck is now summarised for buyers before they ever see your slides. Ask ChatGPT, Gemini or Perplexity what a company does and who it suits, and you get a short written answer assembled from pages, documents and sources those systems read, including PDFs of decks published on websites. That answer reaches people who will never open your presentation.
