Session 5: Organic & Paid Promotion

Ellis Dennis Graham 105-minute class 15 min read · 2,106 words

Organic reach and paid advertising are different tools with different jobs, and using the wrong one for the wrong purpose is how budgets disappear. This session covers how organic distribution works, what paid advertising actually buys you, and how targeting and objectives determine whether money produces customers.

Learning objectives

By the end of this session you will be able to do each of these without prompting.

  • Explain how organic reach is distributed and what increases it
  • Distinguish what organic and paid promotion are each good for
  • Understand the auction model that determines what an advert costs
  • Choose an ad objective matched to what you actually want
  • Build audience targeting specific enough to be useful
  • Plan a small paid test that produces information rather than losses

The taught content

How organic reach actually works

Organic reach is not a lottery — it is a response to signals. A platform shows your content to a small sample first, watches how they behave, and expands distribution if the signals are good. The signals that matter are watch time and completion (did they finish it?), saves and shares (was it worth keeping or passing on?), comments (did it start a conversation?) and profile visits and follows (did it make someone want more?). Likes are the weakest signal of all, which is why a post can get many likes and reach nobody.

This explains several things that otherwise look arbitrary. The first line matters because it decides whether the sample keeps reading. Short, well-paced video performs because completion rate is easy to achieve. Useful content gets saved, which is a strong signal. And posting when your audience is online matters because early engagement determines whether distribution expands at all.

Organic is slow, free and compounding. It builds an audience that chose you, and that audience is genuinely valuable — but it takes months, and reach is never guaranteed because the platform can change how it distributes tomorrow. That is the honest position: organic is an asset you are building on someone else's land.

What paid advertising actually buys

Paid promotion buys speed and precision. Where organic waits for an algorithm to decide, paid puts your content in front of chosen people immediately — a specific age range, location, interest or behaviour — and tells you exactly what it cost. It also lets you retest: the same message to two audiences, two messages to the same audience, and know within days which combination works.

The auction is the mechanism. You are not buying a fixed slot; you are bidding against other advertisers for attention from the same people, and what you pay depends on how many advertisers want that audience and how well your advert performs. This produces the counter-intuitive result that a better advert can cost less per result than a worse one, because the platform rewards content people engage with. Poor creative is not just ineffective — it is expensive.

The honest limits: paid advertising amplifies whatever you give it. A clear message to the right audience produces customers at a predictable cost. A confused message to a broad audience burns money quickly and teaches you almost nothing. And paid cannot fix a business problem — if your prices are wrong, your product is poor or your WhatsApp replies in two days, advertising will simply make more people discover that.

Choosing an objective

Every campaign starts with an objective, and the objective determines who the platform shows your advert to — not merely how it is measured. Choose awareness and it seeks people who watch and remember; choose traffic and it seeks clickers; choose messages and it seeks people who start conversations; choose conversions and it seeks people with a history of buying.

This is why an objective chosen carelessly produces a strange result: an awareness campaign measured in reach looks successful while producing no sales, because it was never aimed at buyers. Match the objective to what you actually need next. New and unknown? Awareness or reach, cheaply, to build recognition. Have attention but no enquiries? Messages or lead generation. Have enquiries but need volume? Sales, aimed at people who have already engaged.

The common beginner error is running a sales objective with no history and no tracking. The platform has nothing to learn from and no way to know who bought, so it optimises blindly and the cost per result is high. Early campaigns usually perform better with a messages or traffic objective while you gather data, then move to sales once there is a pattern to learn from.

Audience targeting

Targeting has three layers. Demographics — age, gender, location — which for a Nigerian business usually means being specific about location: Lagos is not one market, and Ikoyi and Ikorodu are not the same customer. Interests — what people follow and engage with — which is useful but broad, since an interest in fashion covers millions. Behaviours and connections — people who engaged with your account, visited your site, or look like your existing customers.

The last layer is the most powerful and the least used. Retargeting shows your advert to people who already engaged with you — watched a video, visited a page, messaged you — and they convert far more cheaply than strangers, because they already know who you are. A small business spending its whole budget on cold strangers is paying the highest possible price for attention.

Size matters and it is a trade-off. A very narrow audience gets a precise message but can become expensive and exhausted; a very broad one is cheap to reach but the message has to be generic, so it converts poorly. For most small Nigerian businesses the productive range is a city or two, a defined age band, and two or three genuine interests, then letting the platform's own optimisation do the fine work rather than stacking twenty narrow conditions.

Planning a small paid test

The way to spend money well is to spend a little first, on purpose. A test needs one question — will this message to this audience produce enquiries at a cost I can afford? — and enough budget to answer it. A campaign with ₦2,000 total tells you nothing; the platform never exits its learning phase. Set a daily budget you can sustain for at least a week and judge the result at the end of the week, not on day one.

Test one variable at a time. Two messages to one audience, or one message to two audiences — not both, or you will not know what caused the difference. Give each variant enough impressions to be meaningful; a difference based on fifty impressions is noise, not information.

Then decide against a number you set before you start. If your product's margin can support ₦800 per enquiry, and the test produces enquiries at ₦2,400, the answer is not to spend more — it is that the message, the audience or the offer needs changing. Writing down the target cost per result beforehand is what stops a disappointing campaign from being talked into a second chance.

Instructor demonstration

The instructor compares organic and paid for one business, then builds a complete paid campaign on paper: objective chosen from the business's actual need, three-layer targeting, a small test budget with a target cost per result, and the decision rule that will be applied at the end of the week.

  1. 01

    Show organic distribution

    Take a real post and explain how early signals determined its reach. Show that likes are the weakest signal while saves, shares and completion are strong.

  2. 02

    Diagnose a post that failed

    Examine a post with likes and no reach and identify the weak first line. Explain that the sample decided early and distribution never expanded.

  3. 03

    Contrast organic and paid

    Lay out speed, precision, cost and control side by side. Explain that organic builds an asset slowly while paid buys immediate, measurable attention.

  4. 04

    Explain the auction

    Show how competition for an audience and advert quality both set the price. Explain why a better advert can cost less per result than a worse one.

  5. 05

    Name the honest limits

    State that paid amplifies whatever you give it. Show that slow WhatsApp replies or wrong prices defeat any budget.

  6. 06

    Choose the objective

    Ask what the business needs next and select the objective from that. Explain that the objective determines who sees the advert, not just how it is measured.

  7. 07

    Show a mismatched objective

    Display an awareness campaign praised for reach while producing no sales. Explain it was never aimed at buyers.

  8. 08

    Build demographic targeting

    Set a city and an age band, and explain that Lagos is not one market — Ikoyi and Ikorodu are different customers.

  9. 09

    Add interests and behaviours

    Choose two or three genuine interests, then show the engaged-audience option and explain why it is the most powerful and least used.

  10. 10

    Set up retargeting

    Build an audience of people who engaged with the account. Explain that they convert far more cheaply than strangers because they already know you.

  11. 11

    Set the test budget and question

    Write the single question the test answers, set a daily budget sustainable for a week, and explain why ₦2,000 total tells you nothing.

  12. 12

    Write the decision rule

    Calculate the affordable cost per enquiry from the product margin and record it before launch. Explain that this is what stops a weak campaign getting a second chance.

Guided practice

Plan an organic push and a paid test

You design both sides of promotion for one real business: an organic plan built on the signals that actually drive distribution, and a complete paid campaign on paper — objective, three-layer targeting including retargeting, a test budget, and a written decision rule with a target cost per result.

  1. 01List the signals that drive organic distribution and rank them by strength.
  2. 02Review your last ten posts and identify which signal each one optimised for.
  3. 03Rewrite the weakest post's first line to hold attention in the first moment.
  4. 04Choose the one organic signal you will deliberately optimise for over the next month.
  5. 05State what the business needs next: recognition, enquiries or volume.
  6. 06Choose the campaign objective from that need and write one sentence justifying it.
  7. 07Set demographic targeting: specific cities, an age band, and any other relevant filter.
  8. 08Choose two or three genuine interests rather than a long narrow stack.
  9. 09Build a retargeting audience of people who already engaged with the account.
  10. 10Write the single question the paid test is designed to answer.
  11. 11Set a daily budget you can sustain for at least seven days.
  12. 12Calculate the affordable cost per result from the product's margin and write it down.
  13. 13Decide the one variable the test will change, leaving everything else fixed.
  14. 14Write the decision rule: what result means scale, change or stop.

The standard we hold you to

An organic plan naming the signals that drive distribution with the weakest post's hook rewritten, plus a written paid campaign: objective chosen from a stated business need and justified, three-layer targeting with specific cities and a retargeting audience, one test question, a daily budget sustainable for seven days, a target cost per result calculated from margin before launch, one variable changed, and a decision rule stating what result means scale, change or stop.

Common mistakes and how to fix them

You judge posts by likes

Fix: Likes are the weakest distribution signal. Watch completion, saves, shares and comments — a post with many likes and no reach means the sample decided early and distribution never expanded.

You expect paid advertising to fix a business problem

Fix: Paid amplifies whatever you give it. If prices are wrong, the product is poor or messages go unanswered for two days, advertising makes more people discover that rather than making more people buy.

You chose the objective by habit rather than need

Fix: The objective determines who the platform shows your advert to. An awareness campaign optimised for reach will not produce sales, however good the numbers look.

You ran a sales objective with no history

Fix: Without engagement history and conversion data the platform optimises blindly. Start with messages or traffic while you gather data, then move to sales once there is a pattern to learn from.

You spent the whole budget on cold strangers

Fix: Build a retargeting audience of people who already engaged with you. They convert far more cheaply, and ignoring them means paying the highest possible price for attention.

You stacked twenty narrow targeting conditions

Fix: Use a city or two, an age band and two or three genuine interests, then let the platform optimise. Over-narrowing makes the audience small, expensive and quickly exhausted.

You tested with too little budget

Fix: A campaign with ₦2,000 total never exits the learning phase and tells you nothing. Set a daily budget you can sustain for a week and judge the result at the end of it.

You set no target cost per result

Fix: Calculate the affordable cost per enquiry from your margin and write it down before launch. Without it, a disappointing campaign always finds a reason to continue.

Expert notes

The habits that separate someone who can do this from someone who does it well.

  • Optimise for saves, shares and completion rather than likes. Those signals are what expand distribution, and content built to earn them reaches further than content built to be admired.
  • Retarget people who already engaged before spending on strangers. It is the most under-used option available to a small business and it converts at a fraction of the cold-audience cost.
  • Match the objective to what you need next, not to what sounds ambitious. Awareness when unknown, messages when you have attention but no enquiries, sales when you have a pattern worth scaling.
  • Write your target cost per result before you launch, calculated from your margin. Deciding the pass mark in advance is the only reliable protection against talking a weak campaign into a second week.

Homework before the next session

Rank your last ten posts by signal

For each, note completion, saves, shares and comments rather than likes. Find the pattern in what expanded and what did not, and rewrite the weakest hook.

Choose and justify an objective

State what the business needs next — recognition, enquiries or volume — and select the objective that serves it, with one written sentence of justification.

Build a retargeting audience

Create an audience of people who engaged with the account or visited the site. This is the cheapest attention available to you and most small businesses never set it up.

Write the decision rule

Calculate the cost per enquiry your margin can support, set a seven-day daily budget, and write what result means scale, change or stop. Do it before launching.

Session questions

How much do I need to start with paid advertising?+

Enough to run for at least a week at a daily budget the platform can work with. A tiny total never exits the learning phase and tells you nothing. Start with the smallest amount that gives seven days of data, judge it against a target you set beforehand, and scale only what proved itself.

Should I boost posts or use the ads manager?+

Boosting is simpler and reaches people who already follow you and their connections; the ads manager gives real targeting, retargeting and objectives. Use boosting to amplify a post that already performed well organically, and the ads manager for anything you are actually measuring.

Why did my advert cost more than my friend's?+

Cost is set by competition for the same audience and by how well your advert performs. A narrower or more contested audience costs more, and weak creative costs more too, because the platform rewards content people engage with. Compare audiences and creative, not budgets.

Is organic dead? Do I have to pay now?+

Organic reach has fallen, but it is not dead — short video and genuinely useful content still reach far beyond followers. The honest position is that organic is slow and paid is fast, and most businesses need both: organic to build an audience, paid to accelerate what already works.

How do I know when to stop a campaign?+

Against the number you wrote before launching. If your margin supports ₦800 per enquiry and the campaign produces them at ₦2,400 after a full week, stop and change the message, audience or offer. Deciding in advance is what prevents a weak campaign from being argued into another week.
