No coding.

Units and bites

  1. Unit 16 bitesAbout 18 min

    Metrics that matter

    Which numbers help you decide, and which only look nice.

    1. Decision metrics vs vanity metrics

      A good metric changes what you do next.

      3 min
    2. Reach, clicks, conversions

      The three layers of campaign numbers and what each one tells you.

      3 min
    3. Conversion rate

      Calculating it, comparing it, and not being fooled by a changing denominator.

      3 min
    4. Customer acquisition cost (CAC)

      What it costs to win one new customer, channel by channel.

      3 min
    5. Customer lifetime value (LTV)

      What a customer is worth over time, and why it has to beat CAC.

      3 min
    6. ROAS vs ROI

      Revenue per rupiah of ads is not the same as profit.

      3 min
  2. Unit 25 bitesAbout 15 min

    Funnels

    Seeing the customer journey as a chain of rates, and finding the weakest link.

    1. The funnel as a chain of rates

      From visit to cart to payment: every step has its own rate.

      3 min
    2. Where people drop off

      Finding the step that loses the most people.

      3 min
    3. Funnels by channel

      Why traffic from ads, search and email behaves differently.

      3 min
    4. Micro-conversions

      Small steps — saving a product, joining a newsletter — that predict a purchase.

      3 min
    5. Fix the narrowest step

      Working out where a small improvement pays off most.

      3 min
  3. Unit 36 bitesAbout 18 min

    A/B tests

    Comparing two versions fairly, and reading the result without fooling yourself.

    1. What an A/B test answers

      One change, two random groups, one question.

      3 min
    2. One metric, chosen up front

      Why picking the metric after seeing results is a sure way to find a fake winner.

      3 min
    3. How many people you need

      Small differences need big samples — an intuition for sample size.

      3 min
    4. Reading the result

      The difference, the uncertainty, and what "significant" means in plain words.

      3 min
    5. Don't peek

      Stopping a test when it looks good makes the result untrustworthy.

      3 min
    6. When not to test

      Low traffic, obvious changes, or decisions that are easy to reverse.

      3 min
  4. Unit 45 bitesAbout 15 min

    Attribution

    Which channel deserves credit for a sale — and why no answer is perfect.

    1. Who gets the credit

      A customer sees an ad, reads a review, then searches on Google. Who made the sale?

      3 min
    2. Last click

      The most common attribution model, and the channels it always favours.

      3 min
    3. Multi-touch

      Splitting credit across touches, with assumptions you should know.

      3 min
    4. Incrementality

      The more honest question: how many sales wouldn't have happened without this campaign?

      3 min
    5. Living with uncertainty

      Making budget decisions when attribution is never certain.

      3 min
  5. Unit 55 bitesAbout 15 min

    Cohorts and retention

    Do customers come back? Following groups of customers over time.

    1. What a cohort is

      Grouping customers by when they started.

      3 min
    2. Retention curves

      Reading the chart that shows how many customers stay.

      3 min
    3. Churn

      The rate customers leave, and why a small monthly churn adds up over a year.

      3 min
    4. LTV from cohorts

      Estimating customer value from real cohort data, not assumptions.

      3 min
    5. Repeat purchase

      A simple metric that often matters more than winning new customers.

      3 min
  6. Unit 65 bitesAbout 15 min

    Segmentation and dashboards

    Grouping customers usefully, and reporting numbers people actually read.

    1. RFM segmentation

      Recency, frequency, monetary: a customer segmentation you can build in a spreadsheet.

      3 min
    2. Segments that behave differently

      A good segment calls for a different action; otherwise it's just a label.

      3 min
    3. A dashboard people use

      Few numbers, one question per chart, and a clear comparison.

      3 min
    4. Weekly reporting

      A reporting rhythm that catches problems early without causing panic.

      3 min
    5. Telling the story

      From numbers to a recommendation: what happened, why, and what we do now.

      3 min
