Lesson 1

Growth Experiments (Applied)

Objective

Run a real growth experiment end to end.

Teach
Apply the hypothesis/time frame/metric structure from Module 21 to an actual live test, and commit to reading the result honestly — even if it disproves the hypothesis.
Real-World Example
Running the video-vs-carousel test from Module 21 for the full 14 days without changing variables midway.
Common Mistake
Ending an experiment early because early results look disappointing, before the time frame is complete.
Practical Exercise

Launch one real experiment this week with a committed end date.

Lesson 2

Hook Testing

Objective

Test multiple hooks for the same content idea.

Teach
Since the hook decides most of a post's reach (Module 7, 10), it's one of the highest-leverage things to test — same content, different opening lines or frames.
Real-World Example
Posting the same core video idea with 2 different opening hooks (on different days) to see which retains viewers longer.
Common Mistake
Testing entirely different content ideas at once instead of isolating just the hook variable.
Practical Exercise

Write 2 different hooks for the same piece of content and plan to test both.

Lesson 3

Format Testing

Objective

Test whether format (not topic) is driving performance differences.

Teach
The same topic delivered as a carousel vs. a video vs. a text post can perform very differently — isolating format reveals what your specific audience prefers.
Real-World Example
KoraSpace's own AI A/B Testing example (Section 6.6): "your audience responds 38% better to educational hooks than promotional hooks" comes from exactly this kind of test.
Common Mistake
Assuming one format "always wins" without testing it against your specific audience.
Practical Exercise

Pick one topic and plan to test it in 2 different formats.

Lesson 4

Distribution Testing

Objective

Test posting time, platform mix, or cross-promotion tactics.

Teach
Beyond content itself, distribution choices (when, where, how you promote a post) can be tested — e.g., posting time, or whether cross-promoting from Stories to feed helps.
Real-World Example
Testing two posting times for two weeks each to compare average reach.
Common Mistake
Assuming a "best posting time" from a generic blog post applies to your specific audience without testing it yourself.
Practical Exercise

Design one distribution test (timing, cross-promotion, or platform mix).

Lesson 5

Experiment Documentation

Objective

Record experiments so learning compounds instead of resetting each time.

Teach
Log every experiment's hypothesis, result and takeaway in one place — without this, teams re-run the same tests and re-learn the same lessons repeatedly.
Real-World Example
A simple experiment log table (date, hypothesis, result, takeaway) prevents "didn't we already try this?" conversations.
Common Mistake
Running experiments but never writing down what was learned, so insights are lost when the person who ran it leaves or forgets.
Practical Exercise

Create your experiment log and add your last 2 informal tests to it retroactively.
