Experiment library

Growth experiments for the AI era

The old growth-hacking playbooks are full of tactics for platforms that no longer exist. These 30 experiments are built for how marketing works now, grouped by the four systems that turn attention into revenue.

Create demandGet in front of the right people before they need you.

How to use the library

Pick one experiment from the system where you lose the most money (the cost per booked job calculator will tell you which). Write down the measure and the stop condition before you start, run it for the time shown, then keep it or kill it. Costs are rough ranges for a small Australian service business.

Founder-voice clips at volume

Short clips of the owner explaining real jobs will bring enquiries more cheaply than polished brand video.

The old way
One produced brand video a quarter, edited by an agency.
The AI-era way
Film one hour with the owner. An AI editor cuts 20 clips, writes captions and five alternative hooks for each. Post daily and boost the two best each week.

$300 to $1,500 a month
Time to signal
4 to 6 weeks
Measure
Cost per enquiry from video, against your other channels
Stop if
No clip beats your median view-through rate after 20 posts

Publishing one original statistic about your trade will get you cited when people ask ChatGPT or Perplexity about it.

The old way
Blog posts written for keywords, hoping to reach page one.
The AI-era way
Run a small survey or analyse your own job data, publish the numbers on one clear page, then check every week whether ChatGPT, Perplexity and Gemini cite it.

Measure
Citations in AI answers, links earned and branded search growth

Time to signal
6 to 12 weeks
Measure
Impressions, calls and form fills per page
Stop if
Pages still not indexed after 8 weeks; merge them into fewer, stronger pages
