# Acquisition Channel Testing

Most companies get most of their growth from one or two channels, and every channel saturates eventually: costs rise, volume flattens, competitors arrive. Finding the next channel before the current one stalls is one of the most valuable things a growth team does. It works best as a structured search: list every plausible channel, score them, run cheap, fast tests with clear success criteria, and double down on the one that works.

This skill runs channel discovery and testing across paid, organic, partnerships, community, content, events, outbound, marketplaces and product-led channels, judged on the customers they bring, not just clicks or sign-ups.

## Operating principles
1. **Consider every channel before picking one.** Teams default to channels they already know.
2. **Test cheaply and quickly.** A small, time-boxed test with clear criteria beats a big launch.
3. **Judge on retained customers.** Channel quality shows in activation, retention and payback, not top-of-funnel volume.
4. **Focus wins.** Once a channel works, put most effort into scaling it before spreading wider.
5. **Expect saturation.** Watch marginal cost and volume; keep a testing pipeline running.

## Channel universe
| Category | Channels |
|---|---|
| Paid | Search, shopping, paid social, video, display, retail media, podcasts, newsletters sponsorships |
| Organic search and AI search | SEO, programmatic pages, AI answer engines |
| Content and community | Blog, YouTube, social, communities, forums, newsletters |
| Partnerships | Integrations, resellers, affiliates, co-marketing, marketplaces and app stores |
| Sales-led | Outbound email, LinkedIn outreach, events, trade shows |
| Product-led | Free tools, templates, freemium, viral and referral loops |
| PR and earned | Media, awards, original research |
| Offline | Direct mail, out-of-home, local events |

## When to use, and when not to
Use it when one channel provides most growth, when CAC is rising, when entering a new market or segment, and when planning a quarter's acquisition tests.

Don't use it to run an established channel in depth (use the Performance Marketing, SEO or Content skills) or to build loops (`growth-loops`).

## Inputs to ask for, in one message
1. Current channels with volume, cost, activation and retention by channel.
2. Target customer: who they are, where they spend time, how they buy.
3. Unit economics: maximum CAC and payback.
4. Budget and team capacity for tests.
5. Competitor channels and any past channel tests.

## Workflow

### Step 1. Brainstorm the universe
List every channel that could reach the target customer, including unusual ones.

### Step 2. Score channels
| Criterion | Question |
|---|---|
| Reach | Are enough target customers there? |
| Fit | Does the channel suit how they buy and the product's price point? |
| Cost | Is expected CAC within limits? |
| Speed to test | Can we test in weeks? |
| Scale potential | Could it become a major channel? |
| Competition | Is attention affordable? |

### Step 3. Pick three to test
Choose the top three with different risk profiles.

### Step 4. Design each test
Hypothesis, budget, duration, minimum volume, success criteria (cost per activated or paying customer), tracking and the decision rule.

### Step 5. Run and track to downstream metrics
Tag traffic properly; follow users to activation, retention and revenue.

### Step 6. Decide
Double down, iterate or stop each channel; record lessons.

### Step 7. Scale the winner
Invest until marginal CAC approaches the limit; keep a smaller testing pipeline for the next channel.

## Channel test card
```
Channel:
Hypothesis: [Customer] can be reached through [channel] at [cost] because [evidence]
Budget and duration:
Minimum sample to judge:
Success criteria: cost per activated user below X; week-4 retention at least Y
Tracking: UTMs, codes, referral fields, CRM source
Decision rule:
```

## Tracking hard-to-attribute channels
| Method | Use for | Notes |
|---|---|---|
| Unique promo or partner codes | Podcasts, influencers, partners | Codes leak to coupon sites; monitor |
| Vanity URLs | Offline, podcasts, events | Redirect with UTMs |
| "How did you hear about us?" | All channels | Self-reported; useful for direction |
| CRM source fields | Sales-led and partnerships | Require at lead creation |
| Geo or time tests | Offline, brand channels | Compare regions or periods |

## Product-channel fit
A channel works when it fits the product's price point and buying process. Low-priced self-serve products need low-cost, scalable channels (SEO, virality, app stores, paid social). High-priced products can afford sales-led channels (outbound, events, partnerships). Mismatches, such as outbound sales for a low-priced app, rarely pay back regardless of execution.

## Saturation signals
- Marginal CAC rising faster than spend.
- Volume flat despite higher budgets.
- Audience frequency rising, click-through falling.
- Competitors entering the same channel.
When two or more appear, increase the share of effort going to channel tests.

## Channel test budget guide
| Channel type | Typical minimum to judge | Duration |
|---|---|---|
| Paid social or search | Enough spend for 50 to 100 conversions on your success event | 4 to 8 weeks |
| Podcasts and newsletters | Several placements across shows | 6 to 10 weeks |
| Partnerships | Two or three active partners | 8 to 12 weeks |
| Content and SEO tools | One strong asset | 3 to 6 months |
| Communities | Consistent weekly participation | 8 to 12 weeks |
Illustrative; adjust to your conversion rates and prices.

Record every test result in the learning library, including channels that failed and why.

## Edge cases and judgement calls
| Situation | What to do |
|---|---|
| Long B2B sales cycles | Judge on leading indicators (qualified meetings, pipeline) with a later revenue check |
| Channels hard to track (podcasts, offline) | Use codes, vanity URLs, "how did you hear" surveys and geo tests |
| Small budgets | Test channels with low minimum spend or time-based effort (communities, partnerships) |
| Channel works but users don't retain | Fix targeting or message, or drop the channel |
| Team wants to test everything | Limit to three active tests at a time |

## Worked example
A B2B invoicing tool got 70% of new customers from Google Search, with rising CPCs. Scoring the channel universe put three tests on top: accountant partnerships, a free invoice template tool for search and AI answers, and LinkedIn thought leader content. Each test had eight weeks and a cost-per-activated-account target. The template tool produced the most activated accounts at the lowest cost and kept compounding; partnerships produced fewer but higher-retention accounts; LinkedIn missed the target. The company scaled the template tool, built a partner programme and dropped LinkedIn for now.

## Output format
```
# Channel testing plan: <company>, <date>
## Current channel mix and concentration risk
## Channel universe and scores
## Three tests with cards
## Tracking and attribution approach
## Results and decisions
## Scaling plan for winners
```



## Common mistakes
- Testing only familiar channels.
- Judging on clicks or sign-ups instead of retained customers.
- Tests too short or too small to judge.
- Spreading effort across too many channels at once.
- No tracking for hard-to-attribute channels.

## Questions to ask before you test
- Where do your best customers spend time and learn about tools?
- What can you afford to pay for a retained customer?
- How much budget and time can you put into tests?

## Self-check before you answer
- Did I consider the full channel universe?
- Does each test have success criteria based on retained customers?
- Is tracking set up for hard-to-measure channels?
- Is there a clear decision rule and scaling plan?
