1.4 · Smoke Test: Run It and Read the Signal
Module 1 · Lesson 1.4 · [CORE] · From Idea to First Paying Customer
Input: a live landing page with Clarity + GA4 installed (from Lesson 1.3)
Output: a go / iterate / kill decision on your hypothesis, backed by real demand signal
Progress: M1 · 4 of 5 · Results so far: hypothesis sentence + live landing page + Clarity + GA4 installed
You have a live page and tracking installed. Now you need cold strangers to see it - people with no reason to be polite to you, which rules out friends and your LinkedIn network. A stranger who hands over an email address is voting with something real; a friend saying “sounds great” is voting with kindness.
After this lesson you will be able to: make a go / iterate / kill decision on your hypothesis based on what 300 cold strangers do with your page.
Pick your ad channel based on who your hypothesis names in the [customer] blank. The dollar ranges below are CPC (cost-per-click - what one ad click costs you):
- Selling to individual people → Meta Ads ($0.70-$1.90 CPC). Best when the product is visual and the audience is broad.
- Selling to businesses, by job title → Google Search ($3-$8 CPC) if your customer Googles the problem; LinkedIn ($5.50-$22 CPC) if they don’t.
- Developer tools → Reddit Ads ($1.25-$3 CPC) in r/programming, r/webdev, r/SaaS.
- Niche vertical → Google Search long-tail ($1-$5 CPC) - real estate, dentists, contractors Googling pain.
Budget: your channel’s CPC × 300 visits, plus ~20% slack for ad iterations. On Meta that’s $210-$570 in clicks - plan $250-$700 total; on LinkedIn, $1,650-$6,600 before slack. Not ready to spend? Start with the $0 organic path on the full channel guide - slower but real.
Start ad-account setup 2-3 days before launch. First-time ad accounts can take 24-72 hours to approve. Meta is the slowest; Reddit clears same-day.
Launch:
- Install your channel’s pixel. Open your ad platform’s pixel manager: Meta → Events Manager, LinkedIn → Campaign Manager, Reddit → Ads Manager. Copy the pixel snippet, paste in your page builder’s head-tag field - same process as Clarity and GA4 in Lesson 1.3. Open your page in an incognito window; verify the pixel fires in your platform’s dashboard. Google Ads users: skip this (GA4 is your pixel).
- Verify your ad account is approved and payment method attached. If not, set it up tonight.
- Create and launch your campaign. Open the campaign creation recipe for your channel (Meta, Google, LinkedIn, or Reddit). Each recipe walks you through 7 settings: objective, budget, audience, placement, creative, tracking, and launch. Set a daily budget that gets you to 300 visits within 5-7 days.
- Do not touch the page. Resist headline rewrites, bid adjustments, and hourly dashboard refreshes for the full run. You want raw demand against the original hypothesis - not an optimized funnel.
- After 300 visits, read your conversion rate (form submits ÷ page views) against this table:
| Conversion rate from cold traffic | Decision | What to do |
|---|---|---|
| Under 3% | Kill or pivot | Hypothesis is wrong. Rewrite the weakest blank and re-test. |
| 3-6% | Iterate the message | Rewrite headline or try a different audience. Same hypothesis, different framing. |
| 6-10% | Promising | Move to Module 2 interviews. Talk to the people who signed up. |
| 10-20% | Strong signal | Run interviews + Product Brief in parallel. |
| Over 20% | Suspicious | Either hot market OR broken targeting. Verify with a second channel. |
On a boundary (exactly 6%, 10%, or 20%)? Take the higher band’s action.
✅ Success check: you have a conversion rate from ≥300 cold visits AND a go/iterate/kill decision written down.
If this fails: conversion is below 3%. Why: your [customer] or [differentiation] blank is too vague - strangers don’t recognize themselves in the headline. Fix: go back to Lesson 1.1 and tighten the blank that scored lowest on your 4-lens test.
If this fails: conversion is above 20%. Why: either you have a hot market (rare) or your ad targeting is too narrow (common). Fix: run a second channel briefly. LinkedIn 22% + Reddit 3% = your LinkedIn targeting is the variable, not the hypothesis. Both channels near the rate = the signal is real.
When you read the results, notice which number surprised you most - surprise means the data disagreed with something you believed, and whichever hypothesis blank produced that belief is the one worth testing first in Module 2.
Done: ≥300 cold visitors have seen your page and you have a conversion rate read against the go/iterate/kill table. Decision written down.
You have now: Founding Hypothesis (1.1) + clear landing page (1.2) + tracking (1.3) + cold-traffic data + a go / iterate / kill decision (1.4). Price test is next.
Next: 1.5 · Price Your Hypothesis on the Smoke-Test Page - adds a Stripe button so you can find out if strangers will pay, not just sign up.
If blocked: see “If this fails” above. If the ad budget is out of reach, use the $0 organic path on the full channel guide - slower but real.
