How new users or customers first discover your product.
In practice
Acquisition covers every channel through which someone finds you for the first time: SEO, paid ads, word of mouth, content, communities, partnerships. The classic trap: judging a channel purely on volume, without asking whether it's repeatable and whether its cost is even known (see CAC). A channel that worked once by luck isn't an acquisition strategy, it's a lucky break. And acquisition alone says nothing about product health — a spike of new visitors who never activate is just a vanity number.
The formula
New paying customers from a channel = visitors it sends × sign-up rate (visitor → sign-up) × conversion rate (sign-up → paying customer)
- Visitors it sends
Counted per channel, which means attribution: a tagged link (utm_source) on everything you publish, a "how did you hear about us?" field for the channels tags can't see. Untagged traffic is the largest channel of most early products, and it is not a channel — it is ignorance.
- Sign-up rate (visitor → sign-up)
The share of visitors who create an account, per channel — nothing more: a sign-up is not yet an active user, and not yet a customer. It measures how well the landing page keeps the promise the channel made: the same page converts differently for someone arriving from a friend's link and from a cold ad.
- Conversion rate (sign-up → paying customer)
The share of sign-ups who end up paying. "Customer" here means paying, not merely active: an active user is what activation measures; a customer is what makes a channel's cost worth it — which is why CAC below is a cost per customer, not per sign-up. This step is the part acquisition doesn't own — activation and pricing do — yet the only one that turns a channel's volume into revenue. A channel that brings thousands of sign-ups who never activate is a cost, not a source.
Multiply the three and you get the channel's yield; divide the channel's cost by that yield and you get its CAC. Acquisition is the stage where a single blended number hides the most: the whole point is to know this per channel.
Worked example
Two channels, one flattering average
- Paid social: 20,000 visitors a month, 3% sign up (600), 8% of those become customers (48). Cost: €12,000. CAC: €250.
- Founder-written articles and SEO: 4,000 visitors, 9% sign up (360), 20% become customers (72). Cost: two days of writing a month, say €2,000 of time. CAC: €28.
- Blended: 24,000 visitors, 960 sign-ups, 120 customers, €14,000 — a €117 CAC that describes neither channel.
- The channel with a sixth of the traffic brings 60% of the customers, at a ninth of the cost. Without per-channel numbers, the obvious next move — "more ads, traffic is up" — is exactly wrong.
A primary channel is not the one with the most visitors. It is the one whose economics you understand well enough to double.
Orders of magnitude
- Most successful products get the bulk of their growth from one or two channels, not ten — the observation behind the "Bullseye" method popularised by Traction (Weinberg and Mares): test many cheaply, then concentrate. A spreadsheet of nine channels each bringing 5% is a symptom, not a strategy.
- Paid channels scale fast and get more expensive as they scale; organic channels (content, SEO, community, referral) start slow and get cheaper. Early on, paid buys you learning; over time, only the compounding channels keep CAC in check.
- Landing-page sign-up rates are commonly quoted in the 2-5% range for cold paid traffic and well above that for warm traffic (a shared link, a recommendation). If a channel converts far below its peers, the problem is usually the fit between the promise made there and the page, not the page itself.
How to improve it
- Instrument attribution before anything else: tag every link you control, ask new users how they found you, and reconcile the two monthly. You cannot pick a primary channel you can't see.
- Run cheap, time-boxed tests on several channels with the same success metric — customers, not clicks — and compare them honestly. "We've tried a second one informally" is what the Tour scores at 7 because informal tests can't be compared.
- Match the landing page to the channel: the headline that works for someone arriving from a technical forum is not the one for someone arriving from a friend's shared result.
- Fix activation before scaling acquisition. Doubling traffic into a product that activates 10% of sign-ups doubles the waste; fixing activation first makes every later channel cheaper.
- Invest in one compounding channel early, even while paid does the volume: content, a community, a product-led loop. It is the only thing that makes year-three CAC lower than year-one CAC.
In the Tour
Do you have a primary acquisition channel that's identified and measured?
- Yes, clearly identified and tracked20 pts
- We have one, but don't track it closely7 pts
- Not really / it's scattered0 pts
Acquisition is the first stage of the Tour, and its three questions follow the logic above: is there a primary channel, identified and measured (20 / 7 for "we have one, but don't track it closely" / 0 for "it's scattered"); has more than one channel been tested, with real comparison; and is the CAC known. A team with real traffic but "scattered" channels usually scores in the weak band here — not for lack of growth, for lack of knowing where it comes from.
Questions people ask
What counts as an acquisition channel?
Any repeatable way people first find you that you can name, measure and invest in: search (SEO), paid ads on a given platform, content, a community, partnerships, events, cold outreach, app stores, referral from existing users. "Word of mouth" is an outcome of the others, not a channel you can buy more of — unless you build a referral mechanism, at which point it becomes one.
Should I focus on one channel or diversify?
Concentrate first, diversify later. Early on, one channel that works and that you understand beats five you half-run; spreading a small team across many channels usually means none gets the iteration it needs. Diversify once the primary channel is measured, saturating or getting expensive — and treat the second channel as a new experiment, not a copy of the first.
How is acquisition different from marketing?
Acquisition is the measured part of marketing: the specific channels that bring new users, each with a cost and a yield. Brand, positioning and messaging shape how well every channel converts, but they are not channels themselves. In the AARRR frame, acquisition ends where activation starts — the moment someone who found you actually gets value.
