Traction (channels)

On this pageWhat I like
What I like about this book
It does one thing very well: it stops you guessing where your next customers will come from. The nineteen channels give you a full menu, and the Bullseye process gives you a cheap way to pick from it. I also like that it admits most channels will fail for you, and treats that as the point of testing.
Why read it
It gives you a repeatable way to find the one channel that brings customers, instead of trying every tactic at once.
Most teams that can build a product have no plan for finding customers, and the book is aimed at exactly that gap. It is organised around one decision: which acquisition channel gets your attention next.
The problem it solves
A common pattern is a good product, a launch, and then silence. The authors argue that failed companies nearly always have a product and lack customers. Their fix is a process for choosing a channel, with a method for testing it before you commit.
What changes in how you work
After reading, you stop asking "what marketing should we do?" and start asking "which three channels could plausibly work, and what is the cheapest test of each?". You write down guesses for cost per customer and volume, run small tests, and replace the guesses with numbers.
You also start to judge ideas by one question from the book: could this move the needle for us right now? A mention on a small blog matters at ten customers and is noise at ten thousand. That filter alone removes a lot of busy work.
Why the breadth matters
Each of the nineteen chapters covers a channel in enough detail to run a first test: how the channel works, who has used it, and what to try. The authors say founders ignore channels out of habit, dislike or an aversion to tedious work. As they put it, "What Lean is to product development, Bullseye is to traction." Reading the chapters you would normally skip is the cheapest way to find an advantage your competitors do not have.
When to read it, and when not to
Read it when you have something people want and growth has stalled, or before you launch, since the book wants traction work to run beside product work. It is less useful if you have no product yet and no idea who it is for, because the tests need a real offer to test.
The examples are from 2013 and earlier, so treat the specific tools and prices as dated. The method and the channel list still hold up as a checklist.
How it connects to a decision log
The Bullseye spreadsheet is a decision record in miniature: each idea, your estimate, the test you ran and the result. If you keep it, the next time growth flattens you can see which channels you tested, what they cost and why you chose one. That also makes channel work easier to turn into a playbook that someone else, or an agent, can run: the set-up, the tracking and the weekly test are all repeatable steps.

Key take-aways
Book summary
Traction by Gabriel Weinberg and Justin Mares argues that a startup's best chance of surviving is traction, a measurable sign that customers want what you sell. After interviewing more than forty founders, the authors found nineteen channels that startups have used to get it, and they give a process for choosing among them.
Prologue: Traction Trumps Everything
The opening sets out the claim that carries the whole book. Traction means customers buying or a user base growing, and it makes fundraising, hiring, press and partnerships easier. The authors introduce themselves: Weinberg founded DuckDuckGo and Mares ran growth at a cloud company later acquired by Rackspace. As they write, "traction trumps everything".
Traction Channels
Chapter 1 defines traction as quantitative evidence of demand and as growth itself. It then lists the nineteen channels, each tied to the founders interviewed for it. Two findings frame the rest: founders default to the few channels they already know, and nobody can predict which channel will work best until they test. The chapter ends by asking which channels you are biased for or against.
The Bullseye Framework
Bullseye is the book's core method. You brainstorm at least one idea for every channel, rank the channels into an inner circle, a potential ring and a long-shot ring, and then prioritise three inner-circle channels. You test those cheaply, in parallel, and focus on the one that works. If none does, you repeat the process with what the tests taught you.
The tests should answer three questions: what a customer costs, how many are available, and whether they are the customers you want. The authors cite Mint, which tested blogs, PR and search ads, focused on blogs for its first 40,000 customers, and then repeated the process and moved to PR.
Traction Thinking
This chapter gives the strategy that sits across all channels. The 50% rule says to spend half your time on product and half on traction, in parallel. The authors call the opposite habit the Product Trap, the belief that better product alone will bring customers. They compare Bullseye to Lean Startup: Lean finds the right features, Bullseye finds the right channel.
Three further ideas follow. Moving the needle means only pursuing activity large enough to matter at your current size. Growth comes in phases: making something people want, marketing it, then scaling, and the channel that works changes between them. The leaky bucket image says not to pour money into traction until the product keeps the customers it gets.
The chapter also covers investors and pivots. Sustained growth is hard for investors to ignore even when the numbers are small. Before pivoting, look for bright spots, small groups of users who are truly engaged, and ask why they love it.
Traction Testing
Testing is how you find a channel and then improve it. The authors cite Andrew Chen on how every channel saturates over time, so you keep running small experiments to stay ahead. Early tests should be cheap, such as a few hundred dollars of search ads, and must have tracking in place first. Once a channel works, A/B tests optimise it, and the authors say a test a week can improve results two to three times.
They also ask you to quantify. Put cost to acquire a customer and lifetime value in a spreadsheet for every channel, and do the sums on whether a channel could ever deliver enough customers.
Critical Path
Critical Path decides what to work on. Pick a traction goal that would change something significant for the company, list the milestones that are absolutely necessary to reach it, order them, and do the first ones and nothing else. Anything off the path is not done. After each milestone you reassess, since the original plan is often wrong.
DuckDuckGo is the example: product features customers kept requesting were left out until the next goal made them necessary. The chapter extends the idea to departments and individuals, recommends mentors, and names three reasons founders skip channels: they are out of sight, disliked, or tedious.
Viral Marketing
This channel depends on users bringing in other users. The authors describe types of loop, from word of mouth to incentives and embedded widgets, and give the viral coefficient: invites per user multiplied by the share who convert. Above 1 you get exponential growth, and above 0.5 helps considerably. Viral cycle time, how fast a user completes the loop, also matters. Loops usually need building into the product.
Public Relations (PR) and Unconventional PR
Traditional PR means press coverage. Stories tend to filter up from small blogs to larger outlets, so the advice is to build real relationships with the right reporters and pitch only when you have a newsworthy milestone. Unconventional PR covers publicity stunts and going far beyond what customers expect, which is less crowded and more sustainable when done as customer appreciation.
Search Engine Marketing (SEM) and Social & Display Ads
Paid search captures people already looking for something, so it works at any phase. Do not expect early tests to be profitable. Aim for near break-even after a few weeks, test keywords, copy and landing pages, and watch quality scores. Social and display ads work differently: they generate demand rather than harvesting it, and an indirect approach of building an audience first usually converts better.
Offline Ads
Offline spend still exceeds online, and few startups use it. Tests are cheap, a local radio spot or a billboard for a few hundred dollars. Check the demographics of each medium, buy remnant inventory for discounts, and use unique codes or web addresses to track each campaign.
"Search Engine Optimization (SEO)" and Content Marketing
SEO comes down to content and links, with a choice between a fat-head strategy of short, competitive terms and a long-tail strategy of many specific ones. Avoid black-hat tactics such as buying links. Content marketing means a blog that is a real acquisition source, and the authors suggest committing at least six months, writing about customers' problems, and using your own data for posts nobody else can write.
Email Marketing and Engineering as Marketing
Email is personal, so the more it reflects what a customer did, the better it performs. Build a list whatever you focus on, and use automated lifecycle sequences. Engineering as marketing means building free, single-purpose tools such as HubSpot's Marketing Grader, which keep bringing in leads after a small upfront cost.
Targeting Blogs and Business Development (BD)
Targeting blogs your customers read is one of the best ways to win a first wave of customers, though it is hard to scale. Business development is partnership: both sides gain, and the book stresses understanding the partner's incentives and keeping a steady pipeline because most deals fail.
Sales and Affiliate Programs
Sales suits higher-priced products that need hand-holding. The goal is a repeatable model with a funnel that qualifies leads, and the first customers are those with a burning need who will work closely with you. Affiliate programs pay people or companies for sales or leads, so they depend on how much a customer is worth to you. Start with an existing affiliate network and with your own users.
Existing Platforms, Trade Shows and Offline Events
Existing platforms are app stores, browser extension stores and social networks, where you aim for rankings or features and for untapped corners with less competition. Trade shows reward preparation: visit first, book meetings in advance and tie the booth to a goal. Offline events cover attending, sponsoring or running conferences and meetups, which suit customers who do not gather online.
Speaking Engagements and Community Building
Speaking starts with small free talks, and organisers weigh timing, topic and credibility. Most good talks tell a story. Community building rests on evangelists, users who spread the word, and on setting quality standards early so the community can police itself.
Afterword
The authors close by saying the book took more than four years and over forty interviews, and that it gives you an actionable plan: nineteen channels, Bullseye to choose, and Critical Path to stay on course.
What to do with it
- List one concrete idea for each of the nineteen channels in a spreadsheet, including the ones you dislike.
- Add columns for the chance it works, the expected cost per customer and the volume available, then rank the channels into three rings.
- Pick three inner-circle channels and run one cheap test for each, with tracking set up before you start.
- Choose a traction goal, write the necessary milestones in order and drop work that is not on that path.
- When growth flattens, repeat the exercise rather than pushing harder on the saturated channel.
