Applies the Bullseye Framework from Traction by Gabriel Weinberg and Justin Mares. Use when choosing growth channels, testing customer acquisition strategies, or deciding where to spend marketing effort. Covers all 19 traction channels with selection methodology, testing protocol, and phase-matched

Note: This skill is independent analysis and commentary, not a reproduction of the original text. It synthesizes the book's core ideas with modern startup practice, surfaces where frameworks are outdated or incomplete, and integrates perspectives from adjacent disciplines. For the full argument and context, read the original book. Traction "Almost every failed startup has a product. What failed startups don't have is enough customers." Gabriel Weinberg Should You Use This Skill? The Core Insight Poor distribution not product is the number one cause of startup failure. Most founders are product people who neglect traction. They assume that if they build something great, customers will come. They won't. The 50% Rule "Spend 50% of your time on product and 50% on traction." This is not "build first, then market." It is: pursue product development and traction in parallel from day one. Traction work informs product decisions. Product decisions constrain traction options. Marketo built SEO and a blog before the product existed. By launch, they had a 14,000 buyer pipeline waiting. Why Founders Get This Wrong The 19 Traction Channels Every startup's growth comes from one or more of these channels. Most founders only consider 3 4 of them. The rest are invisible and that's where the opportunity is. Channel Best For 1 Viral Marketing Products with inherent sharing loops 2 Public Relations Launches, story driven products 3 Unconventional PR Stunts, customer appreciation, standing out 4 Search Engine Marketing (SEM) Existing demand, measurable ROI 5 Social & Display Ads Demand generation, audience targeting 6 Offline Ads Mass market, local businesses, older demographics 7 Search Engine Optimization (SEO) Long tail demand, content rich products 8 Content Marketing Thought leadership, inbound leads 9 Email Marketing Activation, retention, upsell 10 Engineering as Marketing Free tools that attract your audience 11 Targeting Blogs Phase I startups, niche audiences 12 Business Development Partnerships, distribution deals 13 Sales High value, enterprise products 14 Affiliate Programs High CAC verticals (finance, hosting, dating) 15 Existing Platforms App stores, social platforms, marketplaces 16 Trade Shows B2B, compressed relationship building 17 Offline Events Community driven products, long sales cycles 18 Speaking Engagements B2B, thought leadership, enterprise 19 Community Building Developer tools, marketplaces, passion products "Founders tend to use traction channels they're already familiar with. This is a mistake. The channel that will work for your startup is probably one you haven't considered." The Bullseye Framework Five steps to find the ONE channel that moves the needle right now. Step 1: Brainstorm Generate at least one concrete idea for every one of the 19 channels. Not "we could try SEO" but "we could write comparison pages for every competitor and rank for '[competitor] alternative'." Audit your biases: Which channels are you ignoring because they seem "unsexy"? Which channels would your competitors never try? Which channels feel like too much work? (That's where the opportunity is.) Step 2: Rank Sort all 19 into three columns: Column A: Inner Circle Column B: Potential Column C: Long shot Most promising 3 channels Could work, less confident Unlikely, but possible Test these first Test if A fails Revisit later Step 3: Prioritize Narrow Column A to exactly 3 channels. Not 5. Not 1. Three. For each, answer four questions: 1. Cost to acquire a customer through this channel? 2. How many customers are available through this channel? 3. Are the customers the RIGHT customers (quality)? 4. What's the time to acquire (cycle time)? Step 4: Test Run cheap, parallel tests on all three inner circle channels. Testing rules: Spend ~$250 per channel to get a signal (not $25,000) Run 2 4 ads, not 40 Test whether the channel CAN work, not whether it's optimized Time box: 1 2 weeks per test Measure: cost per acquisition, volume, quality, cycle time "The goal of testing is not to get traction. It is to determine whether a channel could work." Step 5: Focus At any given time, one channel dominates your customer acquisition. Once you find it through testing, pour all traction effort into it. Optimize aggressively. Wring it dry. When the channel saturates (rising costs, diminishing returns), re run the Bullseye Framework from Step 1. Three Product Phases Different things "move the needle" at each phase: Phase Goal What Works Phase I Making something people want Unscalable things: manual recruiting, guest posts, talks, direct outreach, targeting blogs Phase II Marketing something people want The leaky bucket is plugged. Pour traction in. SEO, SEM, content marketing, email, ads Phase III Scaling growth Optimize and scale what's working. Layer on additional channels. Phase Channel Map Critical Path A single Traction Goal (e.g., "1% search market share" or "$100K MRR"), then an ordered list of absolutely necessary milestones with dependencies. Every activity is judged against the critical path: "If it is not on the path, don't do it." Channel Summaries 1. Viral Marketing Six loop types: word of mouth, inherent (product usage exposes non users), collaboration (multi user features), embedded (signatures, badges), incentivized (referral rewards), social broadcasts (auto sharing). Math: Viral coefficient K = invites sent per user x conversion rate. K 1 = exponential growth. Even K 0.5 significantly amplifies other channels. Critical insight: Viral cycle TIME matters more than K. YouTube's cycle time is minutes (watch, share, watch). If your cycle time is weeks, even K 1 is slow. 2. Public Relations The filter up media chain: Small forums (HN, reddit) mid tier blogs (TechCrunch, Lifehacker) major outlets (NYT, CNN). Don't pitch the top. Pitch the small site that the top reads. Use HARO (Help A Reporter Out) to respond to journalist queries. Build reporter relationships before you need them. 3. Unconventional PR Two types: publicity stunts (engineered spectacles) and customer appreciation (small, scalable acts of kindness). WePay dropped a 600 pound block of ice with frozen money at PayPal's dev conference. Dollar Shave Club's $5K video got 12K customers in 2 days the same reach as Gillette's $60M annual budget. 4. Search Engine Marketing (SEM) Only works when existing search demand exists. Long tail keywords + negative keywords. Quality Score is primarily driven by CTR. Benchmark: ~$250 spend gives a rough channel read. Average AdWords CTR ~2%. 5. Social & Display Ads Demand generation (creating awareness) vs. demand harvesting (capturing existing intent). Social ads work best when you amplify what's already getting organic traction. 6. Offline Ads Remnant inventory (unsold ad space) can be negotiated up to 90% off rate card. DuckDuckGo's $7K/month San Francisco privacy billboard doubled their userbase that month. 7. Search Engine Optimization (SEO) Two strategies: Fat head (top 18.5% of search volume, direct category terms) and Long tail (70% of volume, specific multi word queries). Validate fat head terms with AdWords first. Content + links. Stay white hat. 8. Content Marketing Takes ~6 months minimum to gain traction. Feeds 8 other channels. HubSpot gets 70 80% of leads from content vs. 10% industry average. Inbound leads cost half as much and close 100% better. 9. Email Marketing For acquisition, engagement, retention, revenue, AND referrals. Lifecycle emails keyed to drop off points. Patrick McKenzie: email subscribers were 70x more likely to buy than other leads. 10. Engineering as Marketing Build free tools as permanent marketing assets. HubSpot's Marketing Grader: 3M+ sites used. Codecademy's Code Year: 450K signups, nearly doubled userbase. Host on its own SEO friendly domain. 11. Targeting Blogs Best Phase I channel. Find niche blogs your audience reads. Mint acquired 20K pre launch signups through blog outreach, 1M users in 6 months. 12. Business Development BD trades value through partnerships; sales trades dollars for product. Five types: standard, joint ventures, licensing, distribution, supply. Pipeline of 50 100 active prospects. 13. Sales For high priced products. SPIN Selling framework: Situation, Problem, Implication, Need payoff. Funnel: Generate Qualify Close. Every drop off is a blockage to remove. 14. Affiliate Programs $2B+ retail affiliate market. Best for high CAC verticals: financial services, insurance, dating, hosting. Advertiser bears no click risk commission only on clean conversions. 15. Existing Platforms App stores, browser extensions, social platforms, marketplaces. Be early on emerging platforms. AirBnB's Craigslist integration. Evernote's multi platform day one strategy. 16. Trade Shows Best for B2B in compressed time. Outbound (walking the floor) is 3 4x more valuable than inbound (waiting at your booth). Visit as a guest the year before exhibiting. 17. Offline Events Conferences, meetups, parties. Twitter's SXSW 2007: $11K on flat panel screens, tweets jumped 20K/day to 60K/day. "Just about the only money Twitter's ever spent on marketing." 18. Speaking Engagements Best for B2B/enterprise. Two talk doctrine: build two solid talks, reuse with light tweaks. Each slide should be a complete story so a 60 min talk compresses to 20 by removing slides. 19. Community Building Five pillars: establish mission, foster cross connections (member to member, not just member to company), communicate personally, be transparent, ensure quality. DuckDuckGo: every employee was a community member first. Testing Principles Test vs. Optimize Testing answers: "Could this channel work at all?" (2 ads + 2 landing pages, ~$250) Optimizing answers: "How do we maximize this channel?" (A/B tests, landing page iterations, copy refinement) Don't optimize a channel before you've proven it can work. Don't test 40 variations when 4 will give you a signal. The Law of Shitty Click Throughs All marketing strategies decay over time. Andrew Chen Every channel saturates. Banner ads once had 78% CTR. Now: 0.1%. This means: No channel works forever Early movers in a channel have an advantage You must constantly re evaluate (re run Bullseye) Measurement Four things to measure per channel test: 1. Cost per acquisition (CPA) what does one customer cost? 2. Volume how many customers are available? 3. Quality are these the RIGHT customers? 4. Time how long from first touch to customer?
