Workflow
Step 1: Diagnose Stage & Resources
Ask: "Where are you in your marketing journey?"
| Stage | Signals | Focus | |-------|---------|-------| | Pre-launch | Building product, no users | → Brand foundation, pre-launch content | | Early-stage | For [target customer] who [need/pain], [Product] is a [category] that [key benefit]. Unlike [alternatives], we [differentiator].
Brand Voice Dimensions:
Define where you sit on each spectrum:
| Dimension | ← One End | Other End → | |-----------|-----------|-------------| | Tone | Formal | Casual | | Attitude | Serious | Playful | | Language | Technical | Simple | | Emotion | Reserved | Enthusiastic |
Brand Voice Examples by Company Type:
| Company Type | Voice Characteristics | Examples | |--------------|----------------------|----------| | Dev tools | Technical, direct, no fluff | Stripe, Vercel, Linear | | Consumer | Friendly, emotional, relatable | Airbnb, Duolingo, Spotify | | B2B SaaS | Professional, helpful, clear | Salesforce, HubSpot, Slack | | Fintech | Trustworthy, simple, reassuring | Wise, Ramp, Mercury |
Step 3: Content Strategy
Use references/content-strategy.md for detailed playbook.
Content Pillar Model:
Choose 3-5 pillars that connect your expertise to customer problems:
| Pillar Type | Description | Example (Figma) | |-------------|-------------|-----------------| | Product-adjacent | Topics your product helps with | "Design systems" | | Industry trends | What's changing in your space | "Future of design collaboration" | | Customer success | How customers win | "Design team workflows" | | Thought leadership | Your unique POV | "Why design is a team sport" |
Content Format Selection by Stage:
| Stage | Primary Formats | Why | |-------|-----------------|-----| | Early (0-1K users) | Long-form blog, Twitter/LinkedIn threads | SEO foundation, founder voice | | Growth (1K-10K) | + Newsletter, templates/tools | Capture emails, provide value | | Scale (10K+) | + Podcast, video, webinars | Brand building, multi-channel |
Content Distribution (80/20 Rule):
Spend 20% creating, 80% distributing:
| Channel | Best For | Effort | |---------|----------|--------| | Owned (blog, newsletter) | SEO, owned audience | Medium | | Social (Twitter, LinkedIn) | Reach, engagement | Low per post | | Communities (Reddit, Slack, Discord) | Trust, niche reach | High (relationship-based) | | Syndication (Medium, Dev.to, HN) | Extended reach | Low |
Content Repurposing Workflow:
1 piece of pillar content → 10+ distribution pieces:
Long-form blog post
├── Twitter thread (key takeaways)
├── LinkedIn post (professional angle)
├── Newsletter section
├── Reddit comment (when relevant)
├── Quora answer
├── Slide deck (SlideShare)
├── Short video (key point)
├── Infographic (data/stats)
├── Podcast talking points
└── Community discussion starter
Step 4: SEO Foundation
Use references/seo-playbook.md for detailed process.
SEO Priority by Stage:
| Stage | SEO Focus | Time Investment | |-------|-----------|-----------------| | Pre-launch | Keyword research, site structure | 5% of marketing time | | Early | 1-2 pillar pages, blog foundation | 20% of marketing time | | Growth | Content clusters, link building | 30% of marketing time | | Scale | Technical SEO, programmatic | 25% of marketing time |
Keyword Research Framework:
| Keyword Type | Intent | Funnel Stage | Example (Project Management Tool) | |--------------|--------|--------------|-----------------------------------| | Problem-aware | Informational | Top | "how to manage remote team" | | Solution-aware | Comparison | Middle | "best project management software" | | Product-aware | Transactional | Bottom | "asana vs monday" | | Brand | Navigational | Bottom | "[your brand] pricing" |
Quick SEO Wins (First 90 Days):
- Homepage optimization — Clear H1, meta description, target keyword
- Create 3-5 pillar pages — Comprehensive guides for main keywords
- Blog cadence — 2-4 SEO-optimized posts per month
- Technical basics — Fast load time, mobile-friendly, sitemap submitted
- Internal linking — Connect all content to pillar pages
Content-Led SEO Benchmarks:
| Metric | 6-Month Target | 12-Month Target | |--------|----------------|-----------------| | Organic traffic | 1,000-5,000/month | 10,000-50,000/month | | Ranking keywords | 100-500 | 500-2,000 | | Domain authority | 20-30 | 30-45 | | Backlinks | 50-200 | 200-1,000 |
Step 5: PR & Media Relations
Use references/pr-outreach.md for templates and process.
When to Pursue PR:
| ✅ Good Time for PR | ❌ Bad Time for PR | |---------------------|-------------------| | Funding announcement | No news hook | | Major product launch | Early MVP stage | | Significant milestone (users, revenue) | "We exist" story | | Unique data/research | Copycat product | | Counter-narrative story | No media relationships |
PR Tier Strategy:
| Tier | Publications | Approach | Timeline | |------|--------------|----------|----------| | Tier 1 | TechCrunch, WSJ, NYT | Exclusive offer, strong hook | 2-4 weeks lead | | Tier 2 | Industry pubs, Forbes contributors | Targeted pitch | 1-2 weeks lead | | Tier 3 | Blogs, newsletters, podcasts | Direct outreach, easier access | 1 week lead |
Press Pitch Structure:
Subject: [Specific hook] — [Company] [achievement/news]
Paragraph 1: The news (who, what, when, why it matters)
Paragraph 2: Context (why now, market trend, problem being solved)
Paragraph 3: Proof points (traction, customers, investors)
Paragraph 4: Offer (exclusive, interview, assets available)
One line: Founder bio + contact
Pitch Timing Best Practices:
- Tuesday-Thursday, 7-9 AM journalist's timezone
- Avoid Mondays (backlog) and Fridays (weekend mode)
- Embargo dates: Offer 1-2 week exclusive for major news
- Follow up once after 3-5 days, then move on
Step 6: Community Building
Use references/community-playbook.md for detailed playbook.
Community Platform Selection:
| Platform | Best For | Effort Level | Control | |----------|----------|--------------|---------| | Slack/Discord | Real-time, engaged users | High | High | | Circle/Geneva | Structured community, courses | Medium | High | | Reddit | Organic discovery, niche topics | Medium | Low | | Twitter/X | Public conversation, reach | Low | Low | | LinkedIn Groups | B2B professional audiences | Low | Medium |
Community Strategy by Stage:
| Stage | Focus | Tactics | |-------|-------|---------| | Seed (0-100 members) | Quality over quantity | Personal invites, hand-pick members | | Build (100-1,000) | Establish norms, rituals | Welcome flow, weekly threads, AMAs | | Grow (1,000-10,000) | Delegate, scale programs | Moderators, champions, events | | Scale (10,000+) | Systematize, segment | Tiers, sub-communities, ambassadors |
Community Engagement Tactics:
| Tactic | Frequency | Purpose | |--------|-----------|---------| | Welcome messages | Every new member | Activation | | Discussion prompts | 2-3x per week | Engagement | | AMAs / Office hours | Weekly/biweekly | Value, access | | Member spotlights | Weekly | Recognition | | Exclusive content | Monthly | Retention | | Events (virtual/IRL) | Monthly/quarterly | Connection |
Community Health Metrics:
| Metric | Healthy Range | Warning Sign | |--------|---------------|--------------| | DAU/MAU | > 20% | 48 hours | | Member-generated content | > 50% of posts | 10% |
Step 7: Channel Prioritization
Channel Selection by Business Type:
| Business Type | Primary Channels | Secondary Channels | |---------------|------------------|-------------------| | B2B SaaS | LinkedIn, SEO/blog, community | Twitter, newsletter, PR | | Dev Tools | Twitter, GitHub, technical blog | Reddit, HN, Discord | | Consumer | TikTok/Instagram, SEO, PR | Twitter, community, influencers | | Marketplace | SEO, supply-side community | PR, local marketing | | Fintech | SEO, trust content, PR | LinkedIn, partnerships |
Channel Evaluation Framework:
Score each channel 1-5:
| Factor | Question | |--------|----------| | Audience fit | Is your target customer here? | | Content fit | Does your content work on this channel? | | Competition | How saturated is it? | | Founder fit | Do you enjoy/excel at this channel? | | Resource fit | Can you sustain it with current resources? |
Focus Rule: Master 1-2 channels before adding more. Mediocre presence on 5 channels < excellent presence on 2.
