Foundation skills

Product Marketing Context

Start every marketing project here. Product Marketing Context creates a shared context document — your ICP, positioning, value propositions, competitive landscape — that every other skill can reference automatically. You stop re-explaining your product at the start of every session, and the output from every other skill is grounded in your actual market position rather than generic marketing advice.

Use it once at the start of a new project or when your positioning shifts.

Marketing Psychology

Apply behavioral science to marketing decisions. Marketing Psychology covers anchoring, social proof, loss aversion, scarcity, framing, and the cognitive biases that influence how buyers evaluate options and make decisions. Use it when you need to understand why a conversion element isn’t working, or when you want to apply a specific principle to a headline, pricing page, or onboarding flow.

Marketing Ideas

Generate marketing strategies and tactics when you’re stuck. Marketing Ideas draws on a library of 139 proven marketing approaches organized by category — useful for brainstorming the next initiative, evaluating channel bets, or finding approaches you haven’t tried yet. Use it as a starting point when you know you need to grow but aren’t sure what to try next.

Acquisition

SEO Audit

Diagnose what’s suppressing rankings before building anything new. SEO Audit covers technical SEO, on-page optimization, Core Web Vitals, crawl errors, and indexing issues — the full set of things that can prevent good content from ranking. Use it when traffic drops, when a page isn’t performing despite good content, or as a systematic review before launching a new content programme.

AI SEO

Optimize content to appear in AI-generated answers. AI SEO covers the content structure, entity coverage, and citation patterns that make LLMs — ChatGPT, Perplexity, Google AI Overviews — treat your content as a source worth surfacing. Use it alongside traditional SEO for content you want to capture both organic and AI search traffic.

Schema Markup

Unlock rich results in Google search. Schema Markup handles JSON-LD implementation for FAQ, Product, Article, BreadcrumbList, and other schema types. Use it when you want star ratings, FAQ dropdowns, or breadcrumbs to appear in search results, or when structured data is missing and causing Google to misclassify your content.

Programmatic SEO

Build pages at scale targeting long-tail keywords. Programmatic SEO covers template design, data sourcing, and page generation for integration pages, location pages, comparison pages, and directories. Use it when you have a repeatable keyword pattern and the data to fill templates — the skill handles the architecture and copy framework.

Content Strategy

Plan what to create, not just how to write it. Content Strategy covers topic cluster mapping, keyword prioritization, editorial calendar design, and content gap analysis. Use it before starting a content programme, when you’re not sure what to write next, or when existing content isn’t generating the organic traffic it should.

Site Architecture

Design the page hierarchy, navigation, and URL structure that serves both users and search engines. Site Architecture covers IA planning, internal linking strategy, breadcrumb structure, and the navigation decisions that affect crawlability and topical authority. Use it before building a new site or restructuring an existing one that has grown without a plan.

Paid Ads

Plan paid campaigns across Google, Meta, LinkedIn, and other channels. Paid Ads covers bidding strategy, audience targeting, campaign structure, and optimization decisions. Use it when launching a new paid channel, diagnosing underperforming campaigns, or making budget allocation decisions.

Ad Creative

Generate ad copy at scale. Ad Creative handles headlines, descriptions, primary text, and full ad variations for any platform — and iterates based on performance data. Use it when you need more variations than you can write manually, or when testing messaging hypotheses across multiple audience segments.

Cold Email

Write B2B cold outreach that gets replies. Cold Email covers subject lines, opening lines, body copy, CTAs, personalization frameworks, and multi-touch follow-up sequences. Use it for any outbound prospecting — SDR emails, founder-led outreach, partnership emails, and investor outreach.

Competitor Alternatives Pages

Capture high-intent traffic from buyers evaluating competitors. Competitor Alternatives builds comparison and alternative pages in four formats: singular alternative, plural alternatives, you vs competitor, and competitor vs competitor. Use it to rank for “[Competitor] alternative” and “[Your Product] vs [Competitor]” searches — among the highest-intent queries in any category.

Lead Magnets

Create content offers that convert visitors to subscribers. Lead Magnets covers lead magnet selection, positioning, and distribution — ebooks, checklists, templates, cheat sheets, and content upgrades. Use it when you need something compelling enough to trade for an email address, and you want the offer to be specific enough to attract buyers rather than everyone.

Free Tool Strategy

Plan and build free tools that generate leads and earn backlinks. Free Tool Strategy covers tool selection, positioning, distribution, and the engineering-as-marketing decisions that determine whether a tool builds long-term organic value or fades after launch week. Use it before building a calculator, grader, generator, or other interactive marketing tool.

Conversion

Page CRO

Diagnose and improve conversion rates on marketing pages. Page CRO covers above-the-fold hierarchy, value proposition clarity, social proof placement, CTA friction, and the specific changes most likely to move conversion. Use it on any page that gets traffic but isn’t converting — homepages, landing pages, pricing pages, and feature pages.

Signup Flow CRO

Reduce registration and account creation drop-off. Signup Flow CRO covers field reduction, social login, error messaging, and the step sequencing that gets users to first session without losing them in the form. Use it when signup completion rate is low or when you’re redesigning a registration flow.

Onboarding CRO

Improve activation between signup and first value. Onboarding CRO covers setup checklist design, empty state copy, aha moment identification, and the email triggers that bring users back when they stall. Use it when users sign up but don’t complete setup or don’t return after the first session.

Paywall & Upgrade CRO

Convert free users to paid. Paywall Upgrade CRO covers upgrade modal design, feature gate messaging, trial expiration flows, and the copy that makes the upgrade decision feel obvious. Use it when free-to-paid conversion is low or when you’re designing the upgrade experience for the first time.

Form CRO

Optimize lead capture, contact, and demo request forms. Form CRO covers field ordering, multi-step progression, error handling, and the trust signals that reduce abandonment. Use it on any non-signup form that captures information from potential customers.

Popup CRO

Design exit-intent, scroll-triggered, and announcement popups that convert. Popup CRO covers trigger logic, offer framing, copy, and the targeting rules that show the right message at the right moment without destroying the experience.

A/B Test Setup

Design and run experiments correctly. A/B Test Setup covers hypothesis framing, sample size calculation, statistical significance, and how to read results without calling tests early. Use it before any experiment where you want the data to actually be trustworthy.

Copywriting

Write marketing copy that converts. Copywriting covers homepage copy, landing pages, pricing pages, feature descriptions, headlines, and CTAs. Use it for any page where the text needs to persuade buyers — from the first above-the-fold sentence to the fine print.

Copy Editing

Improve existing copy without rewriting from scratch. Copy Editing is a systematic pass over marketing copy — clarity, specificity, rhythm, and the specific fixes that make good copy great. Use it when you have copy that almost works but needs tightening.

Retention & revenue

Email Sequence

Build automated email flows that nurture, activate, and retain. Email Sequence covers welcome sequences, nurture drips, re-engagement campaigns, and lifecycle triggers. Use it for any multi-email automated flow — from the onboarding series through to the annual renewal reminder.

Churn Prevention

Reduce cancellations and recover failed payments. Churn Prevention covers cancel flows with save offers, exit surveys, dunning sequences for failed payments, and win-back campaigns for churned users. Use it when churn rate is too high or when you’re building the retention infrastructure for the first time.

Referral Program

Design a referral or affiliate program that actually grows. Referral Program covers incentive structure, mechanics design, referral flow, and the measurement setup that tells you whether the programme is working. Use it when you want existing users to bring in new customers through word of mouth.

Pricing Strategy

Make better pricing decisions. Pricing Strategy covers pricing tier design, value metric selection, freemium vs free trial trade-offs, annual vs monthly packaging, and the research methods — Van Westendorp, conjoint analysis — that tell you what the market will actually pay.

Operations

Analytics Tracking

Instrument the tracking that makes attribution possible. Analytics Tracking covers GA4 event schema, GTM configuration, UTM conventions, funnel instrumentation, and the conversion tracking that connects marketing spend to revenue. Use it when you’re setting up tracking from scratch or when existing tracking is unreliable.

Revenue Operations

Connect marketing to sales to revenue. RevOps covers lead scoring models, lifecycle stage definitions, routing rules, pipeline stages, and the CRM automation that ensures qualified leads reach the right rep at the right time. Use it when leads are falling through the cracks or when marketing and sales are measuring different things.

Sales Enablement

Build the collateral that helps sales close. Sales Enablement covers pitch decks, one-pagers, objection handling guides, demo scripts, and ROI analyses. Use it when your sales team needs something to send, show, or say — and what they currently have doesn’t reflect your actual positioning.

Launch Strategy

Plan product and feature launches. Launch Strategy covers announcement timing, channel sequencing, audience warm-up, and the execution coordination that generates spikes in signups or press coverage. Use it before any public release — from a new product to a significant feature update.

Social Content

Create social media content consistently. Social Content handles LinkedIn posts, Twitter/X threads, Instagram content, TikTok scripts, and content repurposing across platforms. Use it when you need to produce platform-specific content at a pace that keeps your audience engaged.

Marketing Ideas

Generate marketing strategies when you’re stuck. Marketing Ideas provides 139 proven approaches across channels and tactics — demand gen, product-led growth, community, content, partnerships, and more. Use it when you’ve exhausted your current playbook and need inspiration for what to try next.
