Best Claude Skills for Marketing (2026)

Ranked by SkillProof Score · how we score
- 1
Copywriting
Conversion copywriting for marketing pages -- headline/CTA formulas, an explicit weak-vs-strong CTA blacklist, and structured output with rationale.
From our test: A baseline pass on the mini-task produced a headline and CTA ('Manage Your Projects Better' / 'Get Started') that land exactly on the two anti-patterns the skill's own Weak CTAs / vague-language…
- 2
A/B Testing
Designs statistically valid experiments and runs a full ICE-scored experimentation program.
From our test: Follows its own peeking rule to the letter: given a fake 3-day result with 95% confidence, it refused to call a winner and cited regression-to-the-mean and day-of-week effects rather than declaring…
- 3
Content Strategy
Plans topic clusters, content pillars and a weighted-priority editorial calendar grounded in buyer stage.
From our test: Replaced a flat blog-topic brainstorm with buyer-stage-mapped clusters and a weighted 40/30/20/10 scoring table for prioritization — the one weak spot is references/headless-cms.md, whose CMS…
- 4
Substack Ghostwriting & Content Optimization
Substack-specific ghostwriting and growth workflow: voice guide, algorithm, monetization.
From our test: It's a Substack-specific growth/ghostwriting workflow (algorithm mechanics, Notes strategy, monetization math), not a generic newsletter tool — and Phase 1 is a hard stop: it produced five…
- 5
MD2WeChat Lite
Wraps the md2wx CLI to turn Markdown into themed WeChat Official Account drafts.
From our test: Cross-checked the documented article-draft flags against the actual Go source and every flag name matched exactly, including the easy-to-miss 'no stdin' and 'cover-image must be a public URL' caveats…
- 6
Business Profile Creator
Guided 20-question interview that turns raw business info into a structured JSON brand profile.
From our test: Fed it a fictional Etsy pet-planner brand: the guided interview produced a complete 20-field JSON profile (mission, differentiators, CTAs, platforms) versus a 40-word unstructured paragraph from an…
- 7
Gtm Positioning
Fletch-framework playbook for B2B positioning, GTM type, and website copy blocks.
From our test: Ran a real homepage-copy task through it: the skill version named a positioning strategy and awareness stage before writing a line, then produced a hero block with concrete numbers (30-to-10-minute…
- 8
Kling AI Video Generation
Writes model-aware Kling AI video prompts - image/text-to-video, avatars, multi-shot, voice control - sourced to official release notes.
From our test: Asked for a 5s social-loop prompt from a dog photo: the baseline re-described the whole already-visible scene and defaulted to generic '4K, high quality' boilerplate, while the skill version wrote a…
- 9
Brand Lock Extractor
Turns a site, PDF, or screenshots into a sourced brand-lock.md with confidence flags on every value.
From our test: Fed it a real site excerpt (CSS custom props + copy); the baseline free-hand pass fabricated a hex (#F5F0E8) and two font names never present anywhere in the source, exactly the failure this skill's…
- 10
Blog To Social
Turns one finished blog post into platform-native Facebook, X and LinkedIn drafts in a single pass, with hard length and hashtag rules.
From our test: Ran it against a sample CI-speedup blog post: the unconstrained baseline X post came out to 282 characters (over the platform's own 280 limit) and reused the same '14-to-3-minutes' stat as the lead…
How this ranking works
Each skill gets a fresh install in Claude Code, three trigger phrasings, and the same task run with and without it. Scores: installation (5), trigger reliability (5), output vs baseline (10), documentation honesty (5) — normalized to a 10-point SkillProof Score. Full rubric on the methodology page. Queue-verdict skills sit at the bottom until testing completes.
