Claude marketing skills are instruction packs that teach an agent how to do marketing work the way your team does it: audit a landing page, write copy against a brief, review a Google Ads account, plan an email sequence. We have reviewed 23: nine get an install verdict, twelve come with caveats and two we tell you to skip.
What Claude marketing skills do for a marketing team
A skill is a folder with a SKILL.md file. According to the Claude Code docs, Claude keeps each skill’s description in context and loads the full instructions only when a task matches. That suits marketing, where one team may need a dozen repeatable workflows across channels, each with its own rules.
Most marketing skills are Markdown only. They give the agent a method, a set of reference playbooks and sometimes eval prompts. They do not supply data. Keyword volumes, ad spend and analytics come from your own accounts, which is where the risk sits.
Why a generic assistant falls short
Ask a chat assistant for homepage copy and you get fluent, generic text. A good skill changes the process. It asks about the product and audience first, drafts under rules against vague claims, and flags missing data instead of guessing. Corey Haines’ Marketing Skills builds every skill around a shared product-marketing context file, so brand voice and positioning are written down once.
The same pack shows how far one library can reach across channels. Its 52 skills include conversion optimization, SEO and programmatic SEO, schema, paid ads and ad creative, cold email and email sequences, analytics and conversion tracking, A/B testing, pricing, onboarding, launch and referrals. Every skill reads the shared context file first, so you do not re-explain the product, the audience or the positioning each time. For a small marketing team, that one file is the real saving.
Three best starting use cases
If you are getting started, begin where the output is easy to check:
- A site audit: crawlability, indexation, speed and on-page issues, ending in a ranked action plan.
- Landing page copy: a first draft from real product facts, reviewed by a person.
- A paid media audit: reading exported campaign data and listing wasted spend, with no changes to the account.
Each is a sensible starting point because a mistake costs you an edit, not a budget.
Connecting live data
Some skills work with Meta Ads, Google Ads or GA4 through MCP, a standard that lets Claude Code connect to external tools and data sources. The official MCP docs tell you to verify that you trust each server before connecting it. For ad accounts, start with read-only access. The ads skill below gives the same advice. See skills vs MCP for the difference.
What to look for before installing
Check depth: a 30 KB skill with 16 playbooks and evals is a different product from a one-page prompt. Check dependencies and keys. Check whether the pack lists sponsored tools, which Corey Haines’ README discloses. Read the security status: of the 23 skills, 3 are clean, 17 are marked “review” and 3 have broad access. The labels are explained on the security page.
Recommended marketing skills
- Marketing Skills (Corey Haines) is the main pack: 52 skills for CRO, copywriting, SEO, analytics and ads, with reference folders and about 40 eval files. It has about 4.6 million recorded installs. Status: review. Its optional integrations use API keys you supply, and some commands run unpinned
npxtools. - copywriting is clean. It diagnoses your input first, then drafts under rules against AI-sounding phrasing and unsupported claims. It has a 15.5 KB
SKILL.md, three reference files and ten eval prompts, but no scripts. - ads covers Google, Meta and LinkedIn with 16 reference playbooks, and it is clean. It labels missing data and advises read-only account access.
- Claude Ads audits 12 ad platforms with per-platform skills. It is read-only by default and requires approval for changes, but it needs Python and optional rendering tools.
- NotFair Plugin has 48 skills with live-data workflows through a hosted connector. It can change ad accounts and WordPress after your approval, so connect only accounts you are willing to expose.

Skills to avoid
Two repositories carry a skip verdict. Wonda CLI requires a paid plan, runs a stealth automation browser against your logged-in LinkedIn, X and Reddit accounts, and by default backs up session cookies to the vendor’s server. The anbeime skill store is a mirror of other authors’ work with an unclear license; its Chrome automation skill pre-approves any shell command and copies your real Chrome profile, cookies and logins included. Install the originals instead.
Amazon Skills by Nexscope is not a skip, but read the caveats: it is mostly prompts without data behind them, with a fee calculator on 2024 rates and scripts that scrape Amazon pages.
Building your own marketing skill
If no pack fits your brand, write a small one. A folder, a SKILL.md with a name and description, and your voice rules are enough. Our guide to creating a Claude skill walks through it, and the category page lists everything we reviewed.
