Claude marketing skills: the best collections and how to use them with real data

Ask Claude for landing page copy without any context and you get competent, generic copy. Give it a skill that encodes how a good conversion copywriter works (the research questions, the structure, the objections to answer) and the result is noticeably better. Give it that skill and your actual campaign and analytics data, and it stops giving advice and starts doing analysis.

This guide covers the best marketing skill collections, how to install them, and how to combine them with live data. For how skills work in general, see Claude skills explained.

Repositories and install commands were checked on GitHub on 6 October 2026.

The main collection: marketingskills

coreyhaines31/marketingskills is the most widely used marketing skill collection by a distance. It is MIT-licensed and contains around fifty skills:

Install all of it, or only what you use:

npx skills add coreyhaines31/marketingskills
npx skills add coreyhaines31/marketingskills --skill cro copywriting

Or as a Claude Code plugin:

/plugin marketplace add coreyhaines31/marketingskills
/plugin install marketing-skills

Install a subset. Fifty skills means fifty descriptions in Claude's context, and several overlap (copywriting and copy-editing, ads and ad-creative). Pick the five to ten that match work you do every month.

Alternatives

If you mainly run paid search and social, a paid-media collection fits better than the general one. For writing, add a style skill such as humanizer to strip the AI tells from final copy.

Skills give know-how. MCP gives the numbers.

This is the part most marketing skill tutorials skip. A skill like seo-audit knows how to audit a site. Without data, it audits what you paste in, or what it can fetch from a public page. The useful version reads your own sources:

With both in place, requests change character:

• "Run a CRO review of our pricing page" becomes a review that cites the page's actual conversion rate and drop-off from GA4.
• "Find SEO quick wins" becomes a list of your pages ranking 8 to 20 in Search Console, with the queries and impressions behind each.
• "Audit our Google Ads" becomes an audit of last month's search terms, with the ones that spent money without converting.

Write your own for the recurring work

The collections cover general marketing craft. What they cannot know is your plan, your targets and your reporting format. That is where your own skill pays off.

We run our own weekly SEO review this way: a skill that knows our SEO plan, our targets per quarter and where the progress log lives, pulls Search Console, Ahrefs and Google Ads through MCP, and writes the same brief every Monday: what changed, what is behind target, and the one or two actions for the week. The procedure lives in the skill, the data comes from MCP, and the history lives in a log file in the repository.

skill-creator is the fastest way to build a skill like that, and it tests it against a baseline so you know it helps.

A setup that works for a marketing team

1. Pick five to ten skills from one collection, matching recurring work: copywriting, CRO, SEO audit, ads, analytics.
2. Connect the data: Search Console, GA4, the ad platforms and your CRM through MCP, read-only to start.
3. Write one skill of your own for the recurring report everyone already does by hand.
4. Keep it consistent: the same skills and the same connections for the whole team, so two people asking the same question get the same answer.

The last step is the hard one with per-person setups. Walma AI Hub distributes approved skills and MCP connections to the whole marketing team under one policy, with every call logged, inside the customer's own EU region. The marketing-specific version is on AI for marketing.
