11 best Claude skills for marketing and content (2026)

AI Tool Garage editors·

Agent skills aren't only for developers. Some of the most useful ones encode marketing know-how: how to structure a landing page, run a fair A/B test, or turn ad data into budget decisions. Install them in Claude (the app or Claude Code) and you get the method every time, instead of re-explaining it in each chat. We picked these eleven from nearly 300 marketing and content skills in our directory.

Experiments and paid ads

Most A/B tests fail because they stop too early or test too many things at once. Most ad accounts waste money because nobody makes the cut-or-scale call. These skills bring the statistics and the decision rules.

How to use these skills without a terminal

  1. Download the skill's ZIP from its page here.
  2. In the Claude app go to Settings → Capabilities → Skills and upload the ZIP.
  3. Ask for the task normally, such as “write a landing page for our new plan”. Claude picks up the skill when the request matches.

Start with Copywriting and Brand Voice: you'll notice the difference in the first draft. Add the A/B and ad skills when you have real data to feed them.
