A slash command that writes Google search ad copy within character limits and exports a CSV

Tools:
Claude Code, Claude Skills
Who it's for

Founders and small teams running Google search ads who refresh copy often

What they report

Anthropic says growth marketer Austin Lau cut ad creation time from 30 minutes to 30 seconds with Claude Code workflows, including a Google Ads copy workflow that outputs 15 headlines and 4 descriptions per ad into an upload-ready CSV. Every file still gets manual review before upload.

Example

Lau types /rsa. Claude asks for campaign data, existing copy and keywords, checks the output against Skills for brand voice, product accuracy and responsive search ad best practices, then builds the CSV.

How to do it

  1. Write a short brand voice file and a list of approved product claims.
  2. Create a saved command or project instruction for responsive search ads.
  3. Feed it campaign performance data, current copy and keywords.
  4. Go back and forth on headlines until they fit your audience.
  5. Export to CSV, review by hand, then upload.
