Design a 20-week learning path for {{target_audience}} to go from self-paced online to intermediate in digital marketing. Use a {{tone}} tone. Include:
- Learning path overview with starting point, destination, time, and milestones
- 4 phases: Foundation (Weeks 1-4), Skill Development (Weeks 5-10), Advanced Application (Weeks 11-16), Mastery (Weeks 17-20) — each with topics, resources, practice activities, and milestone checks
- Weekly schedule template (Mon-Fri study, weekend review, buffer time, accountability)
- Progress tracking tools (skills checklist, reflection prompts, review template, rewards)
Output as numbered steps with action title, instructions, expected outcome, and pitfalls. Max 1300 words. Every recommendation must be specific to digital marketing and {{target_audience}}. Use plain language. Skip any section if information is unknown.
