The Ultimate AI Prompt Library for Marketing Teams [100+ Prompts]

The difference between mediocre AI output and great AI output is the prompt.

Most marketers type something vague. "Write me an ad." Then they get generic results and blame the AI. But the problem isn't the tool. It's the instruction.

An AI prompt library solves this. Instead of starting from scratch every time, you pull a proven prompt, customize it, and get consistent quality.

This guide gives you 100+ battle-tested prompts organized by marketing function. Copy them. Customize them. Build your own library from what works.

Why Every Marketing Team Needs a Prompt Library

Prompts are reusable assets. Write a good one once, use it forever.

Consistency across the team. When everyone uses the same prompts, output quality stays consistent. No more "Sarah gets great results from AI, but Mike's outputs are unusable."

Speed. Starting from scratch wastes time. With a prompt library, grab what you need and go.

Onboarding. New team members produce quality work on day one using proven prompts. No learning curve.

Compound improvement. Every time someone improves a prompt, the whole team benefits. Good prompts get better over time.

Institutional knowledge. Prompts capture what works for your brand, your audience, your voice. That knowledge doesn't leave when people do.

The teams getting the most from AI aren't the ones with the best tools. They're the ones with the best prompts.

How to Use These Prompts

These are templates. For best results:

Replace the brackets. Anywhere you see [brackets], add your specific information. Product name, audience, tone.

Add context. The more relevant detail you provide, the better the output. Include target audience, product features, brand voice guidelines.

Iterate. If the first output isn't perfect, refine the prompt. Ask for variations. Request specific changes.

Save your winners. When a prompt consistently produces great results, save it with notes on how to use it.

Prompt Engineering Best Practices

These tips improve any prompt.

The CRAFT Framework

C - Context: Give background. What's the situation? What do you already have?

R - Role: Tell the AI what perspective to take. "You are a conversion copywriter" beats "write copy."

A - Action: Be specific about what you want. "Write 5 headlines" beats "help with headlines."

F - Format: Define the output structure. Bullet points? Numbered list? Specific length?

T - Tone: Set the voice. Casual? Formal? Playful? Match your brand.

Common Mistakes

Too vague: "Write an ad for my product"

Better: "Write a Facebook ad primary text for [product] targeting [audience] with a [tone] voice. Focus on [key benefit]. Under 125 characters."

No context: Asking for output without explaining who it's for or why.

Better: Always include target audience and desired outcome.

No format: Letting AI decide length and structure.

Better: Specify "3 variations," "under 50 characters," "bullet points."

Iteration Prompts

When output needs improvement:

• "Make it more conversational"

• "Shorten this by 50%"

• "Add more specific details"

• "Remove the jargon"

• "Give me 3 more variations in a different style"

• "Make the CTA more action-oriented"

Building Your Own Prompt Library

These prompts are a starting point. Here's how to build a library for your team.

Start with what you use most. If you write ads daily, build your ad prompt collection first.

Test and iterate. Run each prompt 5-10 times. Keep versions that consistently produce good output.

Add context templates. Create fill-in-the-blank sections for your specific products, audiences, and brand voice.

Organize by function. Ads, email, social, SEO, analytics. Make prompts easy to find.

Document what works. Add notes: "This works best for B2B" or "Add specific numbers for better output."

Review quarterly. AI capabilities change. Prompts that needed heavy editing six months ago might work perfectly now.

Common Questions

Do I need different prompts for different AI tools?

Core prompts work across Claude, ChatGPT, and other models. You might tweak for specific strengths, but fundamentals transfer.

How do I maintain brand voice with AI?

Add voice guidelines to every prompt. Better yet, create a "brand voice prompt" that you paste at the start of sessions.

Should AI write all my marketing copy?

No. Use AI for first drafts, variations, and ideation. Add human judgment for strategy, brand fit, and final polish.

How do I know if a prompt is good?

A good prompt produces output that needs minimal editing and works consistently. If you're rewriting 80% of the output, the prompt needs work.

Can I share prompts across my team?

Yes. That's the point. A shared prompt library means consistent quality regardless of who's using it.
