How to Write Prompt for AI Tools

How to Write Prompt for AI writing tools is simple: treat AI like your fastest intern and give it a clear brief.

A strong prompt tells the AI who it is (role), what you want (goal), who you’re talking to (audience), where this will be used (context), what shape you need (format), how it should sound (style), and what to avoid (limits).

Meet Riya, a digital marketer at a small agency.

She runs Meta ads, writes emails, plans content calendars, and reports on CTR and CPL every week.

Like everyone else in 2025, she “discovered” AI writing tools.

• ChatGPT for blogs
• Gemini for ideas
• Jasper for ads
• Claude for emails

Her logic was simple:

“I’ll give AI a topic. AI will give me magic. I’ll go home early.”

So one day, while creating a campaign for a new skincare brand, she typed:

“Write Facebook ad copy for a skincare product.”

And AI replied:

“Say goodbye to dull skin!
Try our amazing skincare product for glowing, radiant skin.
Shop now!”

She used it.
The ad went live.

Result?

• CTR was average
• Cost per lead was high
• The copy sounded like every other skincare ad on the planet

Her boss looked at the dashboard and said:

“Riya… you are using AI. But your ads still sound like copy-paste. Where is our brand? Insight is missing from your ads.

Riya felt something was wrong.
Not with AI…
With the way she was talking to AI.

That’s when she learned the real game:
AI is not a magician.
AI is a very fast junior copywriter.

And juniors need good briefs.

AI is your fastest intern, not your creative director

I asked Riya:

“If you hired an intern and told them:
‘Write ad copy for skincare product’
what would happen?”

She laughed:

“They’d freeze. Or write something super generic.”

Exactly.

But if she told that intern:

• Who the audience is
• What the product does differently
• What stage of funnel this ad is for
• What tone to keep
• What NOT to say

…then suddenly that intern would produce something much better.

AI works the same way.

Weak brief → weak output
Strong brief → strong output

Most digital marketers think:

“My prompts are fine. The tool is the problem.”

But in 90% cases, the prompt is trash.
Too short. Too vague. No context.

So AI cannot give you:

• Strong hooks
• On-brand tone
• Clear messaging for each funnel stage
• Local flavour for your audience

Because you never told it what you wanted.

The real problem with Riya’s prompts

Let’s read her original prompt again:

“Write Facebook ad copy for a skincare product.”

What’s missing?

• Which platform exactly? (Meta / Instagram)
• Awareness, consideration, or retargeting?
• Who is the ideal customer?
• What problem are they struggling with?
• What is the main promise?
• What brand voice?
• Single line or long copy?
• Any words to avoid?

The AI had zero direction.

So it wrote what it had seen a million times:
“glowing skin”, “radiant”, “buy now”, “try today”.

Not wrong.
Just invisible.

This is the pain every digital marketer feels:

• AI saves time, but you spend more time rewriting
• Everything sounds the same
• No brand personality
• You feel guilty showing that copy to clients

So I showed Riya a simple framework.

The 7-part how to write prompt formula

I wrote this on her notepad:

ROLE + GOAL + AUDIENCE + CONTEXT + FORMAT + STYLE + LIMITS

This is your AI brief.
Not just for one tool – for ChatGPT, Gemini, Claude, Jasper, Copy.ai and others.

Let’s break it down with examples from Riya’s daily work.

ROLE – Who should the AI become?

Don’t talk to a blank robot.
Make it step into a role.

For example:

• “You are a performance marketer specializing in Meta ads.”
• “You are a brand copywriter for premium skincare.”
• “You are an email marketer writing for D2C beauty brands in India.”

Now AI knows how to think.

For Riya’s skincare ad we wrote:

“You are a senior performance marketer writing Meta ad copy for a premium skincare brand.”

Instant shift.

GOAL – What exactly do you want?

You are not just “writing copy”.
You are trying to move a metric.

Examples of goals:

• “Increase click-through rate for cold traffic.”
• “Retarget add-to-cart users and push them to purchase.”
• “Get newsletter signups from first-time visitors.”
• “Drive leads for a webinar from warm followers.”

For Riya, her goal was:

“Goal: Write primary text + headline for a cold audience ad that makes women curious enough to click and explore the product.”

That’s very different from “Write ad copy”.

AUDIENCE – Who are we talking to?

This part is gold for marketers.

Don’t just say “women” or “youth”.
Describe them like a persona.

For example:

“Audience: Women in India, age 24–35, working professionals, who have tried multiple skincare brands. They are tired of fake ‘glow’ claims and want something safe, simple, and science-backed.”

Now AI can:

• Pick the right pain points
• Choose the right words
• Avoid childish tone

Same logic for B2B:

“Audience: B2B SaaS founders who are drowning in tools and hate fluffy marketing talk.”

The more real your audience description, the better the copy.

CONTEXT – Where will this be used?

Context answers:

• Which channel?
• What funnel stage?
• What campaign?

For example:

“Context: This is a cold audience ad on Instagram and Facebook. People have never heard of our brand. The goal is not to sell immediately, but to make them stop scrolling and click through to learn more.”

Or for email:

“Context: This email will go to trial users who signed up 7 days ago but have not used the product. We want to nudge them to log in again.”

Context tells AI how hard to push, and how much to explain.

FORMAT – How should the output look?

As marketers, you already think in formats:

• Ad primary text
• Ad headline
• Description
• Email subject line + body
• Landing page sections
• Social carousel slides
• Hooks for Reels

So tell AI the exact shape.

For Riya’s ad, we wrote:

“Format:

• 3 options for primary text (under 60–80 words each)
• 3 options for headlines (under 40 characters)
• 3 short descriptions (under 60 characters)
• Put them in a simple list.”

No guessing.
AI now knows what to output.

STYLE – How should it sound?

This is where brand voice comes in.

Examples:

• calm, premium, reassuring
• fun, playful, Gen Z-ish
• bold, no-nonsense, direct

For skincare, Riya chose:

“Style: Warm, trustworthy, and slightly conversational. No over-the-top drama. Speak like a dermatologist friend, not a sales rep.”

So AI won’t scream:
“OMG GIRL YOU NEED THIS NOW!!!”

It will talk like a human.

LIMITS – What must it avoid?

Very important in marketing.

Examples:

• No fake guarantees
• No medical claims
• No use of banned words (e.g. “whitening”)
• No emojis if brand is minimal
• No cheesy lines like “revolutionary”, “game-changer”, etc.

For Riya’s prompt:

“Limits: Do not make medical claims. Don’t promise instant results. Avoid words like ‘whitening’ or ‘fair’. Don’t use more than 2 emojis per option.”

Now AI has guardrails.

Before vs After: Skincare ad example

❌ Weak prompt

“Write Facebook ad copy for a skincare product.”

➡ Output: same old “glowing skin” nonsense.

✅ Strong prompt (for digital marketer)

“You are a senior performance marketer writing Meta ads for a premium skincare brand.

Goal: Create cold audience ad copy that makes women curious enough to click and learn more about our new product.

Audience: Women in India, age 24–35, working professionals who struggle with dull, tired-looking skin because of long hours and pollution. They have tried many products with big promises and are now skeptical.

Context: This is a cold ad for Instagram and Facebook feeds. Objective is traffic, not direct purchase. We want them to think: ‘Hmm, this looks different. Let me check it out.’

Format:

• 3 options for primary text (60–80 words each)
• 3 options for headlines (under 40 characters)
• 3 short descriptions (under 60 characters)

Style: Warm, trustworthy, and conversational. Speak like a knowledgeable friend, not a sales brochure.

Limits: No medical claims, no ‘whitening’ language, no fake guarantees, max 2 emojis per option.”

Now any AI writing tool will give you:

• Varied angles
• Better hooks
• Safer, sharper messaging

Still not perfect.
But miles ahead of your one-liner.

Other real use cases for digital marketers

Let’s apply the same formula to different tasks you handle daily.

Email nurturing sequence

❌ Weak:

“Write an email sequence for my SaaS product.”

✅ Strong:

“You are an email marketer for a B2B SaaS tool.
Goal: Create a 3-email onboarding sequence for users who just signed up for a free trial of our project management software.
Audience: Startup founders and small agency owners who are busy and hate long emails.
Context: They just signed up, clicked the verification link, and logged in once. We want them to see value in the next 7 days so they actually use the tool.
Format:

• Email 1: Welcome + quick win (under 200 words)
• Email 2: Use case + simple how-to (under 250 words)
• Email 3: Social proof + invite for demo (under 250 words)
  Style: Simple, direct, no jargon.
  Limits: No heavy sales tone, no fake urgency like ‘offer ends in 2 hours’.”

Landing page copy

❌ Weak:

“Write landing page copy for my AI marketing agency.”

✅ Strong:

“You are a conversion copywriter for a digital marketing agency that uses AI.
Goal: Write landing page copy to get discovery calls booked.
Audience: Indian small and mid-sized business owners who are curious about AI but don’t know where to start. Many have been burned by agencies in the past.
Context: Traffic comes from LinkedIn and Google Ads. People are problem-aware but not solution-aware.
Format:

• Hero section: headline, sub-headline, 1-line proof, call-to-action button text
• Section: ‘Who we help’ (3–4 bullet points)
• Section: ‘Problems we solve’ (point + one-line explanation)
• Section: ‘How it works’ (3–4 steps)
• Section: 3 mini case snippets (even hypothetical but realistic)
• Section: FAQ (5 questions)
  Style: Clear, calm, confident. No hype.
  Limits: Don’t promise impossible results. Don’t use buzzwords like ‘revolutionary’, ‘disruptive’, or ‘unicorn’.”

Content calendar

❌ Weak:

“Create a social media content calendar for my brand.”

✅ Strong:

“You are a social media strategist for a digital marketing agency.
Goal: Create a 30-day content calendar for LinkedIn to attract founders and marketing heads who may later become clients.
Audience: Indian founders and marketing heads in tech, D2C, and education, age 28–45. They are busy and hate fluff content.
Context: We offer performance marketing and AI-powered content services. We want to position ourselves as practical, not just ‘motivational quote’ people.
Format:

• Table with: Day, Post Type (carousel/text/poll/reel idea), Hook, 2–3 bullet point outline, CTA.
  Style: Mix of educational, behind-the-scenes, mini case studies, and sharp opinions.
  Limits: No generic ‘Happy Monday’ or filler posts. Every post must either teach, show proof, or start a useful conversation.”

Some practical marketing use cases.

How to use this with tools you already know

This formula works across all popular AI writing tools:

• ChatGPT / Claude / Gemini – great for long, detailed prompts.
• Jasper / Copy.ai / Writesonic – often template-based but still respond well to clear inputs.

Your steps can be:

1. Write a strong base prompt using the 7 parts.
2. Get first output.
3. Improve with follow-ups:
   • “Give me 3 more hooks but more playful.”
   • “Shorten this headline to under 30 characters.”
   • “Rewrite this in Hinglish but subtle.”
   • “Add a local reference for Indian audience.”
4. Then edit like a human:
   • Inject your brand words
   • Adjust rhythm
   • Check claims

AI is your first draft machine.
You are the creative director.

The bottom line: who can talk to AI will win

Riya still uses AI every day.

• For ad angles
• For subject line variations
• For content calendars
• For landing page drafts

But now she doesn’t complain:

“AI copy is so generic.”

Because her prompts are no longer generic.

She treats AI like what it truly is:

A very fast, very eager junior, waiting for a clear brief.

And that’s your edge too.

If you, as a digital marketer, can:

• Think clearly about who you are talking to
• Decide what the asset must do in the funnel
• Give AI a strong ROLE + GOAL + AUDIENCE + CONTEXT + FORMAT + STYLE + LIMITS

…you will create better campaigns, faster, and with less burnout.

Not because AI is magical.
But because you are finally using it like a pro.

FAQs: How to Write Prompt

What is a prompt in AI writing tools?

A prompt is the instruction you give to an AI tool like ChatGPT, Gemini, Claude or Jasper. It tells the AI what to do, who it is writing for, and how the output should look. A clear prompt works like a good brief for a junior copywriter.

Why is the prompt more important than the AI tool?

The same AI tool can give average or amazing output depending on your prompt. If your prompt is vague, the AI will guess and give generic copy. If your prompt is clear about role, goal, audience, context, format, style and limits, the output becomes much sharper and more on-brand.

How to Write Prompt for digital marketing tasks?

To write a good prompt for digital marketing, include these 7 parts:

• Role – who the AI should act as (e.g., performance marketer)
• Goal – what you want (clicks, leads, signups, etc.)
• Audience – who you are talking to
• Context – channel and funnel stage
• Format – ad, email, landing page, carousel, etc.
• Style – tone and brand voice
• Limits – what to avoid (claims, words, emojis)

This structure works for ads, emails, landing pages and social content.

How to Write Prompt for Facebook or Instagram ads?

For Meta ads, your prompt should clearly state:

• The objective (traffic, leads, sales)
• The audience (age, location, pain points)
• The placement (feeds, stories, reels)
• The format you need (primary text, headline, description)
• The tone (premium, playful, bold, etc.)
• Any limits (no medical claims, no “whitening”, emoji rules)

Example line:

“You are a senior performance marketer writing Meta ads for [target audience]. Goal: cold traffic ad that makes them curious enough to click…”

How to Write Prompt for blog content using AI?

When using AI for blogs, mention:

• Topic and focus keyword
• Target reader (beginner, advanced, marketer, founder, etc.)
• Length (e.g., 1200–1500 words)
• Structure (H2s, H3s, FAQs, conclusion)
• Tone (storytelling, practical, case-study style)
• Extra tasks like meta title, meta description and SEO tags

First line can be:

“You are an SEO content writer for a digital marketing blog…”

How to Write Prompt that keeps brand voice consistent?

To keep brand voice, always describe it in the prompt:

• “Tone: warm and trustworthy”
• “Tone: bold, direct, no fluff”
• “Tone: fun, light, conversational, with subtle humour”

Also add a short line like:

“Write like a human, not like a textbook. Simple English, short sentences.”

If you use the same brand voice block in all prompts, your AI content will feel more consistent.

Can I use the same prompt for ChatGPT, Gemini, Jasper and Claude?

Yes. The 7-part structure (role, goal, audience, context, format, style, limits) works across all popular AI writing tools. You may tweak small details, but the base prompt can stay the same. The important part is your clarity, not the brand of the tool.

How many details should I put in one prompt?

Put enough detail so AI understands the who, what, why and where, but keep it readable. A good rule is: if a human junior can understand your prompt in one go, it’s clear enough. If it feels confusing to you, it will confuse AI too.

Should I accept the first output from AI?

No. Think of the first output as a rough draft. Use follow-up prompts like:

• “Shorten this by 30%.”
• “Give 3 more hook options.”
• “Rewrite in simpler English.”
• “Make it sound more premium / more playful.”

Iteration is part of How to Write Prompt effectively. The magic happens in 2–3 rounds.

Is using AI prompts considered cheating in client work?

Not if you use AI responsibly. You still do the strategy, audience understanding, messaging and editing. AI only speeds up drafting and variation. Be honest with yourself: if the work still carries your thinking, your insight and your quality control, it’s a tool, not a shortcut.
