The Best Claude Prompts for Writing Advertising Copy

If you've ever stared at a blank screen trying to write the perfect ad copy, you know exactly how frustrating it can be. You have the product, you have the idea, but the right words always seem out of reach. This is exactly where Claude can make a difference — and I don't mean in the generic sense where everyone says "AI helps." I mean a concrete, measurable difference that saves you hours of work and produces copy that actually converts.

Claude from Anthropic is particularly well-suited to ad writing for one specific reason: it was trained to follow nuanced instructions and maintain consistent tone. It won't just give you generic text — if you provide the right context, it understands the difference between a Google Search ad and a TikTok video ad, between an audience of 25-year-old fitness enthusiasts and C-suite executives over 50. This sensitivity to context is its superpower.

In this guide you'll find tested, ready-to-use prompts for a range of common advertising scenarios. For each prompt I'll explain why it works, what to expect as output, and how to customize it for your specific case. Whether you're writing Google ads, Meta Ads headlines, or YouTube video scripts, there's something useful here for you.

Ready-to-Use Prompts for Advertising with Claude

1. Google Search Ads (Responsive Format)

You are an expert copywriter specializing in Google Ads. I need to create responsive ads for the following campaign:

Product/Service: [product or service name]
Target audience: [describe your ideal audience]
Key benefits: [list 3-5 key advantages]
Main keyword: [primary keyword]
Desired CTA: [e.g. "Request a quote", "Buy now", "Learn more"]
Tone: [e.g. professional, friendly, urgent]

Generate:
- 15 headlines (max 30 characters each) that include variations with the keyword, emotional and rational benefits
- 4 descriptions (max 90 characters each) that emphasize USP and CTA
- For each text, indicate in parentheses the type of appeal used (logical/emotional/urgency/social proof)

Why it works: This prompt applies the principle of role prompting ("you are an expert copywriter") combined with a structured framework. Giving Claude a specific role significantly improves output quality because it calibrates the register and level of expertise. Requesting exact character limits forces Claude to respect the real technical constraints of Google Ads — a detail many people forget about, but one that makes the difference between a useful prompt and one where you end up reformatting everything.

What to expect: You'll receive a complete set of headlines and descriptions already categorized by appeal type, ready to upload to your Google Ads account. Claude typically produces creative headlines that balance keyword insertion with originality.

Customization tip: Add a section "Competitors to avoid imitating" with two or three names. Claude will understand the tone you want to differentiate from and work in the opposite direction.

2. Headlines and Copy for Meta Ads (Facebook and Instagram)

Act as a senior creative director with 10 years of experience running Facebook and Instagram campaigns.

Brand context: [briefly describe the brand and its values]
Product being promoted: [product name and description]
Specific offer: [e.g. "30% off for 48 hours", "free shipping", "free 14-day trial"]
Target audience: [age, interests, main pain points]
Campaign objective: [awareness / consideration / conversion]
Ad format: [single image / carousel / video]

Create 3 complete ad variations, each with:
1. Hook (first line, max 125 characters) — must stop the scroll
2. Body copy (2-3 lines that develop the message)
3. CTA button text (max 5 words)
4. Creative note: briefly suggest what type of visual would work well with this text

Differentiate the 3 variations by approach: one emotional, one based on data/logic, one using social proof.

Why it works: The prompt uses the technique of specificity layering: each field you fill adds a layer of context that Claude uses to narrow the range of possibilities and produce more targeted copy. The request for three variations with different angles (emotional, logical, social proof) is gold for anyone doing A/B testing — Claude doesn't choose for you; it gives you the options.

What to expect: Three complete ads, structurally different from each other, with creative notes included. The hook is usually the strongest part — Claude excels at generating opening lines that interrupt the scroll because it's seen millions of examples of effective storytelling.

Customization tip: If your brand has a specific voice, add: "Here are three examples of copy the brand has used in the past: [examples]." This kind of few-shot learning in the prompt aligns the output to your brand's style much more precisely.

3. Video Ad Script (15-30 seconds)

You are a copywriter specializing in video advertising for social platforms. Write a script for a [15 / 30] second video ad.

Brand: [brand name]
Product: [product/service]
Problem it solves: [describe the customer's pain point]
Unique solution offered: [what makes the product different]
Target: [audience description]
Platform: [TikTok / Instagram Reels / YouTube pre-roll]
Tone: [humorous / inspirational / educational / urgent]

Required structure:
- 0-3 seconds: Visual hook + first sentence (must create curiosity or immediate identification)
- 4-15 seconds: Problem → Solution (show the benefit in action)
- 16-25 seconds: Proof/credibility (statistic, testimonial, result)
- 26-30 seconds: Clear and specific CTA

For each section, include:
[AUDIO]: spoken text
[VIDEO]: suggested visual description
[ON-SCREEN TEXT]: any captions or overlays

Why it works: Video scripts are among the hardest things to delegate to AI because they require parallel thinking — text, visuals, and audio must work together. This prompt solves the problem with an implicit three-column structure, asking Claude to think simultaneously about all three sensory channels. The second-by-second time breakdown is a real professional technique that "teaches" Claude the correct format.

What to expect: A formatted script ready to share with your video team or creative agency. It won't be perfect on the first pass — video scripts almost always require revision — but it gives you a solid foundation to build on instead of starting from scratch.

Customization tip: Add examples of videos you like: "The tone I'm looking for is similar to this script: [paste text or describe the video]." Claude will use those examples as a stylistic reference.

4. Retargeting Ad Copy

I need to create retargeting ads for people who visited my site without buying.

Product: [product name, price, category]
Common customer objections: [list them, e.g. "too expensive", "not sure about quality", "need to think about it"]
What we offer to overcome these objections: [e.g. money-back guarantee, testimonials, exclusive discount]
Brand tone: [describe in 2-3 adjectives]

For each objection I've listed, write:
1. A headline that indirectly acknowledges the objection
2. A description that resolves it with our specific answer
3. An appropriate CTA

Avoid aggressive tones or ones that make the customer feel "hunted." The goal is to reopen the conversation, not force the sale.

Why it works: Retargeting is a very specific psychological context — you're talking to someone who already knows you but had a hesitation. This prompt uses the technique of objection-based copywriting, which is one of the most effective strategies in advertising. The final note ("avoid aggressive tones") is a negative constraint — telling Claude what *not* to do is often as important as telling it what to do.

What to expect: Copy tailored to each objection, reading like an empathetic response rather than commercial pressure. Particularly useful if you manage e-commerce campaigns with abandoned carts.

Customization tip: Pass Claude real data from frequently asked questions you receive via email or chat. The more realistic the objections you provide, the more precise the copy you'll receive.

5. A/B Test: 5 Headline Variations for the Same Offer

I need 5 very different headlines to test which communication angle works best for this product.

Product: [description]
Offer: [description of offer or promotion]
Target: [audience description]

Create exactly 5 headlines (max 60 characters each), each using a different angle:
1. Headline based on BENEFIT (what the customer gains)
2. Headline based on FEAR or PROBLEM avoided
3. Headline with element of CURIOSITY or intrigue
4. Headline with NUMBER or specific statistic (e.g. "73% of our customers...")
5. Headline with DIRECT QUESTION to the target

For each one, explain in one line the psychological principle it uses and what type of audience it speaks to best.

Why it works: This is one of the most powerful prompts for data-driven marketers. Instead of asking Claude to choose the "best" approach (which is subjective and depends on your specific audience), you deliberately ask for 5 different angles. You're using Claude as a hypothesis generator for testing, not as an oracle. It's a fundamental mindset shift that leads to much better results.

What to expect: Five truly different headlines, not slight variations on the same idea. The explanation of the psychological principle is particularly useful for understanding which audience segment each variation speaks to best.

Customization tip: After receiving the five headlines, ask: "Now create three variations of each headline, keeping the same angle but with different words." You'll get 15 headlines ready for a statistically significant test.

6. LinkedIn Ads Copy (B2B)

You are a copywriter expert in B2B marketing and professional communication on LinkedIn.

Client company: [name and industry]
Service/Product: [description]
ICP (Ideal Customer Profile): [role, industry, company size, main pain points]
Objective: [generate leads / awareness / event registrations / content downloads]
CTA offer: [e.g. "Free demo", "Download the report", "Book a call"]

Write 3 complete LinkedIn ads in Single Image Ad format:
- Intro text (max 150 characters): must resonate with professional pain point
- Headline (max 70 characters): must communicate the business benefit
- Description (max 100 characters): must support the CTA

Tone: professional but not stiff. Avoid unnecessary jargon and phrases like "innovative solutions" or "holistic approach." Talk about concrete, measurable results.

Why it works: LinkedIn copy follows different rules than B2C — your reader is in "work mode" and has zero tolerance for vague promises. The final note explicitly excluding marketing jargon ("innovative solutions", "holistic approach") is a style constraint very effective at getting Claude to produce more direct and credible text.

What to expect: Ads with a professional but readable tone, focused on concrete results. Claude tends to produce excellent intro text for LinkedIn because it knows how to balance authoritative tone with a human approach.

Customization tip: Include one or two brief case studies ("One of our clients in the X industry achieved Y result"). Claude will use this data to produce copy with specific social proof, much more convincing than generic statements.

Prompt Engineering Tips for Advertising with Claude

Now that you've seen the prompts in action, here are the underlying principles that will let you write your own prompts from scratch.

1. Always give Claude a specific role

There's an enormous difference between "write an ad" and "you are a senior copywriter specializing in e-commerce fashion with 8 years of experience running Meta campaigns." The second type of instruction calibrates not only the tone but also the level of sophistication in the copy, the narrative structures Claude uses, and the kind of details it spontaneously includes.

2. Specify technical constraints BEFORE content

For advertising copy, character limits aren't optional — they're the platform's reality. Always insert exact limits at the beginning of the prompt: "max 30 characters for the headline", "max 90 characters for the description." Claude respects these constraints with precision if you specify them clearly. If you add them only at the end, it tends to ignore them.

3. Ask for explanations, not just output

One of the most effective ways to improve Claude's output is asking it not just to generate copy but to explain the reasoning. Ask for psychological principles used, suggest which audience segments each variation is best for, or what makes one headline more effective than another. This kind of thinking-out-loud helps Claude produce better copy in the first place.
