Marketing Prompts for LLMs

Every marketer has faced a blank page with a deadline approaching. LLMs can help you move past that moment faster. These 20 prompts cover six common marketing tasks, from ad copy to campaign brainstorming, and work with any major AI prompt library you already use.

Each prompt below is ready to copy. Replace the bracketed placeholders with your specific details, paste into ChatGPT, Claude, or Gemini, and review the output. The results will need editing, but the first draft comes in seconds instead of hours.

These prompts work best when you bring context about your brand, audience, and goals. The more specific your inputs, the more usable the output.

Vague prompts produce generic marketing copy that sounds like it could belong to any company. Specific prompts produce drafts that already feel close to your brand voice.

That said, AI-generated marketing copy is not a finished product. Treat every output as a starting point, not a final draft. You still need to fact-check claims and ensure compliance with advertising guidelines.

Layer in the brand nuance that only a human marketer understands.

How to Use These Prompts

Good prompts produce good results, but only if you customize them. Every prompt in this collection contains placeholder text inside [BRACKETS]. Replace each one with real information about your product, audience, or campaign.

You do not need to use these prompts word for word. Think of them as starting structures. The principles behind effective prompt engineering apply here: give the model a clear role, specific context, and a defined output format.

Prompts that include all three elements consistently outperform vague requests.

One common mistake is leaving the brackets too generic. Instead of “[AUDIENCE],” try “millennial homeowners in suburban areas earning $80K-120K.” That specificity produces copy that speaks to real people.

A few practical tips before you start:

• Paste your existing brand guidelines into the prompt for more consistent voice
• Specify the output length you need (e.g., “under 50 words” for social posts)
• Request multiple variations so you can pick the strongest version
• Include examples of what you like to guide the model’s style

Ad Copy Prompts

Writing ads means getting your message across in very few words. These prompts help generate multiple variations quickly, so you can test what resonates with your audience.

Ad copy has strict constraints, character limits, platform requirements, and compliance rules, that make it tedious to draft by hand. LLMs handle the structural requirements well, freeing you to focus on creative direction and messaging strategy.

The best approach is to generate 5-10 variations and select the strongest. Testing multiple angles always beats trying to write one perfect ad.

Google Search Ad Copy

Use this when you need headlines and descriptions that fit Google’s character limits. The prompt includes character count requirements so the model can format output correctly.

Facebook/Instagram Ad Copy

Use this to create scroll-stopping social ad copy with a clear hook. Social ads need to grab attention in the first line because users scroll past most content in under two seconds.

A/B Test Ad Variations

Use this when you have a working ad and want to test new angles. By specifying what each variation tests, the model produces copies that isolate specific variables rather than random rewrites.

Video Ad Script (Short-Form)

Use this for 15-30 second video ad scripts for TikTok, Reels, or YouTube Shorts. Short-form video requires a hook in the first three seconds, or viewers swipe away. This prompt structures the output as a production-ready script with visual directions.

Social Media Prompts

Social media demands volume. You need different formats, tones, and angles across multiple platforms. These prompts help you generate platform-specific content quickly.

The biggest time sink in social media marketing is not writing a single post. It is adapting the same message across three or four platforms, each with different norms.

A LinkedIn post sounds nothing like an Instagram caption. LLMs handle cross-platform adaptation well because you can specify the format, tone, and length constraints directly in the prompt.

Platform-Specific Post Series

Use this to create a week’s worth of content for one platform.

Social Media Repurposing

Use this to turn one piece of content into multiple social posts. Content repurposing is one of the highest-ROI marketing tasks for LLMs because it takes minutes instead of hours.

Engagement-Focused Posts

Use this when you want to start conversations, not just broadcast. Engagement posts require a different structure than promotional ones because the goal is replies, not clicks.

Email Campaign Prompts

Email copy needs to earn attention in a crowded inbox. These prompts focus on subject lines, body copy, and full sequences that drive measurable results.

Most marketing teams using LLMs report that email content is one of the fastest wins. Subject line generation alone can save hours of brainstorming.

Give the model your audience context and campaign goals upfront. This helps it match the right tone and urgency level.

Subject lines make or break email performance. Open rates depend almost entirely on those first 50 characters. Use the subject line prompt below to generate batches you can A/B test rather than agonizing over a single option.

Subject Line Generator

Use this to quickly generate testable subject lines for any email type. Subject lines under 50 characters consistently outperform longer ones, and the preview text acts as a second hook.

Email Drip Sequence

Use this to plan a multi-email nurture campaign. The prompt structures each email around a specific purpose so the sequence tells a coherent story from first touch to conversion.

Cold Outreach Email

Use this for B2B outreach or partnership requests. Cold emails fail when they sound like templates. This prompt forces personalization and brevity, the two factors that determine whether someone reads past the first line.

Landing Page Prompts

Landing pages convert visitors into leads or customers. These prompts help you write pages that follow proven conversion frameworks.

A common problem with landing page copy is that it describes features instead of benefits. The prompts below use specific frameworks like PAS (Problem-Agitation-Solution) to structure the copy around what the reader cares about. If your current landing page has a conversion rate below 2-3%, the copy is often the first place to look.

LLMs handle landing page copy well because the structure is predictable. Hero section, problem, solution, features, social proof, CTA. What varies is the specifics of your product and audience, which is exactly what the [BRACKETS] provide.

Full Landing Page Copy

Use this for a complete page structure following the Problem-Agitation-Solution format.

Headline Testing Variations

Use this to generate multiple headline options for A/B testing. Headlines determine whether someone reads the rest of your page, so testing multiple versions is worth the time.

Feature-to-Benefit Translator

Use this when your landing page lists features but doesn’t explain why they matter. This is one of the most practical prompts in this collection because it takes existing content and transforms it into something more persuasive.

Product Description Prompts

Strong product descriptions answer the buyer’s real question: “What will this do for me?” These prompts help you write descriptions that focus on outcomes, not specifications.

Most product pages list features and specs without translating them into benefits. An LLM can bridge that gap quickly if you provide the technical details and tell it who the buyer is.

The best product descriptions pair a specific feature with a concrete outcome. “2-hour battery life” becomes “enough power to get through your commute.”

Whether you sell on your own site, Amazon, or social media, the format and expectations differ by channel. The prompts below cover single-channel and multi-channel descriptions so you can write once and adapt.

E-Commerce Product Description

Use this for online store product pages. The prompt balances SEO with readability by asking the model to include a keyword without forcing it into every sentence.

Product Description for Multiple Channels

Use this when you need the same product described differently for your website, Amazon, and social. Writing three separate descriptions from scratch takes time. This prompt produces all three in one pass while keeping the core message consistent.

Comparison-Style Product Copy

Use this when buyers are deciding between your product and competitors. Comparison copy works best when it focuses on outcomes rather than features, and when it avoids naming specific competitors directly.

Campaign Brainstorming Prompts

Sometimes you don’t need finished copy. You need ideas. These prompts help you generate campaign concepts, angles, and strategies before you start writing anything.

Brainstorming is where LLMs add the most unexpected value. A single prompt can surface five campaign angles in 30 seconds. You may not use any of them directly, but they often spark a direction you would not have considered on your own.

The trick is to be specific about your constraints: budget, timeline, audience, and goal. Without those guardrails, the model produces ideas that sound creative but are impractical to execute.

Brainstorming prompts work best when you explicitly request at least one low-budget option. This forces the model to think beyond paid media and consider organic, earned, and partnership-driven approaches.

Campaign Concept Generator

Use this at the start of campaign planning to explore creative directions.

Audience Angle Finder

Use this when you know what you’re selling but need fresh angles for different buyer segments. Marketing the same product to three different audiences requires three different messages, and this prompt structures that thinking.

Product Launch Announcement

Use this when you need to announce a new product or feature across multiple channels at once. A strong launch covers the “what,” “why,” and “what to do next” in a format you can adapt for email, social, and internal comms.

Content Calendar Outline

Use this to quickly plan a month of content around a campaign theme. This is especially useful when building AI-assisted content workflows.

Tips for Better Results

These prompts produce usable first drafts, not final copy. Every output needs your editing and brand knowledge applied. Here are ways to improve what the model returns.

Set the right temperature and model settings for creative work. Higher temperature values (0.7-0.9) produce more varied and creative marketing copy.

Lower values work better for data-driven content like product specs. Most models default to a middle temperature, which is fine for a first pass.

Provide real examples from your brand. If you paste a paragraph of your existing copy and tell the model “match this tone,” the results improve noticeably.

LLMs are strong pattern-matchers, so giving them a pattern helps. Even two or three sample sentences make a difference.

Be specific about what you don’t want. Telling the model “no buzzwords, no corporate jargon, no exclamation marks” is often as helpful as describing what you do want. Negative instructions help you write better prompts overall.

Test prompts across different models. ChatGPT tends to produce polished, structured marketing copy. Claude often handles nuance and longer-form content well.

Try the same prompt on two or three models and compare results. What works best varies by task.

Build a swipe file of your best prompts. Save the versions that produce your strongest output, along with notes about what you changed. Small wording changes can shift quality significantly.

If you’re writing email campaigns, use the subject line generator first and test the results before spending time on body copy. Open rates reveal whether your messaging resonates before you invest in the full sequence.

These 20 prompts cover the marketing tasks where LLMs save the most time: generating variations, adapting content across platforms, and brainstorming fresh angles. Start with the category closest to your current workload and customize from there.

For connected SEO-focused prompt workflows, those build naturally on the marketing foundations here. These same prompting principles apply to blog posts, articles, and other long-form content as well.
