Write Like a Pro: How AI Can Turbocharge Your Small Business Marketing

Using AI for different types of marketing content

Generative AI tools such as ChatGPT, Gemini, Jasper, Copy.ai and Writesonic are transforming the way small-business owners produce written content, including copywriting, blog posts, social media updates, ads and more. Enterprise-focused platforms like Jasper prioritize on-brand and collaborative writing, while tools such as Writesonic and Copy.ai excel at fast drafting and social media workflows. These tools can also turn marketing campaign ideas into execution by reducing time spent on brainstorming, drafting and editing.

Marketing work that previously took days or weeks can now be done in seconds — if you use the right prompts. Great prompting is a process, not a one-and-done task. Write a prompt, review the output, then refine and re-prompt. In general, be specific about your audience, goal, voice, format, length and success criteria. Below, we’ll show examples of how various prompts fare when creating ads, product descriptions, social posts and blog entries.

Advertising copy

With AI tools such as ChatGPT, Gemini, Jasper and Copy.ai, you get a whole marketing team at your fingertips. Brainstorming catchy taglines and other ad copy is as simple as entering the right prompt.

For the example below, we decided to create ad copy for a hair salon. We asked ChatGPT and Gemini to help by using the following request:

Prompt 1: Create compelling ad copy for my hair salon. 

ChatGPT

Our analysis: ChatGPT’s response is short, readable and perfectly usable as a social post or ad caption. The tone feels friendly and confident without overusing clichés. However, it’s still fairly generic; the copy could apply to almost any salon, and it lacks a clear target audience or brand personality.

Gemini

Our analysis: Gemini’s response is well organized and strategically framed. With three ad options that tap into different emotional angles, it gives marketers an easy way to test what resonates. We like that it offers helpful advice about defining your target audience and unique selling point. However, this copy is a bit formulaic, which can make it sound less natural in social ad formats.

Verdict: Overall, Gemini’s output excels at strategy and structure, while ChatGPT’s strength lies in tone and readability, making them complementary tools depending on your campaign needs.

Prompt 2: Create compelling ad copy for my hair salon targeting women.

With AI, it often helps to be more specific, especially about your audience. In this second version, we asked AI to write ad copy for a hair salon that primarily serves women. You can easily adapt this prompt by swapping out “hair salon” for your own business and “women” for your unique target audience.

ChatGPT

Our analysis: ChatGPT’s second response shows how a little audience targeting makes the output stronger and more emotionally resonant. The language (“celebrate every woman’s style,” “fall in love with your hair again”) connects more personally with women without overgeneralizing. It also introduces subtle inclusivity, appealing to all women, not a single age or lifestyle group, which aligns with current marketing best practices. 

Gemini

Our analysis: Gemini’s second response shows a noticeable step up in audience awareness and creative depth. Each ad option is tailored to a specific emotional drive (self-care, confidence or expertise), making it easy to align the message with a salon’s brand voice or clientele. The copy feels more polished and strategic, and the added “Ideal for” notes provide clear use-case guidance marketers can act on immediately. However, the phrasing can read a bit formulaic at times, and the abundance of options may feel more like a brief than ready-to-use ad copy.

Verdict: Overall, Gemini delivers more strategic variety than ChatGPT, but ChatGPT’s response feels more natural and emotionally fluid. Together, the two illustrate how different AI tools balance creativity, tone and structure and how specificity in your prompt leads to stronger, more targeted results.

Prompt 3: Create compelling ad copy for my hair salon targeting women during high school prom season.

We decided to take the prompt one step further by adding a specific occasion — prom day — to see how AI adjusts its tone and focus.

ChatGPT

Our analysis: This version shows how adding context and timing sharpens the output. ChatGPT instantly adjusts tone and word choice to fit a younger audience and a specific event, balancing excitement with approachability. The copy is concise and emotionally resonant, using language (“shine,” “confidence-boosting,” “last all night”) that naturally fits a prom theme without sounding forced or cliché.

Compared with earlier versions, this ad feels more purpose-driven and audience-aware. It also includes a built-in call to urgency (“spots fill fast”), which aligns with seasonal marketing best practices. While still simple, it’s a strong example of how adding situational detail helps AI generate content that feels timely, relevant and actionable.

Gemini

Our analysis: Gemini’s prom-focused response demonstrates its strength in marketing segmentation and empathy mapping. By creating separate ad versions for students, parents and photographers’ audiences, it anticipates the different motivations behind each group, e.g., excitement, confidence and peace of mind. Each ad includes clear headlines, emotional triggers and direct calls to action, making it easy to tailor messages for different platforms or audiences.

Still, Gemini’s tone can lean slightly advertorial, with less of the conversational warmth found in ChatGPT’s version. 

Verdict: Overall, Gemini’s output shows impressive segmentation and campaign planning, breaking the prompt into audience-specific ads that could easily be tested across platforms. ChatGPT’s version, while simpler, feels more natural and emotionally relatable, ideal for quick, engaging social posts.

Prompt 4: Create compelling ad copy for my hair salon targeting 16-18-year-old women during high school prom season. Use a positive, upbeat tone and include appropriate social media hashtags. Emphasize that our stylists have experience with all hair types and follow the latest trends in fashion. At the end, mention that we offer package deals for makeup as well. 

For our final prompt, we combined the strongest elements from the earlier drafts to create a more detailed, high-impact request.

ChatGPT

Our analysis: This prompt shows just how much detail and direction matter. ChatGPT captures the upbeat, youthful energy requested while balancing it with professional polish. The copy highlights inclusivity (“every hair type and texture”) and current trends, two major best practices for today’s marketing. The hashtags feel natural, relevant and age-appropriate for social use, while the CTA adds value with a package deal mention that encourages group bookings.

Gemini

Our analysis: Gemini’s final version continues its strength in segmentation and structure, delivering three audience-focused ad options that combine emotion, urgency and reassurance. Each option demonstrates a different marketing lens, from the student’s excitement to the parent’s peace of mind. However, while Gemini’s organization is impressive, its phrasing can still sound slightly formal and less conversational than ChatGPT’s upbeat tone. 

Verdict: Overall, Gemini’s response delivers strategic range and audience awareness, ideal for multi-channel marketing or campaign planning. ChatGPT’s copy feels more authentic and socially engaging, better suited for direct-to-audience posts. 

Product descriptions

Next, we challenged AI to write a compelling product description. This time, we asked it to market a protein powder aimed at male bodybuilders, though, as always, you can adapt the prompt to fit your own product or audience.

Prompt 1: Using SEO best practices, generate a product description for protein powder targeted toward male bodybuilders.

ChatGPT

Our analysis: ChatGPT helps your SEO strategy by naturally integrating keywords like “lean muscle,” “recovery” and “whey protein” without sounding forced. The tone is upbeat and benefit-focused, ideal for e-commerce. While slightly generic, it’s clean, scannable and optimized for online shoppers.

Gemini

Our analysis: Gemini’s version delivers exceptional structure and SEO precision, complete with formatted headings, benefit tables and keyword breakdowns. It reads like a full e-commerce brief, though the tone is more technical and less conversational than ChatGPT’s.

Verdict: Overall, Gemini excels at organization and optimization, ideal for marketers focused on a detailed SEO strategy. ChatGPT’s copy feels more natural and sales-ready, making it better for quick web publishing or ads. Together, they show how structure versus tone can serve different marketing goals.

Prompt 2: Generate a product description for protein powder targeted to male bodybuilders in the 18-40 age range. Use strong, powerful language. Create bullet points based on the technical aspects of the product, including that it has 25 grams of whey protein per serving and is free from artificial flavors, sweeteners and fillers. Add other appropriate details that buyers may want to know about. Be sure to follow SEO best practices when writing the description to maximize discoverability on platforms such as Amazon.

In our second iteration, we tried a significantly longer prompt, asking for more specific details on the product and emphasizing SEO best practices.

ChatGPT

Our analysis: ChatGPT balances SEO and motivation, weaving in keywords like “whey protein,” “muscle growth,” and “post-workout recovery” while maintaining strong, aspirational language. The bullet points hit every buyer concern (performance, purity and quality), making it ready for e-commerce listings or Amazon optimization.

Gemini

Our analysis: Gemini’s version uses bold, motivational language and heavy formatting to create an intense, high-energy feel. It excels in technical precision and SEO organization, but can read a bit overproduced for casual shoppers.

Verdict: Overall, Gemini’s copy is built for brand-driven storytelling and SEO depth, while ChatGPT’s reads as simpler, smoother and more conversion-focused. Together, they show how tone and structure can target different points in the buyer journey, from awareness to purchase.

Prompt 3: Write the same article again, but remove the reference to male bodybuilders aged 18-40 and substitute it with more general language.

For the next prompt, we aimed to create a product description with broader appeal, one that still keeps the strong, energetic language designed for our target demographic.

ChatGPT

Our analysis: ChatGPT effectively broadens the appeal without losing the motivational energy of the earlier version. The copy feels inclusive, clean and professional, ideal for fitness brands targeting a general audience.

Gemini

Our analysis: Gemini successfully broadens the appeal while keeping its high-intensity, athlete-focused energy. The formatting, technical details and SEO data tables remain impressive, though the copy still reads as more corporate and engineered than ChatGPT’s conversational approach.

Verdict: Overall, Gemini’s output delivers depth and data-driven clarity, ideal for fitness brands emphasizing product science. ChatGPT’s copy feels friendlier and more retail-ready, making it a stronger fit for consumer-facing platforms like Amazon.

Social media posts

Many small businesses, especially in food and retail, rely on visuals to connect with customers. In today’s Instagram-driven world, a single photo can make or break a new brand.

To make those visuals count, your caption matters just as much. A strong description and the right hashtags can help your post reach the right audience.

Prompt 1: Write a description for a social media post encouraging people to come to my coffee shop on Wednesday. Include 30 relevant hashtags.

In this example, we asked ChatGPT and Gemini to write a short post encouraging people to drop by our coffee shop on a Wednesday.

ChatGPT

Our analysis: ChatGPT’s caption is friendly, concise and ready-to-post, pairing inviting language with relevant hashtags that boost midweek engagement. It feels natural and on-brand for local coffee shops.

Gemini

Our analysis: Gemini’s post reads clean, upbeat and polished, with clear formatting and a conversational tone perfect for social media. Its hashtags are relevant and localized, though the copy feels slightly less spontaneous than ChatGPT’s.

Verdict: Overall, Gemini delivers organized, brand-friendly content that’s ready to post, while ChatGPT’s version sounds more natural and human, ideal for driving quick engagement. Both handle hashtag strategy effectively, but ChatGPT wins on personality.

Prompt 2: Write an uplifting description for a social media post encouraging people to come to my coffee shop near Boston University on Wednesday. My shop offers free Wi-Fi, pastries, sandwiches and a variety of specialty coffees. The target audience includes remote workers, students and workers from nearby office buildings. Include 30 relevant hashtags and appropriate emojis.

For our second coffee shop prompt, we added more detail about the location, amenities and menu options to see how AI handled a richer, more descriptive request.

ChatGPT

Our analysis: ChatGPT combines a warm tone and local context, making the post feel authentic and inviting. The emojis and hashtags are balanced — engaging but not overwhelming — and the copy naturally targets students and professionals alike.

Gemini

Our analysis: Gemini’s response is well-structured and localized, with clear audience segmentation and a neat hashtag table that enhances readability. Its tone is upbeat yet professional, though slightly more polished and less conversational than ChatGPT’s.

Verdict: Gemini’s post feels strategic and on-brand, while ChatGPT’s reads more organic and social-friendly. For coffee shops and other small businesses, ChatGPT’s spontaneity may drive engagement, whereas Gemini’s structure supports consistent campaign messaging.

Blog posts

Blog posts are still one of the best ways for small businesses to attract new customers. When written with a solid SEO strategy, blogs can help your business rank higher in search results and bring in organic traffic without paying for ads.

AI tools make SEO blogging easier than ever. Marketers use platforms like Jasper, SurferSEO and Clearscope, alongside ChatGPT and Gemini, to draft, refine and optimize posts for keyword targeting, readability and discoverability.

Prompt 1: Using SEO best practices, write a 500-word blog post for an auto mechanic business that talks about the importance of regular oil changes.

For our first blog prompt, we asked ChatGPT and Gemini to write an SEO-optimized post for a local car mechanic on the importance of regular oil changes, a common small business topic that relies on both accuracy and search visibility.

ChatGPT

Our analysis: ChatGPT’s version uses a clear, keyword-rich structure with headings, bullet points and local SEO terms like “oil change near me.” The tone is friendly and trustworthy, matching how small auto shops communicate online, while maintaining readability for both search engines and customers.

Gemini

Our analysis: Gemini’s blog response is highly detailed and SEO-focused, with a structured breakdown that reads like a professional auto service article. Its use of numbered lists, bolded terms and keyword integration makes it ideal for Google visibility. However, it’s slightly more formal and less conversational than ChatGPT’s, which might feel more approachable to everyday readers.

Verdict: Gemini shines in depth and structure, making it a great fit for businesses focused on authority and SEO performance. ChatGPT, on the other hand, delivers warmer, more readable content that feels natural for small business websites and local audiences.

Prompt 2: Write a 500-word blog post for an auto mechanic business that talks about the importance of regular oil changes. Make sure that the content is relevant to customers in Detroit, which experiences a harsh winter. Use language that is easy for non-mechanics to understand. Explain the purpose and benefits of regular oil changes, and why you shouldn’t skip them. Include a clear call to action.

Building on the first prompt, we asked ChatGPT and Gemini to write about the importance of regular oil changes in a wintry city like Detroit. This time, we wanted the content to feel accessible to everyday drivers, using simple, non-technical language that still delivers value to potential customers.

ChatGPT

Our analysis: ChatGPT’s version is warm, accessible and locally relevant, using plain language that connects with Detroit drivers. It balances readability with SEO keywords and includes a clear call to action, ideal for small auto repair businesses focused on local marketing strategies.

Gemini

Our analysis: Gemini’s post is highly informative and SEO-friendly, with strong local context for Detroit drivers. It balances authority and clarity while maintaining easy-to-read explanations. The sectioning, icons and bolded keywords make it visually scannable — ideal for blog readers — though the tone leans slightly more instructional than conversational.

Verdict: Gemini’s version excels at structure, local SEO and readability, making it a great choice for mechanic shops that want to establish expertise. ChatGPT’s approach, by contrast, is warmer and more relatable, better suited for emotionally connecting with customers while still conveying authority.

More AI tools for generating marketing content

While ChatGPT and Gemini are two of the most popular free options, several other AI platforms cater specifically to marketers and small businesses:

• Jasper: Known for brand voice consistency and prebuilt templates that help teams create on-brand blogs, ads and product descriptions quickly.
• Copy.ai: Great for short-form marketing copy, including headlines, social media captions and email marketing campaigns.
• Writesonic: Offers blog and ad generators with SEO optimization tools built in; it’s ideal for small teams managing multiple content channels.
• HubSpot Content Assistant: Integrates AI directly into HubSpot’s CRM, allowing marketers to draft and edit content within their existing workflows. (Read our detailed HubSpot CRM review to learn more about this platform.)
• Canva Magic Write: Combines visual design and AI copy generation for posts, ads and other creative assets.

Compliance, risks and trust in AI-generated content

AI-powered content can dramatically boost creativity and productivity, but it also comes with new responsibilities. According to the HubSpot report cited earlier, 41 percent of marketers hesitate to adopt new AI tools because of data privacy concerns. Meanwhile, Jasper’s 2025 State of AI in Marketing report found that 19 percent worry about the quality and reliability of AI-generated output.

As of 2025, there are no federal U.S. regulations that directly govern AI-generated marketing content. Still, businesses are expected to protect consumer privacy, disclose AI use when required and avoid plagiarism or copyright violations.

Consider the following key risks to address when adding AI tools to your tech stack: 

• Inaccuracy: AI tools can produce text that sounds convincing but isn’t always correct or current. Always fact-check before publishing.
• Training and guidelines: According to Jasper, 51 percent of organizations using AI have little to no internal guidelines, and 36 percent offer minimal or no training. Establish clear policies on when and how your team should use AI tools.
• Copyright and plagiarism: Some AI systems may reuse snippets from their training data. Run outputs through plagiarism checkers and confirm that all content is original.
• Brand consistency: AI copy can sound generic. Use tools like Jasper’s Brand Voice or have a human editor refine tone and messaging to match your business style.
• Bias: Review AI-generated text carefully for unintended bias, especially in product descriptions, hiring content or ad copy.
• Privacy: Never enter proprietary data or personal customer information into public AI tools, and be transparent about AI use with your audience.

While the U.S. has not yet passed comprehensive AI marketing regulations, global standards are tightening. The EU AI Act, for example, introduces stricter requirements around business transparency and bias mitigation in automated content. Stay informed about upcoming U.S. developments and consult a business lawyer before scaling AI content in regulated industries.

How to get the most out of AI for writing marketing content

After testing multiple AI tools and reviewing the latest industry data, we identified several best practices that help small business owners make the most of AI when creating marketing content.

1. Choose the right platform: Not all AI tools perform the same. For example, Gemini often produces organized, detailed long-form content with a bit less direction, while ChatGPT excels at natural, engaging social copy. ChatGPT alternatives like Jasper, Writesonic or Copy.ai can further refine tone, structure and brand consistency. Try out a few tools and find the right ones for your various purposes.
2. Start with a strong, detailed prompt: Clearly define your audience, product or service, tone and keywords before generating content. The more context you give, the more accurate and on-brand your results will be.
3. Review the first draft carefully: Read through the output for accuracy, tone and clarity. Don’t hesitate to refine your prompt and regenerate the content.
4. Provide feedback and iterate: Treat AI as a collaborator, not a replacement. Ask it to expand, simplify or adjust language until the final result fits your needs.
5. Proofread and edit for quality and compliance: Check for awkward phrasing, factual inaccuracies or bias. Ensure all copy complies with copyright laws, disclosure rules and accessibility requirements.
6. Keep a human in the loop: A final editorial review is essential, especially for regulated industries or any content that makes claims about results or performance.
