Writing Better Sales Copy with ChatGPT

One of the more obvious places to get help from ChatGPT is creating sales and marketing content. Whether that’s coming up with advertising copy, social media post ideas, or webinar agendas, we can never have enough marketing content. However, the prompts usually miss the mark because they don’t take sales psychology into account.

In this note, I’ll show you how to generate sales/marketing copy with more purpose and exactness related to proven psychology tactics.

First, though, one trick I just learned is that you can control the variance and creativity in ChatGPT’s output. It’s called Temperature.

A high temperature of 1.0 or above will make ChatGPT more creative.
A low temperature of 0.1 or lower will make ChatGPT more conservative.

Simply add the sentence “Use a temperature of [desired #]” to change ChatGPT’s output.

ChatGPT Prompt 1 – Sales Psychology

Prompt: What are 5 different psychological principles used in effective sales copy?


Effective sales copy leverages various psychological principles to persuade and influence potential customers. Here are five key principles often used:

1. Reciprocity: This principle states that people are more likely to respond favorably to those who have done something for them. In sales copy, offering something of value for free, such as a trial, a gift, or valuable information, can create a sense of obligation that motivates customers to make a purchase.

2. Social Proof: People tend to follow the actions of others, particularly when they are uncertain about the best course of action. Sales copy that includes testimonials, reviews, or endorsements from satisfied customers, influencers, or experts can provide social proof, encouraging potential customers to make a purchase.

3. Scarcity: When people perceive that a product or service is limited in availability, they are more likely to feel a sense of urgency to act. Sales copy that highlights limited time offers, limited stock, or exclusive deals can tap into this principle to drive sales.

4. Authority: People tend to be more persuaded by those who are perceived as experts or authority figures. Incorporating elements that establish the expertise and credibility of the brand or product, such as endorsements from experts, certifications, or awards, can help convince potential customers of the value of the product or service.

5. Consistency and Commitment: People prefer to act consistently with their past actions or beliefs. By getting potential customers to make small commitments, such as signing up for a newsletter or following a brand on social media, sales copy can make them more likely to follow through with a purchase later on. This can be achieved through calls-to-action and engaging content that aligns with the customer's values or interests.

ChatGPT Prompt 2 – Create Sales Copy

With the various psychological tactics top-of-mind, you can now be more directed in what type of sales copy you’re looking for ChatGPT to generate.

Prompt Formula:

As a world-class marketer, write a compelling sales copy in [# of words] or less that speaks directly to [target customer] and encourages them to [desired action]. Use the sales psychology principle of [insert sales principle from above]. Use a temperature of 10.0

[Provide sufficient context and backstory to your product, brand, service, etc. The more detailed, the more that ChatGPT has to work with.]

Prompt Example for Everydays.WTF:

As a world-class marketer, write a compelling sales copy in 280 characters or less that speaks directly to decision-makers and encourages them to become a member of Everydays.WTF. Use the sales psychology principle of Reciprocity. Use a temperature of 10.0

For your reference, Everydays.WTF is QuHarrison Terry’s open-sourced journal that explores the future of technology and unearths consumer behavioral shifts years before they become mainstream.

Prompt Example Output:

"Gain an edge over competitors with a free exclusive report from Everydays.WTF, unveiling tech trends & consumer insights. Unlock your advantage now, and as a thank-you, enjoy a full membership trial. Stay ahead - join the visionary circle today! 🔮📈🚀 #FutureTech #EverydaysWTF"

So that you can witness the variance in ChatGPT’s output, here are the results from the four other sales psychology principles outlined earlier:

[Social Proof] "Join the ranks of savvy decision-makers who rely on Everydays.WTF for groundbreaking tech insights. See what top industry leaders are raving about and leverage exclusive knowledge to lead your business. Stay informed, stay ahead. Act now! 🌟🚀💡 #TechInsights #EverydaysWTF"

[Scarcity] "Last chance! Limited spots left for Everydays.WTF membership. Seize the opportunity to access unparalleled tech insights before it's too late. Elevate your decision-making skills and outpace the competition. Act now - time is running out! ⏳🚀🔥 #TechTrends #EverydaysWTF"

Take the first step - join our community and consistently access groundbreaking tech trends. Be the visionary leader you aspire to be. 🚀💼🔑 #TechLeadership #EverydaysWTF"

Seeing how the language changes based on the sales principle is fascinating. This could be improved by providing more context about who I am and examples of what Everydays.WTF covers.

Additionally, I’d focus on just one psychological principle at a time and give it more directed fodder that fits that principle. Lastly, I’d have it focus on creating three variations in length: 10 words, 100 words, and 1,000 words.
