Creating prompts for AI models like ChatGPT can be a challenging task. Often, inaccurate, contradictory, or poorly formulated requests lead to unusable results. When you understand why certain formulations don't work, you can strategically avoid these pitfalls and optimize your requests. This guide shows you the most common mistakes when prompting and provides you with valuable tips to receive better, targeted responses.
Key insights The most common mistakes when prompting are:
- Too vague prompts without clear guidelines.
- Contradictory instructions that lead to confusion.
- Lack of context that is necessary for precise answers.
- Insufficient format or style guidelines.
- Negative instructions that are not explicitly formulated.
- Lack of testing, which leads to missed optimization opportunities.
Step-by-Step Guide
1. Avoid Too Vague Prompts
A common mistake when creating prompts is using too vague instructions. For example, a prompt could say: "Write a blog post about marketing." This prompt is not specific enough. Instead, you should provide more precise information, such as the target audience or the style. Formulate concretely, for example: “Write a blog post about marketing for beginners that is 800 to 1000 words long and uses headings.” Remember, the more information you provide, the more precise the result will be.

2. Pay Attention to Consistent Instructions
A second common mistake is contradictory instructions. Phrasings like “Create a short but detailed report” make it impossible for the AI to provide a consistent response. It is important to clearly distinguish between different requirements. For example, you should simply say: “Create a short social media post with a maximum of 50 words” or “Create a detailed report with 500 to 700 words.” Consistency in your instructions is crucial.
3. Context is Everything
The third mistake many people make is the lack of context. An example: "Explain agile methods." Without specifying who this explanation is intended for – for instance, for beginners or advanced users – the result can be unsatisfactory. Always provide clear context, such as: “Explain agile methods for beginners in 5 minutes as a brief overview.” Context is key for precise answers.
4. Define Format and Style
Another widespread mistake is the lack of format or style guidelines. If you just say: “Give me tips for productivity,” the AI does not know in what format the tips should be given. You need to specify the format clearly, like “Give me five bullet points for productivity while working from home” or “Write a flowing text in a casual style.” When you tell the AI how to respond, it leads to better results.
5. Use Negative Guidelines
If you ignore negative guidelines, it can also lead to undesirable results. An example would be: "Write a newsletter about AI without jargon." Clear negative instructions are necessary. Instead, you should specify what should be avoided: “Do not use technical terms or abbreviations and explain all terms in simple language.” This helps the AI understand your expectations.
6. Test Interactively
The last step that many often forget is to test interactively. Simply submit the prompt and do not check the result further. To determine possible ambiguities, you should submit the prompt, review the response, and make adjustments if necessary. Continuously refine your requests in multiple steps to achieve the best results.
Summary – Avoiding Mistakes When Prompting ChatGPT Assistants
In this guide, you have learned about the five most common mistakes when creating prompts and received valuable strategies to avoid these mistakes. Avoid vague instructions, pay attention to consistent and clear guidelines, ensure you provide context, and define format and style. Negative guidelines are just as important as interactive tests of your prompts. With these tips, you will be able to receive high-quality results from AI.
