Examples: Bad vs Good AI Prompts 

Seeing real examples is one of the best ways to understand how good AI prompts work. Bad prompts are usually unclear or too broad, while good prompts give clear instructions, context, and structure.  

Below are a few common examples that show the difference: 

Example 1: Content Writing Prompt 

Bad Prompt: 

  • Write a blog about AI. 

Bad Prompt Output: 

Artificial intelligence is a modern technology that is becoming popular across industries. It helps machines perform tasks that normally require human intelligence. AI is widely used and will continue to grow in the future, impacting businesses and daily life in many ways. 

Why It’s Bad: 

  • No topic focus 
  • No audience or length mentioned 

Good Prompt: 

  • Write a 200–250 words beginner-friendly blog on how AI is used in marketing. Use simple US English and include examples. 

Good Prompt Output: 

  • Artificial intelligence is widely used in marketing to improve customer targeting and engagement. For example, AI can show personalized ads and recommend products based on user behavior. Email campaigns use AI to send messages at the right time, helping marketers save effort and improve results. AI tools also analyze customer feedback to adjust marketing strategies quickly. By using AI, businesses can reach the right audience efficiently and create better customer experiences. 

Example 2: Idea Generation Prompt 

Bad Prompt: 

  • Give me some ideas. 

Bad Prompt Output: 

  • Here are some general ideas you could explore: technology trends, business growth, innovation, education, and future skills. These topics can be adapted for different audiences depending on what you want to write or create content about.

  4. AI Skills in High Demand 
  5. Careers You Can Build After Learning AI 
  6. AI in Everyday Work Life 
  7. AI vs Traditional Careers 
  8. Why Beginners Should Learn AI 
  9. AI Tools for Beginners 
  10. Job Roles in AI

Example 3: Learning or Explanation Prompt 

Bad Prompt: 

  • Explain machine learning. 

Bad Prompt Output: 

  • Machine learning is a branch of artificial intelligence that enables systems to learn from data and improve automatically without being explicitly programmed, using algorithms, models, and statistical techniques. 

Why It’s Bad: 

  • No clarity on depth or audience 

Good Prompt: 

  • Explain machine learning in simple terms for a non-technical beginner. Use short paragraphs and real-life examples. 

Good Prompt Output:

Example 4: Task-Based Prompt 

Bad Prompt: 

  • Summarize this. 

Bad Prompt Output: 

  • This article explains artificial intelligence and discusses its importance and benefits for different industries and professionals. 

Why It’s Bad:
