Here's a hard truth: 90% of people using ChatGPT, Claude, and Gemini are getting mediocre output — not because the AI is bad, but because their prompts are.

The 10 Prompt Sins (With Before & After Fixes)
1Being Criminally Vague
Vague prompts force the AI to guess everything — topic depth, audience, tone, length, format. You get the "average" of all possible answers, which is mediocre by definition.
BAD PROMPT
Write me a blog post
GOOD PROMPT
Act as a content marketing expert. Write a 1200-word blog post about AI marketing automation for B2B SaaS founders. Include 5 actionable strategies with real-world examples. Use a conversational, authoritative tone. Format with H2 headings and bullet points.
The fix: Add WHO it's for, WHAT specifically you need, HOW LONG, and in WHAT FORMAT.
2Skipping the Role Assignment
Without a role, the AI responds as a generic assistant. With a role, it adopts the expertise, vocabulary, and thinking patterns of that specialist. Research shows role assignment alone improves output quality by 20-30%.
BAD PROMPT
Give me advice on pricing my SaaS product
GOOD PROMPT
Act as a SaaS pricing consultant who has helped 50+ startups optimize their pricing strategy. You specialize in PLG (product-led growth) models. Give me advice on pricing my project management SaaS for teams of 5-50 people. Current price: $12/seat/month. We have 200 customers and 40% monthly churn.
The fix: Start every prompt with "Act as a [specific expert with specific experience]."
3Providing Zero Context
Context is the #1 differentiator between generic and useful AI output. Without it, the AI literally cannot tailor its response to your situation.
BAD PROMPT
Write a cold email for my business
GOOD PROMPT
I run a B2B email marketing agency targeting e-commerce brands doing $1-10M in revenue. Our main offer is a done-for-you email flow setup ($2,500 one-time). Our ideal customer is a DTC brand owner who knows email is important but doesn't have time to set it up. Write a cold email that focuses on the revenue they're leaving on the table.
The fix: Include: your industry, target audience, goals, current situation, and any constraints.
4No Format Instructions
Without format instructions, you get a wall of text. With them, you get structured, scannable output that's immediately useful.
BAD PROMPT
Explain how SEO works
GOOD PROMPT
Explain how SEO works for someone launching their first website. Structure your response as:
1. A 2-sentence TL;DR
2. The 5 most important SEO factors (bullet list, one sentence each)
3. A step-by-step action plan for the first 30 days (numbered list)
4. 3 common mistakes to avoid
Keep the total under 500 words.
The fix: Specify: lists vs paragraphs, headings, word count, sections, and any specific structure.
5Never Including Examples
Examples are the most powerful prompt technique. They show the AI EXACTLY what "good" looks like, eliminating guesswork.
BAD PROMPT
Write subject lines for my email campaign
GOOD PROMPT
Write 10 email subject lines for a flash sale on AI prompt templates (normally $29, now $19). Target: entrepreneurs and content creators.
Here are examples of subject lines that have worked well for us:
- "The prompts that made me $14,718 in 3 weeks" (42% open rate)
- "Stop writing bad AI prompts (here's the fix)" (38% open rate)
Match this style: curiosity-driven, specific numbers, conversational.
The fix: Include 1-3 examples of ideal output. If you have performance data, share it.
6Setting No Constraints
Without constraints, AI outputs are often too long, too broad, or off-target. Constraints focus the response and prevent wasted effort.
BAD PROMPT
Create a social media strategy
GOOD PROMPT
Create a 30-day social media strategy for an AI tools company on Twitter/X. Constraints:
- Budget: $0 (organic only)
- Post frequency: 1 tweet per day + 5 replies
- Content types: educational threads, tool demos, memes
- Avoid: generic "AI will change everything" takes
- Include: specific engagement tactics and a content calendar template
The fix: Add word limits, budget, what to avoid, what to include, and any hard requirements.
7Writing a Google Search Instead of a Prompt
AI is not a search engine. It generates answers, it doesn't retrieve them. Treating it like Google gives you surface-level, SEO-optimized fluff.
BAD PROMPT
best marketing tools 2026
GOOD PROMPT
Act as a digital marketing consultant. Recommend the 5 best marketing tools for a bootstrapped SaaS startup in 2026 with a budget under $200/month. For each tool, include: name, monthly cost, primary use case, one specific way to use it to generate leads, and one limitation. Format as a comparison table.
The fix: Transform search queries into structured requests with audience, format, and specificity.
8Being Overly Polite (at the Expense of Clarity)
Politeness filler wastes tokens and adds zero information. The AI doesn't have feelings — it responds to instructions, not manners.
BAD PROMPT
Hi there! I was wondering if you could maybe help me with something? I would really appreciate if you could possibly write something about marketing? Thank you so much in advance!
GOOD PROMPT
Write a 500-word guide on email marketing for e-commerce beginners. Include 3 essential automations to set up on day one. Use a friendly, jargon-free tone.
The fix: Replace courtesy with clarity. Every word should carry information.
9Accepting the First Output
First outputs are drafts, not finals. The AI gets dramatically better with feedback. Most people quit at the first response and miss 80% of the value.
BAD PROMPT
[Uses first response without iterating]
GOOD PROMPT
"Good start, but the tone is too formal. Make it more conversational — like you're explaining this to a friend at a coffee shop. Also, the third point about analytics is too vague. Replace it with a specific example using Google Analytics 4."
The fix: Always do 2-3 rounds of iteration. Be specific about what to change.
10Trying to Do Everything in One Prompt
Asking for everything at once produces shallow output on every topic. Breaking it into steps produces deep, actionable output on each.
BAD PROMPT
Write me a complete marketing plan with social media strategy, email sequences, blog content calendar, ad copy for Facebook and Google, influencer outreach templates, and a PR strategy for my new SaaS product
GOOD PROMPT
Let's build a marketing plan step by step. Start with Step 1:
Act as a social media strategist. Create a 30-day Twitter/X content calendar for a new SaaS product launch. Include: daily post type (thread, poll, meme, case study), topic, and best posting time. Target audience: startup founders aged 25-40.
The fix: Break complex requests into 3-5 focused prompts. Build on each response.
