AI Writing Best Practices

1. Use AI as an Assistant, Not a Replacement

AI writing tools work best when:

You provide clear direction
You edit and refine outputs
You add your unique perspective
You fact-check information

2. Master Prompt Engineering

Better prompts = Better outputs

Weak prompt: "Write a blog post about project management"

Strong prompt: "Write a 1,200-word blog post for marketing managers about choosing project management software. Include 5 key selection criteria, comparison of 3 popular tools, and decision framework. Use conversational tone with specific examples."

3. Iterate and Refine

Don't accept first output:

Generate initial draft
Identify weak sections
Regenerate or refine
Add your expertise
Finalize with human touch

4. Combine Multiple Tools

Many professionals use:

ChatGPT for drafting
Grammarly for editing
Frase for SEO
Wordtune for refinement

5. Maintain Your Voice

AI can mimic tone, but preserve your unique perspective:

Add personal anecdotes
Include specific examples
Share unique insights
Edit for authenticity

Common Concerns About AI Writing

Will Google Penalize AI Content?

Google's stance: Content quality matters, not how it's created.

Best practices:

Is AI Writing Plagiarism?

AI generates original text, but:

Always fact-check
Use plagiarism checkers
Cite sources when needed
Add original analysis

Can Readers Tell It's AI?

Not edited
Generic content
Repetitive patterns
Lacks personality

Solution: Always edit and personalize AI outputs.
