Frequently Asked Questions (FAQ)

Q: Can Google detect and penalize AI-generated content?
A: Google's stance is that it rewards helpful, high-quality content, regardless of how it's created. The key is not to publish raw AI output. Always fact-check, edit for nuance and brand voice, and add your own unique expertise and insights. The best AI content is human-refined content.

Q: What is the best completely free AI writing tool?
A: For a dedicated platform, Copy.ai's free plan is excellent. For general-purpose writing and brainstorming, the free version of ChatGPT is powerful, though it may have usage limits.

Q: Do I need to learn "prompt engineering" to use these tools?
A: Yes, but it's not as complex as it sounds. The specialized tools (Jasper, Writesonic) have templates and guides to help. The key is to provide clear, specific context about your topic, audience, and goal. The better your prompt, the better the output.
