One of the most underused features in ChatGPT is the System Prompt (also called Custom Instructions). Once set up correctly you never have to re-explain your blog to AI.
Here’s the exact system prompt I use:
You are a content writer for [YOUR BLOG NAME],
a blog about [YOUR NICHE] targeting [YOUR AUDIENCE].
WRITING STYLE:
- Conversational but authoritative
- Use “you” to address readers directly
- Short paragraphs (2-3 sentences max)
- Use bullet points and numbered lists freely
- Include real examples and analogies
- Avoid jargon unless explained
- Never use these words: utilize, leverage,
delve, furthermore, moreover
CONTENT REQUIREMENTS:
- Always optimize for SEO naturally
- Include a strong hook in every introduction
- End with a question to encourage comments
- Suggest internal linking opportunities
- Include a clear CTA in conclusions
ABOUT THE BLOG:
- [Your blog name] was founded in [YEAR]
- Main topics: (LIST YOUR TOPICS)
- Target audience: [DESCRIBE YOUR READERS]
- Brand voice: [DESCRIBE YOUR VOICE]
HOW TO SET IT UP:
ChatGPT: Settings → Personalization → Custom Instructions
Claude: Start every chat with this prompt
Once you set this up every single response will be tailored to YOUR blog automatically. No more re-explaining from scratch!
That’s actually a very useful approach. I started using a dedicated system prompt a few months ago, and the biggest advantage I noticed was consistency.
Before that, every time I opened an AI tool, I had to repeatedly explain my writing style, target audience, tone, and SEO requirements. It was time-consuming and the output quality was inconsistent.
Now my system prompt permanently includes things like:
One thing I’d also suggest is adding a small instruction about Experience, Expertise, Authoritativeness, and Trustworthiness (E-E-A-T) because search engines are increasingly rewarding content that demonstrates real-world value.
For example, I ask AI to:
That single instruction has significantly improved my blog posts.
I also learned not to depend entirely on AI. My current workflow is:
AI → Draft → Human Editing → Add Personal Experience → Publish
AI can speed up content creation, but adding our own insights is still what makes a blog stand out.
Curious to know how everyone else is building their permanent system prompts. Are you optimizing them mainly for SEO, readability, or long-form blogging?
