My Favourite System Prompt for Blogging — Set It Once, Use Forever

Stayalive

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!

Since this is a reply/continuity post to an existing forum thread ("My Favourite System Prompt For Blogging: Set It Once, Use Forever"), I'd write it in a conversational style as a fellow forum member rather than an article.

You can post something like this:

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:

Write in a natural human tone.
Avoid robotic or repetitive sentences.
Prioritize helpful and accurate information.
Use proper headings and subheadings.
Add actionable examples whenever possible.
Focus on readability for beginners.
Suggest internal linking opportunities.
Keep SEO in mind without keyword stuffing.

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:

"Include practical insights, personal observations, and realistic examples instead of producing generic text."

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?
