⚙️ Automate Blog Posts & Banners with Custom GPTs

If you’re using ChatGPT but not GPTs (custom assistants), you’re missing out on automation superpowers. I built a GPT that lets me generate blog posts and CTA banners with a single structured prompt.

📦 What This GPT Does

• Writes full SEO-optimized blog articles
• Generates a thumbnail image description + prompt
• Creates CTA banner with title, description, button text, and link

✍️ Example Prompt I Use

Create a blog post on “Best AI Tools for Bloggers”
– Title (SEO)
– Tags
– 1-sentence summary
– Thumbnail image info (description, alt tag, keywords, MJ prompt)
– Body (English + Korean translation)
– CTA banner linked to https://promptrend.tistory.com/29

💡 Why It Works

Instead of copying and pasting between tools, everything is structured inside the GPT. I can run one prompt, get the full output, and paste it into Tistory in minutes.

🖼️ Banner Generator Bonus

I created a second GPT just for banner design. It asks for:

• Topic
• Message
• Button text
• Design tone (color, style)

Then it outputs full HTML with center alignment, border, and call-to-action tone.

🚀 The Impact

This workflow helped me scale from 3 posts/week to 7 posts/week — all while keeping the layout consistent and professional.
