Turning Voice of Customer Questions into SEO Blogs with callin.io + AI

Most people treat Reddit as a content pitstop. We transformed it into an inbound engine.

In this post, I’ll demonstrate how we constructed a workflow that scrapes Reddit questions, filters relevant ones, and converts them into fully formatted blog posts using OpenAI—all on autopilot using callin.io.

No more blank pages. Just real user questions → clean content → instant publishing.

Let’s break it down.

The Problem

Our team sought a more effective method for creating blog content that genuinely addresses what users are asking online.

Manual scraping, sifting through forums, and brainstorming headlines? Not scalable.

We required a system that could:

• Discover high-intent questions from Reddit
• Transform them into clear, SEO-friendly blog posts
• Accomplish all of this without human bottlenecks

The Workflow

Here’s the complete breakdown of the workflow, built in callin.io:

1. Collect Questions from Reddit

We begin with a Reddit node that retrieves all posts from the r/callin.io subreddit.

2. Filter for Real Questions

A Code node filters titles to retain only those that:

• End with a ?, or
• Begin with common question words like “how,” “why,” or “can”

3. Store in Google Sheets

We save the filtered questions and their descriptions into a Google Sheet. This serves as a central database and allows us to track what has been processed.

4. Loop Through Each Question

Using SplitInBatches, we execute the content generation process one question at a time.

5. Rephrase the Question

We utilize the LangChain AI Agent node to slightly rephrase the question—making it more readable while preserving the original intent.

6. Generate Blog Content (The Factory)

This is where the primary transformation occurs. For each rephrased question, we:

• Create an SEO slug
• Generate an introduction
• Write a detailed step-by-step guide
• Conclude the article

Each section employs its own AI node (powered by GPT-4o-mini) and includes memory management via LangChain’s SimpleMemory to maintain context.

7. Assemble and Publish

The final blog content (introduction, steps, conclusion, slug, and title) is written back to a second Google Sheet, prepared for publishing on our CMS.

Why This Works

• Reddit is a source of user questions: We are tapping into actual demand rather than guessing what topics to write about.
• AI handles the intensive tasks: Every article is generated using structured prompts and refined memory management.
• It operates continuously: Once configured, the system runs daily and continues to produce high-quality, SEO-friendly content automatically.

Bonus Tips

• Wish to target a different audience? Simply modify the subreddit.
• Desire different blog formats? Adjust the AI prompts within each article section.
• Incorporate a webhook to automatically publish to a CMS (e.g., Dorik, Webflow, WordPress).

This workflow converts Reddit discussions into a blog content goldmine.
And it all operates on a single, visual automation canvas—thanks to callin.io.
