Automate Blog Post Social Sharing via RSS: The Friendly Guide for Busy Creators

Automate Blog Post Social Sharing via RSS: The Friendly Guide for Busy Creators

If you’re tired of copying and pasting every new blog post onto social media, it’s time for an upgrade. In this guide, you’ll learn how to automate the whole process, so new articles get shared to Twitter and Facebook without you lifting a finger. This saves you time, gives your content more reach, and helps build a consistent online presence — all thanks to the magic of RSS feeds, a little AI, and a tool called n8n.

Why Automate This?

Manually sharing every blog post is a hassle. It’s easy to forget, or share at the wrong time, or just get burned out. But your blog deserves to be seen! By automating your social sharing, you ensure every new post gets the spotlight. No more forgetting, no more repetitive work. Plus, you can tailor every post to feel personal and engaging, even though it’s automated.

Step-by-Step Setup

1. RSS Feeds – The Content Detector

What’s happening: RSS (Really Simple Syndication) is like a live news ticker for your blog. When you publish a new post, your RSS feed updates automatically. We’ll use this to know instantly when something’s new.

Visual: Picture a river carrying new blog posts downstream — every entry in the flow is a new post ready to be picked up by your automation.

{
  "title": "How to Grow Tomatoes on a Balcony",
  "link": "https://myblog.com/tomatoes-balcony",
  "pubDate": "Thu, 07 Jun 2024 09:00:00 GMT",
  "content": "If you have just a little space...",
  "enclosure": {
    "url": "https://myblog.com/images/tomatoes.jpg"
  }
}

Tips: If your blog doesn’t have an RSS feed, use RSS.app to create one from your site’s URL. You only need the feed URL for the next step.

2. n8n – The Automation Brain

What’s happening: n8n is a drag-and-drop automation tool. You set up a workflow where it checks your RSS feed on a schedule (say, every hour), grabs any new blog posts, then moves them along the pipeline.

Visual: Imagine a conveyor belt: Step 1 is a sensor (RSS), and each blog post detected moves down the belt for processing.

{
  "item": {
    "title": "How to Grow Tomatoes on a Balcony",
    "link": "https://myblog.com/tomatoes-balcony",
    "image": "https://myblog.com/images/tomatoes.jpg"
  }
}

Tips: Start small by setting the automation to check your feed every few hours. You can increase frequency later as you become confident everything works smoothly.

3. OpenAI – Writing Social Captions for You

What’s happening: You don’t want to just spam out “New post: [link]!” AI (like OpenAI, which you can add to n8n) can read your blog post and come up with a catchy, platform-friendly caption, complete with emojis and hashtags.

Visual: Think of this as your clever assistant. It reads your article, then whispers a perfect tweet or Facebook blurb in your ear.

{
  "prompt": "Summarize 'How to Grow Tomatoes on a Balcony' in 240 characters for Twitter, with 2 fun hashtags and an emoji.",
  "caption": "Love gardening in small spaces? Learn how to grow juicy tomatoes on your balcony! 🍅 #UrbanGarden #BalconyHarvest https://myblog.com/tomatoes-balcony"
}

Tips: You can tweak the AI prompt inside n8n to match your style, or add personality (e.g., “Make it playful” or “Add a call to action”). If you have OpenAI API access, it’s easy to plug into n8n’s AI node.

4. Sharing to Twitter (now X) – Going Live

What’s happening: n8n can post directly to Twitter for you. It plugs into the Twitter API (via the Twitter/X node), signs in as you, and publishes the AI-written caption with your link and an image — just like you would.

Visual: Picture a robot with your profile picture, clicking “Tweet” at just the right moment after a new blog post arrives.

{
  "text": "Love gardening in small spaces? Learn how to grow juicy tomatoes on your balcony! 🍅 #UrbanGarden #BalconyHarvest",
  "media": ["https://myblog.com/images/tomatoes.jpg"]
}

Tips: Twitter requires you to have a developer account and set up API keys for n8n to use. It sounds complicated, but n8n guides you through connecting your account. You can also add a delay in your workflow if you want to space out posts (so two blog posts don’t get tweeted at the same second).

5. Sharing to Facebook – Reaching Your Page Fans

What’s happening: Facebook works a little differently, but n8n can still automate posts to your business Pages. You use Facebook’s Graph API (either via a dedicated node or with a simple HTTP Request node in n8n).

Visual: Imagine the same friendly robot, but now it’s posting your update to your Facebook Page, with the right image and a click-worthy message.

{
  "message": "Love gardening in small spaces? Learn how to grow juicy tomatoes on your balcony! 🍅 #UrbanGarden #BalconyHarvest",
  "link": "https://myblog.com/tomatoes-balcony",
  "access_token": "YOUR_PAGE_ACCESS_TOKEN"
}

Tips: Make sure you’re posting to a Facebook Page, not your personal profile — this is what the API supports. You’ll need a Page access token, which you set up in Facebook’s developer settings. Don’t worry, there are plenty of walkthroughs for this, and n8n shows you how. Test with a dummy post if you’re unsure.

Real Example: How a Gardening Blogger Automates Social Sharing

Let’s walk through a day in the life of Sam, a food and gardening blogger. Sam struggles to keep up with posting every new recipe and garden update across Twitter and Facebook. Here’s how their workflow works after setting up automation:

Every morning, n8n checks Sam’s https://samblog.com/rss feed. When Sam publishes a new post, n8n pulls it in, grabs the featured image, and sends the blog’s title and summary to OpenAI. OpenAI returns a snappy, reader-friendly caption. n8n then sends that caption, plus the link and image, out to Sam’s Twitter and Facebook Page automatically — often while Sam is still enjoying coffee.

The best part? Sam tweaks the AI prompts so Twitter posts are concise and witty, while Facebook gets a warmer, friendlier message. The posts go out minutes after publishing new content, every single time, without fail.

This means Sam’s audience always gets the freshest updates, and Sam gets more time to tend to their tomatoes (and spend less time glued to social dashboards).

Tools You’ll Need
