Turn your blog into a set-and-forget content engine: every new article is instantly repurposed into channel-specific social posts with visuals, keeping your brand visible on LinkedIn, X, and Reddit without extra copywriting time. Perfect for lean marketing teams who want consistent, always-on distribution from a single source of content. How it works • Watches your blog RSS feed (or receives a single URL) and detects new articles. • Saves each post in Postgres so every article is only processed once. • Fetches the article HTML, extracts the main body content and sends it to OpenAI (GPT-4.1). • OpenAI creates platform-optimized copy: 1 LinkedIn post, 1 X/Twitter post, 1 Reddit post + image prompts. • Generates on-brand images with OpenAI and publishes everything automatically to LinkedIn, X, and Reddit. • You can also trigger it manually or via webhook whenever you want to push a specific campaign. Setup Steps • Time: around 20–40 minutes for someone familiar with n8n and the platforms. • Create a Postgres table “rss_items” with fields: guid (PRIMARY KEY), title, link, published_at. • Add credentials in n8n for: – Postgres – OpenAI – LinkedIn OAuth2 – X/Twitter OAuth2 + OAuth1 (for media upload) – Reddit OAuth2 • In the RSS node, set your blog feed URL (for example: https://yourblog.com/feed). • In the webhook node, confirm the URL/path you want external tools or other workflows to call with a “link” field. • Run the manual trigger with one test blog URL to verify: – Article content is extracted correctly. – AI returns LinkedIn/X/Reddit posts and image prompts. – Posts and images appear correctly on all social accounts. • Once tests look good, enable the Schedule Trigger so Blog2Social AI runs automatically at your chosen interval.

Every time you publish a blog post on WordPress, this workflow automatically creates unique, platform-optimised captions for Facebook, Instagram, Twitter and LinkedIn — and publishes them all simultaneously without any manual effort. Built for content creators, digital marketing agencies, SEO agencies, bloggers, and businesses that publish blog content regularly and want to maximise reach across social media without spending hours manually writing different versions for each platform. The Problem This Solves Most businesses publish a blog post and then either copy and paste the same text to every social media platform — which performs poorly because each platform has different audience expectations, character limits, tone and algorithm preferences — or they skip social media promotion entirely because writing four different captions for one post takes too much time. The result is wasted content. Hours of writing a great blog post go unnoticed because the distribution is manual, inconsistent, or nonexistent. This workflow solves that completely. One WordPress publish triggers everything. The AI writes platform-specific captions that actually match how each platform works. Every post gets promoted everywhere automatically. How It Works Step 1 — WordPress Webhook Trigger The workflow starts the instant you publish a post on WordPress. This requires a webhook plugin installed on your WordPress site — the recommended free option is WP Webhooks (available on WordPress.org plugin directory). When you publish or update a post to published status, WP Webhooks sends a POST request to your n8n webhook URL with the full post data including title, content, permalink, thumbnail URL, and post type. No polling. No scheduled checks. The workflow fires in real time the moment your post goes live. Step 2 — Post Type and Status Filter Before any processing happens, the workflow checks two conditions: The post type must be post (not page, product, or custom post type) The post status must be publish (not draft, pending, or scheduled) This ensures the workflow only runs for actual published blog posts and ignores everything else — drafts, page updates, WooCommerce products, and any other WordPress content types. Step 3 — HTML to Markdown Conversion WordPress post content arrives as raw HTML with tags, shortcodes, and formatting markup. Before sending this to an AI model, the workflow converts the HTML content to clean Markdown text using the built-in Markdown node. This removes HTML tags, cleans up formatting, and gives the AI clean, readable text that produces significantly better caption quality than feeding raw HTML. Step 4 — Data Normalization A Set node extracts and organises all the data needed for the rest of the workflow into clean variables: post_title — the blog post title post_content — the cleaned Markdown content post_link — the full permalink URL to the published post post_thumbnail — the featured image URL used for visual posts on Facebook and Instagram facebook_page_id — your Facebook Page ID for the Graph API call instagram_id — your Instagram Business Account ID for the Graph API call Step 5 — AI Caption Generator An AI agent powered by OpenRouter (GPT-4o) reads the post title, link, and the first 800 characters of the post content, then generates four completely different captions — one for each platform — in a single API call. Each caption is written according to strict platform-specific guidelines: Twitter/X caption: Maximum 220 characters. One punchy insight or hook from the post. One to two hashtags only. Ends with the post link. Short, direct, and conversational. Facebook caption: Starts with a bold question or statement. Three to five bullet points of what readers will learn. Ends with the post link. Friendly and conversational tone. Maximum three hashtags. Instagram caption: Opens with a bold hook in the first 125 characters to survive the truncation. Three to five key takeaways as short bullet points. Ends with "Link in bio to read the full guide." Three to five relevant hashtags. Does not include the URL in the body since Instagram does not make links clickable in captions. LinkedIn caption: Professional tone throughout. Hook or surprising statement to open. Three to four short paragraphs covering the problem, what the post covers, the key insight, and a call to action with the link. Two to three professional hashtags. Between 800 and 1200 characters total for maximum LinkedIn algorithmic reach. The output is enforced as strict JSON via a Structured Output Parser — ensuring reliable, parseable data for the downstream publishing nodes every time. Step 6 — Simultaneous Publishing to All Platforms After caption generation, the workflow publishes to all four platforms in parallel: Twitter/X: The Twitter node posts the caption directly using OAuth2 authentication. No additional steps required. Facebook: An HTTP Request node calls the Facebook Graph API /{page_id}/photos endpoint, sending the Facebook caption as the message and the WordPress featured image URL as the photo. This creates a photo post with the caption on your Facebook Page, which performs significantly better than link-only posts in terms of reach and engagement. Instagram: Instagram publishing requires two steps as per the official Meta Graph API requirements. First, an HTTP Request node calls /{instagram_id}/media to create a media container with the caption and featured image URL. Second, another HTTP Request node calls /{instagram_id}/media_publish with the container ID returned from the first step. This is the official two-step publishing flow required by Meta. LinkedIn: The thumbnail image is first downloaded via an HTTP Request node (LinkedIn requires binary image data, not just a URL). Then the LinkedIn node creates a post using the downloaded image binary along with the LinkedIn caption. The post is published to your company organisation page using OAuth2 authentication. WordPress Plugin Required This workflow requires a webhook plugin installed on your WordPress site to send post data to n8n when a post is published. Recommended: WP Webhooks (Free) Available at wordpress.org/plugins/wp-webhooks After installing WP Webhooks on your WordPress site: Go to Settings → WP Webhooks in your WordPress dashboard Click Send Data tab Add a new webhook Select trigger: Post Published or Post Updated Paste your n8n webhook URL as the delivery URL Save and test The plugin will send a POST request to n8n with the full post data every time you publish a blog post. Alternative options: WPBrutha Webhooks Bit Integrations (free plugin with webhook sending) Custom code using WordPress transition_post_status hook if you prefer a code-based approach Payload Structure Your n8n webhook node expects this data structure from WordPress: { "post": { "post_title": "Your Blog Post Title", "post_content": "Your full HTML post content", "post_type": "post", "post_status": "publish" }, "post_permalink": "https://yoursite.com/your-post-slug/", "post_thumbnail": "https://yoursite.com/wp-content/uploads/featured-image.jpg" } The exact field names depend on which WordPress webhook plugin you use. Adjust the Set node field mappings to match the payload structure sent by your chosen plugin.

Schedule and optimize social media posts to Twitter and LinkedIn using AI This workflow automates the entire lifecycle of social media management—from fetching draft content to AI-driven optimization and multi-platform publishing. Who’s it for Social media managers, marketing teams, and content creators who use Google Sheets to plan their content but want to leverage AI for better engagement and automate the repetitive task of cross-platform posting. How it works The workflow is triggered either hourly or manually via a webhook. It fetches scheduled content from a designated Google Sheet and identifies posts ready for publication. An AI Agent (OpenAI) then analyzes the raw content to generate two optimized versions: a punchy, character-limited post for Twitter and a more professional, detailed version for LinkedIn. After generating relevant hashtags and engagement tips, the workflow publishes the posts simultaneously. Finally, it logs the live URLs back to your spreadsheet and sends a performance summary to a Slack channel for easy tracking. How to set up Google Sheet: Create a sheet with columns for status, content, platforms, scheduled_time, hashtags, and tone. Credentials: Connect your Google Sheets, OpenAI, Twitter (X), LinkedIn, and Slack accounts. Node Configuration: Select your specific spreadsheet and worksheet in both the "Fetch Content" and "Update Content" nodes. Slack: Specify the channel name or ID in the Slack node to receive notifications. Activation: Test with the Manual Webhook, then toggle the workflow to "Active." Requirements Google Sheets OAuth2** OpenAI API Key** (using GPT-4o-mini or higher) Twitter (X) OAuth2** LinkedIn OAuth2** Slack Bot Token** How to customize the workflow AI Tone**: Modify the "System Message" in the AI Content Optimizer node to match your brand's unique voice. Additional Platforms**: Extend the branching logic after the AI Parse node to include platforms like Discord, Facebook, or Mastodon. Advanced Scheduling**: Adjust the Filter node's JavaScript code if you use a different date format or status labels in your spreadsheet.
