How I Automated My SEO Link Building Strategy with n8n and Claude AI

I'm Indiana Aflalo, freelance SEO consultant based in Nice, France. I help small businesses grow their organic visibility through data-driven strategies and automation.
As a freelance SEO consultant, I spend way too much time on repetitive tasks. So I decided to automate my entire backlink strategy using n8n (an open-source workflow automation tool) and Claude AI. Here's how.

The Problem: New Websites Are Invisible

When you launch a new website, you're invisible to Google. The equation is simple:

Zero backlinks = zero trust = zero rankings.

Building backlinks manually is tedious: create accounts, write unique content, publish across platforms, track everything. It takes hours every week for months before seeing any results.

I needed a system that works while I sleep.

The Solution: One Workflow That Does Everything

I built a single automated workflow that runs 3 times per week:

1. Reads a topic from a Google Sheet (my editorial calendar)
2. Generates 4 unique versions of an article using Claude AI via the Anthropic API
3. Publishes automatically to WordPress.com, LinkedIn, Reddit, and Dev.to
4. Updates the Google Sheet with published URLs and status

Total cost: about €3/month for the Claude API. Everything else is free.

The Tech Stack

• n8n — free tier, 2,500 executions/month
• Anthropic Claude API — Sonnet model, ~€0.01 per article generation
• Google Sheets — content database and tracking
• Platform APIs — WordPress REST API, LinkedIn OAuth2, Reddit OAuth2, Dev.to API

The workflow uses a Schedule Trigger node, parallel branches for each platform, and error handling so that if one platform fails, the others still publish.

How the Claude Prompt Works

The key is generating truly unique content for each platform. My prompt instructs Claude to:

• Write a long-form HTML article for WordPress (800+ words, with H2/H3 structure)
• Write a professional short post for LinkedIn (200-300 words, no HTML)
• Write a helpful, non-promotional discussion for Reddit (300-500 words)
• Write a technical markdown article for Dev.to (600+ words, with code examples)

Each version has a different angle, different tone, and different length. Same topic, zero duplicate content. Claude returns everything as a single JSON object that n8n parses and routes to each platform.

The Web 2.0 Cluster Strategy

Here's the part most people miss: isolated backlinks are weak. But when your WordPress blog links to your Dev.to, which links to your LinkedIn, which all link back to your main site — Google sees a coherent content ecosystem, not spam.

Every article I publish includes:

• One link to my main site with varied anchor text
• One cross-link to another platform in the cluster
• Anchor text variation — 80% branded, 10% exact match, 10% partial

This interlinking strategy reinforces every node in the network and passes link equity more effectively than isolated posts.

Results After the First Month

After 4 weeks of automated publishing:

• 15+ backlinks from DA 85+ platforms
• Brand mentions on 10+ platforms
• Google crawling my site more frequently (visible in Search Console)
• First keywords appearing in Search Console impressions
• Zero manual work after initial setup

Not life-changing numbers yet, but for a brand new domain starting from literally zero, this is the foundation everything else builds on.

Why This Matters in 2026: AI Visibility

This is where it gets interesting. With AI-powered search (ChatGPT, Perplexity, Google AI Overviews), the rules have changed:

• Brand mentions matter as much as backlinks for AI citations
• Nofollow links carry nearly the same weight as dofollow for AI visibility
• Sites mentioned on 4+ platforms are 2.8x more likely to be cited by ChatGPT
• Volume of brand searches is the strongest predictor of AI citations

Publishing your brand name alongside your expertise across multiple platforms creates co-occurrence signals that large language models use to build entity associations.

The old game was: get dofollow links to rank on Google.
The new game is: exist everywhere so AI knows who you are.

How to Replicate This

Step 1: Create free accounts

WordPress.com, LinkedIn, Reddit, Dev.to — all free.

Step 2: Set up API credentials

• WordPress: Application Password (Profile > Security)
• Reddit: Script App (reddit.com/prefs/apps)
• Dev.to: API Key (Settings > Extensions)
• LinkedIn: Developer App (linkedin.com/developers)

Step 3: Build the workflow

Schedule Trigger → Google Sheets → Claude API → 4 parallel publication branches → Google Sheets update.

Step 4: Populate your editorial calendar

15-20 topics in Google Sheets with target URLs and keywords.

Step 5: Activate and forget

The workflow runs automatically 3x/week. Check in once a month to add new topics.

What This Won't Do

Let me be honest: this alone won't get you to page 1 of Google. Web 2.0 backlinks are the foundation, not the finish line. For real ranking power, you still need original data studies, guest posts on high-authority sites, and quality content on your main site.
