SEO Anchor Text Generator with n8n and Claude AI

Generate optimized SEO anchor texts for internal linking using AI automation. This workflow processes your website pages and creates diverse, SEO-compliant anchor variations automatically.

Who's it for

• SEO specialists managing large websites with extensive internal linking needs
• Content managers looking to automate anchor text creation for better search rankings
• Digital marketers seeking to optimize internal linking strategies at scale
• Web agencies handling multiple client websites with SEO requirements

What it does

This workflow automatically generates 10 unique SEO anchor texts with 3-5 linguistic variations each (40-50 total variations per page) using Claude AI. It analyzes your page content, applies advanced SEO criteria, and creates diverse anchor types including exact match, brand anchors, long-tail keywords, contextual phrases, and call-to-action variants.

How it works

The system connects to your Google Sheets document containing page information, filters pages needing anchor generation, processes each page individually through Claude AI, and updates your spreadsheet with generated anchor texts. The workflow ensures semantic relevance, keyword optimization, natural language flow, and linguistic diversity while avoiding over-optimization penalties.
