How I Built an AI-Powered URL Mapping Tool to Save Your SEO Rankings

Ever tried migrating a website without losing your precious SEO juice? It’s about as fun as trying to herd cats while blindfolded.

After years of handling technical SEO and web development projects at Bang Digital, I kept running into the same headache: mapping URLs between old and new sites was a massive time-sink that often led to broken links and lost rankings.

So, I built something to fix it.

Meet Redirect Mapper: Your SEO Migration Wingman

Smart URL Mapper

Redirect Mapper is like having an AI assistant that understands both your old and new site structures. It uses natural language processing (NLP) to intelligently match URLs and suggest redirects, saving hours of manual mapping work.

Here’s the Secret Sauce 🌶️

The tool is built on a stack that prioritizes performance and reliability:

Streamlit for the lightning-fast interface
Docker for consistent deployment
Linode for robust hosting
Cloudflare for edge performance

What Makes It Different?

Smart Pattern Recognition: Unlike basic pattern matching, it actually understands URL context
Confidence Scoring: Each suggested match comes with a confidence score (0.60-0.80 threshold)
Bulk Processing: Handle thousands of URLs in one go
Ready-to-Use Output: Get a CSV file with all your mappings, ready for implementation
