What sources does AI use, and are my contents cited?

AI systems cite sources — but which ones? Source tracking shows which URLs and domains are actually referenced by ChatGPT, Perplexity & Co.

The Problem

AI models like Perplexity openly display their sources. But models without visible citations also rely on specific sources. Marketing professionals who don’t know which of their pages are being cited and which are being ignored can’t optimize their content in a targeted way.

The citation rate is a direct indicator of how relevant your content is from the AI’s perspective.

The Solution: Analyzing Source Tracking

Source tracking shows all cited URLs and their performance:

What the Tracking Shows

  • URL list: Which of your pages are actually being cited?
  • Citation frequency: How often is each URL referenced?
  • Trend: Is the citation rate increasing or decreasing?

    • Strategic Takeaways

  • Frequently cited pages: Your best content — protect and expand it
  • Rarely cited pages: Optimization potential — improve structure and content
  • Uncited pages: May not be AI-readable — technical review needed
  • Trending ↓: Warning — a competitor may have published better content

    • Conclusion

    Source tracking closes the loop between content creation and AI visibility. Anyone who knows which pages are being cited can invest specifically in the right content — and understand why certain pages are preferred.
