AI Content vs. Human Content: What the Data Shows

The study

A study of 31,493 keywords examined how AI-generated versus human-written content performs in both Google Search and AI answer engines including ChatGPT and Perplexity. AI content detection was performed using a validated detector with a 4.2% false positive rate and 0.6% false negative rate.

The findings

Despite AI content being published at record volume surpassing human content output in November 2024 for the first time it performs poorly in both channels. AI content accounts for only 14% of Google Search results and 18% of Answer Engine citations. Human-written content consistently outranks and out-cites AI-generated content across all categories.

The paradox

More AI content is being created than ever. Less of it wins in search or gets cited by AI. The internet is flooding with thin AI-generated pages, and both Google and LLMs are actively deprioritizing it. The implication for your business: high-quality, expert human content is more valuable now than it has ever been. Volume is the wrong strategy.

Key data points:

• AI content volume surpassed human content in November 2024
• AI content accounts for 14% of Google results despite massive volume
• AI content accounts for 18% of LLM citations
• Human content consistently outperforms in both search and AI citation
• Quality and authority signals determine success, not volume
