# AI Training Data

Definition block AI training data is the large collection of text, images, code, and other content that large language models are trained on to develop their knowledge and language capabilities. Content from authoritative, widely-linked websites before a model's training cutoff is more likely to be represented in that model's knowledge base.

Expanded explanation

## Why AI Training Data Matters for SEO

LLMs 'know' your brand based partly on what was written about it before their training cutoff. Brands with strong media coverage, Wikipedia presence, and authoritative content are better represented. This makes long-term brand-building an indirect but meaningful AI visibility investment.

## How AI Training Data Works

LLMs are trained on massive datasets scraped from the web, Common Crawl, Wikipedia, books, news. Models have a knowledge cutoff, and anything published after that date requires real-time retrieval. Hallucinations often occur when training data is thin or contradictory about a brand or topic.

## Common Mistakes

- Assuming AI knowledge about your brand is accurate, test by asking ChatGPT or Gemini directly
- Neglecting media coverage and Wikipedia presence, these are disproportionately represented in training data
- Not correcting inaccurate AI representations through brand entity optimisation
