AI SEO Glossary

An AI Citation is when an AI-powered search engine or answer engine references your website, content, or brand as a source within a generated response. In tools like Perplexity and ChatGPT Search, citations appear as numbered links alongside or below the generated answer. In Google AI Overviews, they appear as source cards. Being cited does not always mean the user will click through, but it establishes your brand as a credible source in the AI’s output, which compounds over time as the same content continues to be retrieved and cited across many queries.

Getting cited in ChatGPT or Perplexity requires your content to be discoverable by their crawlers, relevant to the query being answered, and of high enough quality that the AI’s retrieval system selects it over competing sources. Practical steps include ensuring GPTBot and PerplexityBot are allowed in your robots.txt, creating content that directly and specifically answers the questions your audience asks in these tools, building domain authority through external citations and backlinks, and maintaining content freshness. Perplexity’s citation behavior is heavily influenced by traditional web authority signals, making strong SEO fundamentals directly relevant.

Why it matters: AI citations are the new backlinks. They signal authority to both the AI system and the user reading the response.
