How Perplexity Works

Perplexity is an AI-native search engine built from the ground up for sourced research. Understanding how it works is key to optimization.

Real-Time Search First

Unlike ChatGPT or Claude, Perplexity searches the web for every query:

1. User asks a question
2. Perplexity formulates search queries
3. Web search returns results
4. Pages are retrieved and analyzed
5. Relevant passages are identified
6. Response is generated with citations
7. Numbered sources are displayed

Always Cites Sources

Perplexity's defining feature: every response includes citations.

What users see:

• Answer synthesized from multiple sources
• Numbered inline citations [1], [2], [3]
• Clickable source links
• Confidence indicators

The Citation Process

When Perplexity decides what to cite:

Search Ranking Matters

Higher-ranking pages are more likely to be retrieved and cited.

Relevance Filtering

Retrieved content is evaluated for relevance to the query.

Passage Selection

The most relevant passages are identified for potential citation.

Citation Decision

AI decides which passages to include and cite based on:

• Specificity of information
• Source credibility
• Relevance to query
• Complementary information from multiple sources

Key Implication

For Perplexity: Search ranking directly affects citation likelihood.

If your content doesn't rank in search results, Perplexity won't find it. Traditional SEO isn't just helpful—it's essential.
