By Damiano Mastrangioli, Co-Founder of Oltre.ai | Published December 2025
Good news: if you've been doing SEO, you're already halfway to ranking on Perplexity.
Unlike ChatGPT, which relies heavily on training data, Perplexity searches the web in real-time and always shows its sources. It operates more like a traditional search engine with AI synthesis layered on top. This means your existing SEO investment transfers directly.
But there's a catch: Perplexity heavily weights freshness. Content under 30 days old gets cited 3.2x more frequently than older posts. Your evergreen content strategy needs an update.
To rank on Perplexity, maintain strong traditional SEO fundamentals, create content that directly answers conversational questions, build domain authority through quality backlinks, and keep content fresh. Perplexity heavily weights recency, with content under 30 days old getting cited 3.2x more frequently. Unlike ChatGPT, Perplexity operates more like a traditional search engine with AI synthesis, making existing SEO investment highly transferable.
What Makes Perplexity Different
Perplexity AI has emerged as a major player in AI-powered search, attracting 153 million monthly visits with 192% year-over-year growth. While not as massive as ChatGPT, Perplexity attracts a particularly valuable audience: researchers, professionals, and users seeking verified, cited answers.
Its tagline captures the approach: "Ask anything. Search, understand, and cite."
How ChatGPT works: Relies heavily on training data, sometimes cites sources, more conversational chatbot, citations optional.
How Perplexity works: Searches the web in real-time, always cites sources, search engine with AI synthesis, citations always visible.
This emphasis on citation means your content can drive traffic even when synthesized into AI responses. Unlike ChatGPT, Perplexity users see exactly where information comes from.
How Perplexity's Algorithm Works
Perplexity's recommendation algorithm has three primary ranking factors:
1. Google Search Rankings
Perplexity heavily draws from sources that rank well in Google. If you're performing well in traditional search, you have a significant advantage.
2. Domain Authority
Perplexity favors authoritative, credible sources. High domain authority signals trustworthiness.
3. Content Relevance and Freshness
Content must directly answer the query, and Perplexity significantly weights recency. Fresh content performs dramatically better.
If you've been doing solid SEO, you're already doing most of what Perplexity requires. Traditional SEO investment is directly transferable.
Why Traditional SEO Matters for Perplexity
Unlike ChatGPT (which relies more heavily on training data), Perplexity actively searches the web in real-time. This makes your traditional SEO investment directly applicable.
Transferable Elements
| SEO Element | Perplexity Impact |
|---|---|
| Keyword optimization | Still matters for query matching |
| Backlinks | Still build authority |
| Technical SEO | Still affects crawlability |

5 Perplexity-Specific Optimization Strategies
While SEO fundamentals transfer, Perplexity has unique characteristics worth optimizing for.
1. Optimize for Conversational Queries
Perplexity users ask full questions, not keywords.

| "B2B SaaS marketing" | "What are the best marketing strategies for B2B SaaS companies in 2025?" |
How to optimize:
- Research question-based queries in your space
- Structure content around conversational questions
- Use question-based headings (H2s and H3s)
- Provide direct answers to likely questions
