Frequently Asked Questions
Which AI platform is best for SEO?
Perplexity is currently most SEO-friendly because it cites sources inline with visible links, making traffic and conversions trackable. ChatGPT has the largest audience but citations are less visible. Claude excels for authoritative, research-heavy content. Most brands should optimize for all three.
How does each platform cite content differently?
ChatGPT shows sources in a side panel (less visible, fewer clicks). Perplexity cites inline with numbered references (highly visible, drives traffic). Claude provides direct quotes with attribution when search is enabled. These differences significantly impact how you measure and optimize for each.
Can I track ROI from AI citations?
Perplexity offers the clearest tracking—inline citations drive measurable referral traffic. ChatGPT ROI is harder to measure (brand lift, indirect traffic). Claude falls in between. Use UTM parameters, monitor referrer data, and track brand search volume lifts to estimate overall AI-driven impact.
What content works best for each platform?
ChatGPT: structured content with schema markup, E-E-A-T signals, FAQ format. Perplexity: stat-rich explainers, comparison content, quotable facts. Claude: deep technical content, methodology-focused writing, evergreen authority pieces. Match content format to platform strengths.
How do I test my visibility across platforms?
Run the same prompts across all three platforms monthly. Document which cite you, for which queries, with what sentiment. Use tools like Otterly for automated monitoring. Track changes over time as you optimize. Compare your share of voice to competitors.
Should I prioritize ChatGPT because it's biggest?
Not necessarily. ChatGPT's size means more competition and less visible citations. Perplexity's smaller but more engaged audience with clear citation links may drive better ROI. Consider your goals: brand awareness (ChatGPT), measurable traffic (Perplexity), or authority building (Claude).
