ChatGPT Search or Perplexity: where to play your visibility
The two AI engines do not cite the same sources or formats. A comparison to prioritize your GEO efforts.
In short:
- Perplexity systematically cites its sources, ChatGPT Search more selectively.
- Both engines overweight Reddit and specialized media.
- The winning strategy covers both with a common content base.
Two engines, two citation logics. Understanding their differences avoids scattering your GEO efforts.
Two answering philosophies
Perplexity is a search engine that writes. ChatGPT Search is a writer that searches. That nuance changes everything for cited sources.
What each one prefers
| Engine | Favorite sources | Winning format |
|---|---|---|
| Perplexity | Media, studies, forums | Lists and data |
| ChatGPT Search | Authority sites, wikis | Direct answers |
Prioritize by sector
In B2B, ChatGPT dominates usage. In product research, Perplexity is rising fast. The llms.txt file is worth working on in both cases.
