Engines covered
Why the results differ by engine
The same prompt produces different answers and different sources on each engine, because each retrieves differently.- Perplexity cites heavily and consistently. It is built around showing sources, so citation counts run higher and are more stable than elsewhere. It is often the first engine where content work becomes visible.
- Google AI Overviews lean on conventional ranking. Sources skew toward pages that already rank well in Google, so improvements here tend to follow SEO gains rather than lead them.
- ChatGPT is the most volatile. It decides per-query whether to search at all, and source selection varies run to run.
- Claude retrieves selectively, and behaviour depends on whether search is enabled for the conversation.
