How we compare
This comparison evaluates both tools across features, pricing, and AI search optimization capabilities. Our methodology draws on peer-reviewed research into what drives AI engine citations:
- Aggarwal et al., “How Search Engines Integrate AI Overviews,” KDD 2024 — found that structured data and entity clarity improve AI answer extraction rates.
- SE Ranking study of 129,000 domains (2025) — identified referring domains and brand web mentions as the strongest predictors of AI citations.
- Chatoptic correlation study (2025) — demonstrated only a 0.034 correlation between Google rank and ChatGPT citation, confirming AI visibility is an independent channel from traditional SEO.
- Recent AI-citation freshness studies — indicate that AI engines often prefer current, corroborated pages, so we treat recency as one signal rather than a standalone score.
