What's the Difference Between SEO, AEO & GEO?
Search has expanded well beyond the classic 10 blue links. However, ranking well in traditional SEO terms no longer guarantees AI visibility. Each layer below needs its own signals, and we check for all three.
- SEO: Search Engine Optimization
- Optimizing a page so traditional search engines like Google can crawl, index, and rank it for relevant queries.
- AEO: Answer Engine Optimization
- Structuring content so AI assistants such as ChatGPT, Claude, and Perplexity can extract and cite accurate answers directly from it.
- GEO: Generative Engine Optimization
- Making content likely to be surfaced and trusted by AI-generated search summaries, such as Google AI Overviews.
| Focus | What we check | Where to run it |
|---|---|---|
| SEO | Meta tags, headings, schema, page speed, backlinks | Website Reviewer |
| AEO | Q&A structure, AI-crawler access, citation signals | Complete SEO, AEO & GEO Audit |
| GEO | Authority signals, semantic HTML, content freshness | Complete SEO, AEO & GEO Audit |
Our own testing shows this matters in practice: when we ran the audit tool against this very homepage and fixed what it flagged, our measured AEO score rose from 55 to 91 and our GEO score rose from 38 to 71 — the same structural changes (real headings for Q&A content, a definition list, a comparison table, and cited sources) are what the audit checks for.
How to get started:
- Run the Complete SEO, AEO & GEO Audit on your homepage.
- Fix the Quick Wins listed at the top of your report first.
- Re-scan periodically to track score changes as AI search keeps evolving.
Why doesn't ranking well in Google guarantee AI visibility?
AI Overviews and standalone assistants increasingly answer queries directly, often without a click-through to any website. Structured, well-cited, and clearly-organized content is more likely to be extracted and quoted. See Google Search Central documentation and Schema.org for how structured data helps both traditional and AI-driven search understand a page.
