# Fireflyo > Fireflyo is a generative engine optimization (GEO) platform. It monitors how AI answer engines — ChatGPT, Perplexity, Gemini, Claude, Copilot and Google AI Overviews — represent brands in synthesized answers, ships the structural fixes that improve inclusion (schema/JSON-LD, answer-first structure, comparison tables, llms.txt, crawlability), and proves impact with controlled before/after measurement: patched page cohorts versus matched controls. The first report for any domain is free, self-serve, and delivered in minutes. Key facts: - Category: generative engine optimization (GEO), also called AEO, LLMO or AI visibility. - Primary metric: share of answer — the percentage of relevant buyer prompts in which a brand appears in the engine's answer. - Differentiator: measurement-backed action. Every fix ships with a control group so citation gains are attributable, not correlational. - Positioning: an agent-native GEO service plus platform — AI agents scan engines, draft fixes and queue them for human approval; the platform ships them and proves impact. The action-and-proof layer above commoditized monitoring tools. - CTA: free GEO report at https://fireflyo.com/#report — no credit card, no sales call. ## Pages - [Home](https://fireflyo.com/): what Fireflyo does — see, fix and prove AI answer visibility. - [Blog](https://fireflyo.com/blog/): field notes on GEO, written answer-first. ## Blog posts - [What is generative engine optimization (GEO)?](https://fireflyo.com/blog/what-is-generative-engine-optimization/): definition, scope, GEO vs SEO. - [How AI engines choose which brands to recommend: the four filters](https://fireflyo.com/blog/how-ai-engines-choose-brands/): retrieval, parsing, synthesis, citation — and the lever for each. - [Share of answer: the KPI that replaces rankings](https://fireflyo.com/blog/share-of-answer-metric/): defining and trusting the successor metric to rank position. ## Contact - Email: hello@fireflyo.com
