What is a GEO checker?
A GEO checker evaluates the evidence that influences whether a brand can be discovered, understood, and trusted by generative engines. GEO stands for generative engine optimization: making a website clear, crawlable, and credible enough to be reused in AI answers.
The free Foglift check starts with evidence that can be measured without an expensive live prompt run: open-web brand mentions, authority readiness, content freshness, and technical access. Recurring AI Visibility monitoring then measures the separate outcome: whether tracked answers mention and cite the brand.
AEO (answer engine optimization) and GEO (generative engine optimization) both describe the practice of optimizing content to appear in AI-generated answers.
How the free readiness check works
Foglift combines measured off-site evidence with the Technical Audit. The result stays honest about missing provider data and does not present a readiness score as proof of a live answer-engine mention.
- Open-web mention evidence checks whether independent pages refer to the brand outside its own domain.
- Authority readiness combines measured brand mentions, domain authority, external references, and content freshness.
- Technical readiness checks the page structure and crawler access that help answer engines retrieve and reuse content.
- Unavailable provider evidence stays unavailable instead of being converted into a false zero.
- The free result does not query live AI answers. Recurring monitoring measures mentions, citations, competitors, and share of voice separately.
What recurring monitoring adds
The free result above does not query these engines. A Free account adds weekly Perplexity monitoring; Launch, Growth, and Enterprise add all five supported engines. Each engine has a different citation pattern, so recurring checks show where the brand is mentioned, absent, or supported by a source.
ChatGPT
Whether your brand appears in conversational vendor discovery and category recommendation answers.
Claude
How your brand is described in research-heavy answers where source quality and entity clarity matter.

How your entity, product category, and competitors appear inside Google's broader AI ecosystem.
Google AI Overview
Whether Google can extract your page into AI Overview style answers for high-intent searches.
GEO vs AEO vs SEO
These disciplines overlap, but they answer different operational questions. GEO asks whether AI engines recommend you. AEO asks whether a page can be extracted accurately. SEO asks whether the page can rank and earn clicks in traditional search.
| Dimension | GEO | AEO | SEO |
|---|---|---|---|
| What it measures | Brand visibility in generative engines and AI answer surfaces | How extractable and answer-ready a page is for AI systems | Organic ranking potential in traditional search results |
| Primary signal | Prompt-level mentions, citations, sentiment, and share of voice | Schema, headings, FAQs, entity clarity, and citation-ready formatting | Keywords, crawlability, links, technical health, and content relevance |
| Main use case | Check if AI engines recommend your brand when buyers ask category questions | Improve the page structure AI systems need before they can cite you | Improve rankings and click-through from classic search pages |
| Typical user | Founder, demand generation lead, SEO lead, or agency strategist | Content marketer, technical SEO, developer, or growth operator | SEO team, content team, or site owner |
| Foglift coverage | AI visibility checks across prompts, engines, competitors, and share of voice | Technical Audit with AI Readiness, structured data, FAQ, and crawler checks | SEO, performance, security, and accessibility signals in the free scan |
What your free result shows
Every value comes from the submitted domain and the live Technical Audit. Foglift does not fill missing evidence with sample brands, estimated sentiment, or fabricated prompt results.
- Open-web mentions
- Evidence from independent pages that mention the brand outside its own domain.
- Authority readiness
- A measured view of mentions, external references, domain authority, and freshness.
- Technical readiness
- The access and page-structure prerequisites answer engines need before they can reuse content.
Competitor visibility and share of voice
AI search visibility is competitive by default. If a buyer asks for a category recommendation and your brand is absent, the answer usually names another vendor. Foglift records those competitor mentions so the next action is grounded in the prompt that created the gap.
Share of voice divides your brand mentions by all tracked brand mentions across the same declared prompts, competitors, engines, and measurement window. Answer coverage is a separate metric: the percentage of model-and-prompt checks where your brand appears. Read both together to see whether your brand is present and how much of the observed competitive attention it earns.
For the measurement model behind this metric, read the Foglift guide to AI search share of voice.
GEO checker FAQ
What is a GEO checker?
A GEO checker evaluates the signals that influence whether generative engines can discover and trust a brand. This free check measures open-web mentions, authority readiness, and technical readiness. Recurring monitoring measures live prompt-level visibility separately.
What does generative engine optimization checker mean?
A generative engine optimization checker evaluates how ready a website is for AI-generated answers. It looks at technical access, structured data, entity clarity, open-web mentions, authority, and answer-ready content.
Can I check if ChatGPT recommends my brand?
Recurring Foglift monitoring can check prompt-level mentions and citations. The free result on this page does not query live AI answers; a Free account adds weekly Perplexity monitoring, and paid plans add all five supported engines.
What is a good AI Readiness Score?
An AI Readiness Score above 80 indicates a strong measured foundation across technical and authority signals. It does not guarantee that a brand appears in live AI answers. Scores below 60 usually point to crawlability, authority, or mention-evidence gaps.
How often should I check AI visibility?
High-priority brands should check weekly because AI answers shift as pages are updated, competitors publish, and citation sources change. Teams in active launches or competitive categories often monitor daily.
How is GEO different from AEO?
GEO measures whether your brand appears in AI-generated answers across prompts and engines. AEO measures whether a specific page is structured so AI systems can extract and cite it accurately.
Does Foglift show competitor visibility?
Yes. Foglift records competitor mentions from the same AI responses used to check your brand. That lets you see which competitors win the prompts where your brand is missing.
Is the GEO checker free?
Yes. The Technical Audit and brand mention readiness result are free with no signup. A Free account adds weekly Perplexity monitoring. Paid plans add recurring checks across all five supported engines, competitor visibility, trends, and share of voice.
