What is a GEO checker?
A GEO checker measures whether your brand is visible in generative engine answers. GEO stands for generative engine optimization, the practice of making a website clear, crawlable, and credible enough to be cited by AI search engines.
A useful GEO checker looks beyond a single technical score. It should test whether AI systems can access your pages, identify your entity, extract answer-ready facts, and compare your visibility against the competitors that appear in the same responses.
How Foglift checks AI visibility
Foglift keeps Technical Audit evidence separate from monitored AI Visibility. The free control above diagnoses one page. Monitoring then observes prompt-level answers on the engines included in your plan.
- The free control above runs a Technical Audit. It checks one page for SEO, AI Readiness, performance, security, accessibility, and AI crawler access. It does not query live AI answers.
- After setup, an active Free workspace checks tracked prompts in Perplexity weekly. Launch and higher plans add ChatGPT, Claude, Gemini, and Google AI Overview, with monitoring available as often as daily.
- Monitoring parses each successful response for brand mentions, available citations, sentiment, and competitor mentions. Citation availability depends on the engine.
- Answer coverage is brand mentions divided by successful engine and prompt checks. Share of voice divides your mentions by all tracked brand mentions in the same declared prompt set and time window.
- AI Readiness remains a page-scoped Technical Audit score. It does not estimate whether the brand appears in AI answers, and it is never blended with monitored AI Visibility.
Which AI engines can be monitored after setup
Active Free workspaces monitor Perplexity weekly. Launch and higher plans add ChatGPT, Claude, Gemini, and Google AI Overview. The free Technical Audit control above does not query any of these engines.
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.
Perplexity
Which cited sources support or crowd out your brand in answer pages with visible references.
Gemini
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 |
Example Technical Audit result

Separate monitoring example
Available after workspace setup
- Tracked prompt coverage
- 4 of 12 successful checks mention the brand
- Strongest engine
- Claude, 3 of 4 observed mentions
- Top competitor
- pipedrive.com, mentioned in 8 of 12 checks
- Share of voice
- Calculated from tracked brand mentions in this prompt set
Active Free workspaces monitor Perplexity weekly. Launch and higher plans add all five engines, competitor visibility, trends, and share of voice.
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 can combine a Technical Audit with monitored AI answers. The audit checks whether a page is accessible and extractable. Monitoring separately measures brand mentions, available citations, competitors, answer coverage, and share of voice across tracked prompts.
What does generative engine optimization checker mean?
A generative engine optimization checker evaluates how ready a page is for AI-generated answers. The free Technical Audit looks at technical access, structured data, entity clarity, and answer-ready content. Separate monitoring observes live AI visibility signals after setup.
Can I check if ChatGPT recommends my brand?
Yes, through AI Visibility monitoring. Launch and higher plans run tracked prompts across ChatGPT, Claude, Perplexity, Gemini, and Google AI Overview, then report brand and competitor mentions. The free Technical Audit control on this page does not query ChatGPT.
What is a good AI Readiness Score?
AI Readiness is a page-scoped Technical Audit score based on structural signals such as headings, FAQs, entity clarity, citations, and crawler access. A higher score means the page exposes more of those signals. It does not predict whether the brand appears in AI answers.
How often should I check AI visibility?
Active Free workspaces monitor tracked prompts in Perplexity weekly. Launch supports all five engines and monitoring as often as daily, while Growth supports twice-daily monitoring. The Technical Audit can be run separately whenever you need page-level readiness evidence.
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, inside AI Visibility monitoring. Competitor mentions come from the same successful AI responses used to check your brand. They are not part of the free Technical Audit result returned by the control above.
Is the GEO checker free?
The no-signup control on this page returns a free Technical Audit with separate Site Technical Health and AI Readiness evidence. After account setup, active Free workspaces also receive weekly Perplexity monitoring. Launch and higher plans add all five engines, competitor visibility, trends, and share-of-voice tracking.
