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 combines a free Technical Audit with AI Visibility monitoring for teams that want prompt-level evidence. The method follows the same ladder used inside the product: technical readiness, authority readiness, brand mentions, review presence, comparison coverage, and share of voice.
- Foglift queries ChatGPT, Claude, Perplexity, Gemini, and Google AI Overview against the prompts that describe your market.
- Each response is parsed for brand mentions, cited domains, answer position, sentiment, and competitor mentions.
- Visibility rate is calculated as brand mentions divided by successful model and prompt checks.
- Share of voice focuses on category and industry prompts, then compares how often you appear against the competitors surfaced in the same answers.
- The visible score rolls technical readiness and AI visibility evidence into a 0 to 100 view so you can separate crawlability issues from market-awareness gaps.
Which AI engines are tested
Each engine has a different citation pattern. Testing all five gives you a practical view of where your brand is known, where it is absent, and which sources shape the answer.
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 brand visibility report
A GEO checker should give you an answer you can act on: where the brand appears, which prompts are missing it, and which competitor is absorbing demand in AI answers.

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 is the percentage of relevant model-and-prompt checks where your brand appears, compared with the competitors surfaced in the same answer set. That makes it more useful than a raw mention count because it shows whether visibility is improving in the searches buyers actually run.
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 tests whether generative engines can find, understand, and recommend your brand. It measures AI visibility across prompts, engines, citations, competitors, and share of voice.
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, answer-ready content, and live AI visibility signals.
Can I check if ChatGPT recommends my brand?
Yes. Foglift can run prompt checks against ChatGPT and other AI engines, then report whether your brand was mentioned, where it appeared, and which competitors were recommended instead.
What is a good AI Readiness Score?
An AI Readiness Score above 80 usually means your site has a strong technical foundation and appears in a healthy share of relevant AI answers. Scores below 60 usually point to crawlability, authority, or prompt-level visibility 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?
The Technical Audit is free and includes AI Readiness signals. Paid monitoring adds recurring prompt checks, competitor visibility, historical trends, and share-of-voice tracking.
