What the AI Visibility Checker Does
The Onxeera AI Visibility Checker measures your brand’s citation rate across the four major AI search platforms — ChatGPT Search, Google Gemini, Perplexity AI, and Google AI Overviews — for the specific queries your target audience is submitting. It tests each query across each platform, records whether your brand is cited in the AI-generated response, and calculates your overall citation rate as a percentage. The result is a platform-by-platform citation breakdown that shows exactly where your brand has AI search presence and exactly where it has citation gaps — in under 30 seconds, with no technical setup required.
The AI Visibility Checker is the starting point for every GEO program — because without a citation rate baseline, there is no way to measure whether GEO investments are working, no way to prioritize which gaps to close first, and no way to prove ROI to stakeholders who are considering GEO budget allocation. The checker converts the abstract concept of “AI search presence” into a specific, quantified number that can be tracked month over month and compared against competitors.
Why Every Brand Needs an AI Citation Baseline
AI search is now handling over 2 billion queries per day globally — and the brands cited in those AI responses earn brand discovery, awareness, and consideration from every user who reads the AI answer. Brands not cited in AI responses are invisible for that query, for that user, at that moment in their discovery journey. The problem is that most brands have no idea whether they are being cited in AI search — because AI citation data does not appear in Google Analytics, does not show in Google Search Console, and is not tracked by traditional SEO tools. The AI Visibility Checker closes this measurement gap: it gives brands the citation rate data they need to understand their current AI search presence and make informed GEO investment decisions.
Without a baseline citation rate measurement, GEO investment is guesswork — you cannot know which schema implementations, content rewrites, or entity investments produced citation improvements if you do not know where your citation rate started. The AI Visibility Checker establishes the baseline that makes every subsequent GEO investment measurable. Run it before starting any GEO program, then re-run it monthly to track improvement.
How It Works
Step 1: Enter Your Brand and Queries
Enter your brand name and up to 20 target queries — the specific questions your target audience is most likely to submit to AI search engines when researching your category. The queries should cover your most commercially important topics: category recommendation queries (“best [category] for [use case]”), feature-specific queries (“[category] with [specific capability]”), and brand identity queries (“what is [your brand]?”). The query set you test becomes your GEO baseline query set — use the same queries every month to track citation rate improvement over time.
Step 2: The Checker Tests All 4 Platforms
The AI Visibility Checker submits each query to ChatGPT Search, Google Gemini, Perplexity AI, and Google AI Overviews and evaluates whether your brand name, URL, or content is cited in the AI-generated response. Each query-platform combination is tested independently — producing a citation matrix that shows which queries earn citations on which platforms and which combinations produce no citation. The full test across 20 queries and 4 platforms evaluates 80 query-platform combinations and completes in under 30 seconds.
Step 3: Receive Your Citation Rate Report
The checker delivers a citation rate report showing: your overall citation rate (percentage of query-platform combinations where your brand was cited), your citation rate broken down by platform (ChatGPT, Gemini, Perplexity, Google AI Overviews separately), your citation rate broken down by query category, and a list of the specific queries where your brand is not being cited — your citation gaps. The gap list is directly actionable: each uncited query represents a specific content, schema, or entity investment that could earn a new citation and expand your AI search presence.
What You Get in Your Report
Overall Citation Rate
Your overall citation rate — the primary GEO KPI — expressed as a percentage of all tested query-platform combinations where your brand was cited. The overall citation rate gives you a single number that summarizes your AI search presence and can be tracked month over month, compared against competitors, and reported to stakeholders as the primary GEO performance metric. Industry benchmarks from Onxeera’s 2026 GEO Benchmark data: brands with no GEO investment typically show citation rates of 5% to 15%; brands with 3 to 6 months of GEO investment typically show 25% to 45%; brands with 12+ months of GEO investment typically show 50% to 75%.
Platform Breakdown
Your citation rate is broken down by platform — ChatGPT, Gemini, Perplexity, and Google AI Overviews shown separately — so you can identify which platforms are underperforming relative to others. A brand with 60% citation rate on Perplexity but 15% on ChatGPT has a clear platform-specific gap: the ChatGPT gap likely indicates missing external authority signals (ChatGPT weights domain authority more than Perplexity) or GPTBot blocking in robots.txt. Platform breakdown turns a single overall number into a diagnostic that points to specific, actionable investments.
Citation Gap List
The citation gap list shows every query where your brand was not cited on every platform where the gap exists — the direct input to your GEO content and schema prioritization. Each gap in the list is a specific citation opportunity: a query your target audience is submitting to AI search, for which your brand is currently invisible, and for which a targeted GEO investment (comparison content, FAQ section, schema addition) could earn a new citation within 4 to 8 weeks. The gap list is the most practically useful output of the AI Visibility Checker — it converts AI search data into a specific, prioritized action list.
Who Uses the AI Visibility Checker
Marketing Teams Starting a GEO Program
Marketing teams use the AI Visibility Checker to establish the citation rate baseline before starting any GEO investment — ensuring that every subsequent schema implementation, content rewrite, and entity investment can be measured against a documented starting point. Running the checker before and after each GEO investment phase produces the measurement data needed to attribute citation improvements to specific investments — making GEO ROI demonstrable to leadership rather than anecdotal.
Agencies Running GEO Audits for Clients
Agencies use the AI Visibility Checker as the first step in a GEO audit — running it for a client’s brand and primary competitors simultaneously to produce a competitive citation rate comparison that quantifies the GEO gap the agency’s program will close. The checker’s competitive comparison capability (testing multiple brands against the same query set) makes it the fastest tool for producing the before-state data that frames a GEO program proposal. A client’s 8% citation rate vs a competitor’s 47% citation rate, documented in a structured report, is the most compelling GEO investment justification available.
Founders and Solo Marketers Checking AI Visibility
Founders and solo marketers use the AI Visibility Checker to quickly answer the question “is my brand showing up in AI search?” — without needing to manually test queries across four platforms. The 30-second test replaces 20 to 30 minutes of manual testing per query set and produces structured, reportable data rather than informal notes. For brands at the beginning of their AI search journey, the checker provides the first clear picture of where they stand — and the citation gap list gives them a starting point for their first GEO investments even without a dedicated GEO practitioner on the team.
FAQs
Is the AI Visibility Checker really free?
Yes — the AI Visibility Checker is free to use with no account required and no credit card needed. Enter your brand name and target queries and receive your citation rate report immediately. The free tier tests up to 20 queries across all four platforms. Onxeera’s paid plans unlock larger query sets, automated monthly tracking, competitive comparison reports, and historical trend data — but the free checker gives you everything you need to establish a citation baseline and identify your primary citation gaps.
How accurate is the AI Visibility Checker?
The AI Visibility Checker tests queries directly against ChatGPT Search, Gemini, Perplexity, and Google AI Overviews APIs — the same platforms your audience is using. Citation detection accuracy exceeds 95% for direct brand name citations. The checker uses fresh sessions for each query to prevent conversation history from influencing responses. Note that AI platform responses can vary slightly between sessions — the citation rate represents the probability of being cited across multiple query submissions rather than a binary cited/not-cited determination for a single session.
How often should I run the AI Visibility Checker?
Run the AI Visibility Checker monthly using the same query set to track citation rate improvement over time. For brands actively implementing GEO changes (new schema, new content, new entity signals), run the checker 4 to 6 weeks after each major implementation to measure the impact of that specific investment. Onxeera’s paid Citation Tracker automates this monthly measurement — tracking your query set automatically and delivering a citation rate report to your email each month without requiring manual test runs.
What is a good AI citation rate for my brand?
A citation rate above 40% is considered established AI search presence — the brand is consistently cited across the majority of its target queries on at least 2 to 3 platforms. A citation rate between 20% and 40% represents developing presence — meaningful citations in some categories but significant gaps remaining. A citation rate below 20% indicates early-stage or absent AI search presence — the brand is invisible for the majority of queries its target audience is submitting to AI search. Most brands starting a GEO program test at 8% to 15% and reach 35% to 50% within 6 months of consistent GEO investment.
