AI search is the new SERP.
ChatGPT has 800 million weekly users (OpenAI, 2025), and Google’s AI Overviews reach more than 1.5 billion people a month (Alphabet, 2025). When a buyer asks ‘who is the best restoration contractor in Burnaby,’ they get a 3-brand answer set instead of a page of blue links. Being in that answer set is the new top of page 1.
- Brands cited in an AI Overview earned 35 percent more organic clicks than when they were not cited, across 3,119 queries (Seer Interactive, 2025).
- Across 75,000 brands, web mentions correlated 0.664 with appearing in AI Overviews, against 0.218 for backlinks (Ahrefs, 2025). Being talked about now counts for more than being linked.
- The third-party ‘best of’ lists in your trade and your city are what the engines read before they answer. The audit tells you which of them mention you.
- Most owners have never measured where they stand in AI answers. You get the number first, then the 5 moves that lift it.

Citation Checker, the honest grid.
What does the Citation Checker actually do?+
It runs 10 real buying prompts (like 'best water damage restoration in Vancouver' or 'who should I call for a commercial electrical retrofit') through ChatGPT, Claude, and Gemini, then counts how often your domain is cited in the answers. We score citation share (0-100) per platform, identify which competitors are winning the answer set, and prescribe 5 specific moves to lift your score.
Why does AI citation share matter?+
Google says its AI Overviews now reach more than 1.5 billion people a month (Alphabet, 2025), and ChatGPT has 800 million weekly users (OpenAI, 2025). Buyers now put the questions they used to type into Google to these engines. When those engines answer 'who is the best X near me,' being cited puts you in the shortlist the buyer actually calls. Citation share is the new share of voice.
How accurate are the scores?+
Real responses from real production APIs (OpenAI GPT-5 nano with web search, Claude Haiku 4.5 with web search, and Gemini 2.5 Flash with Google Search grounding), all three engines live-web grounded. Scores can vary slightly run-to-run because LLM outputs are stochastic, so run the audit quarterly to track trend, not absolute number.
Is this free? What's the catch?+
Genuinely free. Three runs per day per IP without entering any contact info. After three runs, or to unlock the full per-platform breakdown and the 5 prescriptions, you enter your work email. No credit card, no demo call, no sales follow-up unless you ask for one.
What engines do you query?+
ChatGPT (via OpenAI gpt-5-nano with web_search), Claude (via Anthropic Haiku 4.5 with web_search), and Gemini (via Google Gemini 2.5 Flash with Google Search grounding). Each engine gets the same 10 prompts, so each run is 30 grounded AI calls + a homepage analysis call. Comparable enterprise GEO/AEO audit tools charge $300 to $1,500 per audit; Markingo absorbs the AI API spend on every run so it stays free for you.
How do you pick the 10 prompts?+
We auto-detect your vertical from your domain's homepage, then generate 10 carefully-crafted prompts that mirror how real buyers ask AI engines about that category. 2 awareness-stage, 3 consideration-stage (alternatives to the incumbent), 2 evaluation, and 3 decision-stage (specific job, specific area). You can override the vertical if our auto-detect is wrong.
Will running this audit affect my AI citation share?+
No. Running the audit does not affect how AI engines see you. We are querying their APIs to read responses, not writing to anything. Citation share is determined by what AI engines have already learned from their training data plus what they retrieve via web search at query time. Improving citation share requires changes to the web, see the prescriptions in your report.
What do I do with the report?+
Read the 5 prescriptions, pick the one with the highest impact for the least effort, ship it. The single biggest move for most businesses is to get included in 3 to 5 third-party 'best of' lists in their category and service area. We can run any of the prescriptions for you as part of our SEO and GEO service, or you can hand the report to whoever handles your marketing.
