Why citation share matters

AI search is the new SERP.

ChatGPT alone has 883 million monthly active users. Google AI Overviews hit 1.5 billion users. When buyers ask 'best B2B SaaS marketing platform for Series A startups,' they get a three-brand answer set, not a ten-blue-link SERP. Being in that answer set is the new top-of-page-1.

  • Cited pages get 35 percent more clicks than uncited peers ranked at the same position (Seer Interactive 2026 study).
  • ChatGPT weights authoritative list mentions at 41 percent, Claude at 52 percent, Gemini at 49 percent. If you are not on the 'best X' lists, you are not in the answer.
  • Brand mentions correlate 0.664 with AI Overview visibility, vs 0.218 for backlinks (Ahrefs 75,000-brand study). The weight has shifted.
  • Most B2B SaaS brands score below 25 on their first audit. The fix is concrete, the runway is real, but you have to measure the gap first.

Frequently asked

Citation Checker, the honest grid.

What does the Citation Checker actually do?+

It runs 10 real buyer-intent prompts (like 'best B2B SaaS marketing platforms 2026' or 'alternatives to HubSpot') 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?+

Roughly 1.5 billion people now ask AI engines (ChatGPT, Claude, Google AI Overviews) questions that they used to type into Google. When those engines answer 'best X for B2B SaaS,' getting cited puts you in the consideration set. Not getting cited makes you invisible regardless of where you rank on Google. 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. The catch: every run, anonymized, feeds the Markingo Living Index, our quarterly benchmark report on B2B SaaS AI citation patterns.

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 (devtools, fintech, HR tech, marketing tech, sales tech, or generic B2B SaaS) from your domain's homepage, then generate 10 carefully-crafted prompts that mirror how real B2B founders ask AI engines about that category. Two awareness-stage, three consideration-stage (alternatives to incumbents), two evaluation, and three decision-stage (use-case specific). 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-to-effort ratio for your stage, ship it. The single highest-leverage move for most B2B SaaS brands is to get included in three to five third-party 'best of' listicles in their category. We can run any of the prescriptions for you as part of our SEO and GEO service, or you can hand the report to your existing marketing team.
