AI Visibility Checker
See if ChatGPT, Perplexity, and Gemini cite your domain — plus llms.txt readiness.
What it calculates
Retrieval readiness (llms.txt, sitemap, robots AI policy) plus live mention rate on 3 category prompts across ChatGPT, Perplexity, and Gemini. Optional competitor share-of-voice on the same sample. Brand and topic are inferred from your homepage when you only enter a domain.
Why it matters
Ranking on Google does not guarantee mentions in AI answers. Operators need retrieval infrastructure, citable content, and trend monitoring. not one-off scores.
The Learn Domains moat
Check → Diagnose → Activate → Ship fixes → Measure lift
Monitoring tools stop at the score. Learn Domains turns gaps into ranked actions inside your command center.

What this measures
AI Visibility Checker estimates AI visibility from inputs you control today. no API keys, no scraped SERPs, no invented benchmarks. Free preview of llms.txt readiness, live brand mentions, competitor sample SOV, and citation URLs. before you guess.
SEO math without operator context is vanity. These formulas connect visibility, authority, and recovery to specific moves you can schedule this week. the same signals Opportunity Engine surfaces inside Learn Domains.
Use the result as a directional signal, not a guarantee. Search engines, ad auctions, and buyer behavior shift. The value is forcing a decision: act, defer, or dig deeper with connected data.
The formula
Learn Domains publishes the math on every tool page so you can audit assumptions:
Preview score blends readiness + sample mention rate (directional). Readiness = weighted checklist. Mention rate = prompts where your brand appears ÷ live probes run.
Adjust inputs to stress-test sensitivity. If a 10% change in one field swings the output more than 40%, that input deserves real data. not a guess. That is when you connect Search Console or Analytics and let the command center replace estimates with measured signals.
What good looks like
Readiness 70+ and mentions on most sample prompts. you are retrievable and cited on category questions.
Good is not "maximum number." Good is trend plus leverage: the metric improves while effort stays bounded. Operators track the delta month over month and tie each point of improvement to a shipped move. refresh, consolidation, new cluster, or pricing change.
When the number is healthy but revenue is flat, trust revenue. Traffic and scores are inputs to money, not substitutes for it.
What weak looks like
Missing llms.txt or zero live mentions. assistants likely skip your brand for category questions.
Weak signals compound quietly. A mediocre score today becomes a missed quarter if you keep publishing without fixing decay, cannibalization, or conversion leaks. The fix is almost never "more content." It is ranked orders against specific URLs.
If you run this calculator and cannot name the next page to touch, stop calculating and start connecting data.
Operator playbook
Run with a niche topic and up to 3 competitors. Fix readiness gaps first, then ship content for missed prompts. Start a trial for weekly AI Visibility Lab tracking and Growth Orders.
Pair every SEO estimate with a single execution order: refresh, consolidate, internal link, or net-new. If the calculator shows opportunity but you cannot name the page to touch, you are not ready to ship. connect data and let Opportunity Engine name the target.
Document assumptions in your runbook: date, inputs, result, decision. Revisit after major algorithm updates, pricing changes, or product launches. Digital assets are systems. snapshots lie; sequences tell the truth.
Worked example
Imagine a founder running a B2B SaaS blog with steady traffic but uneven conversions. They plug conservative inputs into the AI Visibility Checker and get a result that flags opportunity. not crisis.
Instead of rewriting the homepage, they pick one money page, one striking-distance query, and one internal link gap. Two weeks later they rerun the same calculator with updated inputs. The number moved because they shipped. not because they refreshed a dashboard.
That loop. estimate, act, measure. is the Website Command Center workflow Learn Domains automates once your data is connected.
Learn Domains perspective
Most AI visibility tools stop at a score. Learn Domains connects gaps to Mission Brief, Content Operations, Brief Studio reports, Operator skills, and Signal-measured AI referrals.
Calculators are top-of-funnel clarity. The product is daily execution: Mission Brief ranks moves, Opportunity Engine names gaps, AI Growth Analyst answers follow-ups, and Content Operations drafts from opportunity context. always with a human review gate before publish.
Start with a $1 trial if the result exposed a gap you cannot manually prioritize. The command center replaces guesswork with connected signals in your first week.
Common mistakes
Treating a single run as truth. One calculator session is a hypothesis. not a board slide. Run conservative and aggressive scenarios, then validate the sensitive inputs against Search Console, Analytics, or Stripe.
Optimizing the metric instead of the asset. Teams chase a higher score by publishing more URLs while conversion and revenue stall. The metric exists to rank work, not to become the work.
Skipping the "what next" step. If the result does not produce a named URL, a named query, or a named experiment, the session failed. regardless of how impressive the number looks.
Sharing the output without assumptions attached. Stakeholders need inputs and date, not just a headline number. otherwise you will relitigate the same debate next month.
Connecting estimates to your Mission Brief
Free tools and paid intelligence should tell the same story. When you connect Learn Domains, Digital Asset Score, Opportunity Engine, and Traffic Intelligence recompute on live data. the calculator logic becomes a daily signal, not a one-off spreadsheet.
Your first Mission Brief typically surfaces 3–7 orders with reasoning: decay to refresh, striking-distance queries to push, cannibalized pages to consolidate, conversion leaks to fix. The AI Visibility Checker helps you decide whether those orders are urgent before you spend a dollar on ads or freelancers.
That is the category difference: Digital Asset Intelligence ends in action. Charts end in questions. Use this page to qualify the problem; use the command center to ship the fix.
Operators who run this monthly build a sequence: estimate here, validate in Learn Domains, execute from Mission Brief, rerun after ship. That loop compounds. random tool hopping does not.
Examples
SaaS with no llms.txt
Scenario: Domain ranks for product terms but llms.txt is missing.
Outcome: Readiness score tanks; live mentions sparse until corpus is published.
Publisher with strong llms corpus
Scenario: llms-full.txt links pillars; Perplexity mentions brand on 2/3 probes.
Outcome: Readiness passes; remaining gap is prompt-specific content.
Competitive category prompt
Scenario: Three competitors added; sample SOV shows rival at 67% vs your 33%.
Outcome: Clear counter-position order. comparison page or third-party proof.
Use cases
