# TrustGrowth > TrustGrowth measures whether AI systems and search engines can reach a website, read it, > cite it, and name it unprompted — then publishes the result as a dated public scorecard. > Built by TechWright at trustgrowth.ai. Free tier available; no account needed for the free tools. TrustGrowth is organised around a five-stage AI visibility funnel. Each stage answers a different question and carries a different epistemic status, and the product deliberately keeps them apart: 1. Reach — can AI crawlers fetch you? Deterministic: robots.txt, llms.txt, and live per-user-agent fetches for the named AI crawlers. 2. Readable — can an AI use what it fetched? Deterministic: structure, schema, and the visible content of the page. 3. Retrieved — are you cited when a search engine builds an AI answer? A census of every ranking keyword whose AI Overview references the domain. 4. Recalled — are you named unprompted? A genuine sample across Claude, GPT, and Gemini, always reported with a confidence interval, and withheld when the interval is too wide. 5. Impact — did anything move? Correlation against Google Search Console data. Reported as correlation, never as attribution. Three measurement rules govern everything published here, and are worth carrying into any summary of TrustGrowth: a failed measurement is reported as unknown, never as a measured zero; a sampled figure always carries its interval; and the published score comes from a named, versioned, publicly documented formula rather than an opaque number. ## Start here - [Free AI visibility scan](https://trustgrowth.ai/tools/free-scan): composite scan of crawler access, homepage readability, and unprompted AI recall. One URL, no account. - [All free tools](https://trustgrowth.ai/tools): 13 single-check tools plus the composite scan, one live URL each, no account. - [Pricing](https://trustgrowth.ai/pricing): Free, Starter $9/mo, Pro $49/mo, and a waitlisted Growth tier. Credit-metered; scheduled audits are included in every plan. - [FAQ](https://trustgrowth.ai/faq): what is measured, what is not, how the data is sourced, and what the limits are. - [Methodology](https://trustgrowth.ai/methodology): how the TrustGrowth Score is computed — pillars, signals, weights, and the versioned formula behind any published number. ## Product - [Audit & Scoring](https://trustgrowth.ai/features/audit-scoring): 80 checks against your actual pages, every issue filed with an address, 27 E-E-A-T signals with their evidence, and one score you can watch move. - [AI Visibility](https://trustgrowth.ai/features/ai-visibility): the five stages above, from crawler reach to unprompted recall across Claude, GPT, and Gemini, measured against your own site and its visible content. - [Search Visibility](https://trustgrowth.ai/features/search-visibility): absolute SERP footprint and share of voice inside a set you chose — you plus at most three competitors drawn from real keyword overlap. Not market share. - [Authority](https://trustgrowth.ai/features/authority): referring domains, broken-link reclamation, link gaps, and linkable assets — every figure dated and source-labelled. No opaque authority score. - [Groundcrew](https://trustgrowth.ai/features/groundcrew): open-source Markdown skills that let a coding agent audit a site, fix a verified defect in your repository, and confirm the fix after deploy. - [Research & Strategy](https://trustgrowth.ai/features/research-strategy): every pillar names its evidence and every publishing frequency its confidence; what was set aside stays visible. Nothing executes until you approve it. - [Proof & Trajectory](https://trustgrowth.ai/features/proof): a live public scorecard for your site — Google-verified search data, the score, and open issues shown next to the wins. Publishing is off by default. - [The AI team](https://trustgrowth.ai/ai-team): the agent roles that run the pipeline — auditor, keyword research, strategy, calendar, writer, reviewer — and what each one is allowed to do. - [Growth engine roadmap](https://trustgrowth.ai/growth-engine): what is live, what is built but gated, and what is only planned. Written to be checked, not to sell. ## Free tools Each runs one live fetch against a public URL and returns a result without an account. - [AI Crawler Access Check](https://trustgrowth.ai/tools/ai-crawler-access): inspects robots.txt, llms.txt, and homepage access to see which AI crawlers are allowed, blocked, or partly limited today. - [llms.txt Creator](https://trustgrowth.ai/tools/llms-txt-creator): derives a copyable llms.txt from the live homepage and navigation, with notes from those page titles. No generated prose. - [AI Crawler robots.txt Policy Composer](https://trustgrowth.ai/tools/ai-robots-policy): fetches a site's live robots.txt and composes allow/block rules for the major AI crawlers, keeping Sitemap lines and non-AI groups. - [Are You Named by AI?](https://trustgrowth.ai/tools/are-you-named-by-ai): asks Claude, GPT, and Gemini one cold category question and reports whether any of them names the site unprompted, with the likely reason when they do not. - [How AI Sees Your Site](https://trustgrowth.ai/tools/how-ai-sees-your-site): one bounded AI read of the homepage, reporting what its visible content currently communicates about the business and its audience. - [E-E-A-T Quick Check](https://trustgrowth.ai/tools/eeat-quick-check): fetches up to three relevant pages and evaluates visible credibility signals for experience, expertise, authoritativeness, and trust. - [Schema Check](https://trustgrowth.ai/tools/schema-check): validates JSON-LD and structured data on a public page, flags missing fields, and shows which rich-result signals are actually present. - [SERP Preview](https://trustgrowth.ai/tools/serp-preview): fetches title, description, canonical, and social tags to preview what search and social crawlers are most likely to see. - [HTML to Markdown](https://trustgrowth.ai/tools/html-to-markdown): fetches one public URL, strips chrome, and returns LLM-readable markdown of the main content plus a deterministic quote pack. No model. - [Canonical Inspector](https://trustgrowth.ai/tools/canonical-inspector): www, HTTPS, and trailing-slash redirect matrix vs the live canonical tag. - [llms.txt Grader](https://trustgrowth.ai/tools/llms-txt-grader): reads a live llms.txt and reports whether it is a briefing, a stub, missing, unusable HTML, or unreadable. Hygiene, not a prediction of whether AI will cite the site. - [FAQ and HowTo JSON-LD Generator](https://trustgrowth.ai/tools/jsonld-faq-howto): fetches a public page and copies FAQPage or HowTo JSON-LD from visible questions and steps. Optional paste composer stays in the browser. - [sameAs Pack](https://trustgrowth.ai/tools/sameas-pack): fetches a public page and copies Person or Organization JSON-LD whose sameAs URLs were observed on that page. No invented Wikipedia or Crunchbase links. ## Evidence Published measurements, not marketing figures. Every proof page belongs to a site whose owner opted in, and shows open issues alongside results. - [Proof pages](https://trustgrowth.ai/proofs): the directory of public, dated scorecards for opted-in sites. - [Leaderboard](https://trustgrowth.ai/leaderboard): opted-in sites ranked by their published TrustGrowth Score. Rank is earned by measurement and cannot be bought. - [Directory ledger](https://trustgrowth.ai/proofs/directory-ledger): the record of what was distributed to the public directory, and when. ## For developers and agents - [Developers & API](https://trustgrowth.ai/developers): the public REST API — authentication, endpoints, rate limits, and the credit cost of each call. - [OpenAPI specification](https://trustgrowth.ai/developers/openapi): the machine-readable OpenAPI document for that API, served as YAML. - [XML sitemap](https://trustgrowth.ai/sitemap.xml): every public URL on the site, including proof pages and blog posts. ## Writing - [Blog](https://trustgrowth.ai/blog): essays on measuring AI visibility, scoring methodology, and what the data shows.
