# ChurnZero: 25 point Door Gap
- Site: churnzero.com
- Scanned: 2026-09-08
- Scan type: Basic scan
- Business type: content
- Report: https://www.seconddoor.io/r/churnzero-9vg9dn
- Scanner version: 13
AI crawlers are blocked at the network edge despite robots.txt permission, preventing agents from reading the content the site publishes.
## Scores
| Measure | Score |
| --- | --- |
| Humans | 70/100 |
| Agents | 45/100 |
| Composite | 58/100 |
| Door Gap | 25 points |
The human score is the mean of the four human dimensions, the agent score the mean of the six agent dimensions, and the Door Gap the difference between them.
## What the machine actually did
The agent got through 5 of 13 requests, but could not ask whether the door opens for requests carrying the AI crawlers' names. It came up empty on 7 other checks too. That is enough missing for a machine to give up before it reaches a purchase.
- ok      reach the site at all
- ok      find out whether machines are welcome
- missing ask whether the door opens for requests carrying the AI crawlers' names
- missing read the site's own guide for language models
- ok      find out what pages exist
- missing find a contact route for machines
- missing find a published agent interface
- missing find an agent plugin manifest
- missing find out whether verified agents are recognised
- ok      read the homepage as data rather than as a page
- missing find a machine readable API spec
- missing read the developer documentation
- ok      walk the way a visitor would, to a signup form or a product
## Top issues
1. **No security contact information is published, leaving agents and security researchers unable to report vulnerabilities.** (machine_fetchable_trust)
2. **Network edge blocks five AI crawlers that robots.txt explicitly welcomes, preventing agents from reading published content.** (machine_discoverability)
3. **No machine-readable interface exists for agents to understand the site structure, capabilities or how to interact with it.** (agent_aware_instrumentation)
The evidence and the recommended fix for each are on the report page: https://www.seconddoor.io/r/churnzero-9vg9dn
## Files generated from this scan
- **Let verified assistants through** at `notes`, 1 hour, developer. Verify: The next scan opens the homepage and the key pages in a real browser and under the search crawler names, and every one is served.
- **Machine interfaces: where you stand** at `notes`, 10 minutes, no developer needed. Verify: The next scan finds the interface you published answering at its well-known path, and that check passes.
- **security.txt** at `/.well-known/security.txt`, 10 minutes, no developer needed. Verify: The next scan fetches /.well-known/security.txt as text and the security.txt check passes.
- **llms.txt** at `/llms.txt`, 15 minutes, no developer needed. Verify: The next scan fetches /llms.txt as text and the llms.txt check passes.
Each file is written from what this scan found on the site. The content is in the JSON once the evidence is opened: https://www.seconddoor.io/api/reports/churnzero-9vg9dn
## The agent door
- **machine_discoverability** 75/100. Robots.txt names 1 AI crawler explicitly and allows 14 AI agents including GPT, Claude, Perplexity and Google Extended. A sitemap index declares 416 URLs.
- **programmatic_onboarding** null/100. Not scored: a blog is not measured on this.
- **pricing_legibility** null/100. Not scored: a blog is not measured on this.
- **agent_aware_instrumentation** 20/100. Robots.txt names claudebot and allows 14 AI agents, but no MCP manifest exists at the 3 standard paths checked. No llms.txt, ai-plugin.json or OpenAPI spec published.
- **machine_fetchable_trust** 40/100. The homepage answers automated requests with HTTP 200 and structured data. No security.txt file exists at /.well-known/security.txt. No Web Bot Auth signals are published.
- **commercial_rails** null/100. Not scored: a blog is not measured on this.
## The human door
- **steps_to_first_value** 80/100. The primary call to action, 'Get Started with Digital CS', is 2 steps from the homepage and leads to a signup form. The form is 2 steps away. A visitor reaches the entry point in 2 clicks and can begin reading content immediately after.
- **required_fields** 85/100. The signup form contains 2 fields total. 1 of 2 is required: 'Enter Email'. The other field is optional. A visitor can sign up with minimal friction by providing only an email address.
- **verification_walls** 65/100. The signup page does not display any verification requirement such as email confirmation, phone verification or CAPTCHA. A visitor can submit the form without evidence of a verification step appearing on the page itself, though.
- **error_recovery** 50/100. Of 3 form inputs on the signup page, 1 carries a validation rule and 1 carries a description. No inline error containers or live regions are present.
