AI Site Grade
czgroup.com — AI Site Grade
CZGroup.com serves a Florida car dealership to Anthropic's crawler but blocks all other AI bots and humans with a 403 from Akamai, creating a complete identity mismatch with the Czech defense conglomerate described by LLM knowledge.
The site is effectively invisible to all AI crawlers except Anthropic's, has zero external search presence, and suffers from a severe cold-knowledge identity mismatch.

Analysis
The Domain That Only Exists for One AI Crawler
The domain czgroup.com serves a completely different entity to anthropic-ai (a Florida car dealership) than what the cold-knowledge model describes (a Czech defense conglomerate), and blocks every other AI crawler and human browser with a 403 from Akamai.
Crawler Access
The site sits behind Akamai CDN (edgesuite.net) and returns 403 Forbidden to GPTBot, ClaudeBot, PerplexityBot, Google-Extended, OAI-SearchBot, ChatGPT-User, Bytespider, Applebot-Extended, and even standard browsers. The sole exception is anthropic-ai, which receives a 200 with 304KB of real HTML served from nginx. The robots.txt (accessible only to anthropic-ai) explicitly disallows GPTBot, OAI-SearchBot, ChatGPT-User, Claude-User, Claude-SearchBot, and PerplexityBot from /api/, /apis/, /pixall/, and static assets — but the Akamai WAF blocks these bots before they ever reach the robots.txt. No llms.txt exists on the non-www domain; the www subdomain serves a 1MB auto-generated llms.txt listing every inventory page.
Cold-Knowledge Gap
The LLM model describes czgroup.com as CZ Group, a Czech industrial and defense conglomerate — manufacturer of the CZ 75 pistol, BREN 2 rifle, and owner of Tatra trucks. The actual site is Craig Zinn Automotive Group, a multi-franchise car dealership in Hollywood, FL selling Acura, Lexus, Toyota, and Subaru. This is a complete identity mismatch. The domain czgroup.com appears to be a short vanity domain for "Craig Zinn" that happens to share initials with a major European arms manufacturer. No external search results surface for "Craig Zinn Automotive Group" anywhere on the open web.
Content and Schema Posture
The homepage title reads "Craig Zinn Automotive Group | New Acura, LEXUS, Toyota, Subaru Dealership in Hollywood, FL." The site runs on Dealer.com's DDC platform (ddc-site class). No JSON-LD schema was detected in any fetched page. The sitemap (708KB, accessible only to anthropic-ai) lists hundreds of inventory pages, a "Website Under Construction" page, and a /locations/index.htm page. The /about/index.htm returns a 404 — no about page exists. The "Website Under Construction" page is indexed and live, suggesting the site may be in an incomplete state.
External Signals
Zero external search results exist for "Craig Zinn Automotive Group" or "czgroup.com" across multiple search queries. The domain's DNS points to Akamai, with MX records pointing to cobaltgroup.com and dealer.com — confirming the Dealer.com platform. The site has no detectable backlinks, reviews, Reddit threads, or press mentions. For AI engines that cannot pass the Akamai WAF, this domain is effectively invisible.
Findings
Akamai WAF blocks all AI crawlers except anthropic-ai High
The site returns 403 Forbidden to GPTBot, ClaudeBot, PerplexityBot, Google-Extended, OAI-SearchBot, ChatGPT-User, Bytespider, Applebot-Extended, and standard browsers. Only anthropic-ai receives a 200 response with real HTML.
What to change: Configure Akamai WAF to allow major AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended) to access the site, or serve a static version of the content to bots.
LLM knowledge describes a Czech defense conglomerate, not the actual car dealership High
The LLM model identifies czgroup.com as CZ Group, a Czech industrial and defense conglomerate, but the site is Craig Zinn Automotive Group, a Florida car dealership. This complete identity mismatch undermines AI visibility.
What to change: Publish structured data (Organization schema) with the correct name, location, and industry to disambiguate the domain from the Czech entity.
No external search results for the dealership or domain High
Multiple web searches for 'Craig Zinn Automotive Group' and 'czgroup.com' returned zero results. The domain has no detectable backlinks, reviews, or press mentions, making it invisible to AI engines that rely on web signals.
What to change: Build external citations through local business listings, press releases, and backlinks from dealer franchises to establish the domain's identity.
No JSON-LD schema detected on any fetched page High
The homepage and other pages lack JSON-LD structured data, which is critical for AI crawlers to understand the site's content and entity relationships.
What to change: Add JSON-LD schema for Organization, LocalBusiness, and VehicleInventory to all pages.
Robots.txt disallows multiple AI bots from key paths Medium
The robots.txt (only accessible to anthropic-ai) explicitly disallows GPTBot, OAI-SearchBot, ChatGPT-User, Claude-User, Claude-SearchBot, and PerplexityBot from /api/, /apis/, /pixall/, and static assets. While the WAF blocks them anyway, this further restricts access.
What to change: Remove disallow rules for AI crawlers from robots.txt, or ensure the WAF allows them first.
About page returns 404 Medium
The /about/index.htm page returns a 404 error, meaning there is no about page for the dealership. This is a key page for establishing entity identity.
What to change: Create an about page with the dealership's history, location, and team information.
Website Under Construction page is indexed and live Medium
A 'Website Under Construction' page exists and is listed in the sitemap, suggesting the site may be incomplete. This can confuse crawlers and users.
What to change: Remove or redirect the under-construction page once the site is complete.
No llms.txt on the non-www domain Low
The non-www domain (czgroup.com) returns 403 for llms.txt, while the www subdomain serves a 1MB auto-generated file. This inconsistency may confuse AI crawlers.
What to change: Serve the same llms.txt on both domains or redirect the non-www to www.
Sitemap inaccessible to standard crawlers High
The sitemap.xml returns 403 to standard browsers and most AI crawlers, only accessible to anthropic-ai. This prevents search engines from discovering pages.
What to change: Allow all crawlers to access sitemap.xml by adjusting WAF rules.
What's working
- Anthropic crawler receives full HTML content — The anthropic-ai bot gets a 200 response with 304KB of real HTML, including inventory listings and location data, enabling Claude to index the site.
- Large sitemap with hundreds of inventory pages — The sitemap.xml (708KB) lists hundreds of inventory pages, providing a comprehensive map of the site's content for crawlers that can access it.
- Auto-generated llms.txt lists all inventory pages — The www subdomain serves a 1MB llms.txt file that lists every inventory page, providing a direct feed for AI crawlers.
- Homepage title clearly identifies the dealership — The title tag reads 'Craig Zinn Automotive Group | New Acura, LEXUS, Toyota, Subaru Dealership in Hollywood, FL', providing clear entity identification.
