AI Site Grade
mossbrosautogroup.com — AI Site Grade
Moss Bros Auto Group's Akamai firewall blocks all major AI crawlers except Anthropic, while the site has zero search engine presence and no structured data.
The site is effectively invisible to AI and search engines due to an Akamai WAF that 403s all standard bots except Anthropic, combined with zero indexed pages, no schema, and a robots.txt that contradicts the firewall.

Analysis
Akamai Firewall Blocks All Major AI Crawlers While Allowing Only Anthropic
The site's Akamai WAF returns HTTP 403 to GPTBot, Google-Extended, PerplexityBot, ClaudeBot, ChatGPT-User, OAI-SearchBot, and even standard browsers -- yet the anthropic-ai user-agent receives a 200 with 522KB of full HTML content served from a separate nginx origin. This creates a bizarre single-bot whitelist that contradicts the site's own robots.txt.
Crawler Access
The robots.txt (accessible only via the anthropic-ai UA) partially disallows GPTBot, OAI-SearchBot, ChatGPT-User, Claude-User, Claude-SearchBot, and PerplexityBot from JS/CSS/JSON/api/pixall paths -- but does not disallow the root. The Akamai layer overrides this entirely: every bot except anthropic-ai hits a 403 wall before reaching the nginx origin. Google-Extended, Applebot-Extended, and Bytespider all get blocked at the edge. The llms.txt returns a connection error (no DNS resolution). The sitemap.xml is also 403'd to standard UAs but returns 200 to anthropic-ai, revealing 474KB of URLs with lastmod dates as far out as 2026-05-30 -- a future timestamp that signals a misconfigured CMS or stale cache.
Content and Schema Posture
The site runs on Dealer.com (DDC) platform and sells Volkswagen, Dodge, Jeep, Toyota, Chevrolet, Chrysler, GMC, Honda, and Ram vehicles across 8 locations in Riverside, San Bernardino, and Moreno Valley. The homepage title and meta descriptions are present, but no JSON-LD schema was detected in any fetched page. The inventory page (/all-inventory/index.htm) and specials page (/all-inventory/specials.htm) exist and return full HTML, but the site lacks standard pages like /about-us, /contact, /finance, and /testimonials -- all return 404. A community car wash page and a "buying after bankruptcy" guide exist, indicating some content marketing, but no FAQ, comparison tables, or structured answer-format signals were found.
Cold-Knowledge Gap
The LLM knows Moss Bros Auto Group as a Southern California multi-franchise dealer group with Honda, Toyota, Nissan, Hyundai, Kia, and Ford -- but the actual site sells none of those brands. The real inventory includes Volkswagen, Dodge, Jeep, Chrysler, Chevrolet, GMC, Ram, and pre-owned vehicles. The LLM also describes a "strong local presence in Riverside and San Bernardino counties" and "average to positive reputation" -- but no external reviews, Reddit threads, press mentions, or search results for the domain could be found anywhere. The brand has zero indexed pages in search engines, zero external citations, and zero review profiles discoverable through public search.
External Signals
No external mentions of mossbrosautogroup.com were found in search results, review sites, or news. The domain's MX record points to mail.mosssavings.com (a separate brand), and the SPF record references a Mailgun integration. The DNS includes two Google site verification tokens, suggesting past Search Console setup, but no pages appear in Google's index. The Akamai edge configuration blocks all standard traffic, making the site effectively invisible to both human visitors and AI crawlers except for a single Anthropic bot path.
Findings
Akamai WAF blocks all major AI crawlers except Anthropic High
The Akamai edge returns HTTP 403 to GPTBot, Google-Extended, PerplexityBot, ClaudeBot, ChatGPT-User, OAI-SearchBot, and standard browsers, while allowing only the anthropic-ai user-agent with a 200 response. This single-bot whitelist contradicts the site's own robots.txt and makes the site invisible to most AI crawlers.
What to change: Reconfigure the Akamai WAF to allow standard AI crawler user-agents (GPTBot, Google-Extended, PerplexityBot, etc.) to access the site, or implement a more granular access policy that respects robots.txt directives.
Robots.txt partially disallows AI bots but is overridden by firewall High
The robots.txt (accessible only via anthropic-ai UA) disallows GPTBot, OAI-SearchBot, ChatGPT-User, Claude-User, Claude-SearchBot, and PerplexityBot from JS/CSS/JSON/api/pixall paths, but does not disallow the root. However, the Akamai firewall blocks these bots before they reach the origin, making the robots.txt directives irrelevant.
What to change: Update robots.txt to allow all AI crawlers access to the root and remove disallow directives that conflict with the firewall policy. Ensure the firewall allows these bots.
No JSON-LD structured data on any page High
No JSON-LD schema was detected in any fetched page, including the homepage, inventory, specials, and service pages. This means AI crawlers cannot extract structured information about the dealership, inventory, or services.
What to change: Add JSON-LD structured data for LocalBusiness, AutoDealer, Vehicle, and FAQ schemas to all relevant pages.
Zero pages indexed in search engines High
No pages from mossbrosautogroup.com appear in search engine results. Web searches for the domain and brand returned zero results, indicating the site is completely invisible to search engines.
What to change: Ensure the site is accessible to search engine crawlers by adjusting the Akamai firewall, submitting a sitemap to Google Search Console, and resolving any indexing issues.
Sitemap contains future lastmod dates (2026-05-30) Medium
The sitemap.xml (accessible only via anthropic-ai) lists URLs with lastmod dates as far out as 2026-05-30, indicating a misconfigured CMS or stale cache. This can confuse crawlers and harm indexing.
What to change: Fix the CMS configuration to generate accurate lastmod dates and regenerate the sitemap.
Standard pages (about, contact, finance) return 404 Medium
Pages like /about-us, /contact, /finance, /testimonials, /inventory, /used-inventory, /new-inventory, and /search all return 404 errors. This limits the site's ability to provide essential information to AI crawlers and users.
What to change: Create and publish standard pages for about, contact, finance, and testimonials with relevant content.
LLM knowledge about the brand is outdated and incorrect Medium
The LLM describes Moss Bros Auto Group as selling Honda, Toyota, Nissan, Hyundai, Kia, and Ford, but the actual inventory includes Volkswagen, Dodge, Jeep, Chrysler, Chevrolet, GMC, and Ram. This mismatch can lead to fabricated facts when AI answers queries about the dealership.
What to change: Publish accurate brand and inventory information on the site with structured data to correct the LLM's knowledge.
No external citations, reviews, or press mentions found Medium
Web searches for the domain and brand returned zero results from review sites, news, or any external sources. This lack of external signals reduces the site's authority and discoverability.
What to change: Build external citations by claiming business listings on Google My Business, Yelp, and other directories, and encourage customer reviews.
llms.txt file returns connection error Low
The llms.txt file at mossbrosautogroup.com/llms.txt is unreachable due to a connection refused error, meaning AI crawlers cannot discover the site's AI-specific content hints.
What to change: Create and serve an llms.txt file with a summary of the site's content and AI-relevant resources.
No FAQ, comparison tables, or structured answer-format content Low
The site lacks FAQ pages, comparison tables, or other structured answer-format content that AI crawlers can use to extract direct answers. This limits the site's ability to appear in AI-generated answers.
What to change: Add FAQ schema and create comparison pages for vehicle models to provide structured answer content.
