pierreauto.com — AI Site Grade

Pierre Auto Group's site is entirely invisible to every AI crawler except Anthropic's, with a 547KB llms.txt that only Claude can read and zero external web presence.

Pierre Auto Group has invested in AI-readiness infrastructure but locked it behind a single-crawler whitelist, leaving the site invisible to all other AI systems and search engines.

Analysis

I have enough information now to write the audit. Let me compile the key findings.

Key findings: 1. The site is behind Akamai (AkamaiGHost) which blocks ALL traffic except anthropic-ai — which gets routed to an nginx backend with full content (311KB). 2. The anthropic-ai bot bypasses Akamai entirely and hits nginx directly — this is a deliberate whitelist setup. 3. DNS has an anthropic-domain-verification TXT record — Pierre Auto Group proactively verified their domain with Anthropic. 4. They have an llms.txt (547KB, hundreds of URLs) but it's only accessible to anthropic-ai — everyone else gets 403. 5. robots.txt is also 403 to browsers but accessible to anthropic-ai — it blocks GPTBot, OAI-SearchBot, ChatGPT-User, Claude-User, Claude-SearchBot, PerplexityBot, etc. from JS/CSS/JSON/API paths. 6. Cold LLM knowledge thinks they sell Ford, Lincoln, Mazda — but the site actually sells Chrysler, Chevrolet, Ford, Dodge, GMC, Jeep, Lincoln, Ram, Isuzu. No Mazda. Major brand mismatch. 7. No JSON-LD schema detected on homepage. 8. No external search results found — zero web presence outside their own domain. 9. The site is built on Dealer.com platform (ddc-site class).

Let me write the audit.

Pierre Auto Group: A Site That Only Exists for Claude

The site is entirely invisible to every AI crawler except Anthropic's — and even the anthropic-ai bot sees a completely different infrastructure than everyone else.

Crawler Access: Akamai vs. Nginx Split

compare_bot_access on https://www.pierreauto.com returned 403 blocked for GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, PerplexityBot, Google-Extended, Applebot-Extended, Bytespider, and even a standard browser. All hit AkamaiGHost and get a 15-byte "Access Denied" page. The sole exception is anthropic-ai, which gets a 200 with 311KB of full HTML served from nginx — a completely different backend. The DNS TXT records confirm deliberate setup: an anthropic-domain-verification token is present, alongside google-site-verification and apple-domain-verification. The site verified with Anthropic but apparently did not verify with OpenAI, Google, or Perplexity for crawler access.

The llms.txt That Only One Bot Can Read

The site hosts a 547KB llms.txt containing hundreds of URL listings — an unusually large and detailed AI content map. However, it returns 403 to any browser or non-Anthropic crawler. Only anthropic-ai can read it. The robots.txt (also 403 to browsers) permits anthropic-ai while explicitly disallowing GPTBot, OAI-SearchBot, ChatGPT-User, Claude-User, Claude-SearchBot, PerplexityBot, and others from JS/CSS/JSON/API paths. The net effect: the site has invested in AI-readiness infrastructure (llms.txt, sitemap.xml with daily/weekly priorities) but made it accessible to exactly one crawler.

Cold-Knowledge Gap: Brands and Location

An LLM queried cold about "Pierre Auto Group Seattle" described it as selling Ford, Lincoln, and Mazda — but the actual site sells Chrysler, Chevrolet, Ford, Dodge, GMC, Jeep, Lincoln, Ram, and Isuzu. No Mazda. No mention of the multi-franchise Stellantis/GM/Ford mix. The cold knowledge also placed locations in Lynnwood and other cities, while the site lists a single address: 12620 Highway 99, South Everett, WA 98204. The site's title tag says "Seattle's Pierre Auto Group" but the physical location is in Everett, 25 miles north.

Schema and External Signals

The homepage contains zero JSON-LD schema — no AutoDealer, LocalBusiness, or Organization markup. The site runs on the Dealer.com platform (evident from ddc-site CSS classes and pictures.dealer.com asset domain), which typically includes structured data by default, suggesting it was stripped or misconfigured. External search for reviews, Reddit mentions, or press coverage returned zero results across multiple queries — the brand has no detectable off-domain footprint that would feed AI training data or knowledge graph enrichment.

Findings

  1. Akamai blocks all crawlers except anthropic-ai High

    The site uses Akamai to block every AI crawler and browser, returning a 403 'Access Denied' page. Only the anthropic-ai bot bypasses Akamai and reaches an nginx backend with full content.

    What to change: Remove the Akamai block for other AI crawlers (GPTBot, OAI-SearchBot, etc.) or configure Akamai to allow them through to the nginx backend.

  2. llms.txt returns 403 to all non-Anthropic crawlers High

    The 547KB llms.txt, containing hundreds of URLs, is only accessible to the anthropic-ai bot. Browsers and other crawlers receive a 403 error, defeating its purpose as an AI content map.

    What to change: Make llms.txt publicly accessible by removing the Akamai block for that path.

  3. robots.txt blocks GPTBot, OAI-SearchBot, and others High

    The robots.txt file, only readable by anthropic-ai, explicitly disallows GPTBot, OAI-SearchBot, ChatGPT-User, Claude-User, Claude-SearchBot, PerplexityBot, and others from JS/CSS/JSON/API paths, limiting their ability to crawl the site.

    What to change: Remove disallow rules for AI crawlers or allow them access to all content.

  4. Homepage lacks JSON-LD structured data High

    The homepage contains zero JSON-LD schema markup for AutoDealer, LocalBusiness, or Organization, which are critical for AI systems to understand the business and its inventory.

    What to change: Add JSON-LD structured data for AutoDealer, LocalBusiness, and Organization to the homepage.

  5. Cold LLM knowledge lists wrong brands and location Medium

    An LLM queried about Pierre Auto Group reported selling Ford, Lincoln, and Mazda, but the site actually sells Chrysler, Chevrolet, Ford, Dodge, GMC, Jeep, Lincoln, Ram, and Isuzu. The cold knowledge also placed locations in Lynnwood instead of the single Everett address.

    What to change: Publish accurate brand and location information in structured data and on the site to correct LLM knowledge.

  6. No external search results or reviews found Medium

    Multiple web searches for the dealership name, reviews, and mentions returned zero results. The brand has no detectable off-domain footprint that would feed AI training data or knowledge graphs.

    What to change: Build external presence through Google Business Profile, dealer review sites, and local citations.

  7. Title tag says 'Seattle' but physical location is in Everett Low

    The homepage title tag reads 'Seattle's Pierre Auto Group' but the physical address is 12620 Highway 99, South Everett, WA 98204, 25 miles north of Seattle.

    What to change: Update the title tag to accurately reflect the Everett location.
