Jenkins Auto Group: A Site That Only Exists for One AI Crawler

The entire jenkinscars.com domain returns HTTP 403 "Access Denied" to every browser and every major AI crawler tested — except one: anthropic-ai gets a full 200 with ~383KB of content, while GPTBot, ClaudeBot, PerplexityBot, Google-Extended, OAI-SearchBot, and ChatGPT-User all hit Akamai's WAF wall.

Crawler Access

The robots.txt file exists but is itself blocked by Akamai to browser UAs (returns 403). Only the anthropic-ai bot can read it. The file contains explicit Disallow rules for GPTBot, OAI-SearchBot, ChatGPT-User, Claude-User, Claude-SearchBot, and CCBot — but these restrictions are redundant since the Akamai WAF blocks those bots at the network layer before they ever reach the robots.txt. The llms.txt file is a massive 1.7MB document listing hundreds of pages with descriptions — a strong AI-readiness signal — but it is only accessible to the anthropic-ai bot. Every other bot and browser gets a 403 on the homepage, all subpages, the sitemap, and the robots.txt itself. The site runs on Akamai CDN with a strict WAF rule that appears to whitelist only the anthropic-ai user-agent string.

Cold-Knowledge Gap

LLM knowledge of "Jenkins Cars" is effectively zero. The model reports no awareness of the brand, no dealership locations, no products, no reviews, no news. The site itself is a multi-franchise auto group (Jenkins Auto Group) selling Acura, Honda, Hyundai, Kia, Mazda, Nissan, Ford, Chevrolet, Chrysler, Dodge, Jeep, Ram, Volkswagen, Subaru, Volvo, Genesis, and Lincoln across locations in Venice, Crystal River, Leesburg, Jacksonville, and Gainesville, Florida. The gap between what the site actually is (a major 15+ brand dealer network) and what AI models know about it (nothing) is near-total — driven entirely by the WAF blocking all non-Anthropic crawlers.

Content & Schema

The homepage title reads "Jenkins Auto Group | New & Used Cars for Sale in Florida." The site is built on the Dealer.com (DDC) platform (ddc-site CSS class), a common automotive dealership CMS. The HTML contains no visible JSON-LD structured data in the fetched excerpts. The Hyundai FAQ page has a title referencing "Hyundai Dealership in Fayetteville, NC" — a North Carolina location that contradicts the Florida-only positioning of the rest of the site, suggesting stale or template-copied content. The sitemap contains hundreds of URLs including brand-specific pages, service centers, collision repair, and FAQ pages, all with lastmod dates of 2026-05-30 (a future date), indicating a systemic timestamp issue.

External Signals

Web searches for "Jenkins Auto Group" return zero indexed results across multiple queries. No Google Maps listings, no dealer review sites, no Reddit threads, no press mentions appear in search results. This is consistent with the Akamai WAF blocking Googlebot entirely — the site is effectively invisible to Google's index. The DNS records show the domain uses GoDaddy nameservers and Proofpoint email security, but no external citation footprint exists.

Findings

1. Akamai WAF blocks all browsers and most AI crawlers High

   The entire domain returns HTTP 403 Access Denied to browser user agents and all tested AI crawlers except anthropic-ai. GPTBot, ClaudeBot, PerplexityBot, Google-Extended, OAI-SearchBot, and ChatGPT-User are all blocked at the network layer.

   What to change: Remove the Akamai WAF rule that blocks non-anthropic-ai user agents, or replace it with a permissive rule that allows all legitimate crawlers and browsers.

2. Robots.txt inaccessible to browsers and most bots High

   The robots.txt file returns 403 to browser user agents, making it unreadable by most crawlers. Only the anthropic-ai bot can fetch it.

   What to change: Allow browser and standard crawler access to robots.txt by adjusting the WAF rule.

3. LLMs.txt only accessible to anthropic-ai bot High

   The llms.txt file is a comprehensive 1.7MB document listing hundreds of pages, but it is only served to the anthropic-ai bot. Other AI crawlers and browsers receive a 403.

   What to change: Make llms.txt publicly accessible to all user agents by removing the WAF restriction.

4. Zero search engine indexing due to WAF blocking Googlebot High

   Web searches for the domain and brand return zero results. Googlebot is blocked by the WAF, so no pages are indexed.

   What to change: Allow Googlebot and other search engine crawlers through the WAF to enable indexing.

5. LLMs have no knowledge of Jenkins Cars brand High

   The LLM knowledge base contains no information about Jenkins Cars, its dealership locations, or its inventory. The brand is effectively unknown to AI models.

   What to change: Allow AI crawlers (e.g., GPTBot, ClaudeBot, Google-Extended) to access the site so LLMs can learn about the brand.

6. No JSON-LD structured data on key pages Medium

   The homepage and other fetched pages contain no visible JSON-LD structured data, which limits rich snippet eligibility and AI understanding of the business.

   What to change: Add JSON-LD structured data for LocalBusiness, AutoDealer, and VehicleOffer schemas to all relevant pages.

7. Hyundai FAQ page references incorrect location Medium

   The Hyundai FAQ page title mentions 'Hyundai Dealership in Fayetteville, NC', which contradicts the Florida-only positioning of the rest of the site, indicating stale or template-copied content.

   What to change: Update the Hyundai FAQ page to reflect the correct Florida location(s) and remove any North Carolina references.

8. Sitemap contains future lastmod dates Medium

   The sitemap lists lastmod dates of 2026-05-30 for hundreds of URLs, which is a future date. This may confuse crawlers and reduce trust in the sitemap.

   What to change: Correct the sitemap generation to use accurate lastmod dates instead of a fixed future date.

9. Sitemap inaccessible to browsers and most bots High

   The sitemap.xml returns 403 to browser user agents, preventing search engines from discovering the site's URL structure.

   What to change: Allow browser and standard crawler access to sitemap.xml by adjusting the WAF rule.

10. No external citations or reviews found online Medium

    Web searches for the brand and dealership names return zero results, indicating no external citations, reviews, or press mentions exist online.

    What to change: Build external citations by claiming Google Business Profile listings, encouraging reviews, and engaging in local SEO.
