capitolauto.com — AI Site Grade

Capitol Auto's Akamai edge blocks all AI crawlers except Anthropic, leaving the site invisible to GPTBot, Google-Extended, and PerplexityBot while serving no structured data and missing an About page.

Capitol Auto's selective crawler whitelist, missing schema, stale promotions, and zero external citations severely limit AI visibility.

Analysis

The site serves a full, rich homepage to anthropic-ai while returning a 403 to every other AI crawler and browser — a selective whitelist that leaves Claude as the only major model with direct access to the dealership's actual content.

Crawler Access

The site is hosted on Akamai (DNS points to dealer.com nameservers) with a dual-layer architecture: Akamai blocks all non-whitelisted traffic at the edge with a 403, while an internal nginx server serves content to approved user-agents. compare_bot_access confirmed that GPTBot, Google-Extended, ClaudeBot, PerplexityBot, ChatGPT-User, OAI-SearchBot, Applebot-Extended, and Bytespider all receive a 403. Only anthropic-ai gets a 200 with the full 430KB HTML page. The robots.txt is itself blocked by Akamai (403) for non-whitelisted crawlers, but when fetched as anthropic-ai it reveals rules that partially restrict GPTBot, OAI-SearchBot, ChatGPT-User, Claude-User, Claude-SearchBot, and PerplexityBot from JS, CSS, JSON, and API paths — though these bots never reach the file anyway. No llms.txt exists as a standard file; the site has a llms.txt that is a massive 416KB auto-generated link dump from the Dealer.com CMS, not a curated AI resource.

Cold-Knowledge Gap

The LLM's cold knowledge describes Capitol Auto as a "regional automotive dealership group" in the Pacific Northwest selling Toyota, Honda, and Subaru — but the actual site reveals six franchises: Cadillac, Chevrolet, Toyota, Subaru, Nissan, and a collision center. The cold knowledge omits Cadillac, Chevrolet, and Nissan entirely, and places the dealership in "Portland metro area" when the site's address is Salem, OR 97301. The cold knowledge mentions "family-owned and operated for decades" and "community involvement" — claims that cannot be verified from the site itself, which has no About page (returns 404) and no dealership history content.

Schema Posture

The homepage contains zero JSON-LD schema of any kind. The Wayback snapshot confirms the live site has no AutoDealer, Organization, or LocalBusiness structured data. The <title> tag and meta description are present, but no og:type or og:description are set. The site uses ddc-site as its CMS framework (Dealer.com), which typically supports schema injection — but none is active. The heading structure is flat: a single H1 ("Capitol Auto Group") followed by H2 and H3 for brand sections and promotions.

Stale Content and Missing Pages

The llms.txt contains a link titled "No Payments Until 2020" — a promotion that expired over five years ago. The page itself still exists and returns 200 with the title "No Payments Until 2020". The /about/index.htm page returns a 404 with a "Oops!" title, meaning there is no dealership history, team page, or brand story accessible. The sitemap lists 1,406 vehicle matches but the site has no FAQ, no comparison tables, and no answer-format signals that AI engines use for featured snippets. External search results for "Capitol Auto Group Salem" return zero indexed results — the site has no discoverable press mentions, reviews, Reddit threads, or third-party citations in the search index.

Findings

  1. Akamai blocks all AI crawlers except anthropic-ai High

    The site returns 403 to GPTBot, Google-Extended, ClaudeBot, PerplexityBot, ChatGPT-User, OAI-SearchBot, Applebot-Extended, and Bytespider. Only anthropic-ai receives a 200 with full content.

    What to change: Allow GPTBot, Google-Extended, and other major AI crawlers through Akamai's edge rules, or serve a static HTML version to all bots.

  2. Robots.txt is inaccessible to non-whitelisted crawlers High

    Fetching robots.txt as a regular browser or non-whitelisted bot returns a 403 from Akamai, preventing crawlers from reading crawl directives.

    What to change: Serve robots.txt publicly without authentication so all crawlers can read it.

  3. Homepage has zero JSON-LD structured data High

    The homepage contains no AutoDealer, Organization, or LocalBusiness schema. No structured data of any kind is present, which limits AI understanding of the dealership's identity and inventory.

    What to change: Add JSON-LD schema for AutoDealer, Organization, LocalBusiness, and VehicleOffer on relevant pages.

  4. About page returns 404 Medium

    The /about/index.htm page returns a 404 with an 'Oops!' title, meaning no dealership history, team, or brand story is available to crawlers or users.

    What to change: Create an About page with dealership history, team information, and location details.

  5. Stale 'No Payments Until 2020' promotion still live Medium

    The page /no-payments-for-4-months.htm still exists and returns 200 with a title referencing a promotion that expired over five years ago, which can mislead AI models and users.

    What to change: Remove or redirect the expired promotion page, or update it with current offers.

  6. llms.txt is a 416KB auto-generated link dump Low

    The llms.txt file is not a curated AI resource but a massive auto-generated list of URLs from the Dealer.com CMS, which is not useful for AI context.

    What to change: Replace the auto-generated llms.txt with a curated, concise file containing key pages and descriptions.

  7. No external search results for the dealership High

    Multiple web searches for 'Capitol Auto Group Salem' and related queries returned zero results, indicating no indexed press, reviews, or third-party citations.

    What to change: Build external citations through local business directories, press releases, and customer reviews.

  8. LLM cold knowledge omits three franchises and misstates location Medium

    The LLM's prior knowledge lists only Toyota, Honda, and Subaru, but the site sells Cadillac, Chevrolet, Toyota, Subaru, and Nissan. It also places the dealership in Portland instead of Salem, OR.

    What to change: Ensure accurate business information is published on the site and in structured data to correct LLM knowledge.

  9. No FAQ or comparison content for AI snippets Medium

    The site lacks FAQ pages, comparison tables, or answer-format content that AI engines use for featured snippets, reducing visibility in AI-generated answers.

    What to change: Create FAQ pages for common car-buying questions and comparison tables for vehicle models.

  10. Missing Open Graph tags on homepage Low

    The homepage has no og:type or og:description meta tags, which limits social sharing and AI understanding of page purpose.

    What to change: Add Open Graph tags including og:type, og:title, og:description, and og:image.
