Can AI agents and search engines reach and list your pages?

25% of your grade · 9 of 10 goals pass

  • Agents can reach your siteCriticalPass

    Cloudflare's scan reached your site. An agent that is refused at the door reads nothing. Claude's web fetch tool gets only what a site answers to its request, so a firewall that challenges or blocks automated requests leaves it without your page.

    Web fetch tool, AnthropicReport an issue with this check

  • AI crawlers are allowed to read your siteCriticalPass

    Your robots.txt allows all 20 of the AI crawlers Cloudflare checks. A crawler is a robot that reads sites for a search engine or assistant, and one that is blocked cannot recommend you. OpenAI, Anthropic and Perplexity each say their crawlers follow robots.txt.

    Overview of OpenAI crawlers, OpenAIReport an issue with this check

  • Search engines may list each pageCriticalPass

    Page isn’t blocked from indexing Google leaves out a page marked noindex, and a page its crawler cannot read cannot be listed or used as a supporting link in its AI features.

  • Your robots.txt is one robots can followImportantPass

    robots.txt is valid Google says a robots.txt file tells crawlers which addresses they may request. A line a crawler cannot read is skipped, so a rule you meant to set may never apply.

  • Your pages are listed in a sitemapImportantPass

    sitemap.xml exists with valid structure. Google and Bing use an XML sitemap to find your pages, and neither promises to index every page in it. A page must be indexed to appear in Google's AI answers.

  • Every page has its own titleImportantPass

    Document has a <title> element Google builds the title link in search results from the page's title, and may change one that is missing, vague, boilerplate or repeated. A title keeps your wording in front of searchers.

  • Pages that do not exist say soImportantPass

    A page that does not exist answers 404. Google treats content behind a 404 or 410 as gone, and flags empty pages that answer 200 (success) as soft 404s.

  • A short guide to your site for AI assistantsImportantFail

    Your site does not publish /llms.txt. llmstxt.org proposes the file so assistants find what they need and follow its links. Lighthouse audits it as an emerging convention, and the grade counts a standard that is likely to be adopted.

    • Lighthouse found no /llms.txt: https://arrissomerville.com/

    What to do Publish /llms.txt with your business name as its title and links to your most important pages.

    For your web team: Serve a Markdown file at /llms.txt with a 200, and keep it out of the way of any rule that routes unknown paths to the home page or answers them with a firewall page. Start it with an H1 naming the site, then sections of Markdown links to key pages, as llmstxt.org describes.

  • Your AI tools are listed in an AI catalogImportantFail

    Your site does not publish an ARD catalog at /.well-known/ard.json. The Agentic Resource Discovery (ARD) draft is a format that helps assistants discover what a site offers, such as tools and agents. Lighthouse audits the catalog, and the grade counts a standard that is likely to be adopted.

    • Lighthouse found no ARD catalog at /.well-known/ard.json: https://arrissomerville.com/

    What to do Publish an ARD catalog once your site has an MCP server or agent to list.

    For your web team: Serve a JSON file at /.well-known/ard.json with an entries list that follows the ARD schema: each entry carries a urn:air: identifier, a displayName, a type and a url. An MCP server's entry has the type application/mcp-server-card+json and points at its server card, at /mcp/server-card. Name the catalog from every page with <link rel="ard" href="/.well-known/ard.json">. Lighthouse reads that path and warns about a catalog it finds only at the older /.well-known/ai-catalog.json.

  • Your pages answer in Markdown when an agent asksImportantFail

    Site does not support Markdown for Agents. Cloudflare calls Markdown the common language of agents: its explicit structure gives better results and wastes fewer tokens, and an agent asks for it with an Accept header.

    • Site does not support Markdown for Agents: https://arrissomerville.com/

    What to do Serve each page as Markdown to agents that ask for it.

    For your web team: Answer a request whose Accept header names text/markdown with the page's content as Markdown and Content-Type: text/markdown. Cloudflare can convert pages at its edge, or the server can render the Markdown itself.

    • No Content Signals found in robots.txt: https://arrissomerville.com/

    What to do Decide whether your content may be used for search, AI answers and AI training, and ask the people who run your site to say so in robots.txt.

    For your web team: Add a Content-Signal line to robots.txt under the user agents it covers, such as Content-Signal: search=yes, ai-input=yes, ai-train=no.

  • Your key facts are in the page itselfCriticalPass

    Your home page holds 368 words before any script runs. Claude's web fetch tool does not support pages that fill in their text with JavaScript, and Google reads such a page only after its first HTML, once it reaches the rendering queue. A page whose first response is empty waits or looks empty.

  • Your business is described in structured dataImportantPass

    The home page's structured data names ApartmentComplex, PostalAddress, GeoCoordinates, and OpeningHoursSpecification. Structured data spares an assistant from guessing what a page means. Google says it gives explicit clues about a page; Bing says it may support clearer grounding and promises nothing.

  • Lists and tables are built as lists and tablesImportantPass

    All 2 audits in this goal pass. WCAG, the web accessibility standard most laws point to, requires the structure a page shows on screen to be in its markup as well, and the axe rules check lists and tables for it.

  • Every page has its own summary for search resultsImportantPass

    Document has a meta description Google can show a page's meta description as its snippet and asks for a different one on every page. It is less likely to show a list of keywords, so a specific summary has the best chance of being used.

    How to Write Meta Descriptions, GoogleReport an issue with this check

    All 3 audits in this goal pass. WCAG requires the language of each page to be set in its code, so software reads it with the right rules and voice.

  • Agents can discover your MCP serverMust haveImportantFail

    Your site has no ARD catalog at /.well-known/ard.json, so an agent cannot discover an MCP server from it. ARD is how an agent finds what a site offers from its domain alone, and the MCP project accepted server cards so that a client can discover a server before it connects.

    • Status 404: https://arrissomerville.com/.well-known/ard.json

    What to do Run an MCP server for your main actions and list it in the site's ARD catalog.

    For your web team: Serve the MCP server card at /mcp/server-card, as the server card extension places it, and list it in /.well-known/ard.json as an entry with a urn:air: identifier, a displayName, the type application/mcp-server-card+json and the card's URL.

  • Text is readableImportantPartial

    Background and foreground colors do not have a sufficient contrast ratio. WCAG requires text to contrast with its background by at least 4.5 to 1, and the axe rule color-contrast checks for it.

    • Fix any of the following: Element has insufficient color contrast of 3.66 (foreground color: #ffffff, background color: #cb6c2f, font size: 8.3pt (11px), font weight: normal). Expected contrast ratio of 4.5:1: <span class="vertaligner-primary">: https://arrissomerville.com/

    What to do Darken pale text and underline the links inside paragraphs.

  • Buttons and links are big enough to tapImportantPartial

    Touch targets do not have sufficient size or spacing. web.dev recommends tap targets of around 48 pixels, and WCAG sets a minimum of 24 by 24 pixels.

    • Fix any of the following: Target has insufficient size (7px by 7px, should be at least 24px by 24px) Target has insufficient space to its closest neighbors. Safe clickable space has a diameter of 10px instead of at least 24px.: <a href="#" class="homepage__gallery-active">: https://arrissomerville.com/

    What to do Make small buttons and tightly packed links bigger on phones.

    For your web team: Make each target at least 24 by 24 CSS pixels, or leave enough space around smaller ones, and aim for around 48 pixels. Set width=device-width in the viewport tag so taps answer at once.
