This page answers the questions covered by the article Can AI Search Read Your Site? A 45-Minute curl and CDN Audit on groas.com. The article is the full, canonical source.
Direct answer: According to groas, a site that looks fine in a browser may still hand an AI search crawler a 403, a challenge page or an empty HTML shell. The article recommends a 45-minute audit of a homepage, one commercial landing page and one high-traffic informational or pricing page to build a three-page inventory: what the server returns to AI user-agent strings, whether answer text and schema exist before JavaScript runs, and whether logs show credible crawler visits. A fetch is not a citation; the audit checks whether pages can be fetched and read and uses logs to distinguish routine crawling from requests for particular answers.
The article recommends testing the same three URLs throughout with five AI user-agent strings, saving response headers and body separately and repeating the fetch for each page. The expected result is a final 200 with an HTML body containing the page, not a login screen, error page or challenge; a 403 or 503 is a failure and a 200 containing challenge text is not a pass. A header-only check is not proof because it does not request the body, and anyone can supply a bot string, so this test only shows how the edge handles the string from that connection.

The article recommends choosing a distinctive sentence or pricing phrase visible on the page and searching for it in the saved fetch body and in a fresh raw dump. The expected result is that the phrase appears with its heading and useful body copy around it; one matching word in a navigation link is not enough. If the browser shows the answer but the response contains little beyond <div id="root"></div> and script tags, the article describes it as a rendering problem to fix with server-side rendering (SSR) or static site generation (SSG), not a copywriting problem.

According to groas, blocking model training and blocking search retrieval are different decisions and a blanket rule can conflate them. The article recommends opening the live https://yourdomain.com/robots.txt file, finding every group for named training, search and user-requested agents plus any User-agent: * group, and reviewing a pattern that disallows the named training crawlers while allowing the named search and user-requested agents. Robots.txt tells compliant crawlers what they may request; it cannot make a firewall deliver a blocked page and does not stop an uncooperative scraper.

The article recommends checking the saved response for a <script type="application/ld+json"> block and for the page's main <h1>, useful <h2> headings and answer text before scripts run. The expected result is that intended schema appears in the returned HTML and headings and content form a readable page, with the Product, Organization or FAQPage data relevant to that URL actually present. Missing structured data is a missing source-of-context check, not proof citations are impossible, and if schema appears only after the tag container runs, the article says to move its generation into the initial HTML.

The article recommends filtering request logs for the three URLs by path and user-agent and recording status, transferred bytes and remote IP, then running a reverse lookup on the IP followed by a forward lookup on the returned hostname. For a crawler verified by DNS, the reverse hostname belongs to its stated operator and the forward lookup resolves back to the original IP; an unrelated hostname or unmatched lookup does not support the claimed identity. In its infrastructure audit, more than 80% of incoming traffic that looked like bot traffic was scrapers borrowing its name, 13,416 robots.txt hits in a month were permission checks, and four pages accounted for 91.5% of AI-answer fetches, so the article advises looking for credible requests to pages with answers that received full 200 responses.
