Observations
Observations are neutral facts. They are never pass or fail, never warnings, and never part of the Technical Score.
HTTP-REDIRECT-002Observation · not scoredRedirect hopsHTTP and retrievalTechnical Search
- What is reported
- The number of redirects followed to reach the final URL (0 when none).
- Why it is not a rule

- Whether MaxiMarket received the page content (retrieved) or an access-control, bot-challenge or authentication page (blocked). Reported also for blocked results.
- Why it is not a rule
- MaxiMarket's network and user agent are not a search crawler's, so a block here is evidence, not proof that crawlers are blocked.

CRAWL-POLICY-001Observation · not scoredDeclared crawler policyAI crawler access and policyTechnical SearchAI Discovery
- What is reported
- For the audited URL and every crawler in the 2026.4 crawler registry (search, AI search, AI agent, AI training and other known crawlers): allowed, partially-restricted (the URL is allowed but the applicable group disallows other paths) or disallowed, each with "-by-default" when no group names the crawler (inherited from the * group, or no rules). Present when robots.txt was retrieved, or returned 404/410, and could be fully inspected, also when the page itself was not retrieved.
- Why it is not a rule
- Which crawlers a site allows is the owner's policy, never a defect. robots.txt states preferences; it does not enforce access and does not show that a crawler can reach the page.
