limitations: A commercial web index. It only records pages it has crawled; small sites are crawled infrequently; "lost" status can lag reality by months; history for navigator.ca begins in 2015 and for navigatormm.com in 2013. Access requires a subscription, so the raw export is reproducible only by another subscriber.

Third-party crawler and link index used to enumerate websites that link to Navigator's domains with a footer credit. The index is independent of Navigator; the filtering and classification applied to it were performed by Navigator's agent and are recorded as DERIVED evidence.
