The Data score on cached company hierarchy APIs: Out of 100: the share of companies the call returned a hierarchy for. A hierarchy means the provider found the company at its domain and listed at least one other company of its group. We score a company only if its LinkedIn page links to another company of its group, like a parent or a subsidiary. Some company pages link only to their own brand pages. Pages on the company's own website, like an office page or a program page, count as brand pages too. Those companies may have no group, so we leave them out. We don't check the companies the provider lists. Only the provider knows how big a group is. A provider we called more than once on the same company is scored on all those calls, so no one run decides it. Each provider here answers from a copy it keeps. We then lower the score to the lowest score we are 95% sure the call earns. We lower the score more when we test fewer companies.
