The Data score on domain authority APIs

This score, out of 100, shows how much of a domain's data a provider's call returns. We send each domain to the provider's call. Where a call asks for a country, we set the United States. For each domain, we count the parts the answer held, such as the authority score and the backlinks. We divide that count by the parts we count for the domain. We count a part when a live call that offers the part returned it for the domain. On a domain where fewer than two live calls offer the part and return data, we count the part when any call returned it. Then we average the results over all domains. Each domain counts the same. When a provider didn't find a domain, we count that domain as 0. We compare a provider that ran on fewer domains with the other providers on those same domains. A provider can't score higher by running only on easy domains. We lower the score when we test the call on fewer domains than the benchmark has.
