Ranked, unranked or no data
To know whether your app is ranked on a keyword or not, you can refer to the following logic in the response data:
value= non-null andfetch_performed = true➔ rankedvalue= null andfetch_performed = true➔ unrankedvalue=nullandfetch_performed = false➔ no dataIn addition to
value, you can useeffective_value, that corresponds to a value that is guaranteed to be non-null. The logic to computeeffective_valueis:
- If
valueis notnull,effective_value = value- Otherwise
- If
fetch_performed = true, theneffective_value = 501, corresponding to the numeric representation ofunranked- Otherwise
- If there is at least one non-null value in the date range, take the closest day to the missing day and use that
valuefor theeffective_value(use an average if 2 days are at the same distance to the missing day)- Otherwise, defaults to
501
