John Mueller responded to how the third party can alter in unproven ways. As a result, John didn’t use third-party data like this.
Tweet From John:
I generally wouldn't use 3rd party tools to track things like this, they're always skewed in unexpected ways — use your actual traffic data instead.

Suggestion From John Mueller:
According to him, the user must be dependent on their traffic data rather on third party tool data. Further, he added that with their own data the user can search out the data in the way they not bt with third-party they cannot.
Moreover, the third-party metric does not match with your actual data. Therefore it is advised to use own data and does not depend on third-party metrics.
