Domain Authority

[Tom_Matthews]

Since we started using Moz our domain authority has dropped from 84 to 79. We can't figure this out. Is their someone we can discuss this with?

Tom,

Your use of Moz is unrelated to the drop in DA/PA.

There have been some recent changes that Rand addresses in this thread: https://moz.com/community/q/is-everybody-seeing-da-pa-drops-after-last-moz-api-update#reply_359883

For an overall explanation of fluctuations, try this link: https://moz.com/community/q/da-pa-fluctuations-how-to-interpret-apply-understand-these-ml-based-scores

Have a great day,

Matt
