Frequently asked
About historical authority
DA and PA are comparative Moz metrics. They are useful for trend analysis, but they are not direct Google ranking factors.
How far back does the history go?+
Moz can return up to 32 months of monthly history. The exact coverage depends on the data available for the domain.
Is this real historical Moz data?+
Yes. The chart uses Moz's official monthly site metrics history rather than estimated or fabricated past scores.
Why are some months missing?+
A month may be absent when Moz has no valid authority value for that domain in the relevant index.
Can DA change without losing backlinks?+
Yes. DA is comparative, so scores can shift when Moz updates its index or model and when other websites grow.
