Domain Authority History — track your DA over time
The Domain Authority History tool shows how a website’s Domain Authority score has moved across time, not just where it sits today. Instead of a single number, you get a DA trend — a timeline of historical Domain Authority values that reveals whether a domain is climbing, flat, or slipping. Because Domain Authority is a metric published by Moz, we surface the Moz DA history from a connected integration and display it exactly as reported. We read the numbers; we never invent or estimate them. When no provider is connected, the tool honestly reports insufficient evidence instead of guessing.
What a Domain Authority history tool is
A domain authority history tool is a way to view domain authority over time rather than as a one-off snapshot. A single DA score tells you where a domain stands right now; a history tells you the direction — the part that actually informs decisions. Domain Authority itself is a 1–100 score created by Moz to estimate a site’s relative ranking strength, based largely on its backlink profile. This tool takes that metric and lines up successive readings so you can track domain authority as a trend line.
Provider-dependent by design
DA history is only as trustworthy as its source, so this tool is deliberately provider-dependent. Every value on the chart comes from Moz, the authority behind the metric. We never generate, model, or interpolate Domain Authority values, and we never fill missing periods with placeholder numbers. If a Moz integration is not connected, you will see insufficient evidence — an honest, first-class result — rather than a fabricated line.
Why tracking DA over time matters
A single Domain Authority reading is easy to over-interpret. Watching Domain Authority over time turns a static number into an actionable signal:
Spot long-term trends
A rising DA trend over several months is a reassuring sign that your off-page efforts are compounding. A flat line may mean your link acquisition has stalled relative to competitors who are still earning references.
Measure the impact of link building
Because Domain Authority is driven heavily by your backlink profile, a history view lets you connect a campaign to its outcome. When you track domain authority before and after a digital-PR push or an outreach campaign, you can see whether new links moved the needle — and pair that with a Backlink Checker to confirm which links were actually gained.
Detect drops early
A declining trend can be an early warning. A sustained fall may follow lost or removed backlinks, a manual or algorithmic penalty, or a migration that broke link equity. Catching a downtrend in your historical Domain Authority gives you time to diagnose the cause before it compounds.
How to read a DA trend
Reading a Moz DA history chart well is mostly about telling normal movement apart from meaningful change:
Gradual growth is healthy
Domain Authority is a slow-moving, competitive metric — it is scored on a curve against every other domain on the web. Steady, incremental gains over months are exactly what a healthy, well-linked site looks like. Do not expect big weekly jumps; consistency in the DA trend matters more than speed.
Sudden drops warrant investigation
A sharp, isolated drop is worth a closer look. Start by checking whether you lost high-value backlinks, whether a referring domain went offline, or whether a site change coincided with the dip. Compare the timing against your own change log before assuming the worst.
Recalibrations are algorithm updates, not site changes
Moz periodically recalibrates the Domain Authority model. When it re-tunes the scale, many domains shift at once — so a movement that lines up with a known Moz update is usually a methodology change, not something your site did. This is the historical-comparison trap: never read a metric recalibration as a real change to your website. When in doubt, check whether competitors moved in the same direction at the same time.
DA is a comparative estimate, not a ranking factor
It is worth repeating because it changes how you should use this tool: Domain Authority is a comparative third-party estimate from Moz, not a Google ranking factor. Google does not use DA. Its value is in relative comparison — benchmarking your domain against competitors and against your own past — rather than as a promise of where you will rank. Use your domain authority history as a directional health check, and pair it with real search performance data before drawing conclusions.
Why we read the history from Moz and never fabricate
Domain Authority is Moz’s metric, and only Moz can produce an authentic value. That is why every point in your DA history is read from a connected Moz integration and displayed as-is. We do not estimate, smooth, or back-fill numbers, because an invented data point would be worse than no data at all — it would quietly mislead your decisions. When the provider cannot supply a value, we say so plainly with insufficient evidence. Honest gaps beat confident guesses.
Domain Authority history best-practices checklist
- Connect a Moz data source so historical Domain Authority can be read from the metric’s own publisher.
- Judge the DA trend over months, not days — Domain Authority moves slowly and competitively.
- Treat broad, simultaneous shifts as likely Moz recalibrations, not real site changes.
- Investigate sudden, isolated drops against your backlink profile and change log.
- Remember DA is a comparative estimate, not a Google ranking factor — benchmark, don’t obsess.
- Trust “insufficient evidence” — it means the data is real or absent, never invented.

Frequently asked questions
What is a domain authority history tool?
A domain authority history tool shows how a website’s Domain Authority (DA) score has changed over time instead of just its value today. It plots historical Domain Authority as a trend line so you can see whether a domain has been growing, holding steady, or declining. DA is a third-party metric created by Moz, so we surface the DA history from a connected Moz integration — we read the values, we never invent or estimate them.
Where does the domain authority history data come from?
Every point in the DA trend is read from Moz, the company that publishes the Domain Authority metric. When a Moz integration is connected, we display the historical Domain Authority values exactly as Moz reports them. If no provider is connected, we show “insufficient evidence” rather than guessing — we will never fabricate a DA history or fill gaps with made-up numbers.
Is Domain Authority a Google ranking factor?
No. Domain Authority is a comparative, third-party estimate produced by Moz to predict how well a site might rank. Google does not use DA and has confirmed it is not part of its algorithm. Treat DA history as a useful benchmarking signal for comparing sites and tracking your own progress over time, not as a direct measure of how Google ranks you.
Why did my Domain Authority drop even though nothing changed?
Moz periodically recalibrates the Domain Authority model. When the underlying scale is re-tuned, many domains shift up or down at once even though their real link profiles did not change. So a sudden, broad DA movement can be an algorithm update on Moz’s side rather than a genuine change to your site. A gradual, sustained drop that coincides with lost links or a penalty is more likely to be a real signal worth investigating.
Is this domain authority history checker free?
Yes, the tool is free to use. It reads the Domain Authority over time from the connected Moz data source and displays the trend — nothing is invented or estimated. Where a provider is unavailable, the result is shown as “insufficient evidence” so you always know the data is real.
