Current DR
The latest value comes from Ahrefs' public Domain Rating endpoint when the server key is configured.
Free SEO authority tool
Check live Ahrefs DR and store real dated observations. The chart uses only database snapshots created by actual checks.
Free account required
The page stays public and indexable, but tool interaction requires a free account so automated abuse cannot hammer the free endpoints.
Practical guide
A single DR check only tells you the current value. The tracker adds dated snapshots so you can see whether backlink work is producing a sustained change instead of reacting to one number.
The latest value comes from Ahrefs' public Domain Rating endpoint when the server key is configured.
If your Ahrefs plan permits the historical endpoint, the tool merges that history into the chart.
When historical API data is unavailable, signed-in users can still build a browser-side series from repeated checks over time.
Ahrefs historical Domain Rating data can depend on API-plan access. The tool still saves your own dated checks locally so the graph grows over time.
Weekly or monthly is usually enough for trend monitoring. Backlink indexes and authority metrics do not need minute-by-minute checking.
