Good to know
Is this tool free and do I need an account?
It is free to use without an account. Domain checks have request limits to protect public services. Results can be downloaded from this page.
Where is my input processed?
Checks run on our server and contact public DNS, registry, website or Ahrefs services as needed. Results can be cached; inputs are not added to your URL or account. Do not submit private addresses or secrets.
What should I check before using the result?
The operator must configure an Ahrefs APIv3 key. Successful readings may be reused for one hour. Results are backlink metrics, not traffic or rankings. A provider refusal is shown per domain.
