Frequently Asked Questions
Is DA a Google ranking factor?
No, it is a third-party metric that estimates ranking strength. It is still useful for comparing websites and judging the strength of a backlink profile over time.
Where does the Domain Authority Checker get its data?
It queries public internet sources in real time, such as DNS servers, WHOIS records and IP registries. Results reflect what those services report at the moment you run the check.
Why might the result differ from another tool?
DNS changes can take time to spread across the internet, and some services cache older data. If a result looks outdated, wait a little and run the check again.
Is the Domain Authority Checker safe and private?
Yes. Everything travels over a secure HTTPS connection, and the data you enter is used only to show your result – it is never published or sold. You do not need an account, and the tool works the same way on phones, tablets and computers.
Is the Domain Authority Checker free to use?
Yes. The Domain Authority Checker on pdfseotools.com is free to use – no sign-up, no watermark and no hidden charges for everyday tasks.
Do I need to install software or create an account?
