About the Domain Authority Checker
“Domain Authority” is Moz’s proprietary metric and can’t be fetched for free. Instead, the Toolcenter Domain Authority Checker gives an independent on-page and technical health score from 0–100, based on 16 signals it can measure directly: HTTPS, response speed, page weight, title and description, Open Graph, structured data, canonical, robots.txt, sitemap reference, internal linking, compression, caching and mobile viewport.
How to use it
- 1Enter a domain or URL.
- 2Run the analysis (it fetches the homepage and robots.txt).
- 3Read the 0–100 health score.
- 4Work through the failed signals to improve it.
Key features
- 16 weighted on-page and technical signals
- 0–100 health score with a gauge
- Pass/fail list with specifics
- Checks robots.txt and sitemap reference
- Server-side fetch, no paid API
Frequently asked questions
Is this the real Moz Domain Authority?+
No. DA is proprietary and needs Moz’s paid API. This is an independent technical-health estimate you can act on directly.
What does the score measure?+
How well the page follows on-page SEO and technical best practices — not backlinks or ranking history.
How can I raise the score?+
Fix each failed signal: add HTTPS, a meta description, Open Graph tags, structured data, a sitemap reference in robots.txt, and improve speed and internal linking.
Is the site data stored?+
No. The homepage and robots.txt are fetched once to compute the score.
