The Free SEO Authority
Checker Built for Everyone
CheckSEORank is an SEO metrics platform that gives you instant access to Domain Authority, Page Authority, Spam Score, Backlinks, and Keyword Difficulty — all powered by the Moz API.
Our Story: From Frustration to Freedom
CheckSEORank didn't start in a boardroom. it started in a messy home office in early 2026. As independent SEO consultants, we were tired of being locked out of the data we needed to compete.
Top-tier platforms like Ahrefs and Moz charge hundreds of dollars per month. For a new blogger or a small local business, that's not just a cost — it's a barrier to entry. We saw thousands of talented marketers struggling because they couldn't simply check their domain authority without a credit card.
So, we built the tool we wanted to use. We secured a partnership with Moz API to bring professional-grade metrics (DA, PA, Spam Score) to everyone. No hidden fees, no "contact sales" buttons, just the data you need to grow.
Why the name CheckSEORank?
"We wanted a name that was a promise. You come here to check your SEO rank, your authority, and your competition. We handle the complexity; you handle the strategy."

Understanding Domain Authority, DR, and SEO Metrics
Domain Authority (DA) is a metric developed by Moz that predicts how well a website will rank on search engine result pages. Scores range from 1–100, with higher scores indicating stronger ranking potential. It's calculated using MozRank, MozTrust, the number of linking domains, and spam signals.
Domain Rating (DR) from Ahrefs is a similar metric but uses a different algorithm focused purely on the strength and quantity of referring domains. Many SEOs debate whether Moz DA vs Ahrefs DR is more accurate. CheckSEORank now supports both metrics, giving you access to both Moz DA and Ahrefs DR in one unified analysis.
For developer workflows and bulk audits, our new **Developer API** exposes all of these endpoints (including Moz authority metrics and Ahrefs Domain Rating) as clean, standard REST JSON resources, allowing you to feed your custom SEO dashboards seamlessly.
When you check domain authority for your site or competitors, you're building a foundation for smarter link building, content strategy, and outreach. A high DA and high DR site will generally rank for more competitive keywords and command higher authority signals.
Our platform also includes a website spam score checker, helping you identify risky backlinks in your profile before they cause ranking drops. This is essential for any SEO website checker workflow, especially after Google algorithm updates.
