CheckSeoRank

CheckSeoRank is a free SEO metrics tool that provides instant Domain Authority (DA), Page Authority (PA), Spam Score, Backlinks, Ahrefs Domain Rating (DR), and Keyword Difficulty data without requiring an account for initial checks.

What is CheckSeoRank?

CheckSeoRank is a web-based search engine optimization tool that analyzes any domain or URL against Moz's link index and Ahrefs' domain rating database. It returns a set of authority scores — DA (1–100), PA (1–100), DR (1–100), Spam Score (0–100%), total backlinks (with dofollow/nofollow split), and keyword difficulty — all on a single results page. The platform is developed and maintained by CheckSeoRank and is available as a website and a free Chrome extension.

What makes CheckSeoRank stand out?

• Free initial checks — First search per visitor requires no signup or credit card; subsequent checks require a free account (10 searches/month).
• Real-time Moz API data — All Moz metrics (DA, PA, Spam Score) are queried live from Moz's Link Explorer, not cached.
• Ahrefs Domain Rating (DR) — In addition to Moz metrics, CheckSeoRank pulls live DR scores from Ahrefs' crawler, a feature not offered by most free tools.
• Bulk domain analysis — Pro and Agency plans allow checking up to 10+ domains simultaneously with CSV export for client reporting.
• Spam score detection — Moz's proprietary spam score (0–100%) flags potential penalty risks before link building.
• Backlink breakdown — Displays total backlinks, number of dofollow and nofollow links, and referring domains for any site.
• Keyword difficulty assessment — Estimates how competitive a keyword is on a 0–100 scale, helping prioritize content targets.
• Developer API — Pro ($29/mo) and Agency ($79/mo) plans include API access with up to 5,000 requests per month and a 60 requests per minute rate limit, returning JSON metrics for integration into custom dashboards or scripts.

Who is it for?

• SEO professionals and agencies — Use it to quickly audit client domains, check spam scores before outreach, and run bulk reports for proposals.
• Digital marketers — Analyze competitor authority and keyword difficulty to refine content strategy and link building campaigns.
• Website owners and bloggers — Monitor their own DA/DR progress over time and identify potential backlink opportunities.
• Domain investors — Evaluate the authority and spam score of domains before purchase or resale.

• Bulk check multiple domains — Pro and Agency subscribers can analyze up to 10+ domains at once and export results as CSV for client reporting.

FAQ

What is a good Domain Authority score?

DA scores range from 1 to 100. A score above 50 is generally considered good; 60–80 is excellent for competitive keywords. Compare your DA against direct competitors rather than absolute benchmarks.

What is the difference between Moz DA and Ahrefs DR?

Moz DA (Domain Authority) is a predictive score based on Moz's link index and spam signals. Ahrefs DR (Domain Rating) focuses on the number and quality of unique referring domains. They use different indexes and formulas, so the same domain often gets different scores from each tool.

How can I increase my Domain Authority?

Earn high-quality backlinks from authoritative sites, publish consistent original content, remove toxic links (high spam score), optimize internal linking, improve page speed, and fix technical SEO issues. CheckSeoRank's spam score and backlink breakdown can help identify problem areas.

Is CheckSeoRank free?

Yes, but with limits. One free search per visitor without an account. After that, you need a free account for 10 searches per month. Paid plans start at $9/month for more searches and API access.
