CheckSEORank vs Ahrefs vs Moz: Which DA Checker is Best?
In the SEO community, the debate between Ahrefs DR vs Moz DA is constant. While Moz pioneered the "Domain Authority" term, Ahrefs introduced "Domain Rating." Both metrics aim to solve the same problem: quantifying the strength of a website's backlink profile.

What Do These SEO Metrics Actually Mean?
Domain Authority (DA)
DA is a logarithmic score from 0–100. It is much easier to grow your DA from 10 to 20 than it is to grow from 70 to 80. It represents the likelihood of ranking for competitive terms. High domain authority websites like Wikipedia or The New York Times sit in the 90s, while brand-new blogs start at 1.
Page Authority (PA)
While DA measures the whole domain, PA measures the ranking strength of a specific page. This is crucial for guest post evaluation. A DA 80 site might have a new article with PA 1. Link builders often prefer links to specific high-PA pages to maximize SEO juice.
MozRank & MozTrust
MozRank measures link popularity, whereas MozTrust measures link "honesty" — how closely you are linked to trusted seed domains like .gov or .edu sites. Both work together to form the foundation of your DA score.
Keyword Difficulty (KD)
If you want to outrank competitors, you need to match their DA and content quality. KD estimates how hard that will be. Our keyword difficulty checker helps you pick battles you can actually win.
5 Strategic Use Cases for a DA Checker
Link Building Prospecting
Use our bulk da checker to scan 50 potential outreach targets. Filter for sites with DA 30+ and low spam scores to ensure your authority backlinks actually pass value.
Competitor Analysis
Identify which competitors are gaining ground. If a competitor's DA increases while yours remains stagnant, they likely secured several high authority domains as referring sources.
Expired Domain Evaluation
Before buying an expired domain for a niche site, check its historical DA and backlink profile. A "ghost" DA resulting from link manipulation will often have a high website spam score.
Client Reporting
Show your clients real progress. While rankings fluctuate daily, Domain Authority is a stable monthly metric that proves your link-building strategy is building long-term equity.
How to Increase Your Domain Authority?
Increasing DA isn't an overnight task. It requires a holistic approach to SEO. Start with a full technical SEO audit, then focus on earning dofollow links from relevant industries. Avoid "link farms" and focus on producing original research that journalists want to cite.
