When analyzing a website’s authority or evaluating backlink opportunities, Domain Authority (DA) and Page Authority (PA) are still two of the most commonly referenced metrics in SEO.
While they are not Google ranking factors, they remain extremely useful for:
- Comparing websites at scale
- Vetting guest post and outreach opportunities
- Quick competitive analysis
- Filtering low-quality or spammy domains
The real challenge, however, is finding a reliable DA & PA checker that doesn’t lock results behind sign-ups, captchas, or daily limits.
What Are DA and PA (Quick Recap)
- Domain Authority (DA): Predicts how likely an entire domain is to rank in search engines.
- Page Authority (PA): Predicts the ranking strength of a specific URL.
Both metrics are developed by Moz and are calculated using link data, machine learning models, and multiple SEO signals.
Because DA and PA are Moz-owned metrics, the only truly accurate source is Moz’s own data.
The Problem With Most “Free” DA & PA Tools
Many tools claim to be free, but in practice:
- Require mandatory login or email verification
- Enforce captchas on every check
- Limit daily or monthly usage
- Show delayed or sampled data
This makes quick audits and outreach workflows unnecessarily slow.

When DA & PA Still Make Sense to Use

- Supporting decisions alongside traffic, relevance, and link quality
The key is consistency—use DA/PA as relative comparison metrics, not absolute ranking predictors.
