Domain Authority (DA) and Page Authority (PA) are the most widely used metrics for predicting how well a website will rank on search engines. Whether you're evaluating a link-building opportunity, analyzing competitors, or tracking your own site's growth — knowing your DA/PA score is essential.
The DA/PA Checker by Jayax.dev lets you check the authority score of any website or page — instantly and for free.
Understanding Domain Authority and Page Authority
What Is Domain Authority (DA)?
Domain Authority is a predictive metric (0-100 scale) that estimates how likely a domain is to rank in search engine results. Developed by Moz, it aggregates multiple factors including:
- Linking root domains — number of unique sites linking to you
- Total backlinks — total number of inbound links
- Link quality — authority of linking sites
- Link diversity — variety of linking sources
- Site age and trust — how long the domain has existed
What Is Page Authority (PA)?
Page Authority measures the ranking strength of a single page rather than the entire domain. A specific blog post might have a higher PA than the domain's overall DA if it has attracted many high-quality backlinks.
DA/PA Score Ranges
| Score | Rating | What It Means | |-------|--------|---------------| | 0-20 | Low | New or low-authority sites. Needs significant link building. | | 21-40 | Below Average | Growing sites. Can rank for low-competition keywords. | | 41-60 | Average | Established sites. Competitive for medium-difficulty keywords. | | 61-80 | Good | Strong authority. Can compete for most keywords. | | 81-100 | Excellent | Top-tier authority. Major publications and brands. |
DA vs. PA: When to Use Each
| Use Case | Metric to Check | |----------|----------------| | Overall site strength | Domain Authority | | Specific page ranking potential | Page Authority | | Link-building target evaluation | DA of target site | | Content ranking potential | PA of your page | | Competitor comparison | Both DA and PA | | Guest post opportunity | DA of host site |

FAQ — DA/PA Checker
Is DA a Google ranking factor?
No. Domain Authority is a third-party metric created by Moz. Google does not use DA in its algorithm. However, DA correlates strongly with actual ranking performance because it measures the same factors Google considers (link quality, diversity, etc.).
How often does DA update?
DA scores are updated periodically as the link index refreshes. Significant changes in your backlink profile may take weeks to reflect in your DA score.
Can DA go down?
Yes. DA can decrease if:
- You lose high-quality backlinks
- Your competitors gain more authority
- You accumulate toxic or spammy links
- The overall index is recalibrated
What's a good DA for a small business?
For most small businesses, DA 20-40 is realistic and sufficient to rank for local and niche keywords. Focus on quality over quantity — a DA30 site with great content can outrank a DA50 site with thin content.
How does this compare to Moz's DA checker?
Our tool provides similar authority metrics based on link data analysis. For the most comprehensive data, you can cross-reference with Moz's Link Explorer (limited free queries available).
