DA PA & DR Checker
Compare third-party authority metrics like DA, PA, and DR for a domain.
What this tool does
This tool estimates authority metrics for a domain or URL, including DA, PA, DR, backlinks, and spam indicators. These are third-party SEO metrics that help compare relative strength and link profile quality. Use them for benchmarking and trend tracking, not as official ranking scores.
Inputs explained
- Domain or URL: The domain or specific page you want to evaluate.
How it works / Method
The tool queries authority metrics from external providers and displays the reported scores. If an API is unavailable, demo values may be shown to illustrate the format. Results depend on the provider's link index and scoring model.
| Domain | |
|---|---|
| Spam Score |
Example
Input: Domain: example.com. Expected output: DA, PA, and DR values on a 0-100 scale, a backlinks count, and a Spam Score indicator. If demo mode is active, the tool will show a badge indicating simulated values.
Use cases
- Benchmark competitors or prospects in outreach campaigns.
- Track link profile growth over time.
- Screen domains for potential spam risk.
- Prioritize outreach targets for SEO.
- Compare domain strength across portfolios.
Limitations & notes
- Metrics are proprietary and vary across providers.
- Scores are directional and not official search engine rankings.
- Backlink counts depend on each provider's crawl coverage.
- Demo values may appear if the live API is unavailable.
Accuracy & Disclaimer
Authority metrics are estimates from third-party providers and should be used for comparison only. For critical decisions, review multiple data sources and the underlying link profile.
Frequently Asked Questions
What are DA, PA, and DR?
DA (Domain Authority) and PA (Page Authority) are Moz metrics that estimate ranking potential based on link data, while DR (Domain Rating) is an Ahrefs metric that measures backlink profile strength. Each uses its own link index and scoring model, so values are not interchangeable. These metrics are best used for comparison and trend analysis rather than absolute judgments of quality.
Are these scores official search engine rankings?
No. DA, PA, and DR are third-party metrics created by SEO tool providers, not official search engine scores. They can be helpful for relative comparisons or tracking improvements over time, but they do not represent how a search engine ranks a page. Use them alongside other signals like content quality, relevance, and technical health. When making decisions, compare multiple sources and review actual search performance data if available.
Why do scores differ between providers?
Providers crawl the web differently and maintain separate link indexes, so they see different backlink sets. Each provider also applies its own scoring formula, which can weigh links, domain diversity, and quality differently. As a result, DA, PA, and DR can vary even for the same domain. Trends over time within a single provider are usually more meaningful than cross-provider comparisons.
What is Spam Score?
Spam Score is a Moz metric that estimates how similar a site is to known spam patterns based on a set of signals. It is not a penalty and does not come from search engines. A higher score suggests higher risk, but it should be interpreted in context with content quality and link patterns. Use it as a flag for closer review rather than a final verdict.
What does the backlinks count represent?
Backlinks shown here reflect the links discovered by the underlying provider, not the complete set of links on the web. Different tools will report different counts based on crawl coverage and update frequency. A backlink count is most useful when tracking direction over time or comparing domains within the same tool, rather than treating it as a definitive total. Providers may also filter duplicates or low-quality links, which can change totals.
Why do I see simulated or demo results?
If the upstream metrics API is unavailable, rate-limited, or configured for demo mode, the tool may display simulated values to demonstrate the layout. A badge will indicate when results are simulated. For production accuracy, ensure the API integration is enabled and returning live data. Check API credentials and request limits if results remain simulated. Always treat demo values as placeholders rather than real metrics.
