What is a domain authority checker?
Domain Authority, or DA, is a score created by Moz. It runs from 1 to 100 and is meant to predict how likely a site is to rank in search results compared with others. Moz calculates it from link data, mainly. It is not a Google metric, and Google does not use it.
Here is the honest part about this page. Under the box labelled Enter Domains (one per line), the Check SEO Metrics button builds a table with columns for DA, PA, Spam %, Backlinks, Ref Domains, Age, Traffic and Keywords. Every one of those values is random. The code generates a new number each time, and it never looks up your domains anywhere. Enter the same domain twice and you will get two different answers.
So treat the table as a layout demo. The Export CSV and Copy buttons work, but they save the random numbers. For real figures, use the checker from Moz itself, or another link index such as Ahrefs or Semrush, and remember that each reports its own metric. None of them is a ranking factor.
How this demo table works
- Type or paste domains into Enter Domains (one per line), for example example.com.
- Click Check SEO Metrics. The button briefly changes to Checking.
- Read the table, but remember every number in it, from DA to Keywords, is randomly generated.
- Use Export CSV or Copy if you want the sample table as a file or text.
- Click Clear to empty the box and hide the export buttons.
- Take the domains to a real link-analysis service to get actual Domain Authority or similar figures.
What the page actually does
Multi-domain table
Each line you enter becomes a row. Text is not validated, so any line works, even if it is not a real domain.
Random sample values
DA and PA are random whole numbers up to 99, Spam is up to 29 and backlinks up to 99,999, with no relation to the real site.
No data source
The page makes no request to Moz, Google or any other provider, so nothing in the table is measured.
Export CSV
Downloads the sample table as seo-results.csv. It contains the same random numbers.
Copy
Copies each domain and its DA value as plain lines.
Dark mode toggle
The moon button switches the page between light and dark styling.
When this page is, and is not, useful
- Anyone wanting real DA. This page will not give it. Use Moz Link Explorer, which offers limited free checks, and treat the result as one rough signal.
- Designers and writers. You can use the table as a placeholder to see what an SEO report layout looks like, as long as no one mistakes it for data.
- Link buyers and sellers. Do not use the numbers to price links. They are made up.
- Site owners improving rankings. Check titles and snippets with the SERP Preview Tool and audit your tags with the Meta Tag Analyzer instead.
Tips for checking real domain authority
- Never publish or share figures from this page as if they were measurements.
- Compare sites using one provider's metric only. Moz DA, Ahrefs DR and Semrush Authority Score are not interchangeable.
- Use authority metrics for comparison between similar sites, not as a goal. Google does not use DA to rank pages.
- Look at actual traffic, rankings and relevance of a site before judging it.
- For your own site, better content and genuine links matter more than the score.
- If you test this tool twice with the same domain and see different numbers, that is the sign that they are random.
Is it safe? Privacy and limits
The domains you type are handled in your browser and are not sent to any server, because the page makes no lookup at all. Nothing is stored. That also means no real data is retrieved. The numbers shown are random, so this page offers no SEO advice and should not be used for purchasing, valuation or reporting. Use a real link-analysis service for that.
Domain authority checker FAQ
No. The numbers on this page are randomly generated in your browser. The page does not contact Moz or any other data source, so it cannot know the real authority of any domain. Enter the same domain twice and you will see different values, which shows that they are placeholders. If you need a real score, use Moz's own tool, or compare with another provider such as Ahrefs or Semrush.
Domain Authority is a score from 1 to 100 developed by Moz that estimates how well a website might rank in search results. It is based on link data, such as the number and quality of linking domains, and uses a logarithmic scale, so moving from 20 to 30 is easier than from 70 to 80. It is a comparison tool for sites in the same niche, not a measurement that Google uses.
No. Google has said it does not use Domain Authority or similar third-party scores for ranking. DA is Moz's own prediction. A high score may correlate with strong links, but it does not cause rankings. Page quality, relevance, links and many other signals matter. Treat any authority score as a rough benchmark for comparing sites, never as a target, and never as proof of how Google sees a site.
Domain Authority rates a whole domain, and Page Authority rates one specific URL. Both are Moz metrics on a 1 to 100 scale. A strong domain can have a weak individual page, and a page with many links can outrank its domain's average. In this page's table both columns exist, but both are random, so they carry no information about the real site or page.
Use Moz Link Explorer, which offers a limited number of free lookups with an account, or look at similar metrics from other providers: Ahrefs Domain Rating, Semrush Authority Score and so on. Each uses its own link index, so numbers differ. Pick one provider and use it consistently when comparing sites. For information straight from Google about your own site, use Search Console.
They work on whatever is in the table, and the table holds random values. Export CSV saves the rows as seo-results.csv and Copy copies each domain with its DA. They are useful only for seeing how an export would look. Do not use the exported file for audits, reports or client work, because the numbers do not describe the real sites.
No. The domains you enter are used only within the page in your browser to build the table. Nothing is uploaded or saved, and no external lookup is made. That is also why the results are meaningless: the tool has no data source. Closing or reloading the page clears everything. If you use a real checker, read its privacy policy, since those services may keep a record of the domains you query.
Focus on things you can check and control: useful content, clear titles and descriptions, correct tags and a crawlable site. Preview your listing with the SERP Preview Tool, inspect your tags with the Meta Tag Analyzer, and look at your pages' headings and wording. Backlinks do matter, but earning them from relevant sites is more useful than chasing a single score.
