A Domain Authority Checker helps you review the authority and backlink-related metrics available for a website. ChanduSEOTool's Domain Authority Checker lets you enter a website URL and check its Domain Authority, linking domains and total links in one place.
This tool is useful when comparing websites, reviewing competitors or carrying out basic SEO research. The results can help you understand how one domain compares with another, but authority metrics should be treated as research indicators rather than guarantees of Google rankings.

What Is a Domain Authority Checker?
A Domain Authority Checker is an SEO research tool that provides authority-related information about a domain. Instead of manually reviewing different website signals, you can enter a website URL and view the available metrics returned by the tool.
ChanduSEOTool's checker currently displays:
- Domain Authority – the authority score returned for the checked domain.
- Linking Domains – the number of domains shown as linking to the website.
- Total Links – the total number of links returned for the checked website.
- URL – the website address that was analyzed.
These metrics can be useful for quick website comparisons, SEO research and competitor analysis.
How to Use the Domain Authority Checker
Using the tool is simple:
- Enter the full website URL you want to check.
- Click the Check button.
- Wait for the tool to process the domain.
- Review the result table.
- Compare the Domain Authority, linking domains and total links with other websites when needed.
You can also use the available Sample option to see how the tool works before checking another website.
For best results, enter a valid website URL such as:
https://example.com/
What Is Domain Authority?
Domain Authority is an SEO metric used to estimate the relative authority or strength of a domain. It is commonly used when comparing websites during SEO research.
A higher authority score can indicate that a website has stronger authority signals than another website according to the data and methodology used by the metric provider. However, the score should not be interpreted as a direct prediction of where a website will rank for a particular Google search.
Authority metrics are most useful when used comparatively. For example, you might compare:
- your website with a direct competitor
- two websites within the same niche
- different domains you are researching
- potential websites for outreach or partnership research
Rather than focusing on a single score alone, combine authority information with content quality, relevance, technical SEO and other available website data.
What Are Linking Domains?
A linking domain is a separate domain that contains one or more links pointing to another website.
For example, if several pages on one website link to your domain, that website may still count as one linking domain while contributing multiple individual links.
This is why Linking Domains and Total Links are not the same metric.
Linking-domain information can help you understand whether backlinks come from a small number of websites or are spread across multiple domains.
What Are Total Links?
Total Links represents the number of links returned for the analyzed website by the tool's data source.
A website can have many links from only a few domains. For this reason, total link count should not be evaluated by itself.
For example:
- Website A may have many links from one or two domains.
- Website B may have fewer total links but links from a larger number of separate domains.
These patterns provide different information, so it is useful to review both metrics together.
How to Understand the Results
After checking a domain, ChanduSEOTool displays the available metrics in a simple results table.
URL
This shows the website address that was submitted for analysis. Always confirm that you entered the correct domain before comparing results.
Domain Authority
This is the authority value returned for the domain. Use it primarily as a comparison metric rather than as a guaranteed ranking score.
Linking Domains
This shows the number of separate linking domains reported in the result.
Total Links
This shows the total number of links reported for the checked website.
When reviewing these figures, avoid assuming that a larger number automatically means a better website. Link relevance, quality, context and other SEO factors also matter.
How to Use the Tool for SEO Research
The Domain Authority Checker can support several types of SEO research.
Compare Your Website with Competitors
Check your domain and several direct competitors individually. Record the results and compare the authority, linking domains and total links.
This can give you a quick overview of how your domain compares with other websites operating in the same niche.
Research Websites Before Outreach
If you are researching websites for partnerships, mentions or outreach, authority metrics can provide one additional signal when reviewing a domain.
Do not select a website only because of its authority score. Also consider:
- topic relevance
- website quality
- content usefulness
- audience relevance
- website reputation
Track Changes Over Time
You can periodically check the same domain and record its available metrics. This may help you notice changes over time.
Keep in mind that metrics can change when the underlying data source or website link profile changes.
Research a New Niche
When studying a new market, checking several established domains can help you build a rough picture of the websites operating in that space.
Using Domain Authority for Competitor Analysis
Competitor analysis is one of the most practical uses of a Domain Authority Checker.
A simple process is:
- Choose three to five genuine competitors.
- Check each domain separately.
- Record Domain Authority.
- Record Linking Domains.
- Record Total Links.
- Compare the results.
If a competing website has stronger metrics, do not assume that copying its backlink strategy will automatically produce the same results. Instead, use the information as a starting point for deeper research.
You can then investigate questions such as:
- Does the competitor publish more useful content?
- Does it cover topics your site does not?
- Does it have stronger brand recognition?
- Are other websites naturally referencing its resources?
- Does it have useful tools, studies or guides that attract links?
This approach makes authority checking part of a wider SEO research process rather than treating one metric as the entire strategy.
Domain Authority vs Google Rankings
Domain Authority should not be confused with a Google ranking position.
A domain with a stronger authority metric is not guaranteed to outrank another website for every keyword. Search results can depend on many factors, including the relevance and usefulness of a specific page.
For example, a smaller website with a highly relevant and useful page may perform better for a particular query than a larger website whose page does not satisfy the same search intent.
Use authority metrics for comparison and research, not as a guarantee of search performance.
Domain Authority vs Page Authority
Domain-level authority and page-level authority are different concepts.
Domain Authority focuses on the overall domain, while page-level metrics focus on an individual page or URL.
If you need to examine page-level authority separately, you can also use ChanduSEOTool's related Page Authority Checker.
For broader comparison involving both domain and page metrics, you can also review the DA PA Checker.
Important Limitations of Authority Metrics
No authority checker can tell you everything about a website.
Keep these points in mind:
- Authority metrics are third-party or tool-provided SEO indicators, not direct Google ranking guarantees.
- Different data providers may return different values.
- Link databases may not contain every link on the web.
- Metrics can change as data is refreshed.
- A high authority score does not automatically mean every page on a domain is high quality.
- A lower score does not automatically mean a website cannot rank for relevant searches.
For better analysis, combine authority data with other information such as search visibility, content quality, relevance and technical SEO.
