Domain Authority Checker

Free Domain Authority Checker and Website Authority Checker

Use our free Domain Authority Checker to investigate the authority, backlinks, spam risk, popularity and technical background of any public website. Enter a domain above to receive a website authority report containing several independent SEO metrics and public domain records.

The checker can help you research your own website, compare competitors, assess a potential backlink opportunity or investigate a domain before buying it. The report includes authority scores, indexed backlinks, referring domains, spam indicators, website ranking data, domain age, registration information and hosting details.

No single score can describe the complete quality of a website. That is why this free website authority checker presents several signals rather than relying on one number.

How to Check Domain Authority for Free

To check domain authority, enter a domain name into the field above and select Check Domain. You can enter a standard domain, such as example.com, or a complete website address.

The checker collects the available metrics and organises them into a single report. Fresh results may be cached to make future checks faster and reduce unnecessary requests to external data providers.

When reviewing the report, compare the checked domain with websites of a similar size, subject and audience. Comparing a small local business with a major international publisher will not provide a meaningful benchmark.

For the most useful results:

• Check your own domain to establish a starting point.
• Check several genuine search competitors.
• Compare the same authority and backlink metrics.
• Look at referring domains as well as backlink totals.
• Review domain age, spam risk and website history.
• Repeat the check periodically to monitor changes.

What Is Domain Authority?

Domain authority is a general SEO concept used to describe the relative strength and credibility of a website. A domain with a strong backlink profile, useful content and an established online presence will often receive higher third-party authority scores.

However, Domain Authority is not a Google ranking metric. Google does not publish a score from 0 to 100 for every website. SEO platforms create their own authority metrics using their own crawlers, backlink indexes and calculations.

The scores in this report should be used for research and comparison. They do not guarantee that a website will rank above another website in Google.

A lower-authority domain can still outrank a stronger domain when its page is more relevant, more useful or better suited to the user’s search.

Free Domain Rating Checker

The authority section works as a free domain rating checker by displaying available third-party measurements of backlink strength.

Ahrefs Domain Rating, usually shortened to DR, estimates the relative strength of a website’s backlink profile on a scale from 0 to 100. A higher DR generally indicates links from a stronger and more varied selection of websites.

Domain Rating uses a logarithmic scale. Moving from DR 20 to DR 30 is not necessarily as difficult as moving from DR 70 to DR 80.

A high Domain Rating does not mean that every page on the website ranks well. Individual pages still need relevant content, helpful internal links, appropriate backlinks and sound technical SEO.

This checker may display available Ahrefs Domain Rating data, but it is not the official Ahrefs website authority checker. The result should be considered alongside the other metrics in the report.

Website Authority Score Checker

A website authority score checker helps you compare the relative strength of different domains. This report may include an independent authority estimate from Crawly and a score from OpenPageRank.

The Crawly Authority Score uses signals available within Crawly’s own index. It provides another way to compare related websites, but it is not a Google score.

OpenPageRank is a third-party measurement inspired by the principle that links can pass importance between pages and domains. OpenPageRank is usually displayed on a scale from 0 to 10.

These scores use different data and calculations. They should not be directly converted or treated as interchangeable.

A website could receive a strong result from one provider and a more moderate result from another. This normally happens because each provider has discovered and evaluated a different collection of links.

Spam Score Checker: Check Website Spam Risk

The report includes a spam score checker that helps identify signs of a potentially weak or unnatural website profile.

The displayed spam score is supplied by Crawly and is presented on a scale from 0 to 100. Lower scores indicate lower detected risk, while higher scores suggest that the domain deserves closer examination.

A spam score can be useful when:

• Reviewing an unfamiliar website.
• Assessing a potential backlink.
• Investigating a domain before buying it.
• Monitoring the health of your own link profile.
• Comparing several link-building opportunities.
• Checking whether a domain displays unusual patterns.

The score is an automated risk indicator. It is not proof that a website is unsafe, and it is not the same as a Google penalty or manual action.

A low score does not guarantee that a website is trustworthy. A high score does not automatically mean that the domain should be avoided. Always review the website’s content, backlink relevance, ownership history and real reputation.

What Is a Good Spam Score?

A lower spam score is generally preferable. However, there is no universal number that guarantees a domain is safe or high quality.

The score should be interpreted with the rest of the report. A website with a low spam score but no useful content, no genuine audience and an unrelated backlink profile may still be a poor link opportunity.

Likewise, an established website could receive a moderate risk score because an automated system has identified patterns that require human review.

Do not make an SEO, advertising or domain-purchasing decision using the spam score alone.

How to Reduce Website Spam Score

If your website receives a higher-than-expected spam score, begin with a complete review rather than trying to manipulate the displayed number.

Audit Your Backlink Profile

Review the websites linking to your domain. Look for large groups of irrelevant, automated or obviously manipulative links.

Not every unusual backlink is harmful. Established websites naturally attract links from scrapers, copied pages and low-quality directories. Concentrate on patterns you created, purchased or actively control.

Improve Content Quality

Remove or improve thin, duplicated, misleading or automatically generated pages that provide little value. Make sure each important page has a clear purpose and satisfies a genuine visitor need.

Review Outbound Links

Check for hacked links, expired affiliate destinations and unrelated commercial links. Use appropriate sponsored or nofollow attributes where required.

Secure the Website

Update WordPress, themes and plugins. Remove unused administrator accounts, scan for malware and investigate unexpected pages or redirects.

A compromised website can create spam pages and links without the owner realising it.

Build a More Natural Link Profile

Earn relevant links from genuine businesses, publications, professional organisations and useful industry resources. A varied collection of trustworthy referring domains can create a healthier overall profile.

Avoid Automated Link Schemes

Do not buy bulk backlink packages or use software that creates thousands of low-quality links. These tactics may temporarily change third-party metrics without building genuine website authority.

The objective should be to improve the real quality and reputation of the website, not simply to force a lower score.

Free Backlink Checker and Referring Domains Checker

The backlink section functions as a free backlink checker by showing the links and referring domains found within the available provider indexes.

Backlinks are links from external websites to the checked domain. Search engines can use relevant and trustworthy links as signals of discovery, reputation and topical importance.

Backlink quality normally matters more than achieving the highest possible total.

Indexed Backlinks

Indexed Backlinks is the number of links currently found for the domain within Crawly’s index. This is an estimate rather than a complete count of every backlink on the internet.

One domain might link to your website hundreds of times through repeated navigation, footer or template links. These links can increase the backlink total without providing hundreds of independent endorsements.

Referring Domains

Referring Domains counts the number of separate websites linking to the checked domain.

If one website links to a domain 500 times, it may contribute 500 backlinks but only one referring domain.

A healthy backlink profile will often contain links from a varied collection of relevant websites rather than relying heavily on one source. For this reason, referring domains can provide more useful context than the raw backlink count.

Authority-Weighted Referring Domains

The report may also display referring-domain information from OpenPageRank. This figure may be weighted according to authority and can differ from Crawly’s estimate.

Use the numbers as separate provider measurements rather than expecting them to match exactly.

Why Do Backlink Checkers Show Different Results?

Every backlink checker operates its own crawler and database. One provider may discover a link that another provider has not yet visited.

Backlink totals can also differ because providers handle the following items differently:

• Redirected pages.
• Links from subdomains.
• Repeated sitewide links.
• Canonical pages.
• Deleted or unavailable pages.
• Nofollow and sponsored links.
• Websites that block crawlers.
• Recently created backlinks.
• Links hidden behind scripts or login screens.

A lower backlink count does not necessarily mean the result is wrong. It means the provider has counted the links available in its own index.

For meaningful comparisons, check several related domains using the same data source and metrics.

Free Website Ranking Checker

The popularity section provides broad ranking information and can be used as a free website ranking checker for comparing the general prominence of domains.

It is important to distinguish global website ranking from Google keyword ranking.

The figures shown here do not tell you whether a page ranks first, tenth or fiftieth in Google for a particular search phrase. A dedicated keyword rank tracker is required for that type of analysis.

OpenPageRank Global Rank

OpenPageRank Global Rank places a domain within the wider OpenPageRank dataset. A smaller global rank generally represents a stronger position.

For example, a domain ranked 100,000 is placed above a domain ranked 1,000,000 within that dataset.

Tranco Rank

Tranco Rank is a research-oriented website popularity ranking. It combines information from several lists and uses methods intended to make the ranking more stable.

A lower Tranco number generally represents a more prominent domain.

Popularity and SEO authority are related, but they are not identical. A popular website may not rank for every relevant keyword. A specialist website can also perform very well for valuable niche searches while having a modest global popularity rank.

Free Domain Age Checker

The report includes a free domain age checker that estimates how long a domain has been registered.

Domain age can provide useful context when researching a website or assessing a domain purchase. An older registration may indicate a more established history, but age alone does not create authority.

A new website can earn strong rankings by publishing excellent content and attracting relevant links. An old domain can have very little authority if it has been inactive, repeatedly resold or used for low-quality content.

Always consider domain age alongside:

• Backlink history.
• Previous ownership.
• Historical content.
• Brand reputation.
• Registration continuity.
• Current website quality.
• Relevant authority signals.

Domain Registration Checker

The registration section provides publicly available information about the administration of a domain.

Registered Date

The Registered date is the available date on which the domain record began. Registry data can vary between domain extensions.

In some cases, the date may reflect a transfer or registry event rather than the complete historical origin of the domain.

Domain Expiry Date

The Expires date indicates when the current registration period is scheduled to end.

An approaching expiry date does not necessarily mean that the website will close or that the domain will become available. Many businesses use automatic renewal.

Domain owners should always confirm renewal information directly through their registrar account.

Domain Registrar

The Registrar is the company authorised to manage the domain registration. The registrar is not necessarily the website’s owner, developer or hosting provider.

A business can register its domain with one company while hosting the website with another.

Domain Nameservers

Nameservers direct DNS requests towards the service responsible for managing the domain’s DNS records.

They can sometimes indicate which DNS, security or hosting provider a website uses. However, a content delivery network or proxy may hide the original hosting provider.

Website Hosting Checker and IP Address Information

The hosting section acts as a basic website hosting checker by displaying network information associated with the domain.

Website IP Address

The IP Address is the network address returned for the checked domain when the report was generated.

Websites can use several addresses, rotate between servers or use a content delivery network. The displayed address may represent an edge server rather than the original web host.

Many unrelated websites can also share one IP address. A shared IP is not proof that the websites have the same owner.

Hosting Network or Organisation

Network / Organisation identifies the company or organisation associated with the IP address.

This might be a web host, cloud platform, internet service provider or content delivery network rather than the business operating the website.

Autonomous System Number

An Autonomous System Number, or ASN, identifies a network that manages groups of internet addresses under a consistent routing policy.

Websites using the same ASN are not necessarily connected. Large hosting providers can operate millions of unrelated websites on the same network.

Server Location Checker

Server Country is an estimate based on the returned IP address or network record. It may describe a data centre, proxy or content delivery network location rather than the location of the website owner.

Modern websites can serve visitors from several countries. Treat server location as technical context rather than a definitive business location or Google ranking factor.

How to Increase Domain Authority

If you want to learn how to increase domain authority, concentrate on improving the real value and reputation of the website. Do not focus only on changing a third-party number.

Publish Helpful and Original Content

Create pages that answer genuine questions more clearly or thoroughly than competing results. Original research, detailed guides, useful tools, case studies and expert analysis are more likely to attract natural backlinks.

Build Topical Authority

Cover important subjects within your area of expertise rather than publishing unrelated articles for every available keyword.

Connect related pages through useful internal links. This helps visitors and search engines understand the structure and specialist focus of the website.

Earn High-Quality Backlinks

Earn links from relevant and trustworthy websites. One meaningful editorial link can be more valuable than hundreds of automated directory or comment links.

Useful link-building methods can include:

• Digital PR and newsworthy research.
• Industry statistics and surveys.
• Expert commentary.
• Original tools and calculators.
• Detailed reference guides.
• Relevant professional associations.
• Genuine business partnerships.
• Reclaiming unlinked brand mentions.
• Replacing broken links with a useful resource.

Improve Internal Linking

Link related pages using clear and descriptive anchor text. Important pages should not be isolated or difficult to reach.

Internal links help distribute authority through the website and show which pages are most important.

Fix Technical SEO Problems

Make sure search engines can crawl and index the correct pages. Review broken links, redirect chains, duplicate pages, canonical tags, XML sitemaps and accidental noindex instructions.

Improve speed, mobile usability and website security. Technical SEO will not create authority on its own, but technical problems can prevent strong content from performing properly.

Maintain a Trustworthy Website

Provide accurate business information, clear contact details and transparent ownership. Keep important content updated and correct errors when they are discovered.

Trust and authority are built over time through consistent quality.

Remove Manipulative Practices

Stop participating in paid link networks, automated link exchanges or irrelevant guest-post schemes designed only to change authority scores.

If you control poor-quality links, request their removal where practical. Do not remove legitimate links simply because they come from smaller websites.

Monitor Progress Over Time

Authority scores and backlink indexes do not update instantly. Check your domain monthly or quarterly and look for long-term movement rather than daily fluctuations.

How Long Does It Take to Increase Domain Authority?

There is no fixed timescale. A new website may need several months to publish enough useful content, earn relevant backlinks and establish a recognisable reputation.

The time required depends on:

• The competitiveness of the market.
• The current authority of the domain.
• Content quality and publishing frequency.
• Existing backlink relationships.
• Technical condition of the website.
• Digital PR and promotion.
• How frequently providers update their indexes.

Large jumps are uncommon without significant changes to a backlink profile. Sustainable improvement usually develops gradually.

What Is a Good Domain Authority Score?

A good authority score depends on the subject and competition.

Do not compare a small local business with a global news website. Compare your score with genuine competitors that target similar customers and keywords.

If competing websites generally score between 20 and 35, a score of 30 may be competitive. In another market, the leading domains might all score above 70.

Relative comparison is more useful than chasing an arbitrary score.

Frequently Asked Questions About Domain Authority

Does Google Use Domain Authority?

Google does not publish or use a public Domain Authority score. Third-party SEO providers create authority metrics to help users compare domains and backlink profiles.

Is Domain Authority a Ranking Factor?

Third-party authority scores are not direct Google ranking factors. They can correlate with search performance because strong websites often have useful content and trustworthy backlinks.

Correlation does not mean that Google uses the displayed score.

Can a Low-Authority Website Rank in Google?

Yes. A relevant and useful page on a lower-authority website can outrank a less relevant page on a stronger domain.

Page quality, search intent, topical relevance, internal linking and page-level backlinks all matter.

Why Did My Domain Authority Drop?

A score can fall because links were removed, a provider changed its index, competing websites gained stronger links or the scoring method was updated.

A small movement does not necessarily indicate lost Google rankings or a penalty.

How Often Should I Check Domain Authority?

Monthly or quarterly checks are sufficient for many websites. More frequent checks may be useful during an active content marketing, digital PR or link-building campaign.

Can I Check a Competitor’s Domain Authority?

Yes. Enter any public competitor domain into the checker. Compare several competitors using the same metrics to understand the authority levels common within your market.

Is a High Domain Authority Always Better?

A higher score can indicate a stronger backlink profile, but it does not guarantee better content, more traffic or higher rankings.

Use the score alongside relevance, real traffic, content quality, backlink diversity and spam risk.

Is This a Moz Domain Authority Checker?

This tool does not reproduce Moz’s proprietary Domain Authority metric. It combines other available authority measurements and public data to provide a broader domain report.

Is This a Google Rank Checker?

No. Global website popularity ranks are not the same as Google keyword positions. Use a dedicated keyword ranking tool to monitor positions for individual search phrases.

Can I Check Website Spam Score for Free?

Yes. Enter a domain above to view the available spam-risk indicator as part of the free domain report.

Remember that a spam score is an automated estimate and should always be supported by a manual review.

Check Domain Authority, Backlinks and Spam Score

Enter a domain into the free Domain Authority Checker above to review its authority scores, Domain Rating, indexed backlinks, referring domains, spam risk, global website ranking, domain age, registration information and hosting details.
