The Domain Authority Checker is a powerful free SEO tool designed to instantly evaluate your website’s authority, ranking strength, and backlink quality. Whether you’re a blogger, business owner, or digital marketer, knowing your site’s Domain Authority (DA) and Page Authority (PA) helps you measure SEO performance and improve visibility on Google.
With accurate DA and PA metrics, you can analyze competitors, identify link-building opportunities, and enhance your website’s credibility. This tool provides fast, reliable insights into your domain’s trustworthiness — making it essential for anyone aiming to rank higher in search engine results and boost organic traffic.
What is Domain Authority (DA)?
Domain Authority (DA) is a crucial SEO metric developed by Moz that predicts how well a website is likely to rank in search engine results. It is scored between 1 and 100 — the higher the score, the stronger your site’s authority. A website with a DA of 80+ is considered highly authoritative, while a new site may start around 10 to 20.
Domain Authority considers several factors, such as linking root domains, total backlinks, domain age, and overall site trust. It gives SEO professionals a clear idea of a website’s ranking strength and competitiveness in search engines like Google and Bing.
Why Domain Authority Matters in SEO
Search engines aim to deliver trustworthy and high-quality results. Websites with higher Domain Authority are usually more reliable and attract stronger organic rankings. While DA is not a direct Google ranking factor, it correlates strongly with SEO performance. Here’s why it matters:
- Helps Measure SEO Performance: DA allows you to track your site’s progress as you implement SEO strategies.
- Identifies Competitors’ Strength: By checking competitors’ DA, you can set realistic goals and target keywords more strategically.
- Improves Link-Building Strategy: High-DA sites provide better-quality backlinks that boost your own authority.
- Determines Site Trustworthiness: Websites with high DA are considered more trustworthy and often attract higher click-through rates.
How Domain Authority is Calculated
Moz uses a complex algorithm to calculate Domain Authority. It takes into account over 40 ranking signals including:
- Number and quality of backlinks
- Root domains linking to your site
- Spam score
- Domain age and consistency
- Website content relevance and engagement
These elements are processed using a machine learning model that predicts the site’s ranking potential. Remember, DA scores are relative — improving from 20 to 30 is easier than jumping from 70 to 80.
What is Page Authority (PA)?
Page Authority (PA) measures the ranking power of individual web pages rather than the whole domain. A page with high-quality backlinks and well-optimized content can have strong PA, even if the overall site DA is moderate.
For example, a blog post that attracts links from popular websites can achieve a PA of 60+, signaling strong ranking potential for its target keyword.

Importance of Backlinks in Domain Authority
Backlinks are the backbone of Domain Authority. A website with a diverse set of high-quality backlinks will naturally have a higher DA. Search engines view backlinks as “votes of confidence” — the more trustworthy sites link to you, the more credible your website appears.
However, not all backlinks are equal. One link from a high-authority website like Forbes or HubSpot can be more valuable than hundreds from low-quality directories. Always prioritize quality over quantity when building backlinks.
Common Mistakes to Avoid
- Buying backlinks from spammy sources.
- Over-optimizing anchor texts.
- Ignoring technical SEO errors such as broken links or slow pages.
- Publishing thin or duplicate content.
- Failing to update content regularly.
