Check Domain and Page Authority: A Complete Guide for Smarter SEO

In the ever-changing world of digital marketing and search engine optimization (SEO), knowing where your website stands is more important than ever. With countless businesses and creators competing for the top spot on Google, every bit of insight helps. One of the easiest and most effective ways to understand your site’s strength is to check domain and page authority. These two metrics can tell you a lot about your site’s credibility, SEO health, and its ability to compete in search engine rankings.

Whether you’re a blogger, digital marketer, startup founder, or small business owner, understanding Domain Authority (DA) and Page Authority (PA) gives you a clear roadmap for your online growth strategy. But what do these terms really mean? Why are they important? And how can you check them easily?

Let’s break it down step-by-step in a way that’s practical, beginner-friendly, and useful for anyone looking to build an impactful online presence.


What Is Domain Authority?

Domain Authority (DA) is a search engine ranking score developed by Moz. It ranges from 1 to 100 and predicts how well a website will rank on search engine result pages (SERPs). The higher the score, the stronger the site’s authority in the eyes of search engines like Google.

This score is calculated using a combination of factors, including:

  • Total number of backlinks

  • Quality of linking domains

  • Internal linking structure

  • Site age and content consistency

  • Technical SEO elements

It's important to remember that DA is not an official Google ranking factor, but it serves as a valuable indicator of your website’s overall authority compared to others in your niche.


What Is Page Authority?

Page Authority (PA), also created by Moz, measures the strength of an individual page rather than the whole domain. Like DA, it’s scored from 1 to 100. While DA reflects your website's overall power, PA lets you zoom in on a specific blog post, landing page, or product page to evaluate its potential to rank.

This can help you understand which pieces of content are performing well — and which ones need more work to climb the search engine ladder.


Why Should You Check Domain and Page Authority?

Checking your DA and PA is more than just a numbers game — it’s about building a smart SEO plan based on real data. Here's why these metrics matter:

1. Understand Your Competitive Position

Let’s say you’re trying to rank for a keyword like “best hiking shoes.” If all the top-ranking pages have DA scores above 70 and yours is at 30, you’ll know it’s going to be an uphill battle. That insight helps you either refine your keyword targets or double down on authority-building strategies.

2. Measure SEO Progress

If you’re investing time in content marketing, link building, and technical SEO, you want to know if it’s working. Tracking your DA and PA over time gives you a clear view of whether you’re gaining authority.

3. Improve Link-Building Strategy

Links from high-DA websites are more valuable than those from low-authority sites. By checking DA and PA of potential backlink sources, you can focus your outreach efforts more effectively.

4. Prioritize Page-Level SEO

Knowing which pages have high or low PA helps you decide where to concentrate your optimization efforts. A low-PA page with high traffic potential could become a ranking powerhouse with a few smart updates.


How to Check Domain and Page Authority

Luckily, checking DA and PA is simple and doesn’t require advanced technical skills. A wide range of tools — both free and premium — allow you to enter a URL and instantly see its DA and PA scores. These tools often provide additional insights, like:

  • Number of backlinks

  • Referring domains

  • Spam score

  • Top-performing pages

All you need to do is enter your site’s URL, click “Check,” and you’ll receive a snapshot of its authority profile.

Pro tip: Check not only your own site but also competitor websites and potential backlink sources. This helps you create a well-rounded, strategic SEO plan.


What Is a Good DA or PA Score?

There’s no universal answer because it all depends on your industry and competition. However, here’s a general guideline:

  • 1–20: New or small websites

  • 21–40: Growing sites with basic SEO and link-building

  • 41–60: Solid authority and performance in mid-competition niches

  • 61–80: High authority, often established brands or strong content sites

  • 81–100: Elite-level sites (e.g., Wikipedia, Amazon)

What’s considered “good” for you depends on what your competitors are doing. If you’re in a local niche with low competition, a DA of 30 might be enough to dominate search results.


How to Increase Your Domain and Page Authority

While DA and PA can’t be improved overnight, consistent SEO efforts can absolutely push those numbers up over time. Here are the best ways to do it:

1. Create High-Quality Content

Strong content attracts natural backlinks, keeps users engaged, and builds topical authority. Focus on solving problems, answering questions, and providing unique insights.

2. Earn Backlinks from Authoritative Sites

Reach out for guest posting, content collaborations, and media features. Aim to get links from sites with higher DA than your own — this helps transfer authority to your domain.

3. Optimize Your Site Structure

A clean, intuitive site structure helps search engines crawl and index your pages efficiently. Use internal linking to pass authority between pages and improve PA scores.

4. Fix Technical SEO Issues

Ensure your website is mobile-friendly, fast-loading, secure (HTTPS), and free of broken links. These factors don’t just improve user experience; they also impact your authority.

5. Disavow Toxic Backlinks

Low-quality or spammy backlinks can damage your authority. Regularly audit your backlink profile and disavow harmful links to maintain trustworthiness.


When Should You Check DA and PA?

While checking authority metrics daily isn’t necessary, here are the best times to review them:

  • Before a link-building campaign (to identify strong backlink sources)

  • After publishing new content (to track how a page’s PA develops)

  • Monthly SEO reviews (to monitor domain-level improvements)

  • Competitor audits (to benchmark your position)

This ensures you're always working with the latest, most useful data.


Misconceptions About Domain and Page Authority

Let’s clear up some common misunderstandings:

  • DA and PA are not official Google metrics. They’re created by Moz and used as third-party indicators of ranking potential.

  • More links don’t always mean higher authority. Quality matters more than quantity.

  • You can’t instantly “boost” DA. It’s the result of long-term SEO success, not shortcuts.


Conclusion

To truly grow your digital footprint, it’s essential to check the domain authority and page authority of your website regularly. These metrics help you understand where you stand in your niche, what areas need improvement, and how to make smarter SEO decisions moving forward.
