How to Audit Domain Authority with Moz (2026 Guide)

Domain Authority is Moz’s 1 to 100 score that predicts how well a site will rank on Google. It is not a Google metric (Google itself uses PageRank internally which is different), but DA remains the industry standard proxy that Filipino agencies and clients understand. A healthy DA trend is one of the clearest signals that your SEO work is compounding.

This guide walks you through a full DA audit in Moz Pro: how to read the current score, spot toxic drops before they hurt rankings, benchmark against competitors, and build a plan to grow DA steadily over the next 12 months.

What Domain Authority actually is (and is not)

Before auditing, get the definition right:

• DA is a 1 to 100 score calculated by Moz based on the strength of your backlink profile plus 40+ other signals
• It is a comparative metric (a DA 30 site is stronger than DA 20, weaker than DA 50)
• DA correlates with Google ranking ability but does not cause it (Google does not use Moz DA in their algorithm)
• DA is logarithmic, moving from DA 20 to 30 is much easier than moving from DA 50 to 60
• DA can drop suddenly when Moz updates their algorithm (roughly every 6 months)

Step 1: Open your DA dashboard in Moz Pro

1. Log in to Moz Pro at analytics.moz.com
2. Select your campaign (or create one if you have not set up your site yet)
3. Click Overview in the left sidebar
4. You will see your current DA prominently at the top of the dashboard

If you do not have a Moz Pro campaign yet, click Add a Campaign, enter your domain, and give Moz 24 to 48 hours to crawl your site and generate the initial DA score.

Step 2: Read the DA trend chart

Under the current DA number, Moz shows a trend chart going back up to 24 months. This is the most important view in the entire audit.

• Steady upward trend: Your SEO work is compounding. Keep doing what you are doing.
• Flat line for 3+ months: Your link acquisition has stalled. Time to double down on outreach.
• Sudden drop of 5+ points: Either Moz did an algorithm update (check moz.com/blog for announcements) or you lost a batch of high-authority links.
• Sawtooth pattern: Normal DA volatility, do not overreact to week-to-week changes.

Take a screenshot of your 12-month DA trend at the start of every quarter. Compare quarter over quarter to see real progress.

Step 3: Check DA vs Linking Domains growth together

DA alone is not enough. Cross-reference against your Linking Domains growth to spot problems early:

1. Click Link Analysis in the left sidebar
2. Toggle the chart to show both Domain Authority and Linking Domains
3. Look for these patterns:
   • Both rising together = healthy growth
   • Linking Domains rising but DA flat = new links are low quality (or Moz has not scored them yet)
   • DA rising but Linking Domains flat = other signals improving (page authority, spam score reduction, etc.)
   • Both dropping = urgent problem, investigate immediately

Step 4: Investigate any DA drop

If your DA dropped 5+ points in a single Moz update:

1. Check the Moz blog for any recent algorithm changes (moz.com/blog). If Moz did a scoring update, drops across many sites are normal and not your fault.
2. Go to Inbound Links, sort by Discovery Date descending, look for lost links in the past 30-60 days
3. Cross-reference lost links against high-Domain-Authority sources. Losing a DA-70 link matters much more than losing 10 DA-15 links.
4. Check your own site’s Spam Score in Moz. If it rose to 5+, you may have accumulated toxic links needing disavow.
5. Compare against competitors in your niche. If everyone dropped simultaneously, it is a Moz-side algorithm update, not your specific problem.

Step 5: Benchmark against 3-5 direct competitors

Absolute DA numbers matter less than relative position in your niche. Set up competitor tracking:

1. In Moz Pro, click Compare in the Link Analysis section
2. Enter 3 to 5 direct competitor domains
3. Compare their DA, Linking Domains, and Spam Score against yours
4. If a competitor has DA 40 and you have DA 25, they have roughly 4-5x your organic ranking power
5. Prioritize backlink outreach to the same sources they use (via Link Intersect, covered in our backlink audit tutorial)

Step 6: Build a 12-month DA growth plan

Realistic DA growth for a small or mid-size site:

• DA 1-10 (brand new site): Target DA 15-20 within 6 months by publishing 30+ quality articles and pursuing 20-40 relevant backlinks
• DA 20-30 (growing site): Target DA 30-40 within 12 months by scaling outreach and adding pillar content
• DA 30-45 (established niche site): Target 5-10 DA points per year through digital PR and thought leadership
• DA 45+ (authority site): Focus on protecting existing DA and expanding into adjacent verticals; further growth becomes much slower

Every DA point above 30 requires roughly 2x the effort of the previous point. This is why chasing DA 90 is unrealistic for most sites; DA 40-50 is where most successful independent sites plateau naturally.

Common DA audit mistakes

• Obsessing over weekly changes. DA fluctuates 1-3 points naturally. Only worry about 5+ point moves over 30+ days.
• Comparing your DA to Wikipedia’s. Wikipedia is DA 95. Comparing yourself to that gives you no signal. Compare to direct niche competitors.
• Buying links to inflate DA. Google penalizes bought links. Moz also detects link networks and flags Spam Score up.
• Ignoring the trend chart. Absolute DA today is less important than the 12-month trajectory.
• Not documenting audits. Screenshot key metrics quarterly so you have concrete comparison data.
