The Beginner’s Guide to Domain Authority and Google PageRank
If you’re building a website, blog, or online business, you've probably heard of Domain Authority (DA) and Google PageRank. These metrics influence how your site performs in search engine results, and ultimately, how much organic traffic—and revenue—you can generate.
But what do they really mean? How do they work? And how can you improve them?
Let’s break it all down in plain language.
What Is Domain Authority?
Domain Authority is a score developed by Moz that predicts how likely a website is to rank on search engines. It’s scored on a scale from 1 to 100, with higher scores indicating a greater ability to rank.
Important Notes:
-
It’s not a Google metric. It’s a third-party tool created by Moz.
-
DA is best used to compare your site against competitors—not as a standalone success metric.
How Domain Authority Is Calculated:
Moz considers several factors, including:
-
The number of linking root domains (how many unique websites link to you)
-
Link quality and relevance
-
Spam score
-
Moz’s own machine learning models
In short: The more high-quality, relevant backlinks your site has, the higher your Domain Authority will be.
What Is Google PageRank?
PageRank was Google’s original algorithm for ranking web pages in search results. Created by Larry Page (hence the name), it focused primarily on backlinks—specifically, how many links a page had and how authoritative those links were.
Key Concepts:
-
Not all links are equal. Links from high-quality sites pass more PageRank.
-
Internal linking within your own site also affects PageRank distribution.
Is PageRank Still Used?
Yes, but not in the same way. Google no longer updates or shares public PageRank scores. However, the principles of PageRank—like link authority, relevance, and structure—still play a role in Google’s core algorithm.
Domain Authority vs. PageRank: What’s the Difference?
| Feature | Domain Authority (Moz) | PageRank (Google) |
|---|---|---|
| Who developed it? | Moz | |
| Publicly updated? | Yes | No (discontinued publicly in 2016) |
| Score Range | 1–100 | 0–10 (historically) |
| Main Focus | Backlink profile strength | Link quality and distribution |
| Usage | Competitive analysis | No longer visible but still part of ranking algorithms |
Why These Metrics Matter for Your Blog or Business
While DA and PageRank themselves aren’t ranking factors in the strictest sense, they reflect the health of your backlink profile and how much authority your domain holds in the eyes of search engines.
Here’s why that’s important:
-
Higher DA = Better chance to rank for competitive keywords
-
Strong backlinks = More trust from Google
-
Better rankings = More traffic = More revenue
7 Ways to Improve Domain Authority (and Influence PageRank)
1. Create Link-Worthy Content

Guides, research studies, and data-rich posts are great backlink magnets.

Identify low-quality links pointing to your site and disavow them via Google Search Console.
5. Improve Internal Linking
-
Use keyword-rich anchor text to link between your own posts.
-
Helps distribute PageRank and improve crawlability.
6. Build Topical Authority
-
Cover a subject in depth across multiple related articles.

Create amazing content
-
Promote it strategically
-
Build meaningful backlinks over time
The result? You’ll naturally increase your Domain Authority, attract more organic traffic, and grow a sustainable source of online income.
