What's the Deal With Domain Authority?
You've probably heard it thrown around in link building conversations. "That site has great domain authority." "We're targeting DA 40+." "Higher authority links are worth more." But here's the thing — it's not as straightforward as the number suggests.
Domain Authority (DA) is Moz's proprietary metric that predicts how well a domain will rank on search engines. It's a number from 1 to 100, and sure, higher generally means better. But it doesn't work the way many people think it does. We've seen plenty of low-DA sites rank for competitive keywords, and plenty of high-DA sites that don't rank worth a damn for their niche.
The real story is more nuanced. What actually matters isn't the DA score itself — it's what that score represents underneath.
The Core Truth
Domain Authority is a prediction tool based on link profile strength. It doesn't rank sites directly — Google does. Understanding the difference is everything.
What Actually Moves Domain Authority
DA changes when your backlink profile changes. That's it. New links, lost links, changes in the quality of linking domains — these shift the metric. But not all links hit equally.
Link Quality Over Quantity
One link from a domain with DA 60 does more for your authority than ten links from DA 20 sites. It's not about the number of backlinks — it's about the strength of the domains linking to you. That's why we focus on targeted outreach to relevant, established sites rather than bulk link schemes.
Relevance and Context Matter
A link from a site in your industry carries more weight than a random high-DA site. Google's algorithm has gotten smarter about context. A real estate site linking to you from an actual real estate publication hits different than a finance site forcing in an irrelevant mention.
Anchor Text Signals
How the link is labeled matters. Natural anchor text (your brand name, partial phrases) looks better than exact-match keywords. You're aiming for links that look like actual editorial mentions, not SEO tactics.
How DA Gets Calculated (and Why You Shouldn't Obsess Over It)
Moz calculates DA by analyzing your entire backlink profile — domains linking to you, their authority scores, the anchor text used, the page authority of the linking pages. It's a composite score that updates monthly.
Here's where people get it wrong: they chase the number. "We need to get to DA 50." But if you're building links strategically and naturally, DA follows. It's a lagging indicator, not a leading one. You don't build links to improve DA — you build links to improve rankings and traffic. DA improvement is the byproduct.
We've worked with Calgary businesses that've seen their DA grow from 15 to 35 in about 8 months, not by targeting DA specifically, but by getting high-quality, relevant links from local media, industry directories, and partner sites. The number moved because the link profile got stronger.
Where to Focus Your Actual Effort
Stop checking DA scores daily. Here's what actually moves the needle:
1
Target Relevant Sites in Your Space
Look for sites that serve your audience. Local business publications, industry directories, niche blogs. A link from a Calgary-focused business magazine matters more than a random DA 50 site about unrelated topics.
2
Build Relationships, Not Just Links
Outreach that feels personalized gets better results. Journalists and editors can tell the difference between a template email and one that actually references their recent work. That's how you get links that stick and feel natural.
3
Focus on Linking Page Quality Too
Don't just check the domain's DA. Look at the specific page where your link will live. A link from a high-traffic, well-linked page on a relevant site beats a link buried deep on a low-traffic page, even if the domain looks good.
4
Monitor, But Don't Obsess
Check your DA monthly, not weekly. Watch your rankings and organic traffic instead — those are the real metrics that matter. If you're getting quality links and your traffic's climbing, the DA will follow.
The Bottom Line
Domain Authority is a useful metric, but it's not the goal — it's a scorecard. You're not building links to increase a number on Moz's chart. You're building links because relevant, authoritative sites in your space are recommending you to their audiences. That drives traffic. That builds credibility. That's what actually grows your business.
When you focus on strategic, relationship-based outreach to sites that matter in your industry, your DA grows naturally. You don't need to chase it. And honestly, that's when you know you're doing link building right.

While backlink quality and relevance are important for SEO, actual search rankings are determined by Google's algorithm, which considers many factors beyond domain authority.
