When you are building a new blog on Blogger, it’s easy to get obsessed with vanity metrics like page views. But in 2026, the metrics that actually matter for long-term SEO success are Domain Authority (DA) and Page Authority (PA).
Think of DA and PA as your blog’s credit score. If your score is low, Google won't trust you, and your posts will never reach Page 1. If your score is high, you can rank for difficult keywords almost instantly.
Here is the Blogger Master guide to understanding and conquering these critical metrics.
Domain Authority (DA): Your Blog’s Reputation
Domain Authority is a score (from 1 to 100) developed by Moz that predicts how well an entire website will rank on search engines. It measures the "strength" of your entire root domain (e.g., yoursite.com or yoursite.blogspot.com).
The Blogger Master Blueprint for DA:
It’s an aggregate score: DA isn’t about one single post. It’s a reflection of your blog's total profile.
The power of backlinks: The single most important factor in DA is the quality and quantity of external links pointing to your site. Google views these links as "votes of confidence."
Page Authority (PA): The Power of a Single Post
Page Authority is a score (from 1 to 100) that predicts how well a specific page or individual blog post will rank.
The Blogger Master Blueprint for PA:
DA vs. PA: DA is the reputation of the university; PA is the GPA of one specific student.
The "Link Juice" effect: A post on a brand new, low-DA site can still have a high PA if that specific post gets amazing backlinks or goes viral.
Blogger SEO: The Custom Domain Trap
If you are running your blog on the free yoursite.blogspot.com subdomain, you are starting behind the line.
While blogspot.com itself has an extremely high DA (it’s a Google property), that authority is shared among millions of small sites. Google views a custom domain (yoursite.com) as significantly more authoritative than a free blogspot.com address.
Blogger Master Recommendation: The fastest way to boost your potential DA is to move to a custom domain. For just $10/year, you instantly signal to Google that your brand is professional and long-term.
Your 4-Step Action Plan to Increase Authority
1. Write "Authority" Content
If you want other sites to link to you (which boosts DA), you must create content worth linking to.
Pro Tip: Write deep-dive "Ultimate Guides" (2,000+ words). These are much more linkable than short, basic posts.
2. Perfect Your Interlinking
This is the most powerful weapon in the Blogger arsenal. When you link from an old, high-PA post to a brand-new post, you are passing "link juice."
The Setup: Use the "Insert Link" button in the Blogger editor strategically. Every new post should link back to at least three of your high-performing evergreen posts.
3. Build Niche Backlinks
Ten links from small, related travel blogs are far more powerful than one link from a huge, unrelated news site. Focus on relevant authority.
The Move: Guest post on authority sites in your niche to earn high-quality links.
4. Audit Your Spam Score
As we discussed in The Ghost in the Domain, bad backlinks will poison your authority.
The Check: Regularly use Moz’s free Link Explorer to check your Spam Score. Disavow toxic links immediately.
Authority is an Investment, Not an Instant Result
Increasing your Domain Authority from 1 to 20 is relatively easy. Moving from 20 to 50 is a marathon. At Blogger Master, we remind our readers that DA and PA are not short-term games. Keep writing high-quality content, connecting your custom domain, and building high-trust links, and you will become an authority that Google cannot ignore.
