What is Domain Authority? And How to Improve It?

If you’ve ever Googled “how to rank higher on Google”, you’ve certainly come across the term domain authority (DA). It sounds technical and intimidating – but once you understand what it is, how it’s measured, and what actually moves the needle, it becomes one of the clearest roadmaps for growing your blog’s SEO presence.

In this blog post, you’ll learn exactly what domain authority is, what a good score looks like, how to check your blog score for free, and the five most impactful strategies to improve it in 2026.

What is Domain Authority?

Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how likely a website is to rank on search engine results pages (SERPs).

The score runs from 1-100 – the higher your DA, the stronger your site’s ability to compete for keywords in your niche.

KEY FACT
DA is NOT a Google ranking factor. It is a third-party metric created by Moz to estimate how authoritative and trustworthy a domain is, based primarily on the quality and quantity of backlinks pointing to a domain.

Is DA the Same as Domain Rating (DR) or Authority Score?

No, they measure roughly the same. Multiple SEO tools have built their own version of this.

1. Moz ➜ Domain Authority ➜ Score Range: 1-100 ➜ Primary Factor: Backlinks.
2. Ahrefs ➜ Domain Rating (DR) ➜ Score Range: 1-100 ➜ Primary Factor: Quality of referring domains
3. SEMrush ➜ Authority Score ➜ Score Range: 1-100 ➜ Primary Factor: Backlinks, Organic Traffic.

Why Does DA Matter for Bloggers?

1. Keywords Targeting – A blog of DA score 15 going head -to-head with blogs of DA score of 60+ for competitive keywords is losing the battle, but the same blog can dominate long-tail keywords.
   
2. Collaboration and Outreach – When writers hop on to your blog for guest posting or link exchanges, your DA score is often the number editors check.
   
3. Monetization – Ad networks like Mediavine and other premium affiliate programs have informal DA thresholds. Brands reaching out to you for a review post of their tool on your blog often see the DA score.

How Do You Increase Domain Authority? 5 Proven Strategies

The 5 strategies which I usually follow to build my blog’s DA score – ordered from the most to least impactful on your score.

1. Build High-Quality Backlinks – Backlinks from reputable, relevant sites are the single biggest driver of DA. One link from a DA 70 site is worth more than 50 links from a DA 5 site. Quantity matters – but quality is what actually moves your score.
   
2. Create Link-Worthy, Original Content – You cannot build backlinks; the only way to get them is for a high-DA blog to point to yours. The consistent way to build backlinks is to publish content so useful, original, or data-rich that other sites naturally want to reference it.
   
3. Fix technical SEO and Site Structure – Technically broken blogs hold back their DA and rankings regardless of how many links you build. Before starting link-building, make sure your technical foundation SEO is solid.
   
4. Build a Strong Internal Linking Structure – Internal links are the most underused DA-building strategy – this is entirely under your control, costs nothing, and can be implemented right now.
   
5. Audit and Disavow Toxic Backlinks – Low-quality, spammy, or irrelevant links signal weak backlink building to Google, which drags your score down.
