Domain authority is an indicator of your website’s trustworthiness and visibility within search engines.
It reflects how well your domain performs in terms of SEO compared to other websites. In this article, you’ll learn exactly what domain authority is, why it matters for your online visibility, and how to strengthen it step by step.

What is domain authority?

Domain Authority (DA) is a score ranging from 0 to 100, developed by the SEO platform Moz. This metric predicts how likely a website is to rank well in search engine results. The higher the score, the stronger the domain.

Domain Authority is calculated based on factors such as:

  • The number of backlinks pointing to your website
  • The number of unique root domains linking to your site
  • The overall quality of those links

Note: This score is not provided by Google itself but is a third-party metric intended to help you track your SEO performance relative to competitors.

How high should your domain authority be?

Domain Authority is important because it increases your visibility in Google, drives more organic traffic, and improves your conversion potential. Search engines like Google prefer websites they consider trustworthy and relevant. A high Domain Authority therefore increases your chances of securing top rankings. If you’re competing against websites with a higher score, you’ll need to put in significantly more effort to outperform them.

Top positions generate the most traffic: position #1 typically gets ten times more clicks than position #7. So don’t settle for just being on page one—actively optimize to strengthen your authority and expand your organic reach. More visibility means more visitors, higher conversions, and ultimately greater revenue. That’s why businesses of all sizes continuously invest in improving their Domain Authority.

How do you increase your domain authority?

You can increase your domain authority by improving your technical SEO, publishing high-quality content, using smart internal linking, and acquiring backlinks from authoritative websites. This process requires time and consistency, but over the long term it leads to higher rankings, stronger credibility, and more sustainable organic traffic.

1. Establish a Solid Technical Foundation

Search engines prioritize websites that are technically sound. Ensure fast loading times, a secure HTTPS connection, mobile-friendliness, and correct schema markup implementation. In other words, make sure your technical SEO is in top shape.

Technical SEO can be complex—avoid making changes unless you have the necessary knowledge. If you’re unsure, it’s better to hire a specialist than risk causing more harm than good.

2. Create In-Depth, Long-Form Content

Without content, Google can’t understand the context of your pages. You won’t rank with just images, videos, or a couple of lines of text. Content is essential to provide relevance and meaning.

Write high-quality, comprehensive content that delivers value to your visitors. Start with keyword research to understand your audience’s search behavior. Publishing a large volume of relevant content around a focused topic helps position your website as an authority—making it more likely others will share and link to your pages.

3. Improve Internal Linking

Build a clear internal link structure by connecting related pages within your site. These internal links help Google crawl and understand your website more efficiently. Pages without internal links are harder to discover and rank.
Use your target keywords and variations as anchor text to guide both users and search engines.

4. Build Backlinks to Increase Authority

Backlinks from external websites are a key factor in improving domain authority. Focus on earning links from relevant, trustworthy domains with strong authority—these have the most impact.

Avoid link farms and unnatural link-building practices. Remember, effective link-building takes time; results often appear weeks or even months later.

By consistently working on these four pillars, you’ll steadily grow your domain authority—and see the difference in your search rankings.
