# What is Domain Authority & How to Improve It?

**Domain Authority (DA)** is a metric developed by **Moz** to predict how well a website will rank on search engine results pages (**SERPs**). It is scored on a **scale from 1 to 100**, with higher scores indicating **greater ranking potential**.

Improving **Domain Authority** can enhance your website’s credibility, visibility, and ability to rank for competitive keywords. This guide explains **what DA is, how it works, and the best strategies to increase it**.

***

#### What is Domain Authority?

**Domain Authority (DA)** is a predictive ranking score that **evaluates the overall strength of a website’s backlink profile**. The score is based on multiple factors, including:

**Backlink Quality & Quantity** – The number and strength of links pointing to your site. 

**Domain Age & Trust** – Older, well-established domains tend to have higher DA. 

**Content Quality & Relevance** – High-quality, authoritative content improves DA. 

**Technical SEO & Site Structure** – A well-optimized website enhances credibility.

***

#### How is Domain Authority Calculated?

Moz calculates DA based on over **40 ranking signals**, including:

1. **Linking Root Domains** – The number of unique websites linking to your site.
2. **Total Backlinks** – The total number of inbound links pointing to your domain.
3. **Spam Score** – A lower spam score improves DA.
4. **Search Engine Friendliness** – Proper indexing and crawlability.

**Important Note:** DA **is not a Google ranking factor** but is a useful indicator of **SEO performance**.
