Domain Authority (DA) is a metric that reflects the ranking potential of an entire website in search engine result pages (SERPs). It is measured on a scale from 1 to 100. Domain Authority is calculated using multiple factors, including the number of backlinks, domain age, total number of unique referring domains, social signals, and overall link quality.
A stronger backlink profile generally corresponds to a higher domain authority score. Conversely, if a website has low-quality or spammy backlinks, its DA tends to be lower.
Page Authority (PA) predicts how well a specific page (rather than the whole site) is likely to rank on SERPs. Like DA, the PA score ranges from 1 to 100, and it's based on similar factors — but evaluated at the page level rather than the domain level.
Below are proven ways to improve your website's domain authority:
Acquire links from authoritative websites within your niche. Backlinks from credible sites signal to Google that your website is trustworthy — improving both domain and page authority over time.
Publish high-quality, original content that addresses real user needs. Helpful content improves engagement and naturally attracts backlinks, both of which contribute to higher DA scores.
Spammy backlinks can negatively affect your domain authority. Regularly audit your backlink profile and disavow or remove harmful links to maintain steady DA growth.
Improve site speed, fix broken links, write clear meta titles and descriptions, and ensure your site is mobile-friendly. Solid on-page SEO supports a healthy DA over the long term.
There is no fixed "good" or "bad" DA score. In general, the closer a website's DA is to 100, the stronger its authority. The closer it is to 0, the weaker. Below is a general guide:
| Domain Authority | Level |
|---|---|
| 0 – 10 | Very weak |
| 10 – 30 | Weak |
| 30 – 40 | Acceptable |
| 40 – 50 | Average |
| 50 – 60 | Good |
| 60 – 90 | Excellent |
| 90 – 100 | Ideal |
Spam Score uses 17 flags (factors that may indicate a spammy profile) to estimate how spammy a website is. The more flags, the higher the probability of being seen as spam:
| Number of flags | Probability of spam |
|---|---|
| 0 – 4 | 0.5% – 7.5% (low risk) |
| 5 – 7 | 11% – 30% (caution) |
| 8 – 17 | 56% – 100% (high risk) |
As a rule of thumb, Spam Score under 5 is healthy; scores of 8 or above are warning signs.
Maintaining high DA and low Spam Score helps you focus on the ranking factors that actually move the needle:

No. Google has consistently stated that it does not use Domain Authority as an official ranking factor. DA is a third-party metric created by Moz to estimate how likely a site is to rank in SERPs — useful for benchmarking and competitive analysis, but not an official Google signal.
The following are widely accepted best practices that can help improve search visibility:
Domain Authority itself is not an SEO ranking factor used by Google. However, it is a widely used third-party metric that SEO professionals rely on to evaluate the relative authority of websites and benchmark performance against competitors.
