Frequently Asked Questions

Common questions about our Domain Authority Checker.

Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how likely a website is to rank in search engine result pages (SERPs). It is scored on a scale from 1 to 100, with higher scores corresponding to a greater ability to rank. Domain Authority is calculated by evaluating multiple factors including linking root domains, total number of links, and the overall link profile quality. It is widely used by SEO professionals to compare websites and track ranking strength over time.
This tool provides an estimated domain score based on observable domain characteristics that correlate with strong SEO performance. The algorithm evaluates factors such as the top-level domain quality (.com, .org, .net), domain name length and readability, the presence or absence of hyphens, whether the URL uses HTTPS for security, and keyword presence in the domain name. Each factor contributes points to produce a score from 0 to 100. This is not a replacement for the official Moz Domain Authority metric, which is based on backlink data and machine learning.
No. The official Moz Domain Authority score is a proprietary metric that uses backlink data, link quality analysis, and machine learning models to predict ranking potential. This tool provides an estimated score based on publicly observable domain characteristics such as TLD, domain length, SSL usage, and naming conventions. For the official DA score, we provide direct links to Moz Link Explorer, Ahrefs, and Semrush where you can check the authoritative metrics for free or with a trial account.
Improving Domain Authority requires a long-term SEO strategy. Key actions include building high-quality backlinks from reputable and relevant websites, creating valuable and shareable content consistently, optimizing on-page SEO including title tags, meta descriptions, and internal linking, ensuring your site is mobile-friendly and loads quickly, using HTTPS for security, removing toxic or spammy backlinks using disavow tools, and maintaining a clean site structure with proper technical SEO. Domain Authority typically improves gradually over months and years of consistent effort.
Domain Authority scores range from 1 to 100. Generally, a score between 40 and 50 is considered average, 50 to 60 is good, and above 60 is excellent. New websites typically start with a DA of 1 and build up over time. Scores above 80 are usually reserved for established, high-authority sites like major news outlets, government sites, and well-known brands. It is more useful to compare your DA against direct competitors rather than aiming for an absolute number, since DA is a relative metric.
Yes, this Domain Authority Checker is completely free to use with no limits on the number of domains you can analyze. There is no registration or sign-up required. All analysis runs entirely in your browser, and no data is sent to any external server. You can also compare two domains side by side at no cost. For official Domain Authority scores, use the linked tools from Moz, Ahrefs, or Semrush, which may require free or paid accounts.
