Metrics the Tool Will Show
Domain Authority (0–100)
Overall SEO authority score based on link profile quality and quantity. The primary benchmark for comparing domains.
Referring Domains
Total unique websites linking to the domain. The single most important link metric — more diverse referring domains = stronger authority.
Trust Score
A measure of how trustworthy the domain appears based on link sources. High trust scores mean links come from legitimate, authoritative sites.
Spam Score
Identifies domains with suspicious link profiles that may be penalized by Google. Essential for vetting potential link partners.
How the Domain Authority Checker Will Work
Enter a domain name and the tool instantly queries the SE Ranking domain metrics API, which maintains a continuously updated index of domain authority scores for millions of websites. Results appear within seconds and include the core authority metrics alongside historical trend data.
The bulk comparison mode lets you enter up to 10 domains simultaneously. Side-by-side comparison tables make it easy to benchmark your domain against competitors or to qualify guest post sites and potential link partners before committing to outreach.
Domain authority scores change over time as a domain acquires or loses links. The tool shows a 12-month authority trend chart so you can see whether a domain is growing in authority (positive signal) or declining (possible penalty or link loss). Domains with downward trends are risky link targets.
The spam score component specifically flags domains with unnatural link profiles — such as sites that have received thousands of links from link farms or private blog networks. This is critical for avoiding associating your domain with toxic link sources, which can pass negative ranking signals through unnatural links.
Frequently Asked Questions
What is Domain Authority and how is it calculated?
Domain Authority (DA) is a 0–100 score that predicts how likely a domain is to rank well in search results. It's calculated based on the number and quality of backlinks pointing to the domain, the authority of those linking domains, and the overall link profile health. Higher DA correlates with stronger organic search performance, though it's a predictive metric, not a direct Google ranking signal.
What is the difference between DA and DR?
Domain Authority (DA) is a metric developed by Moz based on their link index. Domain Rating (DR) is a similar metric from Ahrefs based on their link database. Both measure link-based authority on a 0–100 scale but use different data sources and formulas. Our tool shows both alongside our own trust score so you can cross-reference signals for a complete picture.
Can I check multiple domains at once?
Yes. The bulk domain authority checker lets you input up to 10 domains simultaneously and compare their DA, referring domain counts, and authority scores side by side. This is ideal for competitive analysis and for vetting potential link-building targets or guest post sites.
