Everything you need to know about our services and tools
Domain Authority (DA) is a search engine ranking score that predicts how likely a website is to rank in search engine result pages (SERPs). The Domain Authority score ranges from 1 to 100, with higher scores corresponding to a greater ability to rank.
DA is calculated using our proprietary algorithms that consider multiple factors including the number of linking root domains, the quality of those links, and other SEO signals. It's a comparative metric, meaning it's most useful when comparing one site to another or tracking the "ranking strength" of a website over time.
Page Authority (PA) is similar to Domain Authority, but it predicts the ranking strength of a specific page rather than an entire domain. Like DA, PA is scored on a 100-point logarithmic scale.
Page Authority is useful for understanding the relative strength of individual pages on your site and can help you identify which pages have the best potential to rank well in search results.

Your data security is our top priority:

Domain Authority is a comparative metric, so what's considered "good" depends on your industry and competitors. Generally:
The best approach is to compare your DA to your direct competitors rather than aiming for an arbitrary number.
No, Google does not use Domain Authority in its ranking algorithm. Domain Authority is a metric we calculate to help SEO professionals understand the relative strength of websites.
However, many of the factors that influence Domain Authority (like quality backlinks, domain age, and content quality) are also important ranking factors for Google. So while Google doesn't use DA directly, improving your DA often correlates with improving your Google rankings.

Account benefits (optional):
Even with an account, we only store account information (username, email, hashed password) and usage logs (domain names, dates). No processed content is stored.
Our Domain Authority checker uses our own proprietary algorithms and systems. The metrics are calculated using advanced algorithms developed by our team to provide accurate SEO analysis.
The accuracy depends on:
For most established websites, the scores are highly accurate and updated regularly. New domains or sites with very few links may show lower scores until they're fully analyzed by our systems.
Spam Score is a metric that identifies the percentage of features on a website that correspond to sites that have been penalized or banned by Google. It's calculated using a machine learning model that analyzes on-page features, not backlinks.
Spam Score ranges:
A low Spam Score doesn't guarantee a site is safe, but a high score indicates potential issues that warrant investigation.
We use Google reCAPTCHA v3 to protect our service from abuse and ensure fair usage for all users. reCAPTCHA v3 works in the background and doesn't require you to solve puzzles or check boxes.

For most active websites, DA scores are updated regularly. Major changes in link profiles may result in more frequent updates.
Domain Authority (DA) is a metric that measures domain strength, while Domain Rating (DR) is an equivalent metric used by other tools. Both measure domain strength, but they use different algorithms and data sources:
Both metrics are useful for SEO analysis. Many professionals check both to get a comprehensive view of a domain's authority. Our tool provides DA and PA metrics using our own proprietary systems.
