Is this the same as Moz DA and PA?
No. Domain Authority and Page Authority are Moz's own metrics, built from Moz's index of links across the web, and only Moz can calculate them. These scores are ours, from a live check of the site itself, so they will not match Moz or other tools. Every check behind each score is shown.
How is the Domain Score worked out?
Out of 100 points: domain age (30), secure https (10), site size from the sitemap (15), robots.txt (5), about, contact, privacy and terms pages (15), structured data (5), social profiles (5), speed (5), a clean domain name (5) and whether search engines may index the homepage (5).
How is the Page Score worked out?
Out of 100 points of on-page SEO for the exact URL: it loads and can be indexed (15), title tag (15), meta description (10), one main heading (10), content depth (15), internal links (10), image alt text (5), canonical tag (5), mobile viewport (5), declared language (5) and structured data (5).
What does Spam Risk mean?
It adds up warning signs that often appear on spam sites, such as a parked or brand-new domain, gambling or pharma keywords, very little content, missing contact details or far more outgoing than internal links. 0-30% is low, 31-60% medium, 61-100% high. A high value is a reason to look closer, not proof that a site is spam.
Why did a site fail to load?
Some sites block automated visitors, answer too slowly, or have an invalid security certificate. The checker only visits public websites and gives up after about 25 seconds.
