Understanding Your Results
Domain Authority (DA)
A logarithmic scale from 1 to 100 predicting how well a website will rank. Growing from 20 to 30 is much easier than growing from 70 to 80.
Linking Domains
The number of unique websites (root domains) that link to this domain. This is generally more important than total backlinks.
Spam Score
The percentage of sites with similar features that have been penalized by Google. A score below 10% is considered safe.
