Guide: Domain Authority & Page Authority
What is Domain Authority (DA)?
Domain Authority is a search engine ranking score developed by Moz that predicts how likely a website is to rank in search engine result pages (SERPs). Scores range from 1 to 100, with higher scores corresponding to a greater ability to rank.
What is Page Authority (PA)?
Page Authority measures the predictive ranking strength of a single individual page rather than an entire domain. Like DA, PA ranges on a logarithmic 100-point scale.
Understanding Spam Score (SS)
Spam Score represents the percentage of sites with similar features that have been penalized or banned by Google. Scores range from 1% to 100%:
- 1% - 30%: Low Spam Score (Healthy)
- 31% - 60%: Medium Spam Score
- 61% - 100%: High Spam Score (Risk of penalties)
How to Improve DA & PA
Authority metrics are heavily based on your backlink profile. You can raise scores by obtaining high-quality external links from authoritative websites, removing spammy backlinks, and structuring robust internal linking patterns.
