Understanding your website's spam score is critical for SEO. A low score ensures a clean backlink profile, safeguards against penalties, and boosts your search engine rankings. Keeping an eye on this metric can offer valuable insights into your site's performance.
How is Spam Score Graded?
Spam score grades range from low (1%-30%), medium (31%-60%), to high (61%-100%). Different platforms might use various signals for calculation, but the essence is to identify potential red flags in a website's profile.

A zero spam score indicates a 0% chance of the website being marked as spam. This is the optimal score and suggests that the site is highly trustworthy.
