📈 Spam Score: What It Is & Why It Matters for SEO
Spam score indicates the likelihood that a webpage is engaging in manipulative or low-quality practices that could trigger Google penalties. Our tool focuses on on-page spam signals that are easy to detect – keyword stuffing, hidden text, excessive link density, and unnatural repetition.
