How to Read Your Results

Content Score (0-100): A weighted blend of keyword density (30%), content length (20%), heading structure (15%), external links (15%), images (10%) and keyword placement (10%). Think of it as a quick on-page health snapshot, not a Google ranking guarantee.
Keyword Density: Your keyword occurrences divided by total words, as a percentage. Stay between 0.5% and 2.5% — below that you look irrelevant, above that you risk keyword stuffing.
SEO Health tiers: 80+ is Excellent, 60-79 is Good, 40-59 is Fair, and below 40 is Poor. Use the Improvement Suggestions below to lift the weakest dimensions first.
