Weighted Issue Categories

Issues are classified into nine categories: indexability, meta tags, content, links, performance, images, structured data, security, and mobile. Each category carries a different weight in the overall score calculation. Critical issues in high-weight categories like indexability and meta tags have a larger impact than minor issues in lower-weight categories.

Severity and Coverage Multipliers

Each issue has a base penalty modified by coverage (percentage of pages affected), page importance (based on traffic and link equity), and visibility (search console impression data when available). A critical issue affecting 90 percent of pages carries a much higher penalty than the same issue on a single page. Site-size tiers adjust penalties so small sites are not unfairly penalized for issues that naturally affect fewer pages.

Confidence and Data Sources

The score confidence level increases when you connect Google Search Console and Google Analytics. Without these data sources, the score relies solely on crawl data. With GSC connected, visibility multipliers are applied to weight issues on high-impression pages more heavily. This ensures the score reflects real-world search impact rather than just technical compliance.

Score Interpretation

A score of 90 to 100 indicates excellent SEO health with minimal issues. Scores between 70 and 89 are good but have room for improvement. Scores from 50 to 69 indicate moderate problems that could affect rankings. Below 50 means critical issues need immediate attention.
