Site Health

Definition

Site health scores are proprietary calculations that vary by tool, but they share common components: **Issue severity weighting**: critical issues (pages returning 5xx errors, correct pages returning noindex, missing canonical tags causing duplicate content) reduce the score more than warnings (non-critical missing meta descriptions, suboptimal image alt text). **Coverage denominator**: most tools calculate (issues found / total pages audited) in weighted form — a site with 1,000 pages where 50 have critical errors has a different health score than a 10-page site with the same 50 errors. **Category components**: technical crawlability (robots.txt, sitemaps, HTTP status codes), on-page elements (title tags, meta descriptions, headings), performance (Core Web Vitals or Lighthouse scores), links (broken internal/external links, redirect chains), and structured data (schema errors). **How to interpret site health scores**: the absolute number is less meaningful than the trend (is the score improving over time after fixes?) and the breakdown by category (a 72/100 overall score driven by a 35/100 structured data category tells you where to focus). Comparing scores between different tools is misleading because their calculations differ. **Common false positives in site health**: tools sometimes flag intentional configurations as issues — noindex on thank-you pages (correct), canonical tags on paginated content (often correct), or low word count on intentionally brief resource pages. Always review findings for context rather than applying fixes mechanically. **Practical health thresholds**: there is no universal "good" score. Focus on eliminating criticals and addressing warnings that affect high-traffic page templates.

Why it matters for SEO

Site health metrics are most valuable as a trend monitoring tool — setting a baseline after an audit, fixing identified issues, and watching the score improve provides objective evidence that technical SEO work is progressing. For large sites with recurring audits, a sudden site health drop is an early warning signal of a deployment regression (accidental noindex, robots.txt change, broken canonical pattern) before it appears in ranking data.

How DeepSEOAnalysis checks this

DeepSEOAnalysis computes an overall SEO score and category subscores (technical, on-page, structured data, performance, AI visibility) based on weighted check results. Critical findings reduce scores more than warnings; informational findings have minimal score impact. The breakdown by category shows where the most significant issues are concentrated.
