Industry Benchmarks & Score Interpretation
Understanding what constitutes healthy telemetry helps prioritize high-impact engineering fixes over minor micro-optimizations.
| Metric / Signal | Optimal (Good) | Needs Polish | Critical (Poor) |
|---|---|---|---|
Robots.txt HTTP Availability A 500 error causes Googlebot to postpone crawling completely to protect your server. | HTTP 200 OK with valid text/plain format | HTTP 404 (Default allow-all) | HTTP 500 Server Error (Halts all crawl) |
Rendering Asset Access Googlebot requires stylesheet and script execution to render and evaluate your mobile layout accurately. | CSS, JS & WebP files open for crawl | Some fonts blocked | Disallow: /wp-content/ or /static/ |
XML Sitemap Hygiene Submitting dirty sitemaps wastes crawl budget and delays new product or article discovery. | < 50,000 canonical HTTPS URLs with lastmod | Missing lastmod tags | Contains 404s, redirects, or HTTP URLs |
