What This Tool Does
View the server-delivered HTML of a public page to inspect metadata, headings, links and content present before JavaScript runs. It displays provider-reported information and clearly distinguishes unavailable data from measured results.
How to Use the Results
Compare server HTML with what appears in your browser when diagnosing client-rendered content and indexing issues.
Why This Check Matters
Focused checks help website owners and agencies identify specific improvements without confusing one metric with an entire SEO strategy. Review the evidence, compare it with the live page, and prioritize changes that improve clarity, accessibility and user experience.
