Before improving an answer, confirm that it can be found, understood and attributed to the correct URL.
Direct answer
An inventory of important URLs, their actual state and verified obstacles. Each issue is tied to a page, observable evidence, likely impact and a correction decision.
01 / Review method
List canonical pages, language variants, visual resources and journeys that genuinely matter.
Compare HTTP status, redirects, robots, robots meta, canonical, sitemap and HTML served without running JavaScript.
Review headings, main text, links, images, structured data and navigation in the final DOM on desktop and mobile.
Rank issues by effect, fix them at source, then check the page, language variant and incoming links.
02 / Evidence to keep
Keep the exact address, check date and HTTP status.
Record robots, noindex, canonical, redirects and access to main content.
Verify reciprocal hreflang URLs and the language actually visible.
Check src, dimensions, context, useful alt text and file weight.
03 / FAQ
No. It helps discovery but cannot fix a wrong status, inaccessible content or an inconsistent canonical.
No. Variants without distinct value and service pages may stay outside the index when that choice is deliberate.
