A consistent canonical system gives Bing and Google one clear version of every Mars Market information page to discover and evaluate.
Choose a single origin
Use HTTPS and one hostname in canonicals, internal links, structured data, Open Graph tags and robots sitemap references.
Redirect alternative protocol or www forms in one permanent hop where they occur.
Compare the sitemap inventory
Check that every sitemap URL returns success and names itself as canonical.
Pages omitted from the sitemap can still be indexed, but sitemap entries should never contradict page signals.
Inspect live output
Run a post-deployment audit for canonical tags, robots, sitemaps, 404 behavior and schema.
Fix a mismatch before sending URL inspection or IndexNow notifications.
