Start with search evidence
Google canonical URL guidance recommends a clear canonical URL so the same content does not split signals across multiple addresses.
AI tool sites, resource libraries, and daily archives should align extensionless URLs, .html variants, canonicals, sitemaps, and internal links around one reader-friendly entry.
Visibility is not demand
The useful question is not whether the page appeared somewhere; it is whether the search term, page promise, and next action fit the same reader job.
Check the page path
- Check canonical, sitemap, hreflang, and internal links for about, archive, topic, and daily pages
- Keep the test narrow: one priority page with clear topic, source links, internal links, and a conversion action
What still needs proof
Duplicate entries split search signals and make external references less consistent. Keep the original source open so the announcement, the evidence, and this site's interpretation stay separate.
