Eliminating Duplicate Home-Page Variants Caused by Garbage Slash and Query Patterns
Duplicate pages are not always neat alias copies. Sometimes they are malformed path variants that should have ended in a 404 but still resolve to valid content.
Even after fixing normal alias duplicates, some Evolution sites still expose strange URL variants such as repeated slashes, punctuation-heavy tails, or path fragments that resolve to the home page instead of a 404. These are SEO duplicates just as surely as cleaner alternate URLs.
What usually fixes it
- normalize repeated slashes before routing continues
- reject obviously malformed paths early with a 404
- make sure the router does not quietly fall back to the homepage for invalid requests
- pair the routing fix with a canonical strategy for valid URLs
If a malformed request still lands on real content, search engines see that as a duplicate route. Treat path normalization as part of technical SEO, not just URL hygiene.
