Conflict of URLs by upper and lower case
Different spellings can create duplicate URLs.
Different spellings can produce duplicate URLs The error should never be assessed in isolation. What matters is which URL group is affected and whether it creates a crawling, indexing, snippet, performance or quality problem.
Standardize path writing based on real variants
While hostnames are handled without capitalization, paths such as /advice and /advice can be processed differently. Check both variants directly. If they deliver the same content, the preferred spelling in Navigation, Canonical and Sitemap should be used consistently.
Example: Recognizing the Result
Illustrative example: /Consultation/ and /Consultation/ provide two answers for the same performance on this server. An image path with capital letters is at the same time an actually different file.
Limit cause and implement correction
After normalization, also test file paths and parameter values. A blanket capping of each string can damage resources on systems with distinguishable filenames. Old public variants should traceably lead to the selected version without creating a new forwarding loop.
What makes you recognize a suitable correction
Set the desired content address and forward affected variants in a controlled manner. Test files, IDs, and other wholesale/small write paths.
Classification and boundaries
When is this indication not a clear error?
URL paths are not lump-sum independent of upper/lower case. Global transformation can damage existing resources.
Conflict of URLs by upper and lower case after CMS and cause
Many audit messages can be resolved faster if they are grouped by system, page type and technical cause. CMS indentations are only linked where URL conflict has its own cause or fixed route in the respective system through capitalization and lower case.
For this error, there is currently no own CMS deepening, because the correction is usually not sufficiently system-specific. Take advantage of the general causes and checks on this page.
