Redirects for Parameter URLs: When to Normalize, When to Keep Them, and When to Ignore Them
Parameters are not automatically an SEO error
Some parameters are harmless, some are useful, and some create duplicate URLs that should not compete in search. Redirecting all of them the same way usually creates new problems.
Decide based on purpose
Ask whether the parameter changes content, supports tracking, controls sorting or filtering, or exists only because of a technical artifact. Different purposes need different handling.
Practical choice
Normalize parameters only when they create duplicate navigational URLs. Keep the useful ones intact for tracking or user experience, and avoid redirect rules that erase meaningful context.
