Shared links often accumulate campaign tags and click identifiers. Cleaning them can make a list easier to compare, but deleting every parameter after a question mark can break search pages, product variants, language choices, and signed downloads.
Separate tracking from functional parameters
Common campaign parameters include utm_source, utm_medium, utm_campaign, utm_term, and utm_content. Advertising systems may also add identifiers such as gclid or fbclid.
Functional parameters are site-specific. Examples include ?page=2, ?lang=fr, ?product=123, or a token used for a temporary download. Their names alone do not prove whether they are safe to remove.
Use an allowlist, not a block-everything rule
Create a small list of parameters you have deliberately classified as tracking-only. Remove names case-insensitively, preserve all unknown parameters, and keep their original values. This is safer than retaining only a guessed set of “important” names.
For example, this URL:
https://example.com/guide?utm_source=newsletter&lang=en#setup
can usually be reduced to:
https://example.com/guide?lang=en#setup
The language selection and fragment remain intact.
Watch for redirects and signed URLs
Short links and email click trackers often redirect through another hostname. Removing their query string may prevent the redirect entirely. Signed cloud-storage links are even more sensitive: several parameters collectively authorize access and include an expiry time.
Do not clean authentication, invitation, password-reset, checkout, or private-document URLs. Treat them as sensitive and avoid putting them into shared link inventories.
Validate the result
- Keep the original URL beside the cleaned version.
- Compare hostname, path, and retained parameters.
- Open a small sample in a private browser window.
- Confirm the final page and visible state match.
- Record the removal rule for repeatable future batches.
A clean URL is useful only when it still identifies the intended resource. Conservative parameter removal gives you readable links without silently changing what they do.
