What happens to query parameters already in my destination URL?

Existing non-UTM parameters and the fragment are preserved. Current UTM parameters are replaced with the values you supply rather than duplicated.

Are UTM campaign values case-sensitive?

Analytics systems can treat differently cased values as separate labels. The optional lowercase setting normalizes UTM values only; it never lowercases the destination path or unrelated parameters.

Can every bulk URL use different campaign values?

Yes. Select Per-URL Parameters and add rows or import a CSV with supported UTM columns. One Campaign mode instead applies a shared set to multiple destinations.

Does the analyzer contact my analytics service?

No. It decodes the URL locally and lists recognized, unknown and non-UTM parameters. It cannot confirm visits, attribution, website availability or analytics configuration.

Frequently asked questions

About UTM Campaign URL Builder

Campaign reporting becomes fragmented when source and medium labels drift between links. This builder keeps the standard UTM fields together, offers a few practical starting presets and preserves unrelated destination parameters. Optional lowercase normalization helps teams enforce naming conventions without changing the underlying page address.

Bulk workflows support one campaign applied across many URLs or independent values imported from CSV, with invalid rows separated from exportable results. The analyzer travels in the opposite direction: it decomposes an existing link into its base URL, recognized UTM values, unknown tracking fields and ordinary query parameters. No link is requested and no analytics account is connected.
