UTM Link Builder

UTM parameters are the query strings analytics platforms read to attribute traffic: source, medium, campaign, term and content. This builder appends them to your URL with correct percent-encoding, so spaces and special characters survive the trip through ad platforms, QR codes and mail clients.

Agree on naming conventions before you build links — lowercase, dashes, no dates inside campaign names — or your reports will fragment into near-duplicate campaigns.

Frequently asked questions

Which UTM parameters are required?

utm_source and utm_medium are the ones analytics tools depend on: source names the referrer, medium the channel (cpc, email, social). utm_campaign is strongly recommended; utm_id, utm_term and utm_content are optional.

Do UTM parameters hurt SEO?

Not if handled correctly. Crawlers may treat tagged URLs as duplicates, which is exactly what a self-referencing canonical solves — that is why the canonical generator pairs well with this tool.

Is capitalization in UTM values significant?

Yes — utm_campaign=Spring and utm_campaign=spring count as two campaigns in most analytics tools. Standardize on lowercase and your reports stay clean.
