Ready-to-share URL

This tool builds links; it does not measure clicks. Reports require an analytics tool on the destination website. The six fields above replace matching UTM parameters already in the URL.

GOOD TO KNOW

A few clear answers.

Let’s make the technical terms a little simpler.

What is a UTM link and how does campaign tracking work?

UTM parameters describe the source, medium and campaign of a link. For example, instagram / social / summer_sale distinguishes visits from that promotion. Astrotor creates the tagged URL on your device; it does not track clicks or connect to your analytics account. To see campaign reports, the destination website needs an analytics tool that reads UTM parameters, with the appropriate tracking configuration and consent.

Which UTM parameters should I use: source, medium or campaign?

Use source for the publisher or referrer, such as instagram or newsletter; medium for the channel, such as social, email or cpc; and campaign for the promotion name. These three fields are required in this builder. Optional content distinguishes links or creatives, term identifies paid keywords, and ID supplies a campaign identifier. Keep a consistent naming convention: uppercase and lowercase values can appear separately in analytics reports.

Does adding UTM parameters change my existing URL?

The destination path, other query parameters and #fragment are preserved. The six supported UTM fields replace matching parameters already present in the URL; leaving an optional field empty removes that matching parameter. Other UTM fields are left intact. Spaces and special characters are URL-encoded automatically. Check the final link before sharing, especially when using signed URLs whose validity depends on an unchanged query string.

Where should I use UTM links, and what should I avoid?

Use tagged links in external campaigns: social posts, newsletters, ads or QR codes. Avoid adding campaign tags to routine internal navigation, because this can complicate attribution. A UTM link is visible to anyone receiving it, so never include names, email addresses or other personal information. This tool neither shortens links nor stores a campaign history; copy the finished URL into your own campaign plan.
