Without UTM tags analytics is blind: “came from somewhere” instead of “came from the August 15 Telegram post”. Tags are five link parameters that analytics systems use to split traffic by source, channel and campaign. The builder assembles the link to standard: presets for common channels, correct parameter joining, nothing sent to a server. Make a slug for a new page with the slug generator and wrap offline links into a QR code. The rest of the tools are in one section.
The five tags: what goes where
utm_source — where traffic comes from (telegram, facebook, google); utm_medium — channel type (social, cpc, email); utm_campaign — campaign name (august_sale); utm_term — the search keyword in paid search; utm_content — the ad variant when there are several. The first two are mandatory. Above all, consistency: analytics treats “fb” and “FB” as different sources.
A naming convention: agree once
Tag chaos buries analytics faster than missing tags: telegram, tg and Telegram land in three separate report rows. Keep a dictionary: latin only, lowercase only, underscores between words. The builder's presets insert canonical source/medium pairs — a ready-made convention.
Where tags are mandatory and where they hurt
Mandatory: paid ads, newsletters, seeding, social posts, QR codes, influencer links. Harmful on internal site links: a click on a tagged internal link breaks the session and pollutes reports. The rule: tags only on inbound links from outside.

Why UTM tags?
Analytics splits traffic by source and campaign — you see what brings customers and what burns budget.
Which tags are required?
utm_source and utm_medium. Add utm_campaign when you run more than one campaign.
Upper or lower case?
Lowercase everywhere: “Telegram” and “telegram” are different sources in reports.
Are tags visible to recipients?
Yes, they're part of the link. Wrap it in a shortener for looks.
Can I tag internal site links?
No: a tagged internal click breaks the analytics session.
Do the tags affect SEO?
Tagged pages can duplicate content — canonical tags solve it; never tag internal links.
Do I need an account?
No: the builder runs in your browser with no limits.
Is my data uploaded?
No, the link assembles locally.
