The problem: you don't know where your traffic came from
You posted the same link on Instagram, Telegram, and in an email — and got clicks. But which one actually worked? Without any tagging, they all look identical in your stats, so you can't tell which channel is really pulling its weight.
What UTM parameters actually are
UTM parameters are small tags appended to the end of a link: utm_source (the channel, e.g. instagram), utm_medium (the type, e.g. social or email), and utm_campaign (the campaign name, e.g. summer_sale). Any analytics tool can read them and group clicks by these values.
How to add UTM parameters to a link on ilnk.uz
Add the parameters to your original long link before shortening it, e.g.: https://example.com/sale?utm_source=telegram&utm_medium=social&utm_campaign=summer_sale. Once shortened, the short link keeps every tag — they're just tucked behind the short address.
Where to see the results
Your link's analytics dashboard on ilnk.uz groups clicks by source — you'll immediately see, for example, that Telegram drove 340 clicks and Instagram drove 120, even though it was the same underlying link.
A practical tip
Use the same naming convention across every campaign (e.g. always utm_medium=social for social posts) — that keeps your data easy to compare month over month, instead of a mess of inconsistent labels.
