utm_campaign=campaign_name

[Damian Dervil]

how to do it because I added this code and nothing changes

<iframe src="https://trade.mql5.com/trade?demo_all_servers=1&amp;startup_mode=open_demo&amp;lang=ru&amp;save_password=off&amp;utm_campaign=campaign_name" allowfullscreen="allowfullscreen" style="width: 100%; height: 100%; border: none;"></iframe>

Is this what this is about?

utm_campaign=some;campaign_name=sie.com;

how to do it please?
