Transfer utm_source in Wordpress

Thanks Liz, Yes that works.

Answer is to add:

data-transferable-url-parameters="utm_source, utm_medium”

Immediately after:

data-mode="your embed mode"

Since it's a popup embedded on your WordPress site (not a hosted Typeform you're linking out to), this is actually straightforward using Typeform's own hidden fields.

Add a hidden field to your Typeform called utm_source, then make sure your ad links point to a page with `?utm_source=xxx` in the URL. When someone triggers the popup and submits, Typeform will pull that value straight from the URL into the field, and you'll see it in Results.

The one catch: this only works if the visitor is still on that same page (with the UTM still in the URL) when they submit. If they land on your homepage, then click through to another page before opening the popup, the UTM is gone and there's nothing for Typeform to grab.

If that's what's actually happening (worth checking first, since it's the most common reason this "stops working"), you'd need something to capture the UTM on arrival and hold onto it until the form is submitted, even if that happens several pages later. That's essentially what Attributer.io does, it stores the value in a cookie on landing and writes it into the hidden field whenever the popup is eventually completed (disclosure: I'm the founder). As a side effect it also fills in a source for visits with no UTM at all, like organic search or direct traffic, if that's useful to you.
