Tracking Traffic Medium

You are able to set up Zuko so that it tracks the medium by which traffic arrives on your web form or checkout. The tracking is based on the UTM Medium code - the type of link that drove the individual to your web domain. If there is no UTM Medium available, Zuko will look at the referring domain to establish what the medium was. This will then show up in the custom attributes filter of your Zuko dashboard under the "trafficMedium" category so you can select the medium(s) you wish to view in the data.

Setting up the tracking

The tracking can be enabled through adding one piece of code to all the pages of the web domain your form is hosted on. Note that this must be added to all pages to track accurately - your visitors will likely not be coming directly to your form page but from other landing pages on your site so it is important to track where they were immediately before they arrived.

The code to add all pages of your site is:

<script src=""></script>


This can be done manually or through a tag manager. We’ve outlined a step-by-step to accomplish this through Google Tag Manager but other managers have similar processes.

Using Google Tag Manager

Firstly, click the “Add a new tag” button. Then, label it appropriately, select “Custom HTML” for the Tag Type and paste in the Zuko code into the HTML section.

Once you have done that you can set the trigger. Click into the trigger box to get up the standard trigger list and select “All Pages”.

You can then save the tag and submit it and Zuko will start pulling in the UTM Medium tracking right away.

What will it show me?

As mentioned above, the tracking will pull in the UTM Medium code or type of referrer, showing what medium  the traffic to your form / site has come via. Specifically, it will show:

Custom UTM code

If you have set up UTM Medium codes on any external source (e.g. email, PPC, digital display, afficiliates, etc), Zuko will prioritise this as the medium it will pull through. The best practice is to make sure that you add a UTM code to all external sources that you control so you track it accurately. If you use an external email provider, check whether it automatically adds a UTM_medium to all links or if you need to add it yourself.

There are plenty of UTM code building tools that can help you create a link if you need help creating one.


If a visitor has reached your site through a search engine result (for example Google or Bing) that is not a paid for link, Zuko will track this as “Organic”, letting you segment your data by people who found your site in this way.


Referral traffic is visitors who have reached your site by clicking a link that is hosted on another domain as long as that domain isn’t a search engine or the link does not have its own UTM medium as part of it (where specific UTM_mediums have been set up they override other categories).


Where Zuko is unable to detect any of the above categories it will classify the medium as “None”. Typically this will mainly be direct traffic (visitors typing in your URL directly into the browser) although it may also contain sources which have no UTM built into their link. For example, if you send an email out which has links that have no UTM they will fall into this category.
