Core value
Precise tracking beyond UTM: traditionally, ad traffic tracking relies mainly on UTM parameters. Hidden fields go beyond UTM's limitations, letting you track more granular, more specific, and even identifiable visitor information.
Custom personal/sales tags: using URL parameters, you can pass a personal identifier (like a member ID or sales rep ID) or specific channel information (like a store code or email batch ID) into your form, and have it recorded automatically.
Deeper data integration: these hidden tags become part of your data asset, helping you connect promo participants with data from internal systems (like a CRM or POS) for deeper cross-analysis later.
Key features
Not visible on the form: the field doesn't display on your promo form, so users don't need to do anything.
Automatically tagged: the system automatically records the information you've pre-configured into every submission collected.
Data tagging: useful for highly custom tracking beyond UTM, for example:
Personal identity tracking: automatically pass in a member's Member_ID or a sales rep's Sales_Rep ID when sending an email or SMS from your database/CRM.
Internal channel management: distinguish between different physical stores or sales teams promoting the promo using a Store_Code or Team_Name.
Specific page tagging: mark traffic coming from a specific logged-in page or product page, such as Page_Type: Premium.
📝 Form | Hidden Field Setup Guide
This guide walks you through setting up and using hidden fields in a Feversocial form, so you can automatically track a source tag for each promo participant.
Step 1. Open the hidden field settings page
On the form promo page you're editing, find the "Hidden Field" option in the left-hand menu.
Once you click in, you'll see the field creation area
Step 2. Define your hidden field parameters
Your hidden field's parameter name must match the parameter you add to the URL.
Tip: a single hidden field setup can hold multiple tags. If you want to record several pieces of information at once, click "Add" to add another field pair.
Step 3. Save your settings and test
Once your hidden field setup is complete, be sure to save and test it.
Step 4. View the data
For example, say a form will be sent out by regional sales reps — you could add two parameters to the end of the URL: area and salesid. The form URL would become: "https://form_url?area=Taipei&salesid=bestsales01." When you download the data afterward, you'll see these hidden field parameters added as extra columns next to each submitter's data.
