Use AdUp Technology's conversion tracking to find out which of your campaigns and keywords are most efficient and thereby increase your ROI. You can also track which actions follow a click on an ad, such as purchasing a product or signing up for a newsletter. 

How it works

All you need to do is create a conversion code and integrate it on your page where the conversion happens (e.g. on the booking confirmation page) using an <img> tag.​ As soon as a user arrives on your website by clicking on an AdUp advertisement, a temporary cookie is stored, through which the conversion is then registered or tracked.

Create conversion code

Step 1

Log in to the Advertiser Front-End here with your access details. 

Step 2

Click on the "Tools" tab and select "Conversion Tracking".

Step 3

Now generate a new conversion code by clicking the "Create conversion code" button.

Step 4

Assign a name and define the type (for internal classification purposes only):​

  • Enquiry

  • Registration

  • Page view

  • Sale

  • Other

Step 5 (optional)

Specify a value for the conversion (this and other values can also be passed dynamically later when calling the conversion tag via URL parameters).

Step 6 (optional)

Change the counting method of the conversion code. The "Every" counting method records every conversion for which there has been a valid click through your ad(s) during conversion validation. In contrast, the "One-off" option only records the first conversion. A click can then only lead to one conversion. This setting applies individually per conversion code.  

Done

After clicking the “Save” button, the “Conversion Tracking” page should automatically refresh and the new conversion code should be available in the list.

Installing a conversion tag on your site

Integration

Integrate an <img> tag with the corresponding URL parameters in the <body> section on your website where the conversion should be tracked (e.g. on the booking confirmation page). It is easily possible to record different conversions by creating multiple conversion codes and integrating them where they occur.

The functioning integration code of your conversion codes can be viewed on the “Tools” > “Conversion Tracking” page in the Advertiser Front-End. Simply select the “Integration code” option in the “Actions” column of the desired conversion code.
