Tracking pixels are a cookie-based solution, so they do not rely on the click ID being passed in an offer URL. The click ID value is stored in the initial cookie logged for that visitor, so conversion tracking will still work, even if the parameter was not passed to an offer. Tracking pixels are always placed after the conversion actually takes place, for example on the so called "Thank you" page.


How it works: 


The unique click ID value is generated for every user click then gets stored in a cookie file of the visitor's web browser. 

At the same time, the visitor is directed towards an offer via an offer URL. The click ID value does not have to be passed in the offer URL. The conversion tracking pixel has to be run after the conversion takes place, so when the visitor converts, this person will be directed towards another web page. This web page should host content relevant to the visitor that has just converted, so usually it displays a some kind of thanks to the visitor. That is why this web page is often called a "Thank you page".

The "Thank you" page will run the conversion tracking pixel. This feature comes in two forms:

  • Image pixel tag

  • iFrame pixel tag

Choosing the right form should be governed by the requirements of the "Thank you" page. However you implement it, the conversion tracking pixel will fetch the click ID value from a cookie and send a request to Trackerry with the information about conversion with the click ID value stored in the click ID parameter. This click ID will be used to match the conversion information with information about an original visit.


Important notice: 

Image pixel conversion is cookie based. If the users browser doesn't support cookie files or they are disabled, this tracking method will not work. 

Also your image pixel domain must match with your tracking (campaign) domain. 


How to set up Image Pixel tracking? 


Navigate to the System settings in the Upper Right corner of the Trackerry interface.

Select the Postbacks tab:


Select the Image pixel domain on the right side of the screen - it must match to your Campaign domain.


Another important note: 

HTTP pixel can only be used with HTTP campaign links

HTTPS pixel works with both HTTP and HTTPS campaign links



Then click

And copy the upper HTML tag (simple Image pixel) or the lower HTML tag (iframe image pixel). It should look like this: 

<img src="http://domain.com/image/3/?payout=PAYOUT&currency=USD&type=TYPE" style="display:none;" />


You can replace PAYOUT, CURRENCY and TYPE with the dynamic values if applicable, in order to insert CPA payouts values automatically.


The final step is to paste this code into the offer "Thank you page"
