Weaving a Tangled Web

Multiple tracking pixels can easily lead to serious migraines.

Within the affiliate marketing realm, tracking in real-time by using invisible 1x1 pixels is quite common place.  These pixels provide an easy and quite accurate method of recording actions that result from an affiliate link.  However, if you are an advertiser running your offers in multiple affiliate networks and you place multiple tracking pixels within the very same thank you page you already know the troubles this can cause – different sources claiming they were responsible for the very same sales! 

This is a huge head ache that can result in over payment to partners and frustration for everyone involved.  This happens because one tracking system can not know what another system is tracking.  Cookies set on behalf of one system/web site can not be read by another system.  This is an inherent security feature present in all web browsers.  So what can be done? 

In supporting our large and growing number of clients, Direct Response Technologies, has encountered this situation a number of times.  Many of our clients make use of other large affiliate networks to drive traffic.  As the volume of traffic sources increases, the likelihood that a consumer will be exposed to the same campaign from multiple sources increases.  Here is an example to illustrate the issue:

·         Partner A is a single affiliate with a very large mailing list.

·         Partner B is an affiliate network with thousands of affiliated publishers.

·         Partner B sets a 30 day cookie – they will track any sales generated within 30 days of the initial click.

·         The advertiser places both their internal tracking pixel on their thank you page and also the tracking pixel provided by Partner B.

·         The advertiser’s tracking system is configured to credit any sales to the last affiliate to generate a click – the one closest in time to the actual conversion.

·         Partner A mails the campaign out to their list of millions of subscribers.

·         Partner B has a number of affiliated publishers mail to their lists and promote it on their web sites.

·         Consumer X receives an email containing the campaign sent by one of Partner B’s affiliates and clicks but does not purchase.

·         A week later Consumer X receives an email containing the same campaign but sent by Partner A.  This time the consumer clicks and purchases.

Who should receive credit for the sale?  Partner B’s system is going to record the sale because of the 30 day cookie that was set when the consumer clicked on their ad, however, the advertiser’s system is going to credit the sale to Partner A, because that partner drove the click closest to the conversion.

Now the advertiser is in a tough position – either paying two different partners for the same sale or making Partner B unhappy by not paying them for the sale that was recorded in Partner B’s system but not within the advertiser’s.

To avoid this unfortunate situation, advertisers have a few options, including:

  • Dynamically creating the thank you page to only display the third-party pixel for the partner that will be credited with the sale.
  • Refusing to place third-party and forcing partners to work off of the advertiser’s numbers – in a lot of cases this is simply not a viable option.
  • Building intelligence into the pixel display process or making use of a tracking system that has this ability built in to it.


Dynamically creating your thank you page

One common approach savvy marketers use to avoid the headaches associated with multiple pixels, is to dynamically generate the thank you page.  In this scenario, the source of the traffic is typically identified by using a query string parameter, for example the link http://advertisers-site.com/?source=network1, would identify the source of the traffic as coming from network1.  The advertiser’s system then stores this information and displays the tracking code for network1 on the thank you page and only the tracking code for network1.  This assumes of course that the advertiser has the technical expertise to capture the query string parameter and to dynamically generate the thank you page.

One of the draw backs of this approach is that affiliates are only given credit for the sales/leads that are converted during that specific visit.   Sales derived from a subsequent visit are not able to be assigned.  This drives down the conversion rates for the partners and therefore reduces their satisfaction with the campaign.  However, the advertiser can be sure that the third-party system is not going to record sales that will be assigned to a different partner. 

Displaying pixels with intelligence

Client’s of DirectTrack™ now have an option that is just as easy to implement as the simple placing of a pixel, except that it adds a bit of intelligence to the process such that only those third parties that will be credited with the action have their pixels displayed. 

Within DirectTrack™, third party pixels are configured within the campaign, associating an HTML string with a particular partner account.  Then on the thank you page, a small piece of JavaScript is embedded.  This JavaScript determines which partner is going to be credited with the sale and then queries the database to obtain the proper code to display.  This method ensures that the sales recorded within DirectTrack match the sales that are recorded within the third party system – everybody gets what they need – accurate real time conversion information.  

In the example above, Partner A would receive credit for the sale and Partner B’s would not be shown.  If the time of the clicks is reversed (with Partner B generating the click closest to the conversion), then Partner B would be credited with the sale and their tracking code displayed thus recording the sale in both the advertiser’s and Partner B’s system.

Aspirin for those tracking headaches

DirectTrack’s method of supporting third-party tracking is welcome aspirin to ease tracking headaches.  Real-time conversion information is important and many affiliate networks will refuse to work with advertiser’s that are unwilling to place their tracking code.  The only viable options are to dynamically generate the thank you page to include the proper pixels or making use of a system like DirectTrack™ which provides a method to intelligently display the tracking codes.
