SOLVED

DFA Tags firing twice

Avatar

Level 1

Hi everyone,

We have implemented a DTM rule to fire our floodlight tags. We are using a Page Load Rule and a Sequential Javascript:

var axel = Math.random() + "";

var a = axel * 10000000000000;

var b= _satellite.getVar('PageURL');

document.write('<iframe src="https://5118100.fls.doubleclick.net/activityi;src=5118100;type=footer;cat=foote0;u24=' + b + ';dc_lat=;dc_rdid=;tag_for_child_directed_treatment=;ord=' + a + '?" width="1" height="1" frameborder="0" style="display:none"></iframe>');

However, when we debug, we notice that there are two tags that fire with a minor difference:

One tag has the following variables:

1373142_pastedImage_2.png

and the other fires without the dc_pre variable:

1373141_pastedImage_1.png

Is there a reason for this? Is there a way we can do away with the other tag fire? What is the dc_pre variable?

Any help would be appreciated.

Thanks!

This is definitely not an issue with DTM functionality.

This seems to be just how Floodlight tagging works. Searching around on the internets, I found that a lot of others have asked this same question about floodlight tagging (regardless of how it is deployed, e.g. GTM vs. DTM vs. directly on page).  I could not find an explicit, definitive, or official answer about why it does this, though.  But I did find some interesting theories, namely in this thread:

The first one is probably a 302 redirect, check to see if that's the case. The second would result in a HTTP Status code of 200 if this is true.

If so, this isn't firing twice or duplicating data, its just redirecting in google.

@joshd7227840 and @aseelund

Thanks so much. I think the link shared and @aseelund's answer are pretty much the same explanation. Thank you very much for clearing this out for me.
