When I track a sub id in CPV lab, it always appears...but with these weird letters after it like this:
ekmwpdtyz128z91537
How can I remove this stuff?
Is it possible that is the unique click ID being appended? As far as I know with CPVlab (I don't use it) you tell it to pass unique click ID and it appends it automatically to the end of your URL. So, usually you end your URL with something like ....subid4=. Without that it probably mashes it on to the end of your other subid. Example:
http://trackingurl.com/something.php?subid1=this&subid2=that
http://trackingurl.com/something.php?subid1=this&subid2=thatzerkblahzomg1263894723
http://trackingurl.com/something.php?subid1=this&subid2=that&subid3=
http://trackingurl.com/something.php?subid1=this&subid2=that&subid3=uniqueclickID
That could be it. I'll try it!
zenos answer is correct
I agree, that looks like it's probably the solution you're looking for! (And thanks to Zeno for that excellent explanation!)
Let us know if it does indeed fix the problem!
Hey all, quick update.
I BELIEVE Zeno is right, but I may have found an even easier way to solve this dumbass problem.

Per the CPV lab handbook, it attaches a sub id to each conversion or click so you can tell what the ID is of the person who made the click and categorize them based on their conversion habits (IE how far they are into your sales funnel, etc.)
With this button clicked, it is attaching the sub id to the end of all my links by default. Only problem is I don't have the stupid ass &subid= part Zeno recommended I use.
However, if this works, I should be able to skip all of that and just have CPV lab not attach ANYTHING to my links...(this is obviously the most convenient.)
I'll let you guys know if it works.
If you do that, it will mean that if you start rotating LPs, you won't be able to tell which LP is converting best, since you won't have unique subids to track by. However, if you don't need that, it's worth a go!
Personally I'd recommend tracking unique subids - it's not a big additional step and the data's very useful.
