Anyone else track this?
huh? esplain more plz
Traffic comes in to landing page, loads prosper code. Surfer clicks and is redirected and the subid is not being passed.
Only thing I can tell is it has to be cookies, because that's how prosper gets the subid when you are redirecting to the offer.
Does that make sense?
Yeah it does make sense.
Is this for every click or only for a couple?
I always see some empty subids but that's about 1%-2% on avg on LI.
I get different %'s by hour of the day.
I think for me I was seeing its 15-20%. Seemed to be more IE 6/7 users than IE8+.
Since I log the useragent and subid, I know which causes it. At first I thought it was a prosper issue, but really they just set a cookie then read it on the redirect.
