Hi Wes,
Yes the postback url is no problem, I was just asking how the pixel works, April says it will just look for the 202outbound php variable in the users cookie and update the campaign with the subid.
on another note, a question about google web optimizer (GWO). when i start a campaign i make some 202 text ads and get my Text links for PPC ads.
I make say two 202 landing pages to rotate in GWO, one for index.php and one for index2.php. In index.php I will send clicks to say go.php?v=1 and index2.php?v=2 the go.php uses a php switch statement and calls the 202 Get LP code for that landing page so i can see which lan page converts the best etc in 202 LP screen.
I will send all PPC clicks through say 1 text link I base off the first index.php landing page (which is just the index.php).
So i test my pages and find index2.php is the winner, so i make index2.php into index.php, make a nu variation and create two new 202 landing pages. I add the codes to my new index.php, index2.php and go.php, make the go.php?v=X right and setup GWO.
My question is, should everything track correctly doing this over and over? granted i end up with a long list of landing pages in LP screen, but I get to see page CR and CTR and know EXACTLY whats happenning (if this is working 100%), I seem to see the numbers but there are possibly a few anomalies like a lead showing up for a past landing page name, i just name them like 819index1 and 819index2 and use the same urls over and over (www.domain.com/index.php and index2.php). and I know im sending traffic through the latest LP codes...
I dont want to make new text links off the latest index.php LP code every time i want to run a test. do you see any problems with this? Any reason for possible data loss/confusion in the system?
