Can you put a single pixel tracking gif on the sales completion pages with commission junction? I do this with Azoogle but wondered if cj allows this too.
No, it's impossible to place any of your own tracking pixels on advertisers' sales completion pages through CJ. Some merchants may offer this feature directly if you drive enough traffic, but I've never seen any of them advertise that feature.
Yeh what is with those single pixel tracking thingys. I noticed them just recently when I stuck an ebay cj text link ad in one of my posts. Since I use one of the default blogger templates it automatically put a border around this 1 pixel gif so I went back to the post and deleted the img from the advert code. Does that now mean that this advert cant be tracked back to me!
The 1 pixel tracking images only track impressions - if you don't care about tracking impressions, don't worry about it. The OP wanted to know if he could add his own tracking pixel to the confirmation page (I think...) to track his conversions better.
