I added the auto parts finder widget at here: http://www.autopartswar.com/year/1938/ And across the whole site of autopartswar.com. So I gave it a test by selecting the year, the make, the model and then click 'Go'. The URL I arrived at was something like this: http://www.amazon.com/2010-Acura-MDX/e/B004CGUJMW?_encoding=UTF8&carId= Which does NOT contain my associate ID nor the tracking ID: autopartswar-20. I contacted amazon associate support about this problem but they said it's all right. But I'm still having doubts about this. If the final URL the customer arrives at doesn't have my tracking ID or associate ID, how are they actually tracking if they are sent from me? Really weird. Anybody knows if I should keep using the auto parts finder widget?
Don't worry - your associateid already embedded into widget code. Just insert widget code to your webpage and promote it.
Thanks! I tried to examine all the http vars sent from my website when I'm clicking 'Go', seems they are all there! Just in the POST vars not GET vars where I can see in the address bar.
