Question about keyword level tracking using CJ "sid"

Hello All,

I hope I'm posting my question under the right forum. Following up to session 11 and session 12 of the black ink project, I had a question about keyword level tracking.

If I have an affiliate based website, and lets say that I create a landing page for a campaign - with my CJ affiliate links in it. Now, if I am using 10 keywords under 10 adgroups - all pointing to the same landing page, how can I track which keyword converted into a sale? I know we can track the "click through" for each keyword using analytics and adwords integration. However, if my landing page is same for all those 10 keywords - how would I set up the CJ "sid" - to allow me to track the keywords that generated a sale?

As far as my understanding goes - we can use one SID in our affiliate link, which can have one keyword/key phrase. So, does that mean that I would need to create separate landing pages for each keyword - with a unique SID based affiliate link on each of those landing page - to achieve keyword level tracking?

Thanks,
-Sid
