What should be the URL?

Should I optimize it for SEO or for tracking?

I know most of you would say that the URL's submitted for pay per click as not crawled by the crawlers, but I had a different experience recently.
Google did crawl my 313 pages .. which were exclusively for Adwords in the following format:
domain.com/index.php?Ad=Google&keyword=abcd

I was pre filling my search box on home page with keyword abcd.

As a result the HOME PAGE is dropped from google as each and every page of this different URL has same content expect the query box which is pre filled with keyword.

I do have individual page for each keyword on web site like domain.com/kw/abcd .. so now my dilemma is - weather is should use this url (..com/kw/abcd) for PPC ads so, if any crawler crawls them then I at least get some benefit or should I also ad some tracking on this URL (...?source=Google ) .. or FW .. or Overture etc to track the conversions?

Another thought is to use the following URL for PPC and then redirect it with 301:

domain.com/redirect/kw=abcd&source=google then redirect 301 to domain.com/kw/abcd

To me SEO and conversion tracking both are important factors?
