need to move already indexed pages to new URL

want to change the path and not lose visitors meanwhile

[walkman]

I did a few searches on wordtracker.com and found out that by naming my cgi script (part of URL) to a different keyword I could make more money. At least the new keyword is 4-5 times more likely to be found by visitors...according to their calculations.

The problem is that I don't want to lose any visitors in the process. Right now most people are coming from google via [domain.com...] pages. How can I best move those links (as far as google is concerned) to [domain.com...] They are hundreds of those pages, can't redirect them individually.

On my end, all I have to do make another copy of the script and name it, I can have more than one copy too, but I don't Google to penalize me for duplicate pages. I also will change the links on the pages that I have hardcoded the searches (so google indexes them).

Any advice? Also, would Google be nicer :) to me if i rewrote the URL /path to html?

thanks in advance....

thanks,
left everything where it is, just changed all the links (to them) to the new format. I'm hoping that Google will start replacing the indexed pages with the new ones.
