Create script for serving page by searched keyword

I'd like two server based scripts. The first would have the ability to insert a searched for keyword into the HTML of the page, as it is passed from Google Adwords. For example, user types in "MP3 Player" into Google, and if My Google Adwords is clicked on for this term, then user is take to page that reads something like: MP3 Player Resources where the actual script uses some kind of token in the HTML like <%Keyword%> that inserts the searched for term anywhere on the page that has that token in the HTML. Should be possible using server logs, or similar - as Google passes this information onto the server / stats. The second script would instead serve up the appropriate page on a site, that has already been optimized for the relevant keyword. For example, if user searches for "[Classic Mp3 Player][1]" and then clicks on my Ad for 'MP3 Players' which is pointed to <[login to view URL]> - then script would know to automatically forward visitor to this page: <[login to view URL]> Php or perl script ok, but php preferred. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
