34627 Custom Headline From Adwords

I have a project that is very similiar, to one you've done in the past. What I need is... A very simple PHP script: no database link and no graphic user interface, to display custom headlines to people coming to my site clicking on one of my Adwords ads. For example, say that 1) you go to Google and type in the following query: “Blue Mustang 1969”, 2) My Adwords ad appears on the right side of the search engine interface and 3) you click on it. Then, my site would replace the following (or similar) HTML code: Keyword:Default Keyword} Here you will find info about {Keyword:Default Keyword} With the following: Blue Mustang 1969 Here you will find info about Blue Mustang 1969 If the user reaches the page without following my Adwords ad, then the Default Keyword will be displayed, as in: Default Keyword Here you will find info about Default Keyword It is a script for automatically increasing the relevance of my headlines. Requirements: The script should do the trick dissecting the Referrer variable. I don't want to modify my Adwords ads in any way. For example, [login to view URL] But should also work for localized Google queries [login to view URL] Thanks!
