Calling Page URLS and Keywords

Does anyone know if it is possible (and can actually provide an example code) which would return a page URL and then the keywords that resulted in people arriving at that page from the a search engine?

I would want to run this query against all the URLS on the website.

I have had a look and it doesnt look easy.You can get search words and you can get pages. I think it needs a away of looping through the found pages then doing another call to get the searches by filter.
However it prefers to give you a search by individual search terms, then pages. Reverse of what you need.

Sorry I couldnt help further.
