Basically, I am going to be using the page referrer to display different content on a given page. It won't be the entire page depending on the referrer, but little aspects like the way titles are phrased or the topic of a feed displayed in the sidebar.
For example, let's say I have a website about animals. Now let's say someone Googles "bears" and clicks through to my page, and because the page detects that the referrer is a Google search for bears it shows more bear content. However, that same page will also show more content about lions if the referring page is a Google search for "lions". These "two" pages are located at the same web address. Can this page grow in search rankings for both topics even though it will only show one of the two types of pages based on the referring page?
