As of today, there is no way to explicitly have Google index only certain parts of a single Webpage. I am writing this post in order to show my need for partial page indexing support and to discuss a few possible solutions for this today. 
My need for this stems from the Personalization of WebPages, a feature that makes the web better for people. I hope that this post can create discussion between us and maybe someone from Google will be kind enough chime in and provide us with guidelines on how to design websites where we want Google to ignore parts of a WebPage in their index.
