Google offers a new customized/personalized search tool you can set up to search self-designated content.
Why might such a tool be useful? I suppose because you want to focus the search activities of users. Hence, I might want to offer a service allowing you to search this blog (and to do so in a more sophisticated way than would be allowed by the built-in search tool). Perhaps an educator might want to create a search tool focused on a specified body of content.
BTW – the Google ads on the search page do not generate revenue for the individual creating the customized search. I guess it is the charge for using the service. Fair enough.
