"Want to offer your visitors search results that are tailored based on your site? With a few easy steps, you can customize search results based on the content of your website. Simply fill out a profile based on your site's content, generate the search box HTML, and then paste this HTML into your pages. Users who search from this search box will have the option to "flavor" their results based on the profile you've created." This is the way Google started the description of this service.

Site-flavored Google search is almost an anonymous service because it is still in beta and Google never presented it as a new service. However, what is Site-flavored Google search?

"Site-flavored Google search delivers web search results that are customized to individual websites. Simply fill out a profile describing your website's content, and when you add a site-flavored search box to your site, your users will get search results that are "flavored" to be more attuned to their interests," the company says in the description of the service.

"Our goal is to make all our search results as relevant as possible for all our users, and no two websites are alike. While standard Google results can be close most of the time, we think customization can make them even better," Google added.
