This thought is based on the assumption that google assigns searchers and websites to categories such as:
searcher: informational, transactional, navigational
websites: informational, transactional (ecom)
If a website uses mark-up on a page to identify a product (http://schema.org/Product) can/does/should that indicate that the website should receive visitors that have done searches that are transactional in nature?
