WebPage (schema.org)
The schema.org type WebPage classifies individual web pages, for example as a home page, search results page, contact page or FAQ page, and thereby tells search engines what kind of page they are dealing with.
In practice
WebPage is often used as an overarching frame into which other types such as BreadcrumbList, Article or Organization are embedded. More specific subtypes such as AboutPage, ContactPage or FAQPage give search engines an even clearer signal about the function of a page and should be preferred to the generic WebPage type wherever possible.
