What is the purpose of application-name and keywords in meta tag?

Solution

According to HTML5 LC, a `meta` tag with `name=application-name` shall have value (in the `content` attribute) that is “short free-form string giving the name of the Web application that the page represents”; if the page is not an application, such a tag must not be used. Browsers “may use the application name in UI in preference to the page's `title`, since the title might include status messages and the like relevant to the status of the page at a particular moment in time instead of just being the name of the application.”

A `meta` tag with `name=keywords` specifies “a set of comma-separated tokens, each of which is a keyword relevant to the page”. It is normally ignored by search engines these days (and has never had an impact on browsers, as you can read between lines from the following note in HTML5 LC: “Many search engines do not consider such keywords, because this feature has historically been used unreliably and even misleadingly as a way to spam search engine results in a way that is not helpful for users.”
