Overview: The Distribution Tag defines the level of distribution of the present document

The distribution META tag defines the level or degree of distribution of your webpage and how it should be classified in relation to methods of distribution on the world wide web. There are currently only three forms of distribution supported by the distribution tag: Global (indicates that your webpage is intended for mass distribution to everyone), Local (intended for local distribution of your document), and IU - Internal Use (not intended for public distribution).

The Distribution Meta Tag is not a commonly used tag because most web page authors intend for their distribution to be set to everyone or for Global distribution. Nearly all webmasters can skip this tag unless you want to restrict the viewer size, in which most cases, using the Robots META tag is a better idea.
