All digital content, especially on the web, is best considered Global until proven otherwise... especially when the content is in a widely spoken laguage like English. Below is a simple example of a hub and spokes strategy that may be helpful both to keep people in your company sane, to improve the experience of your users, and to improve things like SEO.

Depending on the medium (your corporate www site, facebook, twitter, etc.) and your company's size, you can set up some simple governance (standard naming protocol for local versus Global site, common URLs, templates, etc.) to drive productivity and also help capture local audiences with relevant local content but linking those sites to the Global site is usually key.

If your company or brand is big enough, consider a hub and spokes strategy for each of your key brands and each of your key mediums. For example:

• Create a Global Hub presense on Facebook "My Brand On Facebook"
• Create Local pages that hang off of the main Facebook site "My Brand On Facebook - Australia"
• Make sure your Local pages point heavily to your Global Hub for that medium (i.e. Facebook)
• Your Global Hub can then also promote the best content from around the world pulling from any of the Local sites and representing your Brand in a holistic, worldly and positive way.
