What is Macro SEO?

[ellenwillss]

I heard this name first time in my SEO career. What is it exactly? How it is done and why to do it?

If we promote multiple website at a time, may be called as macro seo but I am not completely sure about it.

I am not getting any thing about this term as I read many thread about this macro SEO in many forum but not getting information related to it.
