I'm working with a client who has a network of websites, each with content that will appeal to a specific audience. The issue we're having is that the client's flagship site will, for the foreseeable future, continue to receive visitors who are looking for the content earmarked for one of the client's OTHER sites.
As an example, imagine that the client is named Awesome Schools, and their flagship site awesomeschools.com has content that is about creating and nurturing awesome schools (it'd appeal to education policy makers, school administrators, etc), while their sister site awesometeachers.com has the content more likely to appeal to teachers (lesson plans, testimonials from other teachers, networking opportunities for teachers, etc.).
What is a good method for effectively getting teachers over to awesometeachers.com when they visit awesomeschools.com?
We're trying to avoid audience-based navigation within awesomeschools.com in favor of content-based navigation because while we're comfortable drawing a sharp line between practical content FOR educators and content ABOUT education (and having separate websites for the two audiences), we really don't want to be drawing lines that rigid within each site - we don't think those lines exist quite as rigidly once you get down below the site-to-site level.
