IF you have free content for teachers with no log in required to access the resources, you should consider becoming a tes "content partner." It is a great way to share your resources with the world of teaching. They can help you by getting feedback from the teachers and they can give you stats on how your resources are doing. It can help you drive traffic back to your site. Just be aware that quite a few US-based teacher resource providers are starting to join the TES network as they expand.
