Optimizely multi-site best practices: a presentation by MVP Ynze Nunnink
Separate global fields, site overrides and permissions and test change propagation. Check all referencing sites before removing shared content.

Putting content management into practice
A content model defines independently maintained and reusable information. Authoring, preview, approval and publication form a workflow; an API response validates only one part.
Checking the result
Have real editors create, change and restore content using long headings, missing fields and multiple languages. Record development dependencies and release ownership.
