Can anyone explain why one is better than the other, and in what circumstances? Things I’m considering: SEO consequences (if any), scaling issues (if any) and anything else I’m not thinking about.
Facebook, for example, uses subdirectories for profile pages. Tumblr uses subdomains. Are there specific reasons why?
Another consideration: domain mapping.
Hope the question isn’t too general, but I haven’t found a clear answer.
Thx.
First, the link for two gems for every Multisite expert or wannabe or in-between.
These free1 e-books are written by no less than two giants of Multisite: Mika Epstein (aka Ipstenu) and Andrea Rennick.
Here’s the snippet from the 101 that answers your question:
The Domain Mapping subject is extensively covered, so I’m pretty sure that the 101 reading will answer this and many other questions you may have.
