larger SEO companies might not/won't/shouldn't want to reveal clients that they represent.

This always mystifies me.

How many ad agencies working in the print/tv/radio markets keep their client list a secret.

They don't.

The brag about who they represent. They often publish press releases when they sign a new client.

So why would a SEO want to keep their client list secret?
