Can spiders read layers <div> tags?

Layers instead of tables...any SEO problems in doing so?

[JamieBear]

Are there any SEO or keyword special considerations when you have layer code?

For example, will the spider read the entire layer?

Thanks!

I recently found out that the googlebot DO read layers, and what was more suprising to me, it was an invisible div...

Thanks, Nervo, for your reply.
