I have a bunch of hidden containers and I have been loading the titles with keywords; I was looking at the source code the other day and believe there is an 'invisibility' like that indicates that I have hidden content. Therefore, I starting thinking that this could be a bad thing. 

If you are going to hide the container, do you use a module title?  Any ideas whether or not this is viewed as a (+) or (-) in the grand scheme of things?

I was doing both - loading the container title, which is hidden, with a series of keywords | keywords | keywords. I also changed the container so that the module titles include header tags. Then, within the content of the container, I am also using titles and h1/2/3/4/5 tags.

I just assumed that a container that is set to 'invisible' and being loaded with keywords would count against me by the Google gods...not fond of hidden stuff on websites, I hear, given the abuse by spammers. I am now thinking that I should remove the titles on hidden containers, given that the source code reflects that I am 'hiding' something. 

Thoughts?

While it's not sooo directly related... I found that a much better practice is to always have Display Container selected and use "blank" container instead - all respectable skin makers are now including it. it allows for a better positioning control and style display. Not to mention that you get to see exactly what it looks like in Edit mode without having to switch over to View.
