Today's sitemap webinar made me think about the disallow feature, seems opposite of sitemaps, but it also seems both are kind of ignored in varying ways by the engines.
I don't need help semantically, I got that part. I just can't seem to find a contemporary answer about what should be blocked using the robots.txt file.
For example, I have folders containing site comps for clients that I really don't want showing up in the SERPS. Is it better to not have these folders on the domain at all?
There are also security issues I've heard of that make sense, simply look at a site's robots file to see what they are hiding. It makes it easier to hunt for files when they know the directory the files are contained in. Do I concern myself with this?
Another example is a folder I have for my xml sitemap generator. I imagine google isn't going to try to index this or count it as content, so do I need to add folders like this to the disallow list?
