I have a CMS I've spent a *long* time working on (nearly two years) and it's really starting to take shape at this point. Because my main reason for building this is to support development of profitable websites, particularly with regard to heavy content, flexible advertising space, taking into account everything relevant to SEO marketers and so forth, I'd like to know what you guys have been missing.

The templating system is at least (if not more) flexible than any other CMS out there. So with regards to how the HTML is structured, don't worry about suggestions relating to general HTML on pages. These come out however you write the HTML. For those without much HTML knowledge, the CMS will come with a few standard HTML layouts to get people off to a quicker start.

Now I do have completely friendly URLs in, and there is a full versioning system so you have the entire history of edits to the page if you muck something up or want to undelete a page, etc.

So what would you want apart from that basic stuff?
301/302 redirects from deleted pages? from pages where you've changed the URL? (I'm not very knowledgeable on 301/302 yet because it hasn't been an issue for me so far)

What about AdSense stuff? Advertising stuff? What do you want in visitor logging/tracking?

Anything on your SEO/SEM wish list for a CMS would be appreciated.
