SEO Considerations with Submenus
Now that I've taken the step to update my sites with CSS menus to improve SEO, I'm wondering about how sub menus play in.
1. Are landing pages required or a good idea for the top level button?
2. Is it better to not have sub items, just link everything from the landing page?
3. Is bad to use both? (Especially in a particular scenario where all sub menu items would link directly to PDFs)
