I am designing the menu for a web site, and I was hoping to find an SEO-Friendly way to implement the Responsive Design used here:
Ask4Sam.net- Responsive Design Example
As you can see, for large resolutions the navigation menu is an unordered list of buttons, however to save space at smaller resolutions it becomes a drop-down menu.
However, I'm worried about duplicate menus and hidden content giving the site an SEO penalty. Is one of these techniques SEO-Friendly? Is there another technique that is better than these?
