Hey WordPress, What's on the Menu?
How to Get Started
The first place to start, if you haven't already done so, is to build the pages that your menu items will link to.
A typical header menu might look like:
HOME | BLOG | PRODUCTS | FREE STUFF | FAQ | ABOUT | CONTACT
It's a good idea to keep your header menu compact enough to fit on one line on a typical computer screen (your template should adjust it intelligently for a smartphone screen).
Note that you can change what's displayed as the the menu item from the default page name. I use this facility to display my header menu items in upper case (just a personal preference). So my About page is named About but I display it on the menu as ABOUT.
The typical footer menu will contain links to the pages that Google likes to see on every website, such as
and so on.
