Your landing pages should have a specific goal in mind you want your website visitors to achieve. Often your visitors will be distracted by your other menu items and click away from your landing page never to return.
It's now possible to toggle both header and footer navigation menu items on and off for individual pages.
Browse to a page you want to configure on your website and click the settings button and "Configure this Page" option.
Now turn off either or both of the header and footer navigation. The header setting will hide everything in the header menu except your logo and the footer setting will hide all the social links and the standard footer navigation items in the footer.
Note: you can also configure these settings in the "Menu customization" tab on the platform settings page.
