Your home page is unique because it is the one page where the design must account for the three main user archetypes (flirters, information-gatherers, and action-takers).
Before addressing these different user concerns, let’s run a simple test to see if your site is up to snuff:
Header Removal Test
If you remove the logo and tagline from your home page, will people still know what your site is about (without scrolling)?
If your site doesn’t pass the test, you may consider adding a feature box or a dedicated about section to your home page.
Or, if you really want to be a ninja, you can implement a combination of both :D
