1. A branding element i.e. the logo
  2. A descriptive element i.e. Some text that grabs attention
  3. A call to action i.e. a button, something that visitors can use to take them further into your site
  4. A visualisation i.e. a screenshot, video or mood image
  5. A navigation element i.e. a menu to join other parts of the page

Pretty Simple really, but it’s about getting the visitor to be drawn into interacting with your site at a basic level to begin with.
